This article reviews the results of a meta-analysis of the experimental published literature that compares the academic, cognitive, and behavioral performance of adults with reading disabilities (RD) with average achieving adult readers. The meta-analysis shows that deficits independent of the classification measures emerged for adults with RD on…

This cohort-sequential study explored the components of working memory (WM) that underlie second language (L2) reading growth in 450 children at risk and not at risk for reading disabilities (RD) whose first language is Spanish. English language learners designated as balanced and nonbalanced bilinguals with and without risk for RD in Grades 1, 2,…

The article reviews literature on the information processing model with learning disabled children. Assumptions concerning the role of automaticity, prior knowledge, and executive functioning are questioned. Also discussed are procedures for identifying common denominations, subgrouping, isolating mental components underlying academic change, and…

In three experiments on auditory free recall of words, involving 10 learning disabled (LD) and 10 nondisabled (ND) elementary students, the ND recalled more low and high cognitive effort words than LD students. Supports the hypothesis that ND and LD readers differ in processing capacity; however, cognitive effort improves results. (Authors)

Adults (ages 17-23) with childhood developmental dyslexia (CD) completed measures of phonological processing, naming speed, working memory, general knowledge, vocabulary and comprehension. Subjects scored lower than chronological age-matched adults, but were similar to reading-level matched children on most processing measures. Results suggest…

Hierarchical analysis of a test battery of sentence span, preload, and concurrent memory demand tasks was used to identify subgroups of children with different patterns of memory function. For each subgroup, performance strengths and weaknesses were related to reading, mathematics, and spelling performance. (Author/DB)

A study investigated the relationship between working memory (WM), declarative strategy knowledge, and math achievement in 111 children with and without mathematical disabilities (MD). Results found verbal and visual-spatial WM, stable verbal strategy choices, and expert strategy choices related to visual-spatial processing all contributed…

In response to articles concerning the author's earlier paper, the paper responds to criticisms concerning contextualism, the role of metatheory, distinctions between basic and applied research, cognitive components and specificity, the science of learning disabilities, neurological indices, model validation, and the nature of learning…

Investigation of the relationship between short-term memory (STM) and working memory (WM) with 75 children and adults with learning disabilities and 86 children without learning disabilities concluded that STM and WM reflect different processes, both of which seem to separate the 2 ability groups. Both STM and WM were related to reading…

A study that compared 20 children with reading difficulties (RD) with severe executive processing deficits, 16 with RD with moderate executive processing ability, 20 with high ability, and 20 who had moderate sentence span scores, found a domain-general system may partially contribute to poor working memory in children with RD. (Contains…

A study compared 84 readers with learning disabilities, chronologically age-matched and reading level-matched, for the children's working memory performance for phonological, visual-spatial, and semantic information under initial, gain, and maintenance conditions. The working memory deficits of readers with learning disabilities were hard to…

The article provides an overview of a special topical issue on information processing as it relates to learning disabilities. Components of information processing theory are described, a model of information processing is presented, and subsequent articles in the special issue are summarized. (JW)
