This study provides a meta-analysis of the correlational literature on measures of phonological awareness, rapid naming, reading, and related abilities. Correlations (N = 2,257) were corrected for sample size, restriction in range, and attenuation from 49 independent samples. Correlations between phonological awareness (PA) and rapid naming (RAN)…

The Continuous Performance Test was administered to 16 normal and 16 learning disabled males (CA 12.5) to test the proposition that learning disabled children manifest an attention deficit related to reading performance. (Author)

The influence of cognitive growth in working memory (WM) on mathematical problem solution accuracy was examined in elementary school children (N = 353) at risk and not at risk for serious math problem solving difficulties. A battery of tests was administered that assessed problem solving, achievement, and cognitive processing (WM, inhibition,…

Investigated whether limitations in the enhancement of learning-disabled readers' working memory (WM) performance are attributable to process or storage functions. Found that: intercorrelations among diverse WP measures increased on demanding conditions; and verbal WM was not directly related to reading skill, supporting the notion that poor…

This investigation explored the relationship between short-term memory (STM), working memory (WM), and reading proficiency among adolescents (n=30) with learning disabilities. Results suggest that reading models which focus on STM or WM in isolation do not adequately capture the reading performance of the students. Models that coordinate STM and…

The purpose of this study was to determine the components of working memory (WM) that underlie less skilled readers' comprehension and word recognition difficulties. Performance of 3 less skilled reading subgroups--children with reading disabilities (RD) in both word recognition and comprehension; children with comprehension deficits only; and…

Investigated the contribution of two working-memory systems (the articulatory loop and the central executive) to the performance differences between learning-disabled and skilled readers. Found that, compared to skilled readers, learning-disabled readers experienced constraints in the articulatory and long-term memory system, and suffered…

This study examined the way successful college students with LD compensated for their deficits in phonological processing. Successful was defined as average or above-average grades in college coursework. The study compared the cognitive and metacognitive performance of students with and without LD (N = 40). Although achievement levels for both…

Three experiments involving 85 learning-disabled (LD) children and 101 non-LD children investigated whether memory difficulties of LD children may be attributable in part to executive processing. Results suggest that LD readers may suffer from executive processing deficiencies, although they do not rule out effects of language-specific processes.…

This study identified cognitive processes that underlie individual differences in working memory (WM) and mathematical problem-solution accuracy in elementary school children at risk and not at risk for serious math difficulties (SMD). A battery of tests was administered that assessed problem solving, achievement, and cognitive processing in…

Fifth-grade learning disabled and skilled readers (N=32) were compared on verbal dichotic listening tasks for free recall and cued recall of word lists organized by semantic, phonemic, and structural features. Results indicated that disabled readers were comparable on free recall but were inferior to skilled readers on cued recall. (Author/JW)

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…

Two experiments involving 227 children aged 5 to 18 years suggest that working memory operates as a general system independent of the subject's reading skill and that dynamic testing procedures enhance predictions of reading performance. Individual differences in working memory do not appear restricted to an academic domain. (SLD)

Models of working memory were compared in 2 experiments as means of explaining variance in the comprehension of 95 skilled and 80 learning-disabled readers from grades 4 through 7. Results suggest that learning-disabled children's working memory problems are functionally related to higher order processes and not memory alone. (SLD)
