Patterns of memory dysfunction were determined in 50 middle school learning disabled readers (LD) through a hierarchical cluster analysis. Results were consistent with memory capacity theories of LD and provided external validation for classification of LD readers on psychometric measures according to patterns of memory performance. (Author/DB)

Thirty-five learning-disabled readers (mean age 10) and 43 controls were compared on a sentence span task and on recall of everyday features, consequential events, and misleading information. Results indicated that subjects were deficient on working memory and naturalistic measures, but their naturalistic memory deficits did not appear to relate…

Sixteen skilled and 16 learning disabled (LD) readers (ages 11-12) viewed nonsense pictures either without names, with names that emphasized the semantic aspects of the picture, or with names unassociated with the pictorial representation. Results suggested that semantic coding deficits in LD readers were localized to retrieval processes.…

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,…

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…

Learning-disabled and average readers (n=120) from grades four through six completed comprehension questions under one of four treatment conditions. Results indicated that computer-mediated text was no better than off-line conditions in improving learning-disabled readers' comprehension. Attribution and metacognitive sophistication were…

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…

Examined relationship between components of vigilance and differences in verbal intelligence in children (N=63) in grades 5-7. Found a number of significant correlations between measures of vigilance and intelligence, as well as achievement. (Author/ABL)

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)

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)

Whether high levels of metacognitive knowledge about problem solving can compensate for low overall aptitude was studied for 31 high-aptitude and 25 low-aptitude children in grades 4 and 5. Results confirming superior performance of high metacognitive individuals are discussed in terms of the independence of metacognition and academic aptitude.…
