Rank-difference correlations between Memory-for-Designs test, Wechsler Intelligence Scale for Children (WISC), and Wide Range Achievement Test scores for two classes of educable mentally retarded children showed high negative correlations between Memory-for-Designs and WISC Full Scale IQs. Visual memory accounted for 84 percent of variance in…

Reviews causes of dementia in later life, especially the Alzheimer's type, its prevalence, the characteristic structural changes, and hypothesized causes. The hypothesis that Alzheimer's disease represents accelerated aging is described. Treatment issues are discussed, primarily in terms of supportive environments, differential diagnosis, and…

Two groups of undergraduates differing in reading ability were tested on a number of reaction-time tasks designed to determine the speed of encoding visual information at several different levels, tests of sensory functions, verbal and quantitative reasoning ability, short-term auditory memory span, and ability to comprehend spoken text.…

Successful and least successful fifth graders read and studied difficult or easily understood stories. For both groups, cued recall was higher on stories which made sense. Only the successful students were aware of having difficulty with the less-understandable stories, and allowed themselves more time to study them. (Author/GDC)

Studied the extent to which memory and processing speed accounted for relations between infant information processing and childhood IQ. Found that the relationship of 7-month visual recognition memory and 1-year cross-modal transfer to 11-year IQ were reduced when statistically controlled for factors derived from these measures, suggesting that…

Discusses the importance of parents' helping children to read from birth and notes the most crucial and enjoyable way is reading aloud to children. Presents six basic skills that parents can help new readers to use: getting help from pictures; remembering; sounding out the letters; expecting what comes next; writing; and making sense of content.…

A growing body of empirical and theoretical work indicates that young children (grades K-3) have difficulties solving word problems because of deficient language and text comprehension strategies. Describes a computer simulation designed to model working memory demands in "bottom-up" comprehension of arithmetic word problems, offering a…

Disorders of attention, memory, and executive function are common sequelae of traumatic brain injuries in children. Intervention usually involves externally focused interventions aimed at changing the environment to minimize the dysfunction; internally focused interventions aimed at improving the underlying cognitive ability; or compensatory…

This article presents a theory for evaluating information and communication technology design for individuals with disabilities. Simplex 1 evaluates designs in five zones: sensory and input zone; output zone; abstract working memory; long-term memory; and central executive functioning. Simplex 2 evaluates feedback, emotional responses, cognitive…

Evaluated hypothesis that cognitive antecedents of word recognition are domain-specific and unrelated to higher-order domain-general cognitive abilities in a longitudinal study of Hebrew-speaking children. Found that kindergarten domain-specific measures accounted for 33 percent of variance in Grade 1 word recognition, even after controlling for…

The relationship between modality styles and reading achievement was studied for 51 first graders given 2 subtests of the Swassing-Barbe Modality Index, 2 subtests of the Illinois Test of Psycholinguistic Abilities, and 2 tests of nonsense words. There was no significant interaction between modality preference and reading achievement. (SLD)

Whether tasks requiring the use of explicit, rather than implicit, forms of memory are sensitive to developmental and individual differences was studied using 15 non-disabled and 15 disabled third graders and 15 non-disabled and 15 disabled sixth graders. Learning disability status and grade level factors significantly affected memory performance.…

Elementary school children were asked to recall information about individuals either labeled elderly or not labeled at all. Found that children rated the elderly as unattractive, poor, sad, and sick and also had negative feelings about being old. Results suggest that children's concepts or stereotypes about the elderly affect the organization and…

Using the Mayo Older Americans Normative Studies (MOANS) group (526 55-to 97-year-old adults), factor models were examined for the Wechsler Adult Intelligence Scale-Revised (WAIS-R); the Wechsler Memory Scale (WMS); and a core battery of the WAIS-R, the WMS, and the Rey Auditory-Verbal Learning Test. (SLD)

Examines the relationships between the development of proportional reasoning strategies and three cognitive variables from Pascual-Leone's and Case's neo-Piagetian theories: (1) degree of field independence; (2) M-space; and (3) short-term storage space. Describes the ability of students to transfer problem-solving schemata to new contexts as well…
