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…

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)

Examines, in 9- and 12-year-olds, two theories of disabled readers' memory deficiencies. Subjects were compared on diotic and dichotic listening tasks for recall of semantically organized, phonemically organized, and categorically unrelated wordlists. Dependent measures included free recall, serial recall, recall organization, and hierarchical…

This study explored relationship between working memory (WM) and mathematical problem solving, comparing children with learning disabilities (LD) to chronologically age-matched and younger achievement-matched children on measures of WM, phonological processing, problem-solving, and word problem-solving accuracy. Found support for notion that…

Investigated how working memory differences between learning-disabled and nondisabled children reflect a specific or generalized deficit and whether limitations in enhancement of learning-disabled student's working memory performance are attributable to process or storage functions. Results suggest that learning-disabled suffer generalized working…

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…

Investigates the extent to which learning disabled readers' atypical encoding relates to their deficiencies in semantic memory by comparing learning disabled and nondisabled readers in two age groups on dichotic listening tasks that included orienting and nonorienting instructions. (HOD)

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.…

Results from a study involving 32 learning-disabled, 17 gifted, and 14 normally achieving students from grades 4 and 5 support the idea that learning-disabled children's problem-solving performance reflects a weak integration of metacognitive skills with online processing and problem solution. (SLD)

The differences between learning disabled (LD) and non-LD children's problem-solving protocols were analyzed during a picture arrangement task. Although the groups of 29 LD and 27 non-LD children were comparable in global mental processing and task performance, LD children had difficulty with representing problems and deleting irrelevant…
