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…

Explored the contribution of two working memory systems, the articulatory loop and the central executive, and short-term memory to the word recognition and comprehension deficits of children with learning disabilities. Results of 2 experiments with 150 children support the idea that poor word recognition and comprehension reflect deficits in a…

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.…

Reaction time and movement time were negatively and moderately-to-strongly correlated with Ravens matrices performance and with reading comprehension and performance on the California Test of Basic Skills for 20 ninth-grade girls. Weaker relationships were found for mathematics and English grades, although the direction was consistently negative.…

A correlation exists between verbal ability test scores and name identity minus physical identity reaction times in a letter matching task. The present results support Carroll's (1981) suggestion that the reaction time difference is related more to speed than power component of standardized tests and is not optimum for prediction.
