Forty children with ADHD were randomly assigned into exercise or control groups. Participants in the exercise group performed a moderate intensity aerobic exercise for 30 min, whereas the control group watched a running/exercise-related video. Neuropsychological tasks, the Stroop Test and the Wisconsin Card Sorting Test (WCST), were assessed before and after each treatment. The results indicated that acute exercise facilitated performance in the Stroop Test, particularly in the Stroop Color-Word condition. Additionally, children in the exercise group demonstrated improvement in specific WCST performances in Non-perseverative Erro...

This could, in part, be caused by a Babylonic incongruence between laypeople's and experts' use of cognition words or "jargon." The present study examined the concurrency of experts and laypeople for 18 neuropsychological tests in the cognitive domains "language," "memory," "attention/concentration," "perception," and "thinking" (executive functioning). This was done by correlating the classifications of the laypeople and experts for individual tests and within each domain. A high domain concurrency was found, indicated by domain correlations of the classifications between laypeople and experts ranging fro...

In addition to stand-alone measures, built-in, or embedded measures of effort have been derived for a limited number of standard neurocognitive tests. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a widely used brief battery, employed as a core diagnostic tool in dementia and as a neurocognitive screening battery or tracking/outcome measure in a variety of other disorders. An effort index (EI) for the RBANS has been published previously (Silverberg, N. D., Wertheimer, J. C., & Fichtenberg, N. L. 2007.

TOMM Trial 1 demonstrated impressive diagnostic accuracy for determining both adequate and suboptimal levels of effort; various cut scores and classification statistics are presented. The optional Retention trial from the TOMM also increased the hit rate 16% in the detection of poor effort. Clinical implications, limitations, and directions for further research are discussed.

The current study explored whether Symbol Span, a novel Wechsler Memory Scale-fourth edition measure of supraspan visual attention, could be used to discriminate adequate effort from suboptimal effort. Archival data were collected from 136 veterans classified into Poor Effort (n = 42) and Good Effort (n = 94) groups based on symptom validity test (SVT) performance. The Poor Effort group had significantly lower raw scores (p < .001) and age-corrected scaled scores (p < .001) than the Good Effort group on the Symbol Span test. A raw score cutoff of &lt...

However, the Wechsler Adult Intelligence Scale-IV (Wechsler, 2008) altered Digit Span in meaningful ways, necessitating another look at Digit Span as an embedded measure of malingering. Using a simulated malingerer design, we examined the predictive accuracy of existing Digit Span validity indices and explored whether patterns of performance utilizing the new version would provide additional evidence for malingering. Undergraduates with a history of mild head injury performed with best effort or simulated impaired cognition and were also compared with a large sample of non-head-injured controls. Previously established cutoffs for the age-corrected scaled ...

In Study 1, the performance of Australian-English-speaking adults with mild AD was compared with that of native Australian-English- and Korean-speaking patients with mild AD. Compared with controls, patients with AD from both language groups showed large but equivalent impairments in total recall, delayed recall, rate of learning, and primacy and retention-weighted recall (RWR) measures on the ISLT. In Study 2, the rate of deterioration in verbal memory over 1 year was examined in groups of native Canadian-English, French, and Korean speakers with mild AD using the total re...

Results revealed that the miD group performed comparably with controls and significantly better than the MDD group on several CVLT indices. Moreover, cluster analysis revealed three distinct groups, consistent with theoretical representations of "normal," "subcortical," and "cortical" verbal learning and memory profiles. The majority of the miD group showed "normal" profiles (74%), whereas most individuals with MDD displayed "subcortical" profiles (54%).

These efforts have directly impacted current policy on strategies for injury assessment and return-to-play by athletes after concussion. Many states are considering legislation requiring (a) education of athletes, parents, coaches, and school/organization officials on the recognition, evaluation, and management of SRCs; (b) removal from play of any youth athlete that is suspected of having sustained a concussion; and (c) not allowing the s...

When these tests are administered to patients with multiple sclerosis (MS), the findings pertaining to planning "performance" have been conflicting. Possible reasons for failures to find deficits in planning performance among MS patients are: (a) the patients typically have relapsing-remitting MS (RRMS) of mild severity and short duration and thus little cognitive impairment relative to those with more advanced disease; (b) the problems composing the tests are too simple and differences between patients and controls are therefore obscured by ceiling effects; and (c) the scoring system typically used permits participant...

The two approaches were compared against empirically derived base rates for a multitest co-normed battery of cognitive measures. Estimates were compared across a variety of conditions including age and different α levels (N =3,356). Monte Carlo R(2) estimates ranged from .980 to .997 across five different age groups, indicating a good fit. In contrast, the binomial model fit estimates ranged from 0.387 to 0.646. Results confirm that the binomial model is insufficient for estimating base rates because it does not take into account correlations among measures in a multitest battery. Although the Monte Carlo model produced more accurate results, minor ...

The current study used item response theory (IRT) methods to determine whether the serial position effect poses a threat to the construct validity of immediate list recall as a measure of verbal episodic memory. Archival data were obtained from a national sample of 4,212 volunteers aged 28-84 in the Midlife Development in the United States study. Telephone assessment yielded item-level data for a single immediate recall trial of the Rey Auditory Verbal Learning Test (RAVLT).

There are currently several free-standing symptom validity tests (SVTs), as well as a number of empirically derived embedded validity indices, that have been developed to assess that an examinee is putting forth an optimal level of effort during testing. The use of embedded validity indices is attractive since they do not increase overall testing time and may also be less vulnerable to coaching.

Participants included 53 children and adolescents between six and 19 years (mean age = 12.4, SD = 4.1) who were followed through a neurology clinic at a tertiary care hospital. Several cutoff scores were examined, with the goal of maximizing positive predictive (accurate detection of failure on the TOMM) and negative predictive (accurate detection of passing the TOMM) values. Every participant who scored ≥36 on Trial 1 (n = 50) went on to pass the TOMM. This study is the first step in providing evidence that performance on Trial 1 might be used as a quick screening measure of overall performance on th...

These formulae were validated in a small sample of patients with amnestic Mild Cognitive Impairment. However, further validation is clearly needed. The current study applied these formulae to a sample of 1,059 patients referred to a dementia clinic and compared the premorbid estimates of memory functioning with current memory abilities. Large and statistically significant differences were observed in the current sample, with premorbid memory scores exceeding current memory scores. Although some cautions should be observed when using these estimates clinically, growing support for these estimates of premorbid memory abi...

Sixteen patients, 16 unaffected siblings, and 17 healthy control subjects underwent a battery of neuropsychological tasks that have so far yielded mixed findings in performance differences. Both groups had prolonged reaction times compared with controls in sustained attention tasks; the siblings made more false alarms in the working memory task, but only the patients' performance was poorer in the executive function tasks. These findings further support sustained attention and working memory deficits as potential endophenotypes of schizophrenia. Reaction time and false alarm rates are suggested as additional use...

The current study found that older adolescents and adults with both disorders also had more difficulties on processing speed and working memory measures than individuals who only had ADHD. There were no differences among non-timed EF scores. These results add support to the premise that common underlying features may be contributing to the high co-morbidity between these disorders and associated cognitive weaknesses. PMID: 21613301 ...

The purpose of this study was to investigate the test-retest reliability of the two attention tests in schizophrenia. A rater administered both tests on 147 participants with schizophrenia twice at a 1-week interval. Test-retest reliability was determined through the calculation of the intra-class correlation (ICC) coefficient. We also carried out the Bland-Altman analysis, which include a scatter plot of the differences between test and retest against their mean. System biases were evaluated by use of a paired t-test.

The Taiwanese version of the PRMQ was examined in an adult sample (n = 269, age range: 19-95). The 11-item Taiwanese PRMQ demonstrated acceptable internal consistency (Cronbach's α = 0.82-0.90) as well as a tripartite structure with one general Episodic Memory factor and one specific Prospective Memory factor. There was no gender effect, but older adults reported better prospective memory performance, and individuals with a higher level of education rated less retrospective memory failure. Preliminary Taiwanese normative data are als...

For this reason, a simple, reliable, and inexpensive method of early AD detection is urgently required. The location of neuropathological changes in AD patients indicates the potential diagnostic utility of olfactory tests. The purpose of this study was to compare odor identification performance among Polish subjects and to define the correlation between olfactory deficits and cognitive impairment. Olfactory identification performance was established in AD patients, and young and elderly healthy subjects using the Pocket Smell Test. AD Assessment Scale, the cognitive subscale, was used to evaluate cognitive functioning in the elderly participants. C...

Performance on the Test of Memory Malingering (TOMM) and Word Memory Test (WMT) was used for classification. Individuals who failed the TOMM or WMT were almost six times more likely to fail the CVMT validity criteria than those who passed the TOMM or WMT. The addition of compensation seeking increased this odds ratio to 9.80. The area under the curve for the latter classification was 0.74. Maximum likelihood ratio optimization of the CVMT validity test cutoff score indicated sensitivity of 0.25 and specificity o...

Performance on three immediate and one delayed recall trials, and additional measures of encoding and forgetting, is presented for 492 patients and 260 healthy community controls. Results indicated that age and sex (both groups) and IQ (schizophrenia group only) significantly influenced performance. Norms are presented, as means and standard deviations, stratified accordingly. Additional between-groups analysis clearly shows a significant memory deficit in schizophrenia even when patients are matched on IQ, age, and sex with healthy controls.

A comparison was made of the test performance and performance on the embedded Symptom Validity Tests (SVTs) with a control for multicolinearity utilized. Using the nine embedded SVTs in the MNB, the incidence of poor effort fell at 26% of the total sample. Involvement in litigation was related to more failures on the individual SVTs. The correlation between failed effort measures and the Overall Test Battery Mean (OTBM) was consistently negative, regardless of litigation status, in that more failures were associated with lower OTBM scores.

Executive function performance within the ADHD subtypes and the effects of comorbidity were also investigated. Five hundred Chinese boys (375 with ADHD and 125 controls) aged 6-15 completed a battery of EF tests. Boys with all types of ADHD performed worse in all of the EF tests than age- and intelligence quotient-matched healthy controls. The boys with the inattention ADHD subtype and the combined subtype showed similar impairments across different EF tasks, whereas the boys with the hyperactive-impulsive ADHD subtype primarily displayed deficits in theory of mind and visual memory.

Therefore, the aim of this study is to analyze the peripheral psychophysiological correlates (electrodermal conductance and heart rate) during the performance of the Victoria Symptom Validity Test (VSVT). The sample of this study was composed of 30 participants who underwent the VSVT under two conditions: Exaggeration of cognitive deficits (ECD) and normal effort. Our results showed differences on skin conductance between correct answers and errors limited to the decision-making phase of the ECD condition.

Two major reasons for illiteracy can be distinguished, social (e.g., absence of schools), and personal (e.g., learning difficulties). Without written language, our knowledge of the external world is partially limited by immediate sensory information and concrete environmental conditions.

Additionally, the differences between children with early and late seizure onset were explored. Results indicated comparable intelligence among all groups; however, the FLE cohort performed worse than controls on executive tests. The age of seizure onset differentially affected executive performance, such that early FLE onset resulted in greater executive dysfunction. The implications of these findings are discussed.

In recent years, however, studies have indicated that cross-sectional normative samples of older adults represent an admixture of individuals who are indeed cognitively normal (i.e., disease-free) and individuals with incipient neurodegenerative disease. Theoretically, the "contamination" of cross-sectional normative samples with cases of preclinical dementia can lead to underestimation of the test mean and overestimation of the variance, thus reducing the clinical utility of th...

In the 20th century, psychological and neuropsychological tests were first employed as both diagnostic and prognostic measures. The contemporary practice of epilepsy evaluation and management includes neuropsychology as a critical component of epilepsy care and research, and epilepsy and neuropsychology have enjoyed a very special and synergistic relationship. This paper reviews how epilepsy has shaped the practice of neuropsychology as a clinical service by asking critical questions that only neuropsychologists were in a position to answer, and how clinical care of epilepsy pa...

The MMPI-2-RF over-reporting validity scales were more strongly associated with mean Memory Complaints Inventory scores than their MMPI-2 counterparts (d = 0.22 to 0.49). RBS showed the strongest relationship with memory complaints. Regression analyses demonstrated the incremental validity of the MMPI-2-RF Infrequent Responses, Infrequent Psychopathology Responses, Infrequent Somatic Responses, and FBS-r scales relative to MMPI-2 F, Fp, and FBS in predicting memory complaints. This is consistent with the development objectives of the MMPI-2-RF validity scales as more efficient and sensitive measures of symptom over-reporting.

Undergraduate participants (n = 120; 60 men, 60 women) were randomly assigned to one of four groups based on the hand used in a copy trial and a recall test. Hand use had a minimal effect on performance in the copy trial. However, recall accuracy was lower when the non-dominant left hand was used in the copy trial than when the dominant right hand was used, regardless of the hand used in the recall test. These findings are important from a clinical perspective, especially in cases in which patients use the non-dominant hand due to hemiplegia of the dominant hand when conducting the ROCFT.

Although this topic has received increased attention in the literature recently, the issue remains unresolved. Evidence supporting a detrimental cognitive effect has been reported at a sub-concussive level and following one, two, and three or more previous concussions. However, numerous studies have been unable to replicate these findings. Additionally, discrepancies between neuropsychological testing formats have been identified, where studies utilizing traditional tests tend to support the notion of detrimental cognitive effects whereas studies with computerized tests have tended to demonstrate no effect.

This paper demonstrates how with only basic test-retest data and a series of simple expressions, the clinician/researcher can implement the majority of contemporary RC model(s). Though sharing a fundamental structure, RC models vary in how they derive predicted retest scores and standard error terms. Published test-retest normative data and a simple case study are presented to demonstrate how to calculate several well-known RC scores. The paper highlights the circumstances under which models will diverge in the estimation of RC. Most importantly variations in individual's performanc...

Our objective was to examine the utility of previously proposed symptom validity measures (i.e., the Dyslexia Assessment of Simulation or Honesty [DASH] and the resulting Feigning Index [FI]) in discriminating students with genuine RDs from sophisticated simulators given ample time to prepare, who were warned that noncredible performance could be detected. The DASH correctly classified almost 83% of coached simulators with no false positives. The FI accurately classified 86% of ...

Although standardized regression-based (SRB) prediction formulas may be useful in determining change, SRBs have not been widely applied to older adults. The current study sought to develop SRB formulas on a group of 127 community-dwelling older adults for several widely used neuropsychological measures. In addition to baseline test scores and demographic information, the current study also examined the role of short-term practice effects in predicting test scores after 1 year. Consistent with prior resear...

The purpose of the study was to establish the validity and reliability of the Turkish version of IQCODE (IQCODE-T) and the ability of the questionnaire to distinguish between older adults with DSM-IV-TR dementia (n = 100) and healthy control participants (n = 60). In addition, the power of the IQCODE-T to distinguish between patients with depression and dementia was investigated. The Mini-Mental State Examination (MMSE) was performed on all participants and the IQCODE-T was administered to their informants. The IQCODE-T, which was not associated with age or education of the patients, ...

Arch Clin Neuropsychol. 2009 Dec 16; Authors: Brooks BL, Iverson GL Clinicians can use the prevalence of low scores to help interpret test performance. However, this information is limited for most test batteries. In 2007, Crawford, Garthwaite, and Gault presented Monte Carlo simulation software for estimating the base rates of low scores for any battery of tests. The purpose of this study is to examine the accuracy of a Monte Carlo simulation program for estimating the base rates of low scores. Base rates of low scores were: (a) calculated from large normative samples (actual base rates) for the Neuropsychological Assessment Battery and the Wechs...

Clinically, the sample was characterized by elevated rates of developmental disorders (49%), personality disorders (54%), Axis I psychiatric disorders (45%), substance abuse (86%), and history of violence (43%). By statute, killing more than one person is an aggravating factor in many jurisdictions that renders a murder defendant eligible for the death penalty. Individuals who committed a single murder were characterized by executive dysfunction, lower intelligence, slower speed of information processing, and a higher frequency of developmental disorders (58%), relative to tho...

The relationship between self-reported memory, dissociation, emotional problems, and objective cognitive functioning was examined in 79 MS patients. Increased self-reported memory problems were significantly associated with higher levels of normative dissociation. Self-reported memory problems were also associated with more reports of depression, anxiety, and neuroticism. Consistent with expectations, self-reported memory was not significantly associated with performance on any of the neuropsychological variables. The present study then evaluated a theoretical causal model with normative diss...

Loss of specificity in ABM retrieval has been observed in people with mild to moderate Alzheimer's disease (AD). Our aim was to extend these findings to subjects with amnestic mild cognitive impairment (aMCI) and very early AD. We performed a cued ABM task with both subject groups and healthy elderly controls. Although aMCI participants performed better than early AD subjects both showed reduced specificity of ABM retrieval when compared with controls. We conclude that qualitative memory retrieval deficits could contribute to social functioning impairment in people with aMCI and early AD, and highlight the complexity of symptoms already ...

Whether impaired learning strategies are already present in subjects with prodromal AD remains unknown. The aim of the present study was to investigate the predictive accuracy of learning strategies for AD in subjects with Mild Cognitive Impairment (MCI). Subjects with MCI (n = 202) were selected from the Maastricht Memory Clinic. Subjects were reassessed over a period of 10 years. Fifty-five of the 202 subjects converted to AD. Learning strategies investigated were subjective organization and serial clustering. Lower scores of subjective organization were associated with a higher risk for AD (OR = 2.1, p = .002). Seria...
