Hong Kong Chinese and American adolescents were given three Piagetian tasks of formal operations in order to assess cultural, age, and sex differences. Significant effects were demonstrated with Americans, older subjects, and males performing at more advanced levels. (Author/JMB)

Examined association of individual differences in physical maturation with information-processing speed among 9- and 10-year olds. Found that early maturers were faster than late matureres, although this maturity effect was primarily the result of a significant effect for boys. The early maturers' faster processing times may be specific to boys or…

The authors are emmersed in a comprehensive review of the literature on intellectual sex differences. This paper consists of the first progress report and the tentative hypotheses of the work completed so far. Discussion is initially concerned with verbal and spatial abilities. It is concluded that girls learn language earlier, and may continue to…

Investigated linkage between delay-of-gratification dimension of impulsivity and social information processing in 80 second-graders and 80 fifth-graders. Found that low-delay ability and younger participants made less use of social cues than did older and high-delay ability participants; however, these findings were qualified by grade and gender…

This study investigates the development of multiplicative classification skills in lower class black and middle class white children on tasks which contain either three-dimensional objects or two-dimensional pictorial representations of the same objects. Multiplicative classification refers to the simultaneous classification of objects into two or…

High verbal subjects were much faster than low verbal subjects in making taxonomic category identity matches and homophone identity matches. High verbals were also faster in making physical identity matches. Males did not differ from females in the time required for any matching tasks; however, they made slightly more errors. (Author/MV)

An extensive literature review of the cross-cultural generalizability of the concepts derived from differentiation theory which focuses on the major proposition of the theory and its primary empirical expectations. Studies conducted in other cultural settings which were either guided by the theory or sought to evaluate it are discussed and…

Most definitions and training of assertive behavior fail to consider cultural diversity in social skills. Verbal, nonverbal and cognitive components of assertive behavior were investigated to determine cultural variations in assertiveness. Black (N=30) and white (N=30) male and female college students enacted 16 role-play scenes with 4 role…

This quantitative study of imagery in 96 undergraduates addresses the problem of individual differences in the characteristics of mental imagery workspaces. A 20-item questionnaire embodying nine characteristics of mental imagery workspaces was administered to 78 females and 18 males. Analysis of variance by gender disclosed significant higher…

The present findings suggest that never" as a response and very often" as a response are mediated by different underlying processes, at least between the ages of 8 and 17. (Author/WY)

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.…

In a test of cognitive consistency across cultures, balance scores showed significant differences between Greek and American subjects and between males and females in both cultures, differential across tasks. Implications for consistency theory in general are discussed. (Author/EH)

Two processing abilities used to solve spatial problems are examined: (1) the analog ability of structural visualization; and (2) the non-analog ability of verbal analytic reasoning. The distinction is based on an evaluation of information processing theory and a review of process-oriented studies of individual differences. Criteria are presented…
