Hierarchical analysis of a test battery of sentence span, preload, and concurrent memory demand tasks was used to identify subgroups of children with different patterns of memory function. For each subgroup, performance strengths and weaknesses were related to reading, mathematics, and spelling performance. (Author/DB)

A study investigated the relationship between working memory (WM), declarative strategy knowledge, and math achievement in 111 children with and without mathematical disabilities (MD). Results found verbal and visual-spatial WM, stable verbal strategy choices, and expert strategy choices related to visual-spatial processing all contributed…

The information processing approach to the assessment of learning disabled students' intellectual performance includes decisions about: (1) relationship between hypothesis testing and overall performance, (2) the knowledge base for strategy development, (3) coordination of search strategies, (4) metacognition, and (5) problem solving strategies.…

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…

In response to articles concerning the author's earlier paper, the paper responds to criticisms concerning contextualism, the role of metatheory, distinctions between basic and applied research, cognitive components and specificity, the science of learning disabilities, neurological indices, model validation, and the nature of learning…

Three experiments exploring the relationship of cognitive effort to the differences in word recall between skilled and learning disabled readers are described. Results suggest the amount of cognitive effort that can be effectively expended to produce a distinctive memory trace is related to individual differences in attentional capacity.…

An investigation of effects of information processing models on instruction showed that strategy and metacognitive instruction is infrequent in teacher-child interactions; a behavioral paradigm captures most teacher-child interactions; what teachers say and do is discrepant; and content of teacher-child verbal behavior varies minimally between…

Correlations between phonological, orthographic, semantic, metacognitive, and working memory measures were studied for 40 learning-disabled students and 40 skilled readers ages 8 to 12. Results suggest that the cognitive processes that contribute to reading deficits are best understood in the context of their combination with other operations.…

Examines, in two experiments, the memory coding processes of readers during reading of connected text. Finds that, along with phonological coding, semantic processing contributes an important amount of variance to deficiencies in the reading of connected text. (RS)

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…

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…

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…

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)
