Sex differences in spatial visualization ability accounted for sex differences in mathematical ability for a group of college students. With spatial visualization statistically controlled, no significant sex differences in Quantitative Scholastic Aptitude Test scores were found. Males were more predictable than females due to higher spatial…

Examined the relationship between mental rotation ability and gender differences in Scholastic Aptitude Test-Math (SAT-M) performance among 760 talented preadolescents, college students, and high- and low-ability college-bound youths. Males outperformed females in both mental rotation and SAT-M for all three high-ability groups but not for the…

The purpose of this report is to distill curricular and testing implications of brain research. The report will focus on three topics. One topic is the possibility that brain lateralization--that is, the degree to which the two brain hemispheres specialize in different types of information processing--is an individual differences variable that…

Used path analysis to examine effects of spatial skill, math anxiety, and math self-confidence as mediators of gender differences in Mathematics Scholastic Aptitude Test (SAT-M) in upper third of college-bound adolescents. Found that mental rotation and math self-confidence indirectly mediated the gender-SAT-M relationship. Most of the mediational…

Examines predictor variables involved in the performance of 152 male and 143 female gifted high school juniors on the Scholastic Aptitude Test in mathematics (SAT-M). Concludes that males demonstrate greater visual-spatial ability which plays a dominant role in SAT-M performance. (FMW)

Sex differences in variability in the national norms of the Differential Aptitude Tests, Preliminary Scholastic Aptitude Test/Scholastic Aptitude Test, Wechsler Adult Intelligence Scales, and California Achievement Tests were examined. Compared to females, males were consistently more variable in quantitative reasoning, spatial visualization,…
