This article synthesizes the experimental literature that compares the academic, cognitive, and behavioral performance of adults with reading disabilities to those of average-achieving adult readers. The central question posed by this review is to what extent and in what manner do adults with reading disabilities differ from adults without reading…

This study explored the contribution of the phonological and executive working memory (WM) systems to 205 (102 girls, 103 boys, 6 to 9 years old) elementary school children's fluid and crystallized intelligence. The results show that (a) a 3-factor structure (phonological short-term memory [STM], visual-spatial WM, and verbal WM) was comparable…

Twelve nondisabled adolescents were superior to 12 learning disabled students in performance on all types of strategy transformations presented on simple arithmetic computation tasks. Significant ability-group differences emerged on reduction to answer, saving partial results, unit building, and alternative method transformations. Results…

The working memory (WM) processes that underlie young children's (ages 6-8 years) mathematical precociousness were examined. A battery of tests that assessed components of WM (phonological loop, visual-spatial sketchpad, and central executive), naming speed, random generation, and fluency was administered to mathematically precocious and…

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…

This study examines whether residual recall differences between reading ability groups after a memory training task reflect the dimensions of organizational processing. Although age-related effects occurred, no ability group effects emerged, suggesting that learning disabled readers adequately access word features except when organized by…

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)

Cross-sectional and incremental age effects on cognitive processes that underlie individual differences in components of working memory (WM; phonological loop, visual-spatial sketchpad, executive processing) and mathematical problem-solving accuracy were examined in elementary school children. A battery of tests was administered that assessed…

This article synthesizes some of the published literature comparing the cognitive functioning of children with reading disabilities (RD) and children with low reading and low intelligence (low achievers). Research indicates that children with reading disabilities outperformed low achievers on measures of lexical knowledge, syntactical knowledge,…

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…

Compared to children with high-average and low-average intelligence quotients, 26 intermediate grade gifted children used fewer moves to solve a combinatorial problem-solving task and exhibited higher metacognitive knowledge on person and strategy variables. Qualitatively different intercorrelational patterns among problem-solving, metacognition,…

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…

Investigates, using eight scenarios, children making inferences about memory from incomplete knowledge and children varying in what they judge as relevant information in their schema. Showed that older children are less likely than younger ones to invoke an inferential schema when making memory judgements. (Author/BB)

Results of two experiments involving 206 upper elementary school students supported the hypothesis that less-skilled readers suffer working memory deficits that contribute to comprehension problems independent of their problems in phonological coding. Results also suggest that constraints in an executive system may contribute to reading…

Details meta-analysis of 58 intervention studies related to higher-order processing (i.e., problem solving) for adolescents with learning disabilities. Discusses factors that increased effect sizes: (1) measures of metacognition and text understanding; (2) instruction including advanced organizers, new skills, and extended practice; and (3)…
