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…

Fifty-five males with learning disabilities and 55 average-achieving males in grades 6-7 studied paired associates of varying difficulty levels, through image construction or pairing rehearsal. Regardless of item type or presentation rate, both groups of students benefited from imagery instructions, with great similarity in between-condition…

Whether software-based mediated instruction reduces the incidence of misconceptions and errors by children learning the LOGO computer language was studied with 24 fourth and 46 second graders. Mediated instruction reduced errors and misconceptions compared to those detected in prior studies. The roles of working memory and true misunderstandings…

Discusses the failure of early childhood education to meet the needs of boys. Describes developmental differences between boys and girls, and teacher attitudes towards boys. Suggests actions relating to environment, teacher training, hiring, evaluation, and activities that will meet the needs of boys. Lists characteristics of good early childhood…

A multivariate hierarchical model of specific cognitive abilities was fitted to data from 196 adopted and 213 nonadopted children from the Colorado Adoption Project and 120 of their siblings to assess genetic influence on specific mental abilities. Genetic effects occur in middle childhood that differentially influence mental ability scores.…

Seven chapters consider what learning is and what counts as learning in the context of formal schooling. How qualitative research assists in this examination is explored. Qualitative research is an indispensable tool in the repertoire of research approaches that will illuminate learning discourse. (SLD)

This study, involving 24 young and elderly normal-hearing adults, addressed the effects of aging on auditory serial-recall performance for natural and synthetic words. Serial recall of monosyllabic words was not affected by age per se or by rate of presentation, but word difficulty affected recall for both groups. (Author/JDD)

Two cohorts of preschool children (n=238) were followed to determine whether tests of phonological awareness, orthographic processing, and serial-naming speed, added to a preschool battery, would improve prediction of reading. The major predictors of first-grade reading and spelling were preschool letter-naming and sentence memory for both…

Studied the imitation behavior of thirty 14- to 18-month-olds using peer and adult models in an elicited imitation paradigm. Indicated significant memory for 3-step behavior sequences both immediately after modeling and 1 week later compared with baseline performance. Found that children in the peer model group outperformed children in the adult…
