Studied sex differences in general intelligence in 10,475 adults taking cognitive test batteries. Results suggest a negligible difference in general intelligence, a finding consistent with findings from quite different test batteries and subject samples. (SLD)

Findings showed an almost even percentage of boys and girls, that more girls had fathers with doctorate degrees, that girls' arithmetic and spatial abilities were not significantly different from boys', that girls increased or decreased in IQ more than boys in high school, and that boys' IQs and grade point averages were significantly correlated…

This book contains papers that discuss the "g factor" (general intellectual capacity) in discerning intelligence and how to influence the development of intelligence. The g factor relates to the theory that individuals who do well on one mental ability test tend to do well on other mental ability tests due to an innate ability. Chapters…

Studied the influence of task content and sex on the relationship between intelligence and cortical activation in 26 males and 25 females administered verbal, numerical, and figural versions of an elementary cognitive task. Results suggest comparatively lower cortical activation in more intelligent individuals, but the pattern interacted with sex…

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)

Using 72 lower class children, concurrent validity of the WPPSI was studied using the Stanford-Binet as the criterion. Correlations between SB and WPPSI were moderately high. Among the WPPSI subtests, Vocabulary was significantly lower than all other subtests. The only significant sexual difference favored females on Similarities. (Author)

IN THE LONGITUDINAL BERKELEY GROWTH STUDY, SUBJECTS WERE TESTED AT 16, 18, 21, AND 26 YEARS ON THE WECHSLER-BELLEVUE, AND AT 36 YEARS ON THE WECHSLER ADULT INTELLIGENCE SCALE, WHICH CONTAIN BOTH VERBAL AND NON-VERBAL SUBSCALES. THE MOST CONSISTENT INCREASES IN MEAN SCORES OVER THE PERIOD WERE IN INFORMATION, VOCABULARY, AND COMPREHENSION. DIGIT…

How boys and girls qualify for programs for gifted students using the Wechsler scales of intelligence was studied. The scores that most often qualify them and differences among those scores were studied. The Wechsler Intelligence Scale for Children-Revised (WISC-R) was used with a random sample of 120 children (60 girls and 60 boys) chosen from…

Two studies examined differences in intellectual ability associated with masculinity and femininity in high school and college students. Available from: Ablex Publishing Corporation, 355 Chestnut Street, Norwood, New Jersey 07648. (CL)

Forty college students were administered a self-rating scale for intelligence along with several actual ability measures, including the Concept Mastery Test and "breadth" and "depth" indices based on the Weschsler Adult Intelligence Scale Similarities subtest. (MS)

This report gives estimates of the intellectual maturity based on the Goodenough-Harris Drawing Test (GHDT). The data were collected in Cycle III of the Health Examination Survey of noninstitutionalized U.S. youths during 1966-70. The GHDT instructions were modified for use in the survey to require each youth to draw two figures--a…

Analysis of the mental factors of seventh grade students indicates that numerical facility and perceptual speed are a single factor at this age level and that no purely verbal factor exists. Seven clearly differentiated factors are found for males and five for females. (Author/WY)

The six Holland-based Interest Scale scores yielded by the Harrington-O'Shea Career Decision-Making System (CDM) (T. Harrington and A. O'Shea, 1982) were related to sex, race, and performance on the Kaufman Adolescent and Adult Intelligence Test for 254 adolescents and young adults. CDM scores did not relate to most of the variables studied, and…

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…
