Accurately Assessing Visual Deficits in Children With Developmental Dyslexia —Reply
In Reply We thank Elder and Gole for their thoughtful comments on our article. Citing Ayton et al, they contend that the Developmental Eye Movement (DEM) test is not a valid indicator of saccadic eye movements. The Ayton et al study, however, had its own limitations: (1) it included only typical readers (restricting variability and hence correlations); (2) it did not consider normative age-associated changes in eye movements; and (3) it used saccadic measures of gain, latency, and velocity, rather than typical measures associated with reading, such as fixations and regressions. A 2018 study by Moiroud et al in children wit...

Accurately Assessing Visual Deficits in Children With Developmental Dyslexia
To the Editor The recent article by Raghuram et al makes numerous assumptions about the association between eye movements and reading. One important assumption is that the Developmental Eye Movement (DEM) test is a measure of eye movements. However, the original article describing this test does not appear to provide any empirical evidence that there is any association between saccadic eye movement and reading. It does not seem sufficient for Raghuram et al to dismiss this assumption with the statement, “Some have questioned whether DEM is a valid measure of saccadic eye movements.”(p1094) Ayton et al have shown that t...

Learning Lexical Information Depends Upon Task, Learning Approach, and Reader Subtype.
In this study, 45 children participated in three tasks that differentially tested PO and semantic attributes of novel pseudo-words learned through two learning approaches. Children were classified into groups as having dyslexia (DYS), having specific reading comprehension deficits (S-RCDs), or being typically developing readers (TD). Differences were found between groups, with S-RCD poorer than TD on semantic but not PO components of learning. Children with DYS displayed impaired results on both semantic and PO learning but showed an interaction on task by LA performance. Specifically, in the DYS group, isolation LA yielde...

Exploring the use of network meta-analysis in education: examining the correlation between ORF and text complexity measures.
This article provides preliminary evidence to answer that question using an approach borrowed from the field of medicine-Network Meta-Analysis (NMA; Lumley Statistics in Medicine, 21, 2313-2324, 2002). A systematic search yielded 5 studies using 19 different text complexity tools with ORF as the reading outcome measured. Both a frequentist and Bayesian NMA were conducted to pool the correlations of a given text complexity tool with students' ORF. While the results differed slightly across the two approaches, there is preliminary evidence in support of the hypothesis that text complexity tools which incorporate more fine-gr...

Lexical and grammatical development in children at family risk of dyslexia from early childhood to school entry: a cross-lagged analysis.
Abstract The aim of this study was to examine (a) the development of vocabulary and grammar in children with family-risk (FR) of dyslexia and their peers with no such risk (NoFR) between ages 1;6 and 6;0, and (b) whether FR-status exerted an effect on the direction of temporal relationships between these two constructs. Groups were assessed at seven time-points using standardised tests and parental reports. Results indicated that although FR and NoFR children had a similar development in the earlier years, the FR group appeared to perform significantly more poorly on vocabulary at the end of the preschool period. ...

Auditory, Visual, and Cross-Modal Temporal Processing Skills Among Chinese Children With Developmental Dyslexia.
Abstract The present study examined whether temporal processing (TP) is associated with reading of a non-alphabetic script, that is, Chinese. A total of 126 primary school-aged Chinese children from Taiwan (63 children with dyslexia) completed cross-modal, visual, and auditory temporal order judgment tasks and measures of Chinese reading and literacy-related skills. The results showed that typically developing children and children with dyslexia differed in all TP skills. Structural equation modeling indicated that cross-modal TP contributed independently to character recognition in the entire sample if the signif...

Developmental dyslexia: How taxonomic and thematic organization affect working memory recall.
Abstract Semantic long-term memory (LTM) representations can be distinguished in two main classes: taxonomic (i.e., abstract) and thematic (i.e., concrete, experiential). In typically developing children, taxonomies are usually acquired after thematic representations. In the current study, we investigated how LTM semantic representations modulate working memory (WM) recall in children with developmental dyslexia (DD). A sample of children with DD from primary and secondary school paired with a control group for age, gender, schooling, and IQ was administered a semantic WM (SWM) dual task. Here, children had to lis...

Delayed development of phonological constancy in toddlers at family risk for dyslexia
Publication date: November 2019Source: Infant Behavior and Development, Volume 57Author(s): Marina Kalashnikova, Usha Goswami, Denis BurnhamAbstractPhonological constancy refers to infants’ ability to disregard variations in the phonetic realisation of speech sounds that do not indicate lexical contrast, e.g., when listening to accented speech. In typically-developing infants, this ability develops between 15- and 19-months of age, coinciding with the consolidation of infants’ native phonological competence and vocabulary growth. Here we investigated the developmental time course of phonological constancy in infants at...

Executive Functioning and Narrative Language in Children With Dyslexia.
Conclusions The range of performance found across language measures suggests that it may be important to include a variety of language measures assessing both structural and functional language skills when evaluating children with dyslexia. Including cognitive measures of executive functioning may also be key to determine if deficits in working memory updating are contributing to functional expressive language difficulties.

Another Temporal Processing Deficit in Individuals With Developmental Dyslexia: The Case of Normalization for Speaking Rate.
Conclusions Individuals with DD are impaired not only in tasks involving direct temporal processing, as shown in previous studies but also in the use of temporal information of a context that impacts the perception of subsequent target words. This inability to fully utilize rate normalization processes may influence the formation of abstract phonological representations in individuals with DD.

Dyslexia: What Reading Teachers Need to Know
AbstractDyslexia is a neurological language ‐based learning disability. Several legislative bills related to dyslexia have recently been introduced in the United States so dyslexia can be understood and interventions in reading instruction can be provided. Studies have shown measurable improvements in the language areas of the brain's left hemisphere after reading interventions with students with dyslexia, and multisensory teaching strategies can be the difference between academic success and academic failure and frustration. Effective methods for working with students with dyslexia support an explicit, systematic, cumul...

Association between KIAA0319 SNPs and risk of dyslexia: a meta-analysis.
Abstract The aetiology of developmental dyslexia (DD) is complex; although candidate genes have been suggested, the molecular mechanism and risk factors remain unknown. The KIAA0319 gene is functionally related to neuronal migration and axon growth, and several studies have examined associations between KIAA0319 polymorphisms with DD, but the results remain inconsistent. The sample size affects the results of meta-analysis. The aim of this meta-analysis was to clarify the effect of KIAA0319 polymorphisms on dyslexia susceptibility according to the available evidence.

Phonemes, words, and phrases: Tracking phonological processing in pre-schoolers developing dyslexia.
CONCLUSION: Our findings complement the picture of phonological processing in dyslexia by confirming difficulties in segmental phonology and showing that prosodic processing is affected for the smaller word level, but not the larger phrase level. SIGNIFICANCE: These findings might have implications for early interventions, considering both phonemic awareness and stress pattern training. PMID: 31200240 [PubMed - as supplied by publisher]

Predictors for grade 6 reading in children at familial risk of dyslexia.
Abstract The present study investigates whether grade 6 reading outcomes, reading fluency, and reading comprehension can be predicted by grade 3 reading fluency, familial risk of dyslexia (FR), and grade 3 reading related skills: rapid automatized naming (RAN), phonological awareness (PA), and vocabulary. In a sample of 150 children, of whom 83 had a parent with dyslexia, correlation and regression analyses were performed. FR, measured on a continuous scale, was by itself related to all outcomes. However, FR did not explain any variance on top of grade 3 reading fluency. Grade 3 reading fluency strongly predicted ...

The multiple deficit model of dyslexia: what does it mean for identification and intervention?
Abstract Research demonstrates that phonological skills provide the basis of reading acquisition and are a primary processing deficit in dyslexia. This consensus has led to the development of effective methods of reading intervention. However, a single phonological deficit is not sufficient to account for the heterogeneity of individuals with dyslexia, and recent research provides evidence that supports a multiple-deficit model of reading disorders. Two studies are presented that investigate (1) the prevalence of phonological and cognitive processing deficit profiles in children with significant reading disabilit...

Effect of chunk strength on the performance of children with developmental dyslexia on artificial grammar learning task may be related to complexity.
Abstract There's a long held view that chunks play a crucial role in artificial grammar learning performance. We compared chunk strength influences on performance, in high and low topological entropy (a measure of complexity) grammar systems, with dyslexic children, age-matched and reading-level-matched control participants. Findings show that age-matched control participants' performance reflected equivalent influence of chunk strength in the two topological entropy conditions, as typically found in artificial grammar learning experiments. By contrast, dyslexic children and reading-level-matched controls' perform...
