An intensive logical and empirical critique of Herrnstein's suggestion that a state of equal social, economic, and educational opportunities in a society would inevitably produce a meritocracy based on hereditary potential for intelligence. (JM)

The mental growth patterns of 204 children were investigated on four different test occasions covering a five-year period, ages six to 11. There is no evidence of intellectual differentiation after age six nor is there a systematic decline in size of WISC subtest intercorrelations with increasing age. (Authors)

By nonintellective" are meant factors which are present in a test situation and which influence the test scores obtained but are not obviously related to the skills or knowledge ostensibly being measured by the test. (Authors)

When differences in level of motivation were controlled, all of the previously found differences between firstborn and later born disappeared. (Authors)

Argues that education, and not mere training, is what must be emphasized to give the black man a sense of something inalienably possessed, to give him personal power, and to provide a measure of survival for him today. (JM)

EEG correlates of intellectual functioning in academically handicapped and talented adolescents were investigated. Data from Ertl's Brainwave Analyzer were factor analyzed and used to predict verbal, numerical, reasoning, and spatial abilities and reading and mathematics achievement. Correlational patterns differed by group. Implications for…

Describes the origin and development of the variability hypothesis as applied to the study of social and psychological sex differences. Explores changes in the hypothesis over time, social and scientific factors that fostered its acceptance, and possible parallels between the variability hypothesis and contemporary theories of sex differences.…

Challenges Jensen's arguments (set forth in the book "Bias in Mental Testing") that intelligence tests are scientifically unbiased and that IQ and other mental tests measure something called "intelligence" by refuting Jensen's reading of the psychometric research literature. (EF)

Patterns of intellectual ability of Arab children aged 6 to 16 years were examined using the new Arab WISC-R. As in prior work, a distinct profile emerged: relative superiority in Verbal over Performance IQ's which diminished with age as a flat profile emerged in adolescence. An environmental explanation is offered. (Author/RD)

This inquiry had two aims: to assess children's ability to interpret maps in geography; to relate the assessed ability to maturity of thought as proposed by Peel, general intelligence, and age. It was found that performance on four tests depended more on intelligence than on maturity of thought or age. (Author/SJL)

The discrepancy between middle-class and lower-class children's performance on IQ tests has been thought of as "cognitive deficit" or as "cognitive differences." This paper proposes another explanation--cognitive lag hypothesis--according to which the low IQ test scores of lower-class children are seen as due to the developmentally delayed…

Although the Wechsler Intelligence Scale for Children-Revised (WISC-R) involves modifications and a complete restandardization, the literature suggests that it remains very similar in nature to its predecessor, the Wechsler Intelligence Scale for Children (WISC). Individuals perform on the WISC-R largely the same as they do on the WISC. (Author)
