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.

To clarify the effects of noise, sex, and intelligence on student performance, 289 sixth-grade students were randomly assigned either the Standard Progressive Matrices (SPM) or the STEP Reading Test Form 3 (STEP III) to be taken under high- or low-noise classroom conditions, with gender and intelligence as variables. Students who took the SPM…

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. (SB)

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…

The expert-novice paradigm, which demonstrates the outstanding role of domain-specific knowledge in explaining differences in memory behavior and performance, was examined. Two studies are described which compared memory performance of groups equivalent with regard to domain-specific knowledge but differing in intellectual ability. The hypothesis…

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 was conducted to determine how the pattern of learning on an abstract concept, plate tectonics, differed between groups of different cognitive levels, sex, and intelligence quotient (IQ). The intensive time-series design was used to examine the achievement of eighth grade and ninth grade earth science students. The unique characteristic…
