When a battery of tests commonly associated with intelligence was administered to 144 13 year olds identified as extremely precocious, the verbally precocious students scored higher on verbal and general knowledge types of tests, and mathematically precocious students scored higher on tests of nonverbal reasoning, spatial ability, and memory.…

Delineates the current consensus regarding the nature and the development of intellectual ability. Examines when one would expect general abilities to moderate the relationship among domain-specific and other processes. Reviews recent studies in which general abilities were used as independent variables or covariates. Suggests that generally,…

Argues that Herrnstein and Murray's "The Bell Curve" (1994) merely restates the notion that intelligence can be reduced to a single ordinal measure, i.e., the primary factor for determining group or individual social-class status. Evidence from the biological sciences and quantitative genetics is presented that reveals that social…

There is evidence that IQ tends to be higher in those who were heavier at birth or who grew taller in childhood and adolescence. Although these findings imply that growth in both foetal and postnatal life influences cognitive performance, little is known about the relative importance of brain growth during different periods of development. We…

The two-level theory of mental abilities posits two broad classes of ability: level I (learning and memory) and level II (the "g" factor of intelligence tests, reasoning, abstraction, and problem solving). Levels I and II are hypothesized to interact with SES and/or race such that: (l) SES differences are greater for level II than for I,…

A reanalysis of Stephens' intercorrelations of Wechsler subtests, achievement tests, and Piagetian tasks was conducted. (EJ 055 112) Piagetian tasks contributed almost equally to the definition of the general factor in intelligence along with the Wechsler subtests and the achievement tests. Communality outweighed differences between intelligence…

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 revised version of this monograph serves two purposes: (1) to describe what the Wechsler Intelligence Scale for Children-Revised (WISC-R) measures with regard to reading/learning disability in the light of current findings, and (2) to summarize research with the Wechsler Intelligence Scale for Children (WISC) and WISC-R as related to…

Adverse effects of material rewards on Wechsler subscale performance may be the result of a reward-produced developmental regression. To further explore that idea through replicating earlier findings with adults, and to extend the enquiry to children, selected Wechsler subscales were administered to 32 subjects at each of three ages (5, 10, and 18…

Effects of heterogeneous and homogeneous grouping on the psychological functioning of Mexican American preschool children from economically disadvantaged families were investigated in a pilot project at San Jose State College Child Laboratory. Three experimental groups were composed of (1) 9 Mexican American children from low-income families and 9…

This study examined the effects of teacher expectancy on changes in intelligence, known as the phenomenon of the self-fulfilling prophecy. Differences in sex, socioeconomic status, and teacher opinion about standardized tests were control factors. The teachers completed a questionnaire that provided the basis for classifying teachers into high,…

Certain concepts that are sometimes confused in discussions on testing socially disadvantaged children are clarified and a history of testing, beginning with Binet, is presented. Finally, five problems in using tests to evaluate educational programs for the disadvantaged are considered. (AG)

The multiple intelligence theory is based on cultural contexts, biological analysis, developmental theories, and a vertical theory of faculties. Seven intelligences are identified: linguistic, logical mathematical, musical, spatial, bodily kinesthetic, interpersonal, and intrapersonal. The theory's educational implications are described,…
