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 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…

Three studies of college students found a sex difference in the correlation of memory scanning rate, short- and long-term components of free recall, and word recognition with memory span. Findings are discussed in terms of prior work and a theory presented to account for the obtained sex differences. (Author/RD)

Various hypotheses and opinions relating to cognitive differences between males and females are reviewed. It is shown that the largest sources of cognitive differences between the sexes can be traced to courses of study and other aspects of relevant experience based on outmoded sex role stereotypes.

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 study was conducted to determine how the pattern of learning on an abstract concept, plate tectonics, differed between groups of different cognitive levels, sex, and intelligence quotient (IQ). The intensive time-series design was used to examine the achievement of eighth grade and ninth grade earth science students. The unique characteristic…

The concurrent and discriminant validity of La Prueba de Analisis Auditivo, a Spanish auditory perception test, and the validity of the perceptual deficit hypothesis and of hypotheses derived from verbal processing theory were evaluated in a sample of 114 second-grade Hispanic pupils receiving reading instruction in Spanish. (Author/BW)

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)

This study was undertaken to determine the cognitive preference orientation (measured by the Cognitive Preference Examination II) and Jungian personality types (measured by the Myers Briggs Type Indicator, MBTI) of 283 eighth-grade students. Relationships between these two variables were predicted. It was hypothesized that introverted, intuitive…

To investigate the interrelationships between creativity and seven variables, 74 students in grades 4 through 8 plus the vocational group at a school for the deaf were tested. In addition to creativity, subjects were tested for intelligence, academic achievement, imaginative productions, perception by teachers, self-evaluation career aspirations,…

Problem solving flexibility (PSF), an ability commonly assessed in creativity batteries, was studied in a sample of middle class children (grades 1 through 3, average IQ 114), tested on questions resembling Guilford's consequences procedure. An hypothesis linking PSF with alertness to and interest in the environment was generally supported, more…

This paper deals with the issue of black-white differences in cognitive skills. Some authorities attribute these differences to differences in the environments of black and white homes. Others state that the differences are due to differences in genes, i.e., heredity. Scholars holding these two opposing views have become more or less entangled in…

Adolescents, ages 11-12 and 13-14, were tested for maturity of judgment about stability-change situations and about time perspective. (CP)
