We propose an "Enhanced Perceptual Functioning" model encompassing the main differences between autistic and non-autistic social and non-social perceptual processing: locally oriented visual and auditory perception, enhanced low-level discrimination, use of a more posterior network in "complex" visual tasks, enhanced perception…

The present work investigated cognitive, linguistic and narrative abilities in a group of children suffering from Duchenne Muscular Dystrophy, an allelic X-linked recessive disorder caused by mutations in the gene encoding dystrophin. The patients showed mildly reduced IQ with lower Verbal than Performance Intelligence Quotient and were mildly…

Hispanics have become the largest minority group in the United States. Hispanic children typically come from working class homes with parents who have limited English language skills and educational training. This presents challenges to psychologists who assess these children using traditional IQ tests because of the considerable verbal and…

New research on brain development has profound implications in the areas of child development and education. This review of the research describes how the brain develops to shape children's growing intelligence, addressing such questions as: (1) What are the brain's functions? (2) What are the critical or sensitive periods in brain development?…

The mental health status of African American adolescents who have been diagnosed with mild cognitive limitations was studied, and the variables that differentiated those who were well adjusted (resilient) from those who were poorly adjusted (vulnerable) are detailed in this presentation. Participating were 205 African American families, each with…

This paper reviews the literature on the intellectual abilities and performance of deaf learners within educational settings. The paper addresses such questions as whether deaf learners learn differently from hearing learners; whether deaf learners have the same intellectual capacity as hearing learners; how opinions have changed regarding the…

Current pscyhometric assessments, which are based on test score predictors providing information only on products of performance, fail to account for satisfactory amounts of variance in academic achievement or other criterion measures of interest. To corroborate and extend previous work on information processing measures, by examining the…

A study investigated previous research findings that children demonstrate certain confusions about print conventions, and that above average readers perform better on measures that assess knowledge of print conventions than do poorer readers. In addition, the study measured the contribution of intelligence to both print awareness and reading…

This document contains a series of papers which attempt to de-mystify the subject of artificial intelligence and to show how some countries in the European Community (EC) are approaching the promotion of development and application of artificial intelligence systems that can be used as an aid in vocational training programs, as well as to…

To investigate the factors determining why some children succeed at certain intellectual tasks while others of equal or near equal IQ, age, and motivation are unable to master the same task, 145 female and 144 male eighth grade students were administered "An Inventory of Piaget's Developmental Tasks" (IPDT). Labeled as concrete,…

The construction of cognitive tests is largely based on a Thurstonian model of the structure of the intellect, with test content described in terms of loadings on broad constructs called factors. Knowledge of factorial content of a test does not necessarily correspond to knowledge of mental activities elicited by test performance. Modern cognitive…

Previous studies were conducted with 14- to 15-year-old students on the nature of the processes they used to solve tasks given the incorrect/buggy/mal-rules. The computer-based Leeds Modelling System (LMS) was implemented and a database of examples, correct and incorrect, or mal-rules had been established which was sufficient to diagnose the…

Analysis of students' interpretations of a complex episode of social interaction was used to illustrate three features of human plans that distinguish them from robot plans and that form a basis for a theory of the development of social action. The features illustrated are that (1) human plans are social, (2) human plans operate on…

Witkin's Embedded Figures Test (EFT) was used to measure the changes with age in field dependence and problem-solving ability. Qualitative data concerning problem-solving strategies and quantitative data were collected. EFT was administered to 12 females in each of the following decades: 20s, 30s, 40s, 50s, 60s, 70s. All subjects were moderately…

A future, automated, interactive, knowledge delivery system for use by researchers was tested using a manual cognitive model. Conceptualized from schema/frame/script theories in cognitive psychology and artificial intelligence, this hypothetical system was simulated by two psychologists who interacted with four researchers in microbiology to…
