Items showing sex differences on the revised Wechsler Adult Intelligence Scale (WAIS-R) were studied. In a sample of 206 young adults (110 males and 96 females), 15 items demonstrated significant sex differences, but there was no relationship of item-specific gender content to sex differences in item performance.

Compared performance of high- and low-education adults on traditional and meaningful space and reasoning measures. Separate analyses of variance for reasoning and space revealed main effects for education and age on both abilities. Results indicated highly educated older people performed more like their younger peers. (Author/JAC)

Designed to investigate the performance of American Indian youth on the "Wechsler Intelligence Scale for Children" (WISC) compared to the "Chicago Non-Verbal" (CNV) for the purpose of establishing validity and reliability of the measurement and appraisal tools, this study analyzed test data from 71 Indian youth (aged 11 to 15)…

Magnetic resonance imaging was used to demonstrate that larger brain size (corrected for body size) was associated with higher intelligence quotient (IQ) for 40 right-handed college students grouped by high and average IQ and sex. Results suggest the relevance of brain size to intelligence test performance. (SLD)

Compared alternate forms of the Peabody Picture Vocabulary Test-Revised for (N=72) preschool children. Results indicated differences between Form L and Form M mean scores were nonsignificant for Whites, males, females, and the total group. For Black preschoolers, Form L was apparently more difficult to complete successfully than Form M. (Author)

Studied 72 children for whom the following data were available: IQ score on a conventional test (WISC or Stanford-Binet); Goodenough-Harris drawing test IQ score; and behavior description by the test administrator. Personality traits of children who performed better on either the graphic or conventional IQ test were assessed. (SJL)

Reviews developmental literature on cognitive gender differences; and compares past and present trends in gender differences, by age, from standardizations of the Wechsler Intelligence Scales and the California Achievement Tests. Decreases are found in gender differences for adolescents but not for adults. Implications are discussed. (SLD)

The investigation examined the "Wide Range Achievement Test" (WRAT) and its subtests (spelling, reading, and arithmetic), as well as possible differences attributable to the factors of sex, with the "Chicago Non-Verbal" (CNV) as a criterion variable. The 1970 study encompassed 72 Indian students (with a mean chronological age…

The Stanford-Binet: Fourth Edition and Kaufman Assessment Battery for Children were administered in counterbalanced order followed by the Cognitive Domain of the Battelle Developmental Inventory to a sample of 30 nonhandicapped, preschool children (13 males and 17 females). Correlations (corrected for restriction in range) among the three…

A written intelligence test with verbal, reasoning, and spatial subscales was administered to two comparable national samples of 1,000 thirteen-year olds in Sweden, tested in 1961 and in 1966. The increases were greater for girls than for boys, and the changes occurred simultaneously with several changes in social and educational conditions. To…

Sex differences in variability in the national norms of the Differential Aptitude Tests, Preliminary Scholastic Aptitude Test/Scholastic Aptitude Test, Wechsler Adult Intelligence Scales, and California Achievement Tests were examined. Compared to females, males were consistently more variable in quantitative reasoning, spatial visualization,…
