Evaluating the impact of dyslexia laws on the identification of specific learning disability and dyslexia.
Abstract Dyslexia is a specific learning disability that impacts word reading accuracy and/or reading fluency. Over half of the states in the USA have passed legislation intended to promote better identification of individuals with dyslexia. To date, no study has been conducted to investigate the potential impact of state laws on the identification of specific learning disability (SLD), and limited data has been presented on the rate at which students in public school settings are identified with dyslexia. The first aim of the current study was to determine if any detectable changes in the identification rates of ...

Using conceptual change theory to help preservice teachers understand dyslexia.
Abstract Recently, many states passed laws requiring pre- and in-service teachers to receive professional development in dyslexia awareness. Even though misconceptions regarding dyslexia are widespread, there is a paucity of research on how to effectively remove misconceptions and replace them with accurate knowledge. The purpose of this study was to determine whether a researcher-created refutation text grounded in conceptual change theory could produce significant conceptual change in preservice teacher knowledge of dyslexia when compared with a control text about dyslexia (Dyslexia Basics, International Dyslexi...

False memory for orthographically versus semantically similar words in adolescents with dyslexia: a fuzzy-trace theory perspective.
Abstract The presented research was conducted in order to investigate the connections between developmental dyslexia and the functioning of verbatim and gist memory traces-assumed in the fuzzy-trace theory. The participants were 71 high school students (33 with dyslexia and 38 without learning difficulties). The modified procedure and multinomial model of Stahl and Klauer (simplified conjoint recognition model) was used to collect and analyze data. Results showed statistically significant differences in four of the model parameters: (a) the probability of verbatim trace recollection upon presentation of orthograph...

Reading and reading-related skills in adults with dyslexia from different orthographic systems: a review and meta-analysis.
Abstract An individual diagnosed with dyslexia in childhood typically remains dyslexic throughout his/her life. However, the cognitive profile of adults with dyslexia has been less explored than that of children. This meta-analytic study is intended to clarify three questions: (1) To what extent, and in what manner, do adults with reading difficulties (dyslexia) differ from typical adult readers in measures of reading and writing competence and related cognitive skills?; (2) To what extent do speed measures pose a greater challenge than accuracy measures in an adult population that has already had years of print e...

Short-term memory for order but not for item information is impaired in developmental dyslexia.
Abstract Recent findings suggest that people with dyslexia experience difficulties with the learning of serial order information during the transition from short- to long-term memory (Szmalec et al. Journal of Experimental Psychology: Learning, Memory, & Cognition 37(5): 1270-1279, 2011). At the same time, models of short-term memory increasingly incorporate a distinction of order and item processing (Majerus et al. Cognition 107: 395-419, 2008). The current study is aimed to investigate whether serial order processing deficiencies in dyslexia can be traced back to a selective impairment of short-term memory f...

Dyslexia and voxel-based morphometry: correlations between five behavioural measures of dyslexia and gray and white matter volumes.
We presented an overview of uncorrected clusters of voxels (p < 0.05, cluster size k > 200) with reduced or increased GM volume. We found four significant correlations between factors of dyslexia representing various behavioural measures and the clusters found in the first analysis. In the whole sample, a factor related to performances in spelling correlated negatively with GM volume in the left posterior cerebellum. Within the group of dyslexics, a factor related to performances in Dutch-English rhyme words correlated positively with GM volume in the left and right caudate nucleus and negatively with increas...

NL reading skills mediate the relationship between NL phonological processing skills and a foreign language (FL) reading skills in students with and without dyslexia: a case of a NL (Polish) and FL (English) with different degrees of orthographic consistency.
Abstract The aim of our study was to examine the relationship between NL (Native Language: Polish) phonological processing skills (verbal and phonological short-term memory, phoneme segmentation and blending, rapid automatised naming (RAN)) and the accuracy and fluency of NL and English as a Foreign Language (EFL) word and nonword decoding and word recognition skills of Polish students with and without dyslexia. Sixty-three (45%) high school and junior high school students with and 78 (55%) without dyslexia participated. We found that dyslexia, years of studying EFL at school and privately, NL phoneme blending and...

Music-related abilities among readers with dyslexia.
Abstract Research suggests that a central difficulty in dyslexia may be impaired rapid temporal processing. Good temporal processing is also needed for musical perception, which relies on the ability to detect rapid changes. Our study is the first to measure the perception of adults with and without dyslexia on all three dimensions of music (rhythm, pitch, and spectrum), as well as their capacity for auditory imagery and detection of slow changes, while controlling for working memory. Participants were undergraduate students, aged 20-35 years: 26 readers with dyslexia and 30 typical readers. Participants complete...

Inter-letter spacing, inter-word spacing, and font with dyslexia-friendly features: testing text readability in people with and without dyslexia.
Abstract Over the last years, several studies have suggested a possible link between dyslexia and deficits in low-level visual processing (e.g., excessive crowding). At the same time, specially designed "dyslexia-friendly" fonts appeared on the market. This class of fonts presents two main features: the particular graphic characteristics of the letterform designed to avoid confusion between similarly shaped letters, and wider inter-letter and inter-word spacing to limit crowding. The literature testing the efficacy of "dyslexia-friendly" fonts in improving reading accuracy and increasing reading speed is controver...

Compensation for poor character learning: intact visual and phonetic strategies among Chinese children with dyslexia.
Abstract The present study investigated whether and to what extent children with dyslexia utilize visual and phonetic strategies in character learning. A paired associate learning paradigm was used in two experiments to train children's pronunciation-orthography associations of novel words, with a recall task 1 week later for retention. Experiment 1 included 32 Mandarin-speaking fifth graders with dyslexia (dyslexia group) and 28 age-matched peers (comparison group) and manipulated the availability of an arbitrary bolded stroke in Chinese character (visual cue, available vs. unavailable) of eight low-frequency re...

Project DyAdd: Implicit learning in adult dyslexia and ADHD.
In this study of the project DyAdd, implicit learning was investigated through two paradigms in adults (18-55 years) with dyslexia (n = 36) or with attention deficit/hyperactivity disorder (ADHD, n = 22) and in controls (n = 35). In the serial reaction time (SRT) task, there were no group differences in learning. However, those with ADHD exhibited faster RTs compared to other groups. In the artificial grammar learning (AGL) task, the groups did not differ from each other in their learning (i.e., grammaticality accuracy or similarity choices). Further, all three groups were sensitive to fragment overlap between...

Identifying dyslexia in adults: an iterative method using the predictive value of item scores and self-report questions.
Abstract Methods for identifying dyslexia in adults vary widely between studies. Researchers have to decide how many tests to use, which tests are considered to be the most reliable, and how to determine cut-off scores. The aim of this study was to develop an objective and powerful method for diagnosing dyslexia. We took various methodological measures, most of which are new compared to previous methods. We used a large sample of Dutch first-year psychology students, we considered several options for exclusion and inclusion criteria, we collected as many cognitive tests as possible, we used six independent sources...

Examining the relationship between home literacy environment and neural correlates of phonological processing in beginning readers with and without a familial risk for dyslexia: an fMRI study.
Abstract Developmental dyslexia is a language-based learning disability characterized by persistent difficulty in learning to read. While an understanding of genetic contributions is emerging, the ways the environment affects brain functioning in children with developmental dyslexia are poorly understood. A relationship between the home literacy environment (HLE) and neural correlates of reading has been identified in typically developing children, yet it remains unclear whether similar effects are observable in children with a genetic predisposition for dyslexia. Understanding environmental contributions is impor...

Children with dyslexia in different cultures: Investigation of anxiety and coping strategies of children with dyslexia in Indonesia and Germany.
This study investigates the anxiety profile and coping strategies of children with and without dyslexia from different cultures. A total of 124 children ranging from the age of eight to eleven from Indonesia (n = 64) and Germany (n = 60) were administered a coping and an anxiety scale. Around 50% of the sample were diagnosed with dyslexia and therefore were specifically asked what strategies they implemented in dealing with their difficulties in reading. Findings indicate that dyslexia and cultural factors have distinct contributions in explaining the variance of anxiety and coping strategies. Specifically, dyslexi...

E-book reading hinders aspects of long-text comprehension for adults with dyslexia.
This study used long-text reading to investigate (1) different aspects of reading comprehension skills (literal and inferential processes, location of events within a story, and reconstruction of the plot) among university students with dyslexia and (2) the impact of e-book reading on reading comprehension in this population. Thirty adults with dyslexia and 30 matched skilled readers read the same text presented from a printed book and an e-book (Amazon Kindle). Questions were open-ended and both questions and answers used oral format. Results showed that with the printed book, dyslexic adults performed similarly to skille...
