The Performance Scale of the Wechsler Adult Intelligence Scale-Revised was administered to 185 hearing-impaired young adults. A gender difference was found only on the Digit Symbol subtest, where females outperformed males. The high degree of factorial similarity between males and females indicated that the underlying construct being measured does…

WISC-III scores of 233 students (ages 9 to 13) with mental retardation were examined. Boys had higher Full Scale, Verbal, and Performance IQs than did girls. Boys also had higher scores on six of the 10 subtests. In addition, all of the statistically significant differences were in favor of boys. (Author/CR)

This report summarizes the results of the administration of the vocabulary and Block Design subtests of the WISC to a national probability sample of noninstitutionalized youths 12 through 17 years of age. Information is presented on the derivation of percentile equivalents, normalized scale scores, and a short-form estimate of Face Scale Scores.…

Groups of 270 Black and 270 White children drawn from the national stratified random sample used in the standardization of the Wechsler Intelligence Scale for Children-Revised (WISC-R) were matched on age, sex, and WISC-R Full-Scale Intelligence Quotient to facilitate investigation of the patterns of specific cognitive abilities.

WISC-III IQs and subtest scaled scores of 440 students with specific learning disabilities were examined for gender differences. Boys exhibited statistically higher Full Scale, Verbal, and Performance IQs than did girls, as well as higher scores on six of seven subtests. Girls outperformed boys only on the Coding subtest. (Author/CR)

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…

Reviews relationship of IQ scores to race and gender. Explores the logic that supports the use of intelligence testing to discriminate and to exclude. Argues that default assumptions allow researchers to remain unaware of the subtle adverse impact of their research. Includes recommendations to encourage a broader understanding of intelligence.…

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…

Intelligence quotients from the Slosson Intelligence Test for 60 Head Start children drawn from three areas of metropolitan St. Louis showed the group to be heterogeneous with respect to intelligence. No significant differences were associated with sex or race. Consideration of such characteristics is needed in planning school programs. (Author/CM)

Scatter on the revised Wechsler Intelligence Scale for children (WISC-R) was evaluated for 105 learning disabled (LD) children. Scatter was defined as range of scaled scores on: (1) five regular verbal tests; (2) five regular performance tests; and (3) all 10 regular subtests. Pairwise combinations of 11 subtests were also evaluated for deviations…

This study investigates the effect of socio-economic level (lower and upper-middle), race (black and white), and sex on locus of control of reinforcement scores, and the relationship between the latter scores and reading achievement in a sample of 211 second grade children. A stratified random sampling technique insured adequate levels of each…

While debates over the heritability of IQ and the potential for culture bias in measuring instruments have generated much research and public comment, it is also possible to investigate the significance of interracial differences in mean IQ by ignoring both the foregoing issues and instead examining the social psychology of the test situation…

The purpose of the study was to compare the performances of black and white urban high school students on a conventional measure of intelligence, the Lorge Thorndike vocabulary test and a culture specific test, the Black Intelligence Test of Cultural Homogeneity. In addition to determining whether or not there were race differences in performance…

Students of high intellectual ability and their parents were tested on a battery of cognitive tests. Vernon's model of intelligence best fit results. A verbal-educational and a practical-spatial-mechanical factor explained most performance variance. Among children, age related to verbal but not spatial or mechanical abilities. (Author/RD)

Cattell; "Theory of Intelligence," L. G. Humphreys; "Using Measured Intelligence Intelligently," P. R. Merrifield; "Intelligence: Definition, Theory, and…
