This study investigates the relationships of domain-general cognitive abilities and domain-specific verbal and mathematical abilities to students' educational characteristics when two theoretically grounded, but competing structural models are applied. In the standard model, a single latent ability causes interindividual differences in the…

This study found that 10 adolescents with mental retardation processed stimuli varying with respect to symmetry in comparable manner to peers matched for mental age and chronological age. Results argue for the robustness of the symmetry effect across groups differing in intelligence and physically dissimilar stimulus types (checkerboard versus…

Examines the contiguity of siblings within family structure--a concept reflecting how much of the family environment siblings share with one another--in relation to within family IQ scores. Results fail to demonstrate family structure effects. (HOD)

Comparison of the mental status of 30 subjects with Down's Syndrome mosaicism and 30 matched subjects with trisomy 21 Down's Syndrome found that the mean intelligent quotient of the mosaic Down's Syndrome group was significantly higher and that this group showed better verbal abilities and more normal visual-perceptual skills.

Examines the perceptions of Israeli college students toward the modal intelligence of and social distances among the following groups: (1) European Jews; (2) Eastern Jews; (3) Christian Arabs; (4) Moslem Arabs; and (5) Druze. Concludes that perceptions are molded by and function like cultural group stereotypes. (FMW)

This paper examines the implications of recent theory and research in cognitive psychology for the understanding and assessment of intelligence. Three major themes are developed. The first has to do with how changes in the social and educational climate for testing can influence the conception of intellectual compentence and the technology of…

Thorndike's Stanford-Binet data suggest that from 1932 to 1971-72 preschool children enjoyed greater IQ gains than older children, possibly due to the rise of television. Additional analysis indicated that gains were either due to sampling error or totally antedated 1947. Gains of 12 IQ points were found for Americans. (Author/EGS)

Word recognition data from identical and fraternal twins and siblings (N=172) indicated that the phonological coding deficit of children with reading disabilities was highly heritable. Orthographic coding was not significantly heritable. Poor readers with low IQs were superior to similar reading but average IQ readers in phonological coding.…

Reports that no significant difference in reliability appeared between a heterogeneous and a homogeneous form of the same general science matching-item test administered to 316 sixth-grade students but that scores on the heterogeneous form of the test were higher, independent of the examinee's sex or intelligence.

Describes a new theory of multiple intelligences (MI) that identifies seven relatively independent forms of information processing that individuals exhibit in differing patterns. Describes the following MI-related educational research projects: (1) Arts PROPEL; (2) the Key School project; and (3) Project Spectrum. (FMW)

Data from the Japanese standardization of the Wechsler Preschool and Primary Scale for Intelligence were used to analyze the structure of abilities of Japanese children in terms of the Burt-Vernon hierarchical model of intelligence. It was suggested that the pattern of cognitive strengths and weaknesses that emerged would help clarify a number of…

Investigates factors, including heredity and culture, contributing to exceptional Asian American academic achievement. Proposes the concept of relative functionalism, under which Asian Americans perceive and have experienced restrictions in upward mobility in occupations unrelated to education. Consequently, educational achievement assumes…

This study of 640 twins with reading disability and 436 controls (mean age 12) examined external validity of the distinction between specific reading retardation and reading backwardness, in 3 domains: genetic etiology, sex ratio and clinical correlates, and neuropsychological profiles. There was no evidence of differential genetic etiology of the…

Reviews data from the "High School and Beyond" study to examine sibling intellectual symmetry and the degree to which family background affects the siblings' intellectual ability. Finds considerable symmetry in intellectual skills. Discovers little impact on symmetry from gender or birth order. (CFR)

Maintains that intellectual ability has become a more important determinant of occupational success in recent decades, resulting in increased social class differences. Finds that, contrary to the usual view, class differences have become smaller and current social problems cannot be ascribed to low-ability people in the lower classes. (CFR)
