Adult attachment security and young adults’ dating relationships over time: Self-reported, observational, and physiological evidence.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

This study examined the developmental significance of adult attachment security—as measured by the Adult Attachment Interview—for romantic relationship functioning concurrently and approximately 1 year later in a sample of heterosexual dating couples between the ages of 18 and 25 (115 dyads at Time 1 [T1] and 57 dyads at T2, 74% White). The authors assessed romantic relationship functioning at T1 and T2 using observers’ ratings of emotional tone during a laboratory conflict resolution task and via participants’ self-reports about their relationships, yielding evidence that adult attachment security prospectively predicted the observed and perceived quality of adults’ romantic relationships even after prior levels of interpersonal functioning were controlled. Measures of autonomic...

Numerical estimation in preschoolers.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

Children’s sense of numbers before formal education is thought to rely on an approximate number system based on logarithmically compressed analog magnitudes that increases in resolution throughout childhood. School-age children performing a numerical estimation task have been shown to increasingly rely on a formally appropriate, linear representation and decrease their use of an intuitive, logarithmic one. We investigated the development of numerical estimation in a younger population (3.5- to 6.5-year-olds) using 0–100 and 2 novel sets of 1–10 and 1–20 number lines. Children’s estimates shifted from logarithmic to linear in the small number range, whereas they became more accurate but increasingly logarithmic on the larger interval. Estimation accuracy was correlated with knowle...

Individual differences in executive function and central coherence predict developmental changes in theory of mind in autism.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

In this study, the longitudinal relationships among these 3 aspects of cognition in autism were investigated. Thirty-seven cognitively able children with an autism spectrum condition were assessed on tests targeting ToM (false-belief prediction), EF (planning ability, cognitive flexibility, and inhibitory control), and CC (local processing) at intake and again 3 years later. Time 1 EF and CC skills were longitudinally predictive of change in children’s ToM test performance, independent of age, language, nonverbal intelligence, and early ToM skills. Predictive relations in the opposite direction were not significant, and there were no developmental links between EF and CC. Rather than showing problems in ToM, EF and CC as co-occurring and independent atypicalities in autism, these finding...

Antipathetic relationships in child and adolescent development: A meta-analytic review and recommendations for an emerging area of study.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

Antipathetic relationships, or relationships based on mutual dislike, have received less attention than other aspects of children’s peer relations. The present meta-analytic review summarizes the existing literature (26 studies consisting of over 23,000 children and adolescents) to illuminate the prevalence of antipathetic relationships and their associations with maladjustment. Results indicate that 35% of children have an antipathetic relationship and that antipathetic relationships are associated with externalizing and internalizing problems, low academic achievement, low prosocial behavior, victimization and rejection by peers, and lower positive peer regard (e.g., social preference) and friendships. Gender differences in antipathetic relationships are trivial, and antipathetic relat...

Enhancing building, conversation, and learning through caregiver–child interactions in a children’s museum.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

The authors adapted an experimental design to examine effects of instruction prior to entry into a children’s museum exhibit on caregiver–child interactions and children’s learning. One hundred twenty-one children (mean age = 6.6 years) and their caregivers were randomly assigned to 1 of 5 conditions that varied according to what, if any, preexhibit instruction the dyads received: (a) building and conversation instruction, (b) building instruction only, (c) conversation instruction only, (d) presentation of models of buildings and conversations without instruction, or (e) no instruction or control. Building instruction included information about triangular cross-bracing. Conversation instruction emphasized the use of elaborative wh-questions and associations. When observed in the exh...

Links between friendship relations and early adolescents’ trajectories of depressed mood.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

The present study examined to what extent different types of friendship experiences (i.e., friendlessness, having depressed friends, and having nondepressed friends) are associated with early adolescents’ longitudinal trajectories of depressed mood. On the basis of a sample of 201 youths (108 girls, 93 boys), we identified 3 distinct longitudinal profiles of depressed mood from Grade 5 (age 11) through Grade 7 (age 13): one group with consistently low levels of depressed mood, another group showing a sharp increase in depressed mood from late childhood through early adolescence, and a 3rd group with consistently high levels of depressed mood from late childhood through early adolescence. Subsequent analyses revealed that, compared to friendless youths, youths with nondepressed friends sh...

Reflecting on self-relevant experiences: Adult age differences.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

A broad array of research findings suggest that older adults, as compared with younger adults, have a more positive sense of self and possibly a clearer and more consistent sense of self. Further, older adults report lower motivation to construct or maintain a sense of self. In the present study, we examined whether such differences in self-views were reflected in features of older and younger adults’ narratives and narrating practices around recent, self-relevant events. Narratives about self-discrepant and self-confirming events were elicited from a sample of younger (18–37 years of age; n = 115) and older (58–90 years of age; n = 62) adults and were compared for indicators of engagement in self-construction, meanings, and emotionality. Older adults’ narratives contained signific...

The behavioral development of Korean children in institutional care and international adoptive families.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

In this study, the authors compared the behavioral development of 4- to 8-year-old South Korean children placed in institutional care (n = 230) or adopted internationally (n = 382), with age of entry, parental status, reason for institutionalization, and postinstitutionalization parental contact as risk factors for institutionalized children. There was a placement effect of adoption and support for age of entry and parental status as risk factors. Relinquished children institutionalized before age 2 fared the poorest across groups. Children institutionalized after age 2 with deceased/unknown parents fared best among institutionalized children. Institutionalization due to family disruption was a risk for relinquished children only, whereas parental contact did not increase the risk for beha...

Parent–child and triadic antecedents of children’s social competence: Cultural specificity, shared process.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

Guided by theories of cultural participation, the authors examined mother–child, father–child, and triadic interactive behaviors in 141 Israeli and Palestinian couples and their firstborn child at 5 and 33 months as antecedents of children’s social competence. Four parent–child measures (parent sensitivity, child social engagement, parental control, dyadic reciprocity) and two family-level measures (cohesion and rigidity) were coded at each age. Children’s social competence was observed at child-care locations. Cultural differences were observed for parent sensitivity and child social engagement, and the large cultural differences in sensitivity observed in infancy were attenuated by the toddler age. Interactive behaviors correlated with culture-specific parenting practices, chil...

The early development of object knowledge: A study of infants’ visual anticipations during action observation.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

This study examined the developing object knowledge of infants through their visual anticipation of action targets during action observation. Infants (6, 8, 12, 14, and 16 months) and adults watched short movies of a person using 3 different everyday objects. Participants were presented with objects being brought either to a correct or to an incorrect target location (e.g., cup to mouth, phone to ear vs. cup to ear, brush to mouth). When observing the action sequences, infants as well as adults showed anticipatory fixations to the target areas of the displayed actions. For all infant age-groups, there were differences in anticipation frequency between functional and nonfunctional object–target combinations. Adults exhibited no effect of object–target combination, possibly because they ...

Correction to McCartney et al. (2010).

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

Preschoolers (sometimes) defer to the majority in making simple perceptual judgments.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

Three- and 4-year-old children were asked to judge which of a set of 3 lines was the longest, both independently and in the face of an inaccurate consensus among adult informants. Children were invariably accurate when making independent judgments but sometimes deferred to the inaccurate consensus. Nevertheless, the deference displayed by both age groups proved to be circumscribed. When asked to solve a practical problem—selecting the longest strip to build an adequate bridge—both groups relied on their own perceptual judgment, regardless of whether they had deferred to the inaccurate consensus. Confirming earlier meta-analytic findings with adults, the rate of deference was greater among Asian American children as compared with Caucasian American children. (PsycINFO Database Record (c...

The effects of intersensory redundancy on attention and memory: Infants’ long-term memory for orientation in audiovisual events.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

This research examined the effects of bimodal audiovisual and unimodal visual stimulation on infants’ memory for the visual orientation of a moving toy hammer following a 5-min, 2-week, or 1-month retention interval. According to the intersensory redundancy hypothesis (L. E. Bahrick & R. Lickliter, 2000; L. E. Bahrick, R. Lickliter, & R. Flom, 2004) detection of and memory for nonredundantly specified properties, including the visual orientation of an event, are facilitated in unimodal stimulation and attenuated in bimodal stimulation in early development. Later in development, however, nonredundantly specified properties can be perceived and remembered in both multimodal and unimodal stimulation. The current study extended tests of these predictions to the domain of memory in infants of...

Serial-order short-term memory predicts vocabulary development: Evidence from a longitudinal study.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

This study investigated longitudinal predictions between serial-order STM and vocabulary development. Tasks maximizing the temporary retention of either serial-order or item information were administered to kindergarten children aged 4 and 5. At age 4, age 5, and from age 4 to age 5, serial-order STM capacities, but not item STM capacities, were specifically associated with vocabulary development. Moreover, the increase of serial-order STM capacity from age 4 to age 5 predicted the increase of vocabulary knowledge over the same time period. These results support a theoretical position that assumes an important role for serial-order STM capacities in vocabulary acquisition.

Polymorphisms in dopamine system genes are associated with individual differences in attention in infancy.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

This study investigated the effects of polymorphisms in four dopamine system genes on performance in a task developed to assess such functioning, the Freeze-Frame task, at 9 months of age. Polymorphisms in the catechol-O-methyltransferase (COMT) and the dopamine D4 receptor (DRD4) genes are likely to impact directly on the functioning of the frontal cortex, whereas polymorphisms in the dopamine D2 receptor (DRD2) and dopamine transporter (DAT1) genes might influence frontal cortex functioning indirectly via strong frontostriatal connections. A significant effect of the COMT valine¹58methionine (Val158Met) polymorphism was found. Infants with the Met/Met genotype were significantly less distractible than infants with the Val/Val genotype in Freeze-Frame trials presenting an engaging centra...

Conditional reasoning in autism: Activation and integration of knowledge and belief.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

This study explored whether adolescents with autism spectrum disorder (ASD; N = 26) were less influenced by background knowledge than typically developing adolescents (N = 38) when engaged in conditional reasoning. Participants were presented with pretested valid and invalid conditional inferences with varying available counterexamples. The group with ASD showed significantly less influence of prior knowledge on valid inferences (p = .01) and invalid inferences (p = .01) compared with the typical group. In a secondary probability judgment task, no significant group differences were found in probabilistic judgments of the believability of the premises. Further experiments found that results could not be explained by differences between the groups in the ability to generate counterexamples o...

Differential susceptibility to parenting and quality child care.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

Research on differential susceptibility to rearing suggests that infants with difficult temperaments are disproportionately affected by parenting and child care quality, but a major U.S. child care study raises questions as to whether quality of care influences social adjustment. One thousand three hundred sixty-four American children from reasonably diverse backgrounds were followed from 1 month to 11 years with repeated observational assessments of parenting and child care quality, as well as teacher report and standardized assessments of children’s cognitive-academic and social functioning, to determine whether those with histories of difficult temperament proved more susceptible to early rearing effects at ages 10 and 11. Evidence for such differential susceptibility emerges in the c...

Early predictors of sexually intimate behaviors in an urban sample of young girls.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

In recent years, concern has been raised about girls’ involvement in sexual activity at progressively younger ages. Little is known about the prevalence of emerging intimate behaviors, the psychosocial factors associated with these behaviors, or the moderating effects of ethnicity on these associations in early adolescence. In the current prospective study, we examined the prevalence and predictors of sexually intimate behaviors at age 12 years in an urban community sample of 1,116 ethnically diverse girls. Cluster analysis revealed 3 groups at age 12: no sexual behavior, mild behavior (e.g., holding hands), and moderate behavior (e.g., laying together). Minority status girls reported higher rates of both mild and moderate sexually intimate behaviors compared with European American girls...

The development of object categorization in young children: Hierarchical inclusiveness, age, perceptual attribute, and group versus individual analyses.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

Multiple levels of category inclusiveness in 4 object domains (animals, vehicles, fruit, and furniture) were examined using a sequential touching procedure and assessed in both individual and group analyses in eighty 12-, 18-, 24-, and 30-month-olds. The roles of stimulus discriminability and child motor development, fatigue, and actions were also investigated. More inclusive levels of categorization systematically emerged before less inclusive levels, and a consistent advantage for categorizing high versus low perceptual contrasts was found. Group and individual analyses generally converged, but individual analyses added information about child categorization over group analyses. The development of object categorization in young children is discussed in light of efficiency of processing a...

The development of attentional networks: Cross-sectional findings from a life span sample.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

Using a population-based sample of 263 individuals ranging from 6 to 89 years of age, we investigated the gains and losses in the abilities to (a) use exogenous cues to shift attention covertly and (b) ignore conflicting information across the life span. The participants’ ability to shift visual attention was tested by a typical Posner-type orienting task with valid and invalid peripheral cues. To tap conflict resolution, we asked participants to perform a color version of the Eriksen-type flanker task. The observed cross-sectional age differences in our data indicate that the ability to deal with conflicting information and the ability to covertly orient attention show different cross-sectional age gradients during childhood and that only conflict resolution mechanisms show a marked neg...

Locomotor expertise predicts infants’ perseverative errors.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

This research examined the development of inhibition in a locomotor context. In a within-subjects design, infants received high- and low-demand locomotor A-not-B tasks. In Experiment 1, walking 13-month-old infants followed an indirect path to a goal. In a control condition, infants took a direct route. In Experiment 2, crawling and walking 13-month-old infants crawled through a tunnel to reach a goal at the other end and received the same control condition as in Experiment 1. In both experiments, perseverative errors occurred more often in the high-demand condition than in the low-demand condition. Moreover, in Experiment 2, walkers perseverated more than crawlers, and extent of perseveration was related to infants’ locomotor experience. In Experiment 3, the authors addressed a possible...

Conflict resolution in the parent–child, marital, and peer contexts and children’s aggression in the peer group: A process-oriented cultural perspective.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

Theories of socialization propose that children’s ability to handle conflicts is learned at home through mechanisms of participation and observation—participating in parent–child conflict and observing the conflicts between parents. We assessed modes of conflict resolution in the parent–child, marriage, and peer-group contexts among 141 Israeli and Palestinian families and their 1st-born toddler. We observed the ecology of parent–child conflict during home visits, the couple’s discussion of marital conflicts, and children’s conflicts with peers as well as aggressive behavior at child care. Israeli families used more open-ended tactics, including negotiation and disregard, and conflict was often resolved by compromise, whereas Palestinian families tended to consent or object. ...

Children reason about shared preferences.

Developmental Psychology — Mon, 08 Mar 2010 05:00:00 +0100

Two-year-old children’s reasoning about the relation between their own and others’ preferences was investigated across two studies. In Experiment 1, children first observed 2 actors display their individual preferences for various toys. Children were then asked to make inferences about new, visually inaccessible toys and books that were described as being the favorite of each actor, unfamiliar to each actor, or disliked by each actor. Children tended to select the favorite toys and books from the actor who shared their own preference but chose randomly when the new items were unfamiliar to or disliked by the two actors. Experiment 2 extended these findings, showing that children do not generalize a shared preference across unrelated categories of items. Taken together, the results sugg...

Gender differences in keeping secrets from parents in adolescence.

Developmental Psychology — Tue, 05 Jan 2010 16:14:40 +0100

The current longitudinal study examined adolescent gender differences in the developmental changes and relational correlates of secrecy from parents. For 4 successive years, starting in the second year of junior high (mean age at Time 1 = 13.2 years, SD = 0.51), 149 male and 160 female Dutch adolescents reported on secrecy from their parents and the quality of the parent–child relationship. Latent growth curve modeling revealed a linear increase in secrecy, which was significantly faster for boys than for girls. Moreover, cross-lagged panel analyses showed clear concurrent and longitudinal linkages between secrecy from parents and poorer parent–child relationship quality in girls. In boys, much less strong linkages were found between poorer relationships and secrecy from parents. (Psyc...

Infants prefer the musical meter of their own culture: A cross-cultural comparison.

Developmental Psychology — Tue, 05 Jan 2010 16:14:40 +0100

We presented 4- to 8-month-old American and Turkish infants with contrasting melodies to determine whether cultural background would influence their preferences for musical meter. In Experiment 1, American infants preferred Western over Balkan meter, whereas Turkish infants, who were familiar with both Western and Balkan meters, exhibited no preference. Experiments 2 and 3 presented infants with either a Western or Balkan meter paired with an arbitrary rhythm with complex ratios not common to any musical culture. Both Turkish and American infants preferred Western and Balkan meter to an arbitrary meter. Infants’ musical preferences appear to be driven by culture-specific experience and a culture-general preference for simplicity. (PsycINFO Database Record (c) 2009 APA, all rights reserve...

Exploring developmental differences in visual short-term memory and working memory.

Developmental Psychology — Tue, 05 Jan 2010 16:14:39 +0100

Although visuospatial short-term memory tasks have been found to engage more executive resources than do their phonological counterparts, it remains unclear whether this is due to intrinsic differences between the tasks or differences in participants’ experience with them. The authors found 11-year-olds’ performances on both visual short-term and working memory tasks to be more greatly impaired by an executive suppression task (random number generation) than were those of 8-year-olds. Similar findings with adults (e.g., Kane & Engle, 2000) suggest that the imposition of a suppression task may have overloaded the older children’s executive resources, which would otherwise be used for deploying strategies for performing the primary tasks. Conversely, the younger children, who probably ...

Development of intuitions about support beyond infancy.

Developmental Psychology — Tue, 05 Jan 2010 16:14:39 +0100

In a series of 3 experiments modeled after infant studies, 3- to- 6-year-old children’s intuitive knowledge about support was assessed. Different objects were shown either sufficiently supported or not. Children had to predict whether a block would remain standing on a platform upon release or make perceptual judgments about the possibility of a shown block-on-platform configuration. Overall, performance was strongly age-related and independent of task context. Sensitivity for the amount of contact between object and support was clearly evidenced for each of the age-groups tested and was almost perfect in 5- and 6-year-olds. By contrast, sensitivity for the proportion of an object’s volume positioned over the support was only marginally reliable in 3-year-olds and still far from perfec...

Adolescents’ occupational and educational aspirations and expectations: Links to high school activities and adult educational attainment.

Developmental Psychology — Tue, 05 Jan 2010 16:14:39 +0100

This longitudinal study explored adolescents’ future-oriented cognitions, current activities, and later educational attainment using data from 317 adolescents (55% female; mean age = 14.98 years, SD = 0.85) followed into early adulthood. Aspirations and expectations regarding work and education showed modest stability from year to year. Exploration of the reciprocal relations between these cognitions and adolescents’ activities supported both unidirectional and bidirectional effects, with different patterns emerging for aspirations and expectations. In multiple regression analyses, future-oriented cognitions predicted adult educational attainment; follow-up analyses indicated that the effect of adolescents’ expectations was partially mediated by participation in extracurricular activ...

Where self-control comes from: On the development of self-control and its relationship to deviance over time.

Developmental Psychology — Tue, 05 Jan 2010 16:14:38 +0100

The current study tested a set of interrelated theoretical propositions based on self-control theory (M. R. Gottfredson & T. Hirschi 1990). Data were collected on 1,155 children at 4.5 years, at 8.5 years (3rd grade), and at 10.5 years (5th grade) as part of the National Institute of Child Health and Human Development longitudinal study over a 6-year period. Findings based on simple structural equation models and latent growth modeling of developmental trajectories suggest that (a) there was great construct stability of self-control and deviance over the 6-year period, (b) there was positive growth in self-control trajectory over time, (c) parenting predicted this trajectory but also explained variability in self-control at initial status, (d) there was a declining deviance trajectory over...

The cognitive processes underlying event-based prospective memory in school-age children and young adults: A formal model-based study.

Developmental Psychology — Tue, 05 Jan 2010 16:14:35 +0100

Fifty children 7 years of age (29 girls, 21 boys), 53 children 10 years of age (29 girls, 24 boys), and 36 young adults (19 women, 17 men) performed a computerized event-based prospective memory task. All 3 groups differed significantly in prospective memory performance, with adults showing the best performance and with 7-year-olds showing the poorest performance. We used a formal multinomial process tree model of event-based prospective memory to decompose age differences in cognitive processes that jointly contribute to prospective memory performance. The formal modeling results demonstrate that adults differed significantly from the 7-year-olds and the 10-year-olds on both the prospective component and the retrospective component of the task. The 7-year-olds and the 10-year-olds differe...

Do children profit from looking beyond looks? From similarity-based to cue abstraction processes in multiple-cue judgment.

Developmental Psychology — Tue, 05 Jan 2010 16:14:35 +0100

The authors investigated the ability of 9- to 11-year-olds and of adults to use similarity-based and rule-based processes as a function of task characteristics in a task that can be considered either a categorization task or a multiple-cue judgment task, depending on the nature of the criterion (binary vs. continuous). Both children and adults relied on similarity-based processes in the categorization task. However, adults relied on cue abstraction in the multiple-cue judgment task, whereas the majority of children continued to rely on similarity-based processes. Reliance on cue abstraction resulted in better judgments for adults but not for children in the multiple-cue judgment task. This suggests that 9- to 11-year-olds may have defaulted to similarity-based processes because they were n...

Narrative and ethnic identity exploration: A longitudinal account of emerging adults’ ethnicity-related experiences.

Developmental Psychology — Tue, 05 Jan 2010 16:14:35 +0100

Age differences in affective decision making as indexed by performance on the Iowa Gambling Task.

Developmental Psychology — Tue, 05 Jan 2010 16:14:35 +0100

Contemporary perspectives on age differences in risk taking, informed by advances in developmental neuroscience, have emphasized the need to examine the ways in which emotional and cognitive factors interact to influence decision making. In the present study, a diverse sample of 901 individuals between the ages of 10 and 30 were administered a modified version of the Iowa Gambling Task, which is designed to measure affective decision making. Results indicate that approach behaviors (operationalized as the tendency to play increasingly from the advantageous decks over the course of the task) display an inverted U-shape relation to age, peaking in mid- to late adolescence. In contrast, avoidance behaviors (operationalized as the tendency to refrain from playing from the disadvantageous decks...

The developmental relations between conceptual and procedural knowledge: A multimethod approach.

Developmental Psychology — Tue, 05 Jan 2010 16:14:35 +0100

Interactions between conceptual and procedural knowledge influence the development of mathematical competencies. However, after decades of research, these interrelations are still under debate, and empirical results are inconclusive. The authors point out a source of these problems. Different kinds of knowledge and competencies only show up intertwined in behavior, making it hard to measure them validly and independently of each other. A multimethod approach was used to investigate the extent of these problems. A total of 289 fifth and sixth graders’ conceptual and procedural knowledge about decimal fractions was measured by 4 common hypothetical measures of each kind of knowledge. Study 1 tested whether treatments affected the 2 groups of measures in consistent ways. Study 2 assessed, a...

Children’s response to adult disgust elicitors: Development and acquisition.

Developmental Psychology — Tue, 05 Jan 2010 16:14:35 +0100

Little is known about when or how different disgust elicitors are acquired. In Study 1, parents of children (0–18 years old) rated how their child would react to 22 disgust elicitors. Different developmental patterns were identified for core, animal, and sociomoral elicitors, with core elicitors emerging first. In Study 2, children (2–16 years old) were exposed alone and then with their parent to a range of elicitors derived from Study 1. Self-report, behavioral, and facial expression data were obtained along with measures of contagion, conservation, and contamination. Convergent evidence supported the developmental patterns reported in Study 1. Evidence for parent–child transmission was also observed, with parents of young children emoting more disgust to their offspring and showing...

Early childhood family structure and mother–child interactions: Variation by race and ethnicity.

Developmental Psychology — Tue, 05 Jan 2010 16:14:35 +0100

With data from the Early Childhood Longitudinal Study–Birth Cohort (n = 6,449), a nationally representative sample of births in 2001, we used hierarchical linear modeling to analyze differences in observed interactions between married, cohabiting, never-married, and divorced mothers and their children. In contrast to previous studies, we concentrated on early childhood, a developmentally critical period that has been understudied in the family structure literature, and relied on objective observational measures of mother–child interactions, which are unlikely to be biased by maternal perceptions of interactions with children. Nonmarital family structures were common in the lives of young children, as 32% lived outside of a married, biological parent home. Initial results indicated that...

A longitudinal study of conversations with parents about sex and dating during college.

Developmental Psychology — Tue, 05 Jan 2010 16:14:35 +0100

This study provides a longitudinal analysis of 30 young adults’ (17 women, 13 men) sexual experiences, attitudes about sexuality and dating, and reported conversations with parents about sexuality and dating from the 1st and 4th years of college. Self-report questionnaires revealed increases in general closeness with parents, increases in sexual and dating experiences, and more sexually permissive as well as more gender stereotyped attitudes. Qualitative analyses of individual interviews indicated a movement from unilateral and restrictive sex-based topics to more reciprocal and relationship-focused conversations over time. Gender analyses revealed that young women reported more restrictive sex messages and young men more positive sex messages. Participants also described increased openn...

Systems in development: Motor skill acquisition facilitates three-dimensional object completion.

Developmental Psychology — Tue, 05 Jan 2010 16:14:35 +0100

How do infants learn to perceive the backs of objects that they see only from a limited viewpoint? Infants’ 3-dimensional object completion abilities emerge in conjunction with developing motor skills—independent sitting and visual–manual exploration. Infants at 4.5 to 7.5 months of age (n = 28) were habituated to a limited-view object and tested with volumetrically complete and incomplete (hollow) versions of the same object. Parents reported infants’ sitting experience, and infants’ visual–manual exploration of objects was observed in a structured play session. Infants’ self-sitting experience and visual–manual exploratory skills predicted looking at the novel, incomplete object on the habituation task. Further analyses revealed that self-sitting facilitated infants’ vi...

The development of reproductive strategy in females: Early maternal harshness ? earlier menarche ? increased sexual risk taking.

Developmental Psychology — Tue, 05 Jan 2010 16:14:35 +0100

To test a proposition central to J. Belsky, L. Steinberg, and P. Draper’s (1991) evolutionary theory of socialization—that pubertal maturation plays a role in linking early rearing experience with adolescent sexual risk taking (i.e., frequency of sexual behavior) and, perhaps, other risk taking (e.g., alcohol, drugs, delinquency)—the authors subjected longitudinal data on 433 White, 62 Black, and 31 Hispanic females to path analysis. Results showed (a) that greater maternal harshness at 54 months predicted earlier age of menarche; (b) that earlier age of menarche predicted greater sexual (but not other) risk taking; and (c) that maternal harshness exerted a significant indirect effect, via earlier menarche, on sexual risk taking (i.e., greater harshness ? earlier menarche ? greater s...

Discrimination of phonemic vowel length by Japanese infants.

Developmental Psychology — Tue, 05 Jan 2010 16:14:34 +0100

Japanese has a vowel duration contrast as one component of its language-specific phonemic repertory to distinguish word meanings. It is not clear, however, how a sensitivity to vowel duration can develop in a linguistic context. In the present study, using the visual habituation–dishabituation method, the authors evaluated infants’ abilities to discriminate Japanese long and short vowels embedded in two-syllable words (/mana/ vs. /ma:na/). The results revealed that 4-month-old Japanese infants (n = 32) failed to discriminate the contrast (p = .676), whereas 9.5-month-olds (n = 33) showed the discrimination ability (p = .014). The 7.5-month-olds did not show positive evidence to discriminate the contrast either when the edited stimuli were used (n = 33; p = .275) or when naturally utter...

Global–local and trail-making tasks by monolingual and bilingual children: Beyond inhibition.

Developmental Psychology — Tue, 05 Jan 2010 16:14:34 +0100

In 3 experiments, a total of 151 monolingual and bilingual 6-year-old children performed similarly on measures of language and cognitive ability; however, bilinguals solved the global–local and trail-making tasks more rapidly than monolinguals. This bilingual advantage was found not only for the traditionally demanding conditions (incongruent global–local trials and Trails B) but also for the conditions not usually considered to be cognitively demanding (congruent global–local trials and Trails A). All the children performed similarly when congruent trials were presented in a single block or when perceptually simple stimuli were used, ruling out speed differences between the groups. The results demonstrate a bilingual advantage in processing complex stimuli in tasks that require exec...

A new look at children’s understanding of mind and emotion: The case of prayer.

Developmental Psychology — Tue, 05 Jan 2010 16:14:34 +0100

Multiple methods were used to examine children’s awareness of connections between emotion and prayer. Four-, 6-, and 8-year-olds and adults (N = 100) predicted whether people would pray when feeling different emotions, explained why characters in different situations decided to pray, and predicted whether characters’ emotions would change after praying. Four- and 6-year-olds exclusively judged that positive emotions motivate prayer, whereas 8-year-olds and adults most often predicted that negative emotions would cause people to pray and that praying could improve emotions. There was also a significant increase between 4 and 8 years in explaining prayer as motivated by need for assistance, for thanksgiving, and for conversation, as well as for explaining postprayer emotions in relation ...

Infant perception of audio-visual speech synchrony.

Developmental Psychology — Tue, 05 Jan 2010 16:14:34 +0100

Three experiments investigated perception of audio-visual (A-V) speech synchrony in 4- to 10-month-old infants. Experiments 1 and 2 used a convergent-operations approach by habituating infants to an audiovisually synchronous syllable (Experiment 1) and then testing for detection of increasing degrees of A-V asynchrony (366, 500, and 666 ms) or by habituating infants to a detectably asynchronous syllable (666 ms; Experiment 2) and then testing for detection of decreasing degrees of asynchrony (500, 366, and 0 ms). Following habituation to the synchronous syllable, infants detected only the largest A-V asynchrony (0 ms vs. 666 ms), whereas following habituation to the asynchronous syllable, infants detected the largest asynchrony (666 ms vs. 0 ms) as well as a smaller one (666 ms vs. 366 ms)...

Learning the rules: Observation and imitation of a sorting strategy by 36-month-old children.

Developmental Psychology — Tue, 05 Jan 2010 16:14:34 +0100

Two experiments were used to investigate the scope of imitation by testing whether 36-month-olds can learn to produce a categorization strategy through observation. After witnessing an adult sort a set of objects by a visible property (their color; Experiment 1) or a nonvisible property (the particular sounds produced when the objects were shaken; Experiment 2), children showed significantly more sorting by those dimensions relative to children in control groups, including a control in which children saw the sorted endstate but not the intentional sorting demonstration. The results show that 36-month-olds can do more than imitate the literal behaviors they see; they also abstract and imitate rules that they see another person use.

Adolescent peer relationships and behavior problems predict young adults’ communication on social networking websites.

Developmental Psychology — Tue, 05 Jan 2010 16:14:34 +0100

This study examined online communication on social networking web pages in a longitudinal sample of 92 youths (39 male, 53 female). Participants’ social and behavioral adjustment was assessed when they were ages 13–14 years and again at ages 20–22 years. At ages 20–22 years, participants’ social networking website use and indicators of friendship quality on their web pages were coded by observers. Results suggested that youths who had been better adjusted at ages 13–14 years were more likely to be using social networking web pages at ages 20–22 years, after statistically controlling for age, gender, ethnicity, and parental income. Overall, youths’ patterns of peer relationships, friendship quality, and behavioral adjustment at ages 13–14 years and at ages 20–22 years pr...

Analyzing true change in longitudinal multitrait-multimethod studies: Application of a multimethod change model to depression and anxiety in children.

Developmental Psychology — Tue, 05 Jan 2010 16:14:34 +0100

The authors show how structural equation modeling can be applied to analyze change in longitudinal multitrait-multimethod (MTMM) studies. For this purpose, an extension of latent difference models (McArdle, 1988; Steyer, Eid, & Schwenkmezger, 1997) to multiple constructs and multiple methods is presented. The model allows investigators to separate true change from measurement error and to analyze change simultaneously for different methods. The authors also show how Campbell and Fiske’s (1959) guidelines for analyzing convergent and discriminant validity can be applied to the measurement of latent change. The practical application of the multimethod change model is illustrated in a reanalysis of child depression and anxiety scores (N = 906 American children) that were assessed by self- a...

Gender-role attitudes and behavior across the transition to parenthood.

Developmental Psychology — Tue, 05 Jan 2010 16:14:34 +0100

On the basis of social structural theory and identity theory, the current study examined changes in gender-role attitudes and behavior across the first-time transition to parenthood and following the birth of a second child for experienced mothers and fathers. Data were analyzed from the ongoing longitudinal Wisconsin Study of Families and Work. Gender-role attitudes, work and family identity salience, and division of household labor were measured for 205 first-time and 198 experienced mothers and fathers across 4 time points from 5 months pregnant to 12 months postpartum. Multilevel latent growth curve analysis was used to analyze the data. In general, parents became more traditional in their gender-role attitudes and behavior following the birth of a child, women changed more than men, a...

Testing a series of causal propositions relating time in child care to children’s externalizing behavior.

Developmental Psychology — Tue, 05 Jan 2010 16:14:31 +0100

Prior research has documented associations between hours in child care and children’s externalizing behavior. A series of longitudinal analyses were conducted to address 5 propositions, each testing the hypothesis that child care hours causes externalizing behavior. Data from the National Institute of Child Health and Human Development Early Child Care Research Network (NICHD) Study of Early Child Care and Youth Development were used in this investigation because they include repeated measures of child care experiences, externalizing behavior, and family characteristics. There were 3 main findings. First, the evidence linking child care hours with externalizing behavior was equivocal in that results varied across model specifications. Second, the association between child care hours and ...

Inferring the outcome of an ongoing novel action at 13 months.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

Many studies have demonstrated that infants can attribute goals to observed actions, whether they are presented live by familiar agents or on a computer screen by abstract figures. However, because most, if not all, of these studies rely on the repeated action presentations typical of infant studies, it is not clear whether infants are simply recognizing the completed action as goal directed, or whether they can productively infer a not-yet-achieved outcome from an ongoing action. We investigated this question by presenting 13-month-old infants with a single animated chasing event. Infants looked longer at the outcome of this action when, given the opportunity, the chaser did not catch the chasee than when it did. Crucially, this result was dependent on whether the action could be construe...

Logging on, bouncing back: An experimental investigation of online communication following social exclusion.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

This study tested the hypothesis that online communication with an unknown peer facilitates recovery from the acute aversive effects of social exclusion and examined whether this benefit may be greater for adolescents compared with young adults. A total of 72 young adults (mean age = 18.4 years) and 51 adolescents (mean age = 12.5 years) were randomly assigned to undergo a standardized laboratory induction of social inclusion or exclusion, followed by 12 min of either communication with an unfamiliar other-sex peer or solitary computer game play. Compared with solitary game play, instant messaging with an unfamiliar peer facilitated greater replenishment of self-esteem and perceived relational value among previously excluded adolescents and young adults. Online communication also resulted ...

Word learning in children with autism spectrum disorders.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

Autism spectrum disorders (ASD) have been gaining attention, partly as an example of unusual developmental trajectories related to early neurobiological differences. The present investigation addressed the process of learning new words to explore mechanisms of language delay and impairment. The sample included 21 typically developing toddlers matched on expressive vocabulary with 21 young children with ASD. Two tasks were administered to teach children a new word and were supplemented by cognitive and diagnostic measures. In most analyses, there were no group differences in performance. Children with ASD did not consistently make mapping errors, even in word learning situations that required the use of social information. These findings indicate that some children with ASD, in developmenta...

A process analysis of the transmission of distress from interparental conflict to parenting: Adult relationship security as an explanatory mechanism.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

Toward advancing conceptualizations of the spillover hypothesis, this study examined the conditions and mechanisms underlying the transmission of distress from the interparental relationship to parenting difficulties over a 2-year period in a sample of 233 mothers (M = 35.0 years) and fathers (M = 36.8 years) of kindergarten children. Findings from autoregressive structural equation models indicated that parents’ gender moderated associations between interparental conflict and parental psychological control and insensitivity to children’s negative affect. Pathways between interparental conflict and parenting difficulties over the 2-year period were significant for fathers but not mothers. Analysis of insecurity and depressive symptoms as affective mechanisms of spillover revealed that ...

Nonshared environmental mediation of the association between deviant peer affiliation and adolescent externalizing behaviors over time: Results from a cross-lagged monozygotic twin differences design.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

It has been argued that peers are the most important agent of adolescent socialization and, more specifically, that this socialization process occurs at the child-specific (or nonshared environmental) level (J. R. Harris, 1998; R. Plomin & Asbury, 2005). The authors sought to empirically evaluate this nonshared environmental peer influence hypothesis by examining the association between externalizing behaviors and deviant peer affiliation in a sample of 454 pairs of monozygotic (genetically identical) twins, assessed at ages 14 and 17, within a cross-lagged twin differences design. Results argued against a causal nonshared environmental influence of peer affiliation on the development of externalizing behaviors and in favor of nonshared environmental “selection.” In particular, the twi...

Children’s representations of family relationships, peer information processing, and school adjustment.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

This study examined children’s peer information processing as an explanatory mechanism underlying the association between their insecure representations of interparental and parent–child relationships and school adjustment in a sample of 210 first graders. Consistent with emotional security theory (P. T. Davies & E. M. Cummings, 1994), results indicated that children’s insecure representations of the interparental relationship were indirectly related to their academic functioning through association with their negative information processing of stressful peer events. Insecure interparental relationships were specifically linked with negative peer information processing patterns that, in turn, predicted increases in child maladjustment over a 1-year period. These pathways remained rob...

Semantic meaning and pragmatic interpretation in 5-year-olds: Evidence from real-time spoken language comprehension.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

Recent research on children’s inferencing has found that although adults typically adopt the pragmatic interpretation of some (implying not all), 5- to 9-year-olds often prefer the semantic interpretation of the quantifier (meaning possibly all). Do these failures reflect a breakdown of pragmatic competence or the metalinguistic demands of prior tasks? In 3 experiments, the authors used the visual-world eye-tracking paradigm to elicit an implicit measure of adults’ and children’s abilities to generate scalar implicatures. Although adults’ eye-movements indicated that adults had interpreted some with the pragmatic inference, children’s looks suggested that children persistently interpreted some as compatible with all (Experiment 1). Nevertheless, both adults and children were able...

Reciprocity in parenting of adolescents within the context of marital negativity.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

The authors investigated the degree to which parents become more similar to each other over time in their childrearing behaviors. Mothers and fathers of 451 adolescents were assessed at 3 points in time, with 2-year lags between each assessment. Data on parent warmth, harshness, and monitoring were collected by parent self-report, adolescent report, and observer ratings of family interactions. After controlling for earlier levels of parenting, parent education, and adolescent deviancy, spouse’s parenting and marital negativity were significant predictors of later parenting. Marital negativity tended to be a stronger predictor of fathering than mothering. For fathers, associations between spouse’s parenting and later fathering were strongest in marriages characterized by low negativity....

Mothers’ and fathers’ personality and parenting: The mediating role of sense of competence.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

This prospective longitudinal study addressed 3 key questions regarding the processes of parenting in a large community sample of mothers (n = 589) and fathers (n = 518). First, the collective impact of parental Big Five personality dimensions on overreactive and warm parenting, assessed 6 years later by adolescents, was examined. Second, mediation of these associations by sense of competence in the parenting role was addressed. Third, it was explored to what extent associations were similar for mothers and fathers. Agreeableness and Extraversion were related to lower levels of overreactivity and higher levels of warmth. Sense of competence completely mediated relations between personality and overreactivity and partially mediated relations between personality and warmth. The associations ...

Experiences of discrimination among Chinese American adolescents and the consequences for socioemotional and academic development.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

This longitudinal study examined the influences of discrimination on socioemotional adjustment and academic performance for a sample of 444 Chinese American adolescents. Using autoregressive and cross-lagged techniques, the authors found that discrimination in early adolescence predicted depressive symptoms, alienation, school engagement, and grades in middle adolescence but that early socioemotional adjustment and academic performance did not predict later experiences of discrimination. Further, their investigation of whether earlier or contemporaneous experiences of discrimination influenced developmental outcomes in middle adolescence indicated differential effects, with contemporaneous experiences of discrimination affecting socioemotional adjustment, whereas earlier discrimination was...

Reconciling the self and morality: An empirical model of moral centrality development.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

This study advances the reconciliation model, which explains this anomaly within a developmental framework by positing that the relationship between the self’s interests and moral concerns ideally transforms from one of mutual competition to one of synergy. The degree to which morality is central to an individual’s identity—or moral centrality—was operationalized in terms of values advanced implicitly in self-understanding narratives; a measure was developed and then validated. Participants were 97 university students who responded to a self-understanding interview and to several measures of morally relevant behaviors. Results indicated that communal values (centered on concerns for others) positively predicted and agentic (self-interested) values negatively predicted moral behavio...

Trajectories of antisocial behavior and psychosocial maturity from adolescence to young adulthood.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

Most theorizing about desistance from antisocial behavior in late adolescence has emphasized the importance of individuals’ transition into adult roles. In contrast, little research has examined how psychological development in late adolescence and early adulthood contributes desistance. The present study examined trajectories of antisocial behavior among serious juvenile offenders from 14 through 22 years of age and tested how impulse control, suppression of aggression, future orientation, consideration of others, personal responsibility, and resistance to peer influence distinguished between youths who persisted in antisocial behavior and youths who desisted. Different patterns of development in psychosocial maturity from adolescence to early adulthood, especially with respect to impul...

Does the conceptual distinction between singular and plural sets depend on language?

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

Previous studies indicate that English-learning children acquire the distinction between singular and plural nouns between 22 and 24 months of age. Also, their use of the distinction is correlated with the capacity to distinguish nonlinguistically between singular and plural sets in a manual search paradigm (D. Barner, D. Thalwitz, J. Wood, S. Yang, & S. Carey, 2007). The authors used 3 experiments to explore the causal relation between these 2 capacities. Relative to English, Japanese and Mandarin had impoverished singular–plural marking. Using the manual search task, in Experiment 1 the authors found that by around 22 months of age, Japanese children also distinguished between singular and plural sets. Experiments 2 and 3 extended this finding to Mandarin-learning toddlers. Mandarin le...

Counting on working memory when learning to count and to add: A preschool study.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

In this study, the author aimed at measuring how much limited working memory capacity constrains early numerical development before any formal mathematics instruction. To that end, 4- and 5-year-old children were tested for their memory skills in the phonological loop (PL), visuo-spatial sketchpad (VSSP), and central executive (CE); they also completed a series of tasks tapping their addition and counting skills. A general vocabulary test was given to examine the difference between the children’s numerical and general vocabulary. The results indicated that measures of the PL and the CE, but not those of the VSSP, were correlated with children’s performance in counting, addition and general vocabulary. However, the predictive power of the CE capacity was significantly stronger than that...

Predictors of changes in weight esteem among mainland Chinese adolescents: A longitudinal analysis.

Developmental Psychology — Tue, 10 Nov 2009 16:53:03 +0100

Weight and body image concerns are prevalent among adolescents across cultures and pose significant threats to well-being, yet there is a paucity of longitudinal research on samples living in non-Western and developing countries. This prospective study assessed the extent to which select sociocultural, psychological, and biological risk factors contributed to changes in weight esteem among adolescent girls and boys living in the People’s Republic of China. Students (181 boys, 320 girls) from middle schools and high schools in Southwest China completed measures of demographics; weight esteem; thin female and lean, muscular male appearance ideals; positive and negative affect; and appearance-based social pressure, teasing, and comparison. Subsequently, weight esteem was reassessed 18 month...

Infants’ learning of novel words in a stochastic environment.

Developmental Psychology — Tue, 10 Nov 2009 16:53:02 +0100

In everyday word learning words are only sometimes heard in the presence of their referent, making the acquisition of novel words a particularly challenging task. The current study investigated whether children (18-month-olds who are novice word learners) can track the statistics of co-occurrence between words and objects to learn novel mappings in a stochastic environment. Infants were briefly trained on novel word–novel object pairs with variable degrees of co-occurrence: Words were either paired reliably with 1 referent or stochastically paired with 2 different referents with varying probabilities. Infants were sensitive to the co-occurrence statistics between words and referents, tracking not just the strongest available contingency but also low-frequency information. The statistical...

Memory and depressive symptoms are dynamically linked among married couples: Longitudinal evidence from the AHEAD study.

Developmental Psychology — Tue, 10 Nov 2009 16:53:02 +0100

This study examined dyadic interrelations between episodic memory and depressive symptom trajectories of change in old and advanced old age. The authors applied dynamic models to 10-year incomplete longitudinal data of initially 1,599 married couples from the study of Asset and Health Dynamics Among the Oldest Old (Mage = 75 years at Time 1). The authors found domain-specific lead–lag associations (time lags of 2 years) among wives and husbands as well as between spouses. For memory, better performance among husbands protected against subsequent memory decline among wives, with no evidence of a directed effect in the other direction. For depressive symptoms, wives’ scores predicted subsequent depression increase and memory decline among husbands. Possible individual covariates (age, ed...

Crossing the divide: Infants discriminate small from large numerosities.

Developmental Psychology — Tue, 10 Nov 2009 16:53:00 +0100

Although young infants have repeatedly demonstrated successful numerosity discrimination across large sets when the number of items in the sets changes twofold (E. M. Brannon, S. Abbott, & D. J. Lutz, 2004; J. N. Wood & E. S. Spelke, 2005; F. Xu & E. S. Spelke, 2000), they consistently fail to discriminate a twofold change in number when one set is large and the other is small ( (Source: Developmental Psychology)

The effect of a looker’s past reliability on infants’ reasoning about beliefs.

Developmental Psychology — Tue, 10 Nov 2009 16:52:58 +0100

We investigated whether 16-month-old infants’ past experience with a person’s gaze reliability influences their expectation about the person’s ability to form beliefs. Infants were first administered a search task in which they observed an experimenter show excitement while looking inside a box that either contained a toy (reliable looker condition) or was empty (unreliable looker condition). The infants were then administered a true belief task in which they watched as the same experimenter hid a toy in 1 of 2 locations. In the test trial, the infants witnessed the experimenter search for the toy in a location that was consistent or inconsistent with her belief about the toy’s location. Results for the true belief task indicated that only the infants in the reliable looker conditi...

Cue competition effects and young children’s causal and counterfactual inferences.

Developmental Psychology — Tue, 10 Nov 2009 16:52:58 +0100

The authors examined cue competition effects in young children using the blicket detector paradigm, in which objects are placed either singly or in pairs on a novel machine and children must judge which objects have the causal power to make the machine work. Cue competition effects were found in a 5- to 6-year-old group but not in a 4-year-old group. Equivalent levels of forward and backward blocking were found in the former group. Children’s counterfactual judgments were subsequently examined by asking whether or not the machine would have gone off in the absence of 1 of 2 objects that had been placed on it as a pair. Cue competition effects were demonstrated only in 5- to 6-year-olds using this mode of assessing causal reasoning. (PsycINFO Database Record (c) 2009 APA, all rights reser...

Do neighborhood and home contexts help explain why low-income children miss opportunities to participate in activities outside of school?

Developmental Psychology — Tue, 10 Nov 2009 16:52:58 +0100

In this study, children’s participation (N = 1,420) in activities outside of elementary school was examined as a function of disparities in family income using data from the Panel Study of Income Dynamics, Child Development Supplement. Children’s neighborhood and home environments were investigated as mechanisms linking income disparities and participation rates. Family income was positively associated with children’s participation in activities, with the largest effect sizes evident for children at the lowest end of the income distribution. Affluence in the neighborhood and cognitive stimulation in the home were both important mediators of the association between income and participation, explaining from approximately one tenth to one half of the estimated associations between incom...

Positive parenting in adolescence and its relation to low point narration and identity status in emerging adulthood: A longitudinal analysis.

Discussion centers on the potential impact of positive parenting as a contributor to healthy low point narration and identity in emerging adulthood. (PsycINFO Database Record (c) 2009 APA, all rights reserved) (Source: Developmental Psychology)

Affiliation with antisocial peers, susceptibility to peer influence, and antisocial behavior during the transition to adulthood.

Developmental Psychology — Tue, 10 Nov 2009 16:52:58 +0100

Developmental theories suggest that affiliation with deviant peers and susceptibility to peer influence are important contributors to adolescent delinquency, but it is unclear how these variables impact antisocial behavior during the transition to adulthood, a period when most delinquent individuals decline in antisocial behavior. Using data from a longitudinal study of 1,354 antisocial youth, the present study examined how individual variation in exposure to deviant peers and resistance to peer influence affect antisocial behavior from middle adolescence into young adulthood (ages 14 to 22 years). Whereas we find evidence that antisocial individuals choose to affiliate with deviant peers, and that affiliating with deviant peers is associated with an individual’s own delinquency, these c...

Parenting and antisocial behavior: A model of the relationship between adolescent self-disclosure, parental closeness, parental control, and adolescent antisocial behavior.

Developmental Psychology — Tue, 10 Nov 2009 16:52:58 +0100

This study used data collected from a sample of 840 Italian adolescents (418 boys; M age = 12.58) and their parents (657 mothers; M age = 43.78) to explore the relations between parenting, adolescent self-disclosure, and antisocial behavior. In the hypothesized model, parenting practices (e.g., parental monitoring and control) have direct effects on parental knowledge and antisocial behavior. Parenting style (e.g., parent–child closeness), on the other hand, is directly related to adolescent self-disclosure, which in turn is positively related to parental knowledge and negatively related to adolescents’ antisocial behavior. A structural equation model, which incorporated data from parents and adolescents, largely supported the hypothesized model. Gender-specific models also found some ...

The role of ethnicity in observers’ ratings of mother–child behavior.

Developmental Psychology — Tue, 10 Nov 2009 16:52:58 +0100

This study examined the role of ethnicity in untrained observers’ ratings of videotaped mother–child interactions. Participants were Black, White, and Latino undergraduates (N = 109), who rated videotapes of 4 Black, 4 White, and 4 Latino mother–child dyads. Overall, participants of different ethnicities showed more similarities than differences in their ratings of parent–child behavior. There was, however, evidence that participant ethnicity and parent–child ethnicity interacted for ratings of child defiance/negative emotion. Black and White participants differed in their ratings of Black and White children’s defiance/negative emotion, with members of each ethnic group favoring children of their own ethnic group. Intergroup contact appeared to play a role in ratings of parent ...

A longitudinal study of children’s performance on simple multiplication and division problems.

Developmental Psychology — Tue, 25 Aug 2009 14:02:27 +0100

The authors investigated the performance on simple multiplication and division problems of 8-year-old children longitudinally to determine the developmental trajectories of both operations. Twice a year, during 2 consecutive school years, children performed a multiplication and division verification task and a number-matching task. All effects that were observed in multiplication performance (problem size, 5, and tie effect and Tie × Size interaction) were also observed in division performance. The developmental trajectories of these effects are described. The authors observed strong developmental parallels between both operations. These results are in line with strongly interconnected memory networks for multiplication and division facts, at least in young children. The results of the nu...

Shifting development in mid-childhood: The influence of between-task interference.

Developmental Psychology — Tue, 25 Aug 2009 14:02:27 +0100

Performance on the task-switching paradigm is greatly affected by the amount of conflict between tasks. Compared to adults, children appear to be particularly influenced by this conflict, and this suggests that the ability to resolve interference between tasks improves with age. The authors used the task-switching paradigm to investigate how this ability develops in mid-childhood. Experiment 1 compared the ability of 5- to 8-year-olds and of 9- to 11-year-olds to switch between decisions about the color and shape of an object. The 5- to 8-year-olds were slower to switch task and experienced more interference from the irrelevant task than did the 9- to 11-year-olds, which suggests a developmental improvement in resolving conflict between tasks during mid-childhood. In Experiment 2, the infl...

Developmental implications of openness to experience in preschool children: Gender differences in young adulthood.

Developmental Psychology — Tue, 25 Aug 2009 14:02:27 +0100

This study examined the longitudinal implications in late adolescence and emerging adulthood of Openness to Experience measured in preschool in a sample of 102 participants who were followed from preschool through emerging adulthood (age 23). Although gender differences in mean Openness scores were not found, the postpubertal longitudinal correlations associated with preschool Openness differed markedly for the sexes. Preschool boys who received high Openness scores were consistently described, both by self and others, as resilient, competent, and self-assured in young adulthood. In contrast, female participants who received high Openness scores continued to be seen as open at ages 18 and 23 but were also viewed, both by self and others, as more psychologically vulnerable than were their m...

Relational victimization predicts children’s social-cognitive and self-regulatory responses in a challenging peer context.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

In this study, the authors examined whether exposure to relational victimization was associated with children’s thoughts, emotions, and behavior in an unfamiliar, challenging peer context. Children (110 girls, 96 boys; mean age = 10.13 years, SD = 1.16) reported on their exposure to relational victimization by peers. Following a challenging interaction with an unfamiliar peer, children reported on their beliefs about their interaction partners and their social goals (i.e., focus on getting to know their partner vs. impressing their partner) during the interaction. Coders rated children’s emotion and behavior regulation and the quality of the dyadic context. Results from hierarchical linear modeling analyses reveal that relational victimization predicted maladaptive social-cognitive pro...

Young children’s understanding of joint commitments.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

When adults make a joint commitment to act together, they feel an obligation to their partner. In 2 studies, the authors investigated whether young children also understand joint commitments to act together. In the first study, when an adult orchestrated with the child a joint commitment to play a game together and then broke off from their joint activity, 3-year-olds (n = 24) reacted to the break significantly more often (e.g., by trying to re-engage her or waiting for her to restart playing) than when she simply joined the child’s individual activity unbidden. Two-year-olds (n = 24) did not differentiate between these 2 situations. In the second study, 3- and 4-year-old children (n = 30 at each age) were enticed away from their activity with an adult. Children acknowledged their leavin...

Patterns of home leaving and subjective well-being in emerging adulthood: The role of motivational processes and parental autonomy support.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

In this study, the authors aimed to examine how emerging adults’ living arrangements—and the motives underlying those arrangements, as conceptualized in self-determination theory—relate to subjective well-being. A Belgian sample of 224 emerging adults and their parents completed self-report questionnaires. Analyses that used structural equation modeling showed that autonomous motivation for one’s living arrangement is more strongly related to emerging adults’ well-being than the living arrangement per se. Further, autonomy-supportive parenting was found to relate positively to an autonomously regulated residential status. Implications for the meaning and development of autonomy during emerging adulthood are discussed. (PsycINFO Database Record (c) 2009 APA, all rights reserved) (...

Daily family conflict and emotional distress among adolescents from Latin American, Asian, and European backgrounds.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

The authors employed a daily diary method to assess daily frequencies of interparental and parent–adolescent conflict over a 2-week period and their implications for emotional distress across the high school years in a longitudinal sample of 415 adolescents from Latin American, Asian, and European backgrounds. Although family conflict remained fairly infrequent among all ethnic backgrounds across the high school years, its impact on emotional distress was significant across ethnicity and gender. In addition, parent–adolescent conflict significantly mediated the association between interparental conflict and emotional distress. These associations were observed at both the individual and the daily levels, providing evidence for both the chronic and episodic implications of family conflic...

Pathways to paternal engagement: Longitudinal effects of risk and resilience on nonresident fathers.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

This article assesses the longitudinal effects of risk and resilience on unmarried nonresident fathers’ engagement with children across the first 3 years of their lives. The authors used a subsample of 549 men from the Fragile Families and Child Wellbeing Study who were unmarried and noncohabiting at the time of the child’s birth. They found not only that risk and resilience factors had a direct effect on paternal engagement but also that their association with engagement was mediated by fathers’ continued nonresidence and mother–father relationship quality. Men who leave trajectories of high risk behind during the transition to fatherhood and who have a trajectory characterized by resilience factors are more likely to experience better relationships with the mother of their childr...

Developmental context effects on bicultural posttrauma self repair in chimpanzees.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

Longitudinal studies have shown how early developmental contexts contribute significantly to self-development; their influence extends through adulthood, informs sociality, and affects resilience under severe stress. While the importance of sociality in trauma recovery is recognized, the relationship between developmental and posttrauma contexts and recovery effects is less appreciated, particularly in cases in which recovery contexts differ widely from the culture of origin. Using an attachment-based model of bicultural (competence in two cultures) development, the authors examined the role of self in posttrauma repair of chimpanzees (Pan troglodytes) who had been differentially reared by humans during neuroethologically formative periods and subsequently used as biomedical subjects. Resu...

Here we go again: A dynamic systems perspective on emotional rigidity across parent–adolescent conflicts.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

The authors used a dynamic systems theoretical approach to examine intraindividual variability in emotional responses during the transitional period of adolescence. Longitudinal diary data were collected regarding conflicts between 17 teenage girls and their mothers over a period of a year. The results revealed a reversed u-shaped relation between girls’ emotional variability and the number of conflicts. Moreover, girls who showed limited variability in emotional states across conflict episodes tended to attach the same emotional state to divergent conflict topics. Explained as the result of a self-organizing process, emotional rigidity (i.e., a lack of variability and contextual sensitivity) possibly undermines the adaptive potential of the parent–adolescent system in times of relatio...

Age differences in personality: Evidence from a nationally representative Australian sample.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

Cross-sectional age differences in the Big Five personality traits were examined in a nationally representative sample of Australians (N = 12,618; age range = 15–84). Extraversion, Neuroticism, and Openness were negatively associated with age, whereas Agreeableness and Conscientiousness were positively associated with age. Effect sizes comparing the youngest and the oldest sample members were usually medium to large in size. Item-level analysis revealed that although most personality descriptors showed patterns similar to those exhibited by their respective global traits, this was not always the case. Thus, investigations of narrower aspects of personality may reveal more nuanced age differences and may begin to explain contradictory results from different studies. (PsycINFO Database Rec...

Recognition of facial expressions of mixed emotions in school-age children exposed to terrorism.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

This exploratory study aims at investigating the effects of terrorism on children’s ability to recognize emotions. A sample of 101 exposed and 102 nonexposed children (mean age = 11 years), balanced for age and gender, were assessed 20 months after a terrorist attack in Beslan, Russia. Two trials controlled for children’s ability to match a facial emotional stimulus with an emotional label and their ability to match an emotional label with an emotional context. The experimental trial evaluated the relation between exposure to terrorism and children’s free labeling of mixed emotion facial stimuli created by morphing between 2 prototypical emotions. Repeated measures analyses of covariance revealed that exposed children correctly recognized pure emotions. Four log-linear models were pe...

Psychosocial development from college through midlife: A 34-year sequential study.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

Two cohorts of alumni, leading-edge and trailing-edge baby boomers, first tested in their college years, were followed to ages 43 (N = 136) and 54 (N = 182) on a measure of Erikson’s theory of psychosocial development. Hierarchical linear modeling was used to model the trajectory of growth for each psychosocial issue across middle adulthood. As predicted, the early psychosocial issues (trust, autonomy, and initiative) showed patterns of slow and steady increases in favorable resolution, as did the midlife issue of generativity. Industry, found in earlier investigations on the samples to change to differing degrees by cohort, continued to show cohort differences through midlife. The quadratic terms indicated that growth was curvilinear for both cohorts on identity and intimacy, and ego in...

Developmental links of adolescent disclosure, parental solicitation, and control with delinquency: Moderation by parental support.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

This 4-wave study among 309 Dutch adolescents and their parents examined changes in adolescent disclosure, parental solicitation, and parental control and their links with the development of delinquent activities. Annually, adolescents and both parents reported on adolescent disclosure, parental solicitation, and parental control, and adolescents reported on delinquent activities and parental support. Latent growth curve analyses revealed a linear decline in parental control between ages 13 and 16. Adolescent disclosure decreased gradually in adolescent reports and showed an L-shaped pattern in father reports and a V-shaped pattern in mother reports. A stronger increase in delinquent activities was related to a stronger decrease in disclosure in mother and adolescent reports and to lower l...

Assessing differential effects: Applying regression mixture models to identify variations in the influence of family resources on academic achievement.

Developmental Psychology — Tue, 25 Aug 2009 14:02:26 +0100

Developmental scientists frequently seek to understand effects of environmental contexts on development. Traditional analytic strategies assume similar environmental effects for all children, sometimes exploring possible moderating influences or exceptions (e.g., outliers) as a secondary step. These strategies are poorly matched to ecological models of human development that posit complex individual by environment interactions. An alternative conceptual framework is proposed that tests the hypothesis that the environment has differential (nonuniform) effects on children. A demonstration of the utility of this framework is provided by examining the effects of family resources on children’s academic outcomes in a multisite study (N = 6,305). Three distinctive groups of children were identi...

Children’s context inappropriate anger and salivary cortisol.

Developmental Psychology — Tue, 25 Aug 2009 14:02:25 +0100

Some children show emotion that is not consistent with normative appraisal of the context and can therefore be defined as context inappropriate (CI). The authors used individual growth curve modeling and hierarchical multiple regression analyses to examine whether CI anger predicts differences in hypothalamic-pituitary-adrenal axis activity, as manifest in salivary cortisol measures. About 23% of the 360 children (ages 6–10 years, primarily 7–8) showed at least 1 expression of CI anger in situations designed to elicit positive affect. Expression of anger across 2 positive assessments was less common (around 4%). CI anger predicted the hypothesized lower levels of cortisol beyond that attributed to context appropriate anger. Boys’ CI anger predicted lower morning cortisol and flatter ...

The intergenerational transmission of parenting: Closing comments for the special section.

Developmental Psychology — Tue, 25 Aug 2009 14:02:25 +0100

The 5 studies in this special section both confirm prior findings regarding the intergenerational transmission of parenting and provide important new evidence regarding the intergenerational transmission of positive parenting and the developmental mediators that seem involved in that transmission. Consistent with earlier research, the findings suggest that harsh parenting in the 1st generation (G1) predicts similar behavior in the 2nd generation (G2) primarily through the exacerbation of G2 conduct problems. In contrast, replicated findings in this set of articles indicate that intergenerational continuities in positive parenting likely stem from the social and academic competencies such parenting engenders in the next generation. In addition, these 5 studies demonstrate that the evidence ...

A prospective three generational study of fathers’ constructive parenting: Influences from family of origin, adolescent adjustment, and offspring temperament.

Developmental Psychology — Tue, 25 Aug 2009 14:02:25 +0100

This prospective, intergenerational study considered multiple influences on 102 fathers’ constructive parenting of 181 children. Fathers in the 2nd generation (G2) were recruited as boys on the basis of neighborhood risk for delinquency and assessed through early adulthood. The fathers’ parents (G1) and the G2 mothers of G3 also participated. A multiagent, multimethod approach was used to measure G1 and G2 constructive parenting (monitoring, discipline, warmth, and involvement), G2 positive adolescent adjustment, and problem behavior in all 3 generations, including G3 difficult temperament and externalizing problems in early and middle childhood, respectively. Path modeling supported direct transmission of G1 constructive parenting of G2 in late childhood to G2 constructive parenting o...

Intergenerational continuity in parenting behavior: Mediating pathways and child effects.

Developmental Psychology — Tue, 25 Aug 2009 14:02:25 +0100

This prospective, longitudinal investigation examined mechanisms proposed to explain continuities in parenting behavior across 2 generations (G1, G2). Data came from 187 G2 adults, their mothers (G1), and their children (G3). Prospective information regarding G2 was collected both during adolescence and early adulthood. G1 data were collected during G2’s adolescence, and G3 data were generated during the preschool years. Assessments included both observational and self-report measures. The results indicated a direct relationship between G1 and G2 harsh parenting, and between G1 and G2 positive parenting. As predicted, specific mediators accounted for intergenerational continuity in particular types of parenting behavior. G2 externalizing behavior mediated the relationship between G1 and ...

Intergenerational continuity in parenting quality: The mediating role of social competence.

Developmental Psychology — Tue, 25 Aug 2009 14:02:25 +0100

This study examined social competence as a mediator in the pathway from 1st generation (G1) to 2nd generation (G2) parenting quality. A normative sample of children and their parents were assessed in childhood, and again 10 and 20 years later. Parenting quality of G1 parents was assessed at each time point with multiple informants, as was G2 social competence. G2 parenting was assessed at the 20-year follow-up for those who were parents. The mediational role of social competence in G1 to G2 parenting quality was tested via nested path analytic models, accounting for continuity and cross-domain relations. Social competence mediated the intergenerational relation of parenting quality; results were invariant across gender and ethnic minority status and were unchanged after controlling for age...

Parenting practices and problem behavior across three generations: Monitoring, harsh discipline, and drug use in the intergenerational transmission of externalizing behavior.

Developmental Psychology — Tue, 25 Aug 2009 14:02:25 +0100

Using data from grandparents (G1), parents (G2), and children (G3), this study examined continuity in parental monitoring, harsh discipline, and child externalizing behavior across generations, and the contribution of parenting practices and parental drug use to intergenerational continuity in child externalizing behavior. Structural equation and path modeling of prospective, longitudinal data from 808 G2 participants, their G1 parents, and their school-age G3 children (n = 136) showed that parental monitoring and harsh discipline demonstrated continuity from G1 to G2. Externalizing behavior demonstrated continuity from G2 to G3. Continuity in parenting practices did not explain the intergenerational continuity in externalizing behavior. Rather, G2 adolescent externalizing behavior predict...

The intergenerational continuity of observed early parenting: A prospective, longitudinal study.

Developmental Psychology — Tue, 25 Aug 2009 14:02:25 +0100

The authors report the results from a prospective, longitudinal study of cross-generational parenting quality in a lower socioeconomic status sample of moderate ethnic diversity (N = 61). The study extends previous research on intergenerational continuity of parenting in several significant ways: (a) Assessments in both generations were based on direct observation, (b) assessments were made at the same age (24 months) in both generations, (c) there were controls for later parenting in the first generation, and (d) there were controls for critical background factors (stress, socioeconomic status, child and parent IQ). An observed parenting-quality composite showed moderate stability (r = .43) across generations, and findings held after controlling for all other factors. A possible special r...

The intergenerational transmission of parenting: Introduction to the special section.

Developmental Psychology — Tue, 25 Aug 2009 14:02:25 +0100

Long-standing interest in the intergenerational transmission of parenting has stimulated work focused on child maltreatment, harsh parenting, and warm–supportive rearing. In addition to documenting significant, even if modest, continuity in parenting across generations, research in this area has addressed questions of mediation and moderation. This special section extends work in this general area, with 2 studies further chronicling intergenerational transmission and 3 further illuminating mechanisms through which parenting in 1 generation is repeated in a subsequent generation. Lacking, however, is high-quality work highlighting the conditions under which parenting is not transmitted across generations.

Use of missing data methods in longitudinal studies: The persistence of bad practices in developmental psychology.

Developmental Psychology — Thu, 09 Jul 2009 12:18:06 +0100

Developmental science rests on describing, explaining, and optimizing intraindividual changes and, hence, empirically requires longitudinal research. Problems of missing data arise in most longitudinal studies, thus creating challenges for interpreting the substance and structure of intraindividual change. Using a sample of reports of longitudinal studies obtained from three flagship developmental journals—Child Development, Developmental Psychology, and Journal of Research on Adolescence—we examined the number of longitudinal studies reporting missing data and the missing data techniques used. Of the 100 longitudinal studies sampled, 57 either reported having missing data or had discrepancies in sample sizes reported for different analyses. The majority of these studies (82%) used mis...

Action type and goal type modulate goal-directed gaze shifts in 14-month-old infants.

Developmental Psychology — Thu, 09 Jul 2009 12:18:06 +0100

Ten- and 14-month-old infants’ gaze was recorded as the infants observed videos of different hand actions directed toward multiple goals. Infants observed an actor who (a) reached for objects and displaced them, (b) reached for objects and placed them inside containers, or (c) moved his fisted hand. Fourteen-month-olds, but not 10-month-olds, anticipated the goal of reaching actions but tracked all the other actions reactively. Fourteen-month-olds also produced more anticipatory gaze shifts during containment compared with displacement and differentiated between reaching actions dependent on whether the overall goal was to displace objects or place objects inside containers. These results demonstrate that action type and goal type modulate the latency of goal-directed gaze shifts in infa...

Daily family assistance and the psychological well-being of adolescents from Latin American, Asian, and European backgrounds.

Developmental Psychology — Thu, 09 Jul 2009 12:18:06 +0100

The daily diary method was used to examine the implications of adolescents’ daily assistance behaviors for both positive and negative aspects of psychological well-being among an ethnically diverse sample of 752 adolescents of ages 14 to 15 years. Results indicated that, contrary to the expectations of some observers, providing daily assistance to the family generally was not stressful for adolescents. Rather, assisting the family was associated with higher levels of happiness due, in large part, to the sense of role fulfillment it provided the adolescents. Few individual or group differences were observed in the association between family assistance and psychological well-being. These results suggest that family assistance serves as a meaningful activity in adolescents’ lives by creat...

Aggressive versus nonaggressive antisocial behavior: Distinctive etiological moderation by age.

Developmental Psychology — Thu, 09 Jul 2009 12:18:06 +0100

Research has supported the existence of distinct behavioral patterns, demographic correlates, and etiologic mechanisms for aggressive (AGG) versus nonaggressive but delinquent (DEL) antisocial behavior. Though behavioral genetic studies have the potential to further crystallize these dimensions, inconsistent results have limited their contribution. These inconsistencies may stem in part from the limited attention paid to the impact of age. In the current study, the authors thus examined age-related etiological moderation of AGG and DEL antisocial behavior in a sample of 720 sibling pairs (ranging in age from 10 to 18 years) with varying degrees of genetic relatedness. Results reveal that the magnitude of genetic and environmental influences on AGG remained stable across adolescence. By con...

Do gender differences in help avoidance vary by ethnicity? An examination of African American and European American students during early adolescence.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

The present research examined whether the nature of gender differences varies by race for two types of academic engagement in the classroom (help avoidance and voice with the teacher) in a sample of early adolescents (N = 456; 55% female, 60% African American and 40% European American) making the transition to middle school. Growth curve analyses indicated that help avoidance increased over time, voice remained stable, and achievement declined. In line with hypotheses based on cultural variations in the female role, there were no gender differences in help avoidance for African American students, whereas for European American students, girls were lower in help avoidance than were boys. For African American students, there were no gender differences in voice with the teacher, whereas for Eu...

Infants’ intermodal perception of canine (Canis familairis) facial expressions and vocalizations.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

From birth, human infants are able to perceive a wide range of intersensory relationships. The current experiment examined whether infants between 6 months and 24 months old perceive the intermodal relationship between aggressive and nonaggressive canine vocalizations (i.e., barks) and appropriate canine facial expressions. Infants simultaneously viewed static aggressive and nonaggressive expressions of the same canine and heard an aggressive or nonaggressive bark. Results indicate that 6-month-olds perceived the intermodal relationship for aggressive and nonaggressive barks and the appropriate expression. Results also revealed that in older but not younger infants, the initial or first looks were directed toward the appropriate expression and that older infants also looked proportionately...

The emotional and academic consequences of parental conditional regard: Comparing conditional positive regard, conditional negative regard, and autonomy support as parenting practices.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

The authors conducted 2 studies of 9th-grade Israeli adolescents (169 in Study 1, 156 in Study 2) to compare the parenting practices of conditional positive regard, conditional negative regard, and autonomy support using data from multiple reporters. Two socialization domains were studied: emotion control and academics. Results were consistent with the self-determination theory model of internalization, which posits that (a) conditional negative regard predicts feelings of resentment toward parents, which then predict dysregulation of negative emotions and academic disengagement; (b) conditional positive regard predicts feelings of internal compulsion, which then predict suppressive regulation of negative emotions and grade-focused academic engagement; and (c) autonomy support predicts sen...

Differentiation of cognitive abilities across the life span.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

Existing representations of cognitive ability structure are exclusively based on linear patterns of interrelations. However, a number of developmental and cognitive theories predict that abilities are differentially related across ages (age differentiation–dedifferentiation) and across levels of functioning (ability differentiation). Nonlinear factor analytic models were applied to multivariate cognitive ability data from 6,273 individuals, ages 4 to 101 years, who were selected to be nationally representative of the U.S. population. Results consistently supported ability differentiation but were less clear with respect to age differentiation–dedifferentiation. Little evidence for age modification of ability differentiation was found. These findings are particularly informative about t...

Anxious solitude and peer exclusion predict social helplessness, upset affect, and vagal regulation in response to behavioral rejection by a friend.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

It was hypothesized that combined individual child vulnerability (anxious solitude) and interpersonal stress (peer exclusion) would predict the strongest responses to experimentally manipulated behavioral peer rejection. Results indicated that in a sample of 3rd graders (N = 160, 59% girls), anxious solitary excluded children displayed more behavioral manifestations of social helplessness before and after behavioral rejection, reported more feelings of rejection in anticipation of and reaction to behavioral rejection, and were observably more upset during behavioral rejection than were normative children. Moreover, affective responses to behavioral rejection mediated the relation between anxious solitary excluded status and behavioral manifestations of social helplessness. Furthermore, anx...

Family–school connections and the transitions of low-income youths and english language learners from middle school to high school.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

The theoretical and policy focus on parental involvement in education has evolved into a consideration of 2-way connections between families and schools. Working from a social capital perspective emphasizing the importance of information in periods and domains of uncertainty, the author tested a specific application of this reconceptualization in this study. Multilevel models of the National Education Longitudinal Study (n = 17,899) revealed that youths started high school in higher level math when parents, middle school personnel, and high school personnel were in contact with each other and when middle school personnel bridged middle school and high school. The observed effects of other family–school patterns on math and of all family–school patterns on science were driven by selecti...

Predictors and pathways from infancy to symptoms of anxiety and depression in early adolescence.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

Data from a prospective 11-year longitudinal survey were used to identify early predictors and pathways to symptoms of anxiety and depression at 12–13 years of age, and to examine whether there were unique predictors of anxious versus depressive symptoms. Structural equation modeling was used to explore longitudinal relations between contextual (maternal distress, family adversities, and social support) and temperamental (shyness and emotionality) risk factors in their prediction of informant-consistent symptoms of anxiety and depression. The results show that early risk factors can explain 38% of the variance in boys’ covarying symptoms of anxiety and depression in early adolescence, and 25% of variance in girls’ covarying symptoms. Two main pathways were identified. One pathway was...

Developmental and individual differences in young children’s use and maintenance of a selective memory strategy.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

Children who were 4 to 8 years of age were asked to perform a sort-recall task where only half of the items had to be studied and remembered. Following a baseline trial, children were assigned to 1 of 3 groups and were prompted to use either a sorting or a clustering strategy (experimental groups) or were not prompted at all (control group). Children were seen 2 weeks later and given a new set of items for the transfer-of-training sort–recall phases. Levels of recall and strategy use (sorting, clustering, multiple strategy use) were higher for older children, typical items, sorting prompts, and trials with repeated presentations of test materials. Older children used more strategies than younger children, although even 4-year-olds used more than one strategy when performing the memory ta...

Depressive symptoms in mothers and children: Preschool attachment as a moderator of risk.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

Drawing from transactional models, the authors examined whether attachment security measured at age 3 (a potential source of differential vulnerability) interacts with the course of maternal depressive symptoms over an 8-year period (a potential source of differential exposure) in predicting children’s self-reported depressive symptoms at age 11. Participants were from the NICHD Study of Early Child Care (N = 938). Results from growth curve modeling and analysis of covariance suggest that preschool attachment quality moderates the influence of subsequent maternal depression on children. In particular, variability in the course of maternal depressive symptoms predicted offspring depressive symptoms only among those children with an insecure attachment history. A potential protective effec...

Aggressive behavior between siblings and the development of externalizing problems: Evidence from a genetically sensitive study.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

This study investigated the prospective links between sibling aggression and the development of externalizing problems using a multilevel modeling approach with a genetically sensitive design. The sample consisted of 780 adolescents (390 sibling pairs) who participated in 2 waves of the Nonshared Environment in Adolescent Development project. Sibling pairs with varying degree of genetic relatedness, including monozygotic twins, dizygotic twins, full siblings, half siblings, and genetically unrelated siblings, were included. The results showed that sibling aggression at Time 1 was significantly associated with the focal child’s externalizing problems at Time 2 after accounting for the intraclass correlations between siblings. Sibling aggression remained significant in predicting subsequen...

Longitudinal relations of children’s effortful control, impulsivity, and negative emotionality to their externalizing, internalizing, and co-occurring behavior problems.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

The purpose of the study was to examine the relations of effortful control (EC), impulsivity, and negative emotionality to at least borderline clinical levels of symptoms and change in maladjustment over four years. Children’s (N = 214; 77% European American; M age = 73 months) externalizing and internalizing symptoms were rated by parents and teachers at 3 times, 2 years apart (T1, T2, and T3) and were related to children’s adult-rated EC, impulsivity, and emotion. In addition, the authors found patterns of change in maladjustment were related to these variables at T3 while controlling for the T1 predictor. Externalizing problems (pure or co-occurring with internalizing problems) were associated with low EC, high impulsivity, and negative emotionality, especially anger, and patterns o...

School performance and genetic and environmental variance in antisocial behavior at the transition from adolescence to adulthood.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

Antisocial behavior increases in adolescence, particularly among those who perform poorly in school. As adolescents move into adulthood, both educational attainment and the extent to which antisocial behavior continues have implications for adolescents’ abilities to take on constructive social roles. The authors used a population-representative longitudinal twin study to explore how links among genetic and environmental influences at ages 17 and 24 may be implicated in the developmental processes involved. At age 17, expression of both genetic and nonshared environmental vulnerabilities unique to antisocial behavior was greater among those with low GPA than among those with higher GPA. This suggested that maintenance of high GPA buffered the impact of both genetic and environmental influ...

The contribution of children’s self-regulation and classroom quality to children’s adaptive behaviors in the kindergarten classroom.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

In this study, the authors examined the extent to which children’s self-regulation upon kindergarten entrance and classroom quality in kindergarten contributed to children’s adaptive classroom behavior. Children’s self-regulation was assessed using a direct assessment upon entrance into kindergarten. Classroom quality was measured on the basis of multiple classroom observations during the kindergarten year. Children’s adaptive classroom behavior in kindergarten was assessed through teacher report and classroom observations: Teachers rated children’s cognitive and behavioral self-control and work habits during the spring of the kindergarten year; observers rated children’s engagement and measured off-task behavior at 2-month intervals from November to May. Hierarchical linear mo...

The protective effects of neighborhood collective efficacy on British children growing up in deprivation: A developmental analysis.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

This article reports on the influence of neighborhood-level deprivation and collective efficacy on children’s antisocial behavior between the ages of 5 and 10 years. Latent growth curve modeling was applied to characterize the developmental course of antisocial behavior among children in the E-Risk Longitudinal Twin Study, an epidemiological cohort of 2,232 children. Children in deprived versus affluent neighborhoods had higher levels of antisocial behavior at school entry (24.1 vs. 20.5, p < .001) and a slower rate of decline from involvement in antisocial behavior between the ages of 5 and 10 (-0.54 vs. -0.78, p < .01). Neighborhood collective efficacy was negatively associated with levels of antisocial behavior at school entry (r = -.10, p < .01) but only in deprived neighborhoods; th...

It takes two to tango: How parents’ and adolescents’ personalities link to the quality of their mutual relationship.

Developmental Psychology — Thu, 09 Jul 2009 12:18:05 +0100

According to J. Belsky’s (1984) process model of parenting, both adolescents’ and parents’ personality should exert a significant impact on the quality of their mutual relationship. Using multi-informant, symmetric data on the Big Five personality traits and the relationship quality of mothers, fathers, and two adolescent children, the current study set out to test this prediction. Adolescents’ agreeableness and parents’ extraversion emerged as predictors of relationship warmth, whereas parents’ openness emerged as a predictor of low restrictive control. In addition, some gender-specific effects emerged. Overall, parents’ and adolescents’ traits equally predicted the amount of relationship warmth, whereas adolescents’ unique personality more strongly predicted the amount ...

Habitual size and projective size: The logic of spatial systems in children’s drawings.

Developmental Psychology — Thu, 09 Jul 2009 12:18:04 +0100

The current study analyzed figure size modification in different types of spatial context (C. Lange-Küttner, 1997, Lange-Küttner, 2004) for sequence and practice effects. Children of 7, 9, and 11 years of age, as well as 17-year-olds, drew figures in a series of ready-made spatial axes systems, which (a) logically increased in dimensional complexity as in child development, (b) were randomized in sequence, or (c) were absent, as a control condition for figure size reduction through practice. Already 7-year-olds could subtly adapt figure size in the logical sequence, but the amount of size reduction stayed within the same size range as in the other two conditions. Only at 9 years of age did children show sensitivity to spatial constraints, with smaller figures in both the logical and rand...

Infancy parenting and externalizing psychopathology from childhood through adulthood: Developmental trends.

Developmental Psychology — Thu, 09 Jul 2009 12:18:04 +0100

Developmental models and previous findings suggest that early parenting is more strongly associated with externalizing problems in early childhood than it is in adolescence. In this article, the authors address whether the association of poor-quality infancy parenting and externalizing problems “rebounds” in adulthood. Poor-quality infancy parenting was associated with externalizing problems at kindergarten and first grade (mother report) as well as at 23 and 26 years (self report). Infancy parenting was not significantly associated with either mothers’ or youths’ reports of externalizing problems at 16 years. These findings are consistent with the notion that poor-quality infancy parenting is a risk factor for externalizing problems in developmental periods for which externalizing...

Troubled meditations on psychosexual differentiation: Reply to Hegarty (2009).

Developmental Psychology — Thu, 09 Jul 2009 12:18:04 +0100

P. Hegarty (see record 2009-09998-015) offered several critiques of the articles by G. Rieger, J. A. W. Linsenmeier, L. Gygax, and J. M. Bailey (see record 2007-19851-006) and K. D. Drummond, S. J. Bradley, M. Peterson-Badali, and K. J. Zucker (see record 2007-19851-005) that were published in a Developmental Psychology special section entitled “Sexual Orientation Across the Lifespan,” guest-edited by C. J. Patterson and R. C. Savin-Williams (2008): (a) reliance on a “disease paradigm” (i.e., the use of “medicalizing” language) of lesbian–gay–bisexual–transgender issues at the expense of a “stigma paradigm,” (b) endorsement of a developmental linkage between childhood sex-typed behavior and later gender identity–sexual orientation, and (c) various sociophilosophical...

Childhood gender noncomformity remains a robust and neutral correlate of sexual orientation: Reply to Hegarty (2009).

Developmental Psychology — Thu, 09 Jul 2009 12:18:04 +0100

In this issue, P. Hegarty (see record 2009-09998-015) comments on an article by G. Rieger, J. A. W. Linsenmeier, L. Gygax, and J. M. Bailey (see record 2007-19851-006) that compared videos of homosexual and heterosexual people from childhood and adulthood. The current authors claim it is reasonable to treat masculinity–femininity as a bipolar scale and present justification for the approach used in the earlier study. Measures used by Rieger et al. (2008) yielded large differences between homosexual and heterosexual participants, and these differences are likely to be more meaningful than the low and nonsignificant within-group correlations on which Hegarty chose to focus. The authors address his suggestion that they are working within a paradigm detrimental to the well-being of homosexua...

Toward an LGBT-informed paradigm for children who break gender norms: Comment on Drummond et al. (2008) and Rieger et al. (2008).

Developmental Psychology — Thu, 09 Jul 2009 12:18:04 +0100

In this commentary, the author reviews methodological and conceptual shortcomings of recent articles by K. D. Drummond, S. J. Bradley, M. Peterson-Badali, and K. J. Zucker (see record 2007-19851-005) as well as G. Rieger, J. A. W. Linsenmeier, L. Gygax, and J. M. Bailey (see record 2007-19851-006), which sought to predict adult sexual identity from childhood gender identity. The author argues that such research needs to incorporate a greater awareness of how stigmatization affects identity processes. Multidimensional models of gender identity that describe variation in children’s responses to pressure to conform to gender norms are particularly useful in this regard (S. K. Egan & D. G. Perry, 2001). Experiments on the interpretation of developmental data are reviewed to evidence how cult...

Adults’ autonomic and subjective emotional responses to infant vocalizations: The role of secure base script knowledge.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

This article examines the extent to which secure base script knowledge—as reflected in an adult’s ability to generate narratives in which attachment-related threats are recognized, competent help is provided, and the problem is resolved—is associated with adults’ autonomic and subjective emotional responses to infant distress and nondistress vocalizations. Adults who demonstrated low levels of secure base knowledge showed greater electrodermal reactivity and stronger declines in their feelings of love while they listened to a recording of an infant crying. In contrast, secure base knowledge was not significantly associated with adults’ responses to infant laughter. Results are discussed in terms of their role in extending prior research on the psychophysiology of adult attachment...

Generic language and speaker confidence guide preschoolers’ inferences about novel animate kinds.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

We investigated the influence of speaker certainty on 156 four-year-old children’s sensitivity to generic and nongeneric statements. An inductive inference task was implemented, in which a speaker described a nonobvious property of a novel creature using either a generic or a nongeneric statement. The speaker appeared to be confident, neutral, or uncertain about the information being relayed. Preschoolers were subsequently asked if a second exemplar shared the same property as the first. Preschoolers consistently extended properties to additional exemplars only when properties were described in a generic form by a confident or neutral speaker. If a speaker appeared to be uncertain or if statements were made in a nongeneric form, properties were not consistently extended beyond the first ...

Achieving a new dimension: Children integrate three stimulus dimensions in volume estimations.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

Although J. Piaget (1968) assumed that children up to 7 years old are unable to consider more than 1 stimulus dimension in their judgments, subsequent research has demonstrated that preschoolers can consider 2 dimensions, such as the width and length of rectangles to estimate their area (F. Wilkening, 1979). The present study addressed the question of whether children can also take 3 stimulus dimensions into account. Kindergartners, 1st and 3rd graders, and adults (N = 73) estimated the volume of cuboids that required the consideration of 3 dimensions: width, height, and length. The results showed that the majority of kindergartners already based their volume estimations on all 3 dimensions. A considerable proportion of kindergartners even integrated width, height, and length multiplicativ...

Preschoolers infer ownership from “control of permission”.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

Owners control permission—they forbid and permit others to use their property. So it is reasonable to assume that someone controlling permission over an object is its owner. The authors tested whether preschoolers infer ownership in this way. In the first experiment, 4- and 5-year-olds, but not 3-year-olds, chose as owner of an object a character who granted or denied another character permission to use it. In Experiment 2, older 3-year-olds chose as owner of an object a character who prevented another character from using it when prevention was accomplished by controlling permission but not otherwise. Younger 3-year-olds chose between the characters at chance. These findings indicate that preschoolers infer ownership from control of permission. (PsycINFO Database Record (c) 2009 APA, al...

Do perceived popular adolescents who aggress against others experience emotional adjustment problems themselves?

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

Aggression is associated with a host of behavioral, social, and emotional adjustment difficulties. However, some aggressive youth are perceived as “popular” by peers. Although these perceived popular aggressive youth appear relatively well adjusted, especially in the social domain, the emotional well-being of these youth is understudied. The current findings indicate that perceived popularity buffers adolescents who hurt others through relational aggression from internalizing symptoms. In contrast, perceived popularity did not buffer adolescents who engaged in overt verbal and physical aggression from internalizing symptoms. The results suggest that relationally aggressive perceived popular adolescents may be especially resistant to intervention if their aggression helps them manipulat...

Early math matters: Kindergarten number competence and later mathematics outcomes.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

Children’s number competencies over 6 time points, from the beginning of kindergarten to the middle of 1st grade, were examined in relation to their mathematics achievement over 5 later time points, from the end of 1st grade to the end of 3rd grade. The relation between early number competence and mathematics achievement was strong and significant throughout the study period. A sequential process growth curve model showed that kindergarten number competence predicted rate of growth in mathematics achievement between 1st and 3rd grades as well as achievement level through 3rd grade. Further, rate of growth in early number competence predicted mathematics performance level in 3rd grade. Although low-income children performed more poorly than their middle-income counterparts in mathematics ...

Parent–adolescent discrepancies in adolescents’ competence and the balance of adolescent autonomy and adolescent and parent well-being in the context of Type 1 diabetes.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

This study examined whether intrafamily discrepancies in perceptions of the adolescent’s competence and independence were associated with autonomy and well-being for adolescents and parents. The ways in which mothers and fathers consistently differed from their adolescent across measures of independence and competence regarding Type 1 diabetes, a stressful context for families, were examined with the latent discrepancy model. A sample of 185 adolescents (mean age = 12.5 years, SD = 1.3), their mothers, and participating fathers completed measures of the adolescent’s independence in completing diabetes tasks, problems with diabetes management, adherence to the medical regimen, measures of well-being, and metabolic control. The latent discrepancy model was conducted via structural equati...

Genetic variance in processing speed drives variation in aging of spatial and memory abilities.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

Previous analyses have identified a genetic contribution to the correlation between declines with age in processing speed and higher cognitive abilities. The goal of the current analysis was to apply the biometric dual change score model to consider the possibility of temporal dynamics underlying the genetic covariance between aging trajectories for processing speed and cognitive abilities. Longitudinal twin data from the Swedish Adoption/Twin Study of Aging, including up to 5 measurement occasions covering a 16-year period, were available from 806 participants ranging in age from 50 to 88 years at the 1st measurement wave. Factors were generated to tap 4 cognitive domains: verbal ability, spatial ability, memory, and processing speed. Model-fitting indicated that genetic variance for proc...

Goal directedness and decision making in infants.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

In this study, 24-month-olds learned to retrieve an object from a box by pressing a button, and then the object’s value was increased. After the object’s subsequent disappearance, these children were more likely to press the button to try to retrieve the object than were control 24-month-olds who had learned to retrieve the object but for whom the object’s value was unchanged. Such sensitivity to outcome value when selecting actions is a hallmark of decision making. However, 14- and 19-month-olds showed no such sensitivity. Possible explanations include that they had not learned the specifics of the action outcome; they had not acquired the necessary desire; or they had acquired both but did not integrate them to make a decision.

Longitudinal associations between emotion regulation and depression in preadolescent girls: Moderation by the caregiving environment.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

This study examined the prospective relations of preadolescent girls’ emotion regulation and parenting style with depressive symptoms. Participants were 225 children and their biological mothers recruited from a larger longitudinal community study. Girls’ observed positive and negative emotion during a conflict resolution task with mothers, their ability to regulate sadness and anger, and their perception of parental acceptance and psychological control were assessed at age 9. Depressive symptoms were assessed by self-report at ages 9 and 10. The results indicated interactions between child emotion characteristics and parenting in predicting later depression. Specifically, low levels of positive emotion expression predicted higher levels of depressive symptoms in the context of moderat...

Setting goals to switch between tasks: Effect of cue transparency on children’s cognitive flexibility.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

Three experiments examined the difficulty of translating cues into verbal representations of task goals by varying the degree of cue transparency (auditory transparent cues, visual transparent cues, visual arbitrary cues) in the Advanced Dimensional Change Card Sort, which requires switching between color- and shape-sorting rules on the basis of cues. Experiment 1 showed that 5- and 6-year-old children’s performance improved as a function of cue transparency. Experiment 2 yielded the same pattern of results and showed that cue transparency effects cannot be accounted for by cue format only. Finally, Experiment 3 examined the effect of cue transparency in 7- and 9-year-olds and adults. The effect decreased over age for accuracy performance but not for latencies, suggesting that under some...

The cognitive and linguistic foundations of early reading development: A Norwegian latent variable longitudinal study.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

The authors present the results of a 2-year longitudinal study of 228 Norwegian children beginning some 12 months before formal reading instruction began. The relationships between a range of cognitive and linguistic skills (letter knowledge, phoneme manipulation, visual–verbal paired-associate learning, rapid automatized naming (RAN), short-term memory, and verbal and nonverbal ability) were investigated and related to later measures of word recognition in reading. Letter knowledge, phoneme manipulation, and RAN were independent longitudinal predictors of early reading (word recognition) skills in the regular Norwegian orthography. Early reading skills initially appeared well described as a unitary construct that then showed rapid differentiation into correlated subskills (word decoding...

Parental involvement in middle school: A meta-analytic assessment of the strategies that promote achievement.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

Early adolescence is often marked by changes in school context, family relationships, and developmental processes. In the context of these changes, academic performance often declines, while at the same time the long-term implications of academic performance increase. In promoting achievement across elementary and secondary school levels, the significant role of families, family–school relations, and parental involvement in education has been highlighted. Although there is a growing body of literature focusing on parental involvement in education during middle school, this research has not been systematically examined to determine which types of involvement have the strongest relation with achievement. The authors conducted a meta-analysis on the existing research on parental involvement...

The relations of temperament reactivity and effortful control to children’s adjustment problems in China and the United States.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

The relations of parents’ and teachers’ reports of temperament anger–irritability, positive emotionality, and effortful control (attention focusing and inhibitory control) to children’s externalizing and internalizing problems were examined in Chinese (N = 382) and U.S. (N = 322) samples of school-age children. Results suggested that in both cultures, low effortful control and high anger–irritability were associated with high externalizing problems, although the relations were stronger in the Chinese sample than in the U.S. sample. Low positive emotionality was associated with high internalizing problems in both cultures. However, high positive emotionality was associated with noncomorbid externalizing problems (teachers’ reports) in the Chinese sample but not in the U.S. sampl...

Learning to form a spatial category of tight-fit relations: How experience with a label can give a boost.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

Two experiments explored the ability of 18-month-old infants to form an abstract categorical representation of tight-fit spatial relations in a visual habituation task. In Experiment 1, infants formed an abstract spatial category when hearing a familiar word (tight) during habituation but not when viewing the events in silence or when hearing a novel word. In Experiment 2, infants were given experience viewing and producing tight-fit relations while an experimenter labeled them with a novel word. Following this experience, infants formed the tight-fit spatial category in the visual habituation task, particularly when hearing the novel word again during habituation. Results suggest that even brief experience with a label and tight-fit relations can aid infants in forming an abstract categor...

Processes and content of narrative identity development in adolescence: Gender and well-being.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

The present study examined narrative identity in adolescence (14–18 years) in terms of narrative content and processes of identity development. Age- and gender-related differences in narrative patterns in turning point memories and gender differences in the content and functions for sharing those memories were examined, as was the relationship between narrative patterns and self-esteem. The narrative patterns focused on were meaning-making (learning from past events) and emotionality of the narratives, specified as overall positive emotional tone and redemptive sequencing. Results showed an age-related increase in meaning-making but no gender differences in the degree of meaning-making. Results further showed that gender predicted self-esteem and that boys evidenced higher self-esteem. E...

The acquisition of gender labels in infancy: Implications for gender-typed play.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

Two aspects of children’s early gender development—the spontaneous production of gender labels and gender-typed play—were examined longitudinally in a sample of 82 children. Survival analysis, a statistical technique well suited to questions involving developmental transitions, was used to investigate the timing of the onset of children’s gender labeling as based on mothers’ biweekly telephone interviews regarding their children’s language from 9 through 21 months. Videotapes of children’s play both alone and with mother during home visits at 17 and 21 months were independently analyzed for play with gender-stereotyped and gender-neutral toys. Finally, the relation between gender labeling and gender-typed play was examined. Children transitioned to using gender labels at appr...

Alternate models of sibling status effects on health in later life.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

Although siblings are thought to be influential in child development, little is known about the influence of sibling status on the health of older adults. Using structural equation modeling, the authors created and tested a series of models with data from a sample (N = 3,968) of 1957 high school graduates from the Wisconsin Longitudinal Study. The results indicated that socioeconomic status of origin, adolescent aptitude, and educational attainment did have significant total effects on health in later life, but sibling status did not. Adults who grew up in families of higher socioeconomic status and who had greater aptitude in high school attained more education, and this advantage, in turn, led to better health in later life. Although the final model was cross-validated, it was not equall...

New approaches to studying problem behaviors: A comparison of methods for modeling longitudinal, categorical adolescent drinking data.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

Analyzing problem-behavior trajectories can be difficult. The data are generally categorical and often quite skewed, violating distributional assumptions of standard normal-theory statistical models. In this article, the authors present several currently available modeling options, all of which make appropriate distributional assumptions for the observed categorical data. Three are based on the generalized linear model: a hierarchical generalized linear model, a growth mixture model, and a latent class growth analysis. They also describe a longitudinal latent class analysis, which requires fewer assumptions than the first 3. Finally, they illustrate all of the models using actual longitudinal adolescent alcohol-use data. They guide the reader through the model-selection process, comparing ...

Neither colorblind nor oppositional: Perceived minority status and trajectories of academic adjustment among Latinos in elite higher education.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

As more Latinos experience upward social mobility, it is increasingly necessary to challenge oppositional cultural assumptions to explain how perceived minority status barriers may influence their academic achievement. The present study builds on previous work that identified 3 distinct minority status orientations among Latino college students entering elite colleges—which the authors call assimilation, accommodation, and resistance. Using data from the National Longitudinal Survey of Freshmen, the authors examined how these orientations influence Latino students’ academic and social adjustment from their freshman to junior years of college. Latino students who most strongly questioned the openness of the opportunity structure to ethnic minorities—resisters—reported similar grades...

Children’s attention to interactions directed to others: Guatemalan mayan and european american patterns.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

This study investigated differences in attention and learning among Guatemalan Mayan and European American children, ages 5–11 years, who were present but not addressed while their sibling was shown how to construct a novel toy. Each child waited with a distracter toy for her or his turn to make a different toy. Nonaddressed children from Mayan traditional families (with little maternal involvement in Western schooling; n = 40) showed more sustained attention and learning than their counterparts from Mayan families with extensive involvement in Western schooling (n = 40) or European American children (with extensive family involvement in schooling; n = 40). The nonaddressed Mayan children from highly schooled families in turn attended more than the European American children. These findi...

The neural correlates of infant and adult goal prediction: Evidence for semantic processing systems.

Developmental Psychology — Fri, 08 May 2009 00:09:00 +0100

This study suggests that infants at 9 months anticipate goals and use similar cognitive mechanisms to adults in this task. In addition, this result suggests that language processing may derive from understanding action in early development.

A self-agency bias in preschoolers' causal inferences.

Developmental Psychology — Mon, 09 Mar 2009 05:00:00 +0100

Preschoolers' causal learning from intentional actions—causal interventions—is subject to a self-agency bias. The authors propose that this bias is evidence-based, in other words, that it is responsive to causal uncertainty. In the current studies, two causes (one child controlled, one experimenter controlled) were associated with one or two effects, first independently, then simultaneously. When initial independent effects were probabilistic, and thus subsequent simultaneous actions were causally ambiguous, children showed a self-agency bias. Children showed no bias when initial effects were deterministic. Further controls established that children's self-agency bias is not a wholesale preference but rather is influenced by uncertainty in causal evidence. These results demonstrate tha...

Children's use of mutual exclusivity to learn labels for parts of objects.

Developmental Psychology — Mon, 09 Mar 2009 05:00:00 +0100

In this study, the authors taught children part terms by outlining a novel part of a real object. We made mutual exclusivity available by showing children familiar whole objects with novel parts and unavailable by showing unfamiliar whole objects with novel parts. During test, the object was oriented with the part facing away from the child to distinguish pointing to the object from pointing to the part. Both 2-year-olds and 3-year-olds learned more part labels when mutual exclusivity was available. Thus, mutual exclusivity is indispensable even when part labeling is accompanied by naturalistic communicative gestures.

The transmission of racial attitudes within the family.

Developmental Psychology — Mon, 09 Mar 2009 05:00:00 +0100

Previous literature based on self-report measures has not found a clear relationship between the ethnic attitudes of White parents and those of their children. In particular, no study has evidenced such a relationship in the case of preschool children. In the present study, the authors measured parents' implicit and explicit racial attitudes as well as the racial attitudes of their 3- to 6-year-old children. They found that parents' explicit attitudes were not related to children's responses. In contrast, mothers' implicit attitudes (but not fathers' implicit attitudes) were significant predictors of children's attitudes. Results demonstrate that early racial attitudes might develop within the family. (PsycINFO Database Record (c) 2009 APA, all rights reserved) (Source: Developmental Psych...

Infants' ability to parse continuous actions.

Developmental Psychology — Mon, 09 Mar 2009 05:00:00 +0100

In a series of 3 experiments, the authors examined 6- and 8-month-old infants' capacities to detect target actions in a continuous action sequence. In Experiment 1, infants were habituated to 2 different target actions and subsequently were presented with 2 continuous action sequences that either included or did not include the familiar target actions. Infants looked significantly longer at the sequences that were novel. Experiment 2 presented the habituation and test trials in the reverse order. The results showed that infants habituated to the sequence still showed reliable evidence of recognizing the target action during the test trials. Experiment 3 was comparable to Experiment 2, except it tested whether infants could detect a different event segment, namely the transitions between ev...

The development of narrative identity in late adolescence and emergent adulthood: The continued importance of listeners.

Developmental Psychology — Mon, 09 Mar 2009 05:00:00 +0100

Research on narrative identity in late adolescence and early adulthood has not extensively examined how conversational storytelling affects the development of narrative identity. This is a major gap, given the importance of this age period for narrative identity development and the clear importance of parent–child conversations in the development of narrative identity. The authors present a series of 3 studies (n = 220) examining how late adolescents and early adults construct narrative identity in ways that are shaped by their listeners. The findings suggest that late adolescents and early adults construct more meaning-laden, interpretive accounts of their everyday experiences when they converse with responsive friends. Further, even within this sample's abbreviated age range, the autho...

The effects of socioeconomic status, race, and parenting on language development in early childhood.

Developmental Psychology — Mon, 09 Mar 2009 05:00:00 +0100

The authors examined the associations between socioeconomic status (SES), race, maternal sensitivity, and maternal negative-intrusive behaviors and language development in a sample selected to reduce the typical confound between race and SES (n = 146). Mother–child interactions were observed at 12 and 24 months (coded by randomly assigned African American and European American coders); language abilities were assessed at 18, 24, 30, and 36 months. For receptive language, race was associated with ability level, and maternal sensitivity and negative-intrusive parenting were related to rate of growth. For expressive communication, race, SES, and maternal sensitivity were associated with rate of growth; race moderated the association between negative-intrusive parenting and rate of growth su...

Sympathy through affective perspective taking and its relation to prosocial behavior in toddlers.

Developmental Psychology — Mon, 09 Mar 2009 05:00:00 +0100

In most research on the early ontogeny of sympathy, young children are presented with an overtly distressed person and their responses are observed. In the current study, the authors asked whether young children could also sympathize with a person to whom something negative had happened but who was expressing no emotion at all. They showed 18- and 25-month-olds an adult either harming another adult by destroying or taking away her possessions (harm condition) or else doing something similar that did not harm her (neutral condition). The “victim” expressed no emotions in either condition. Nevertheless, in the harm as compared with the neutral condition, children showed more concern and subsequent prosocial behavior toward the victim. Moreover, children's concerned looks during the harmf...
