The influence of spatial ability on gender differences in mathematics college entrance test scores across diverse samples.

The relationship between mental rotation ability and gender differences in Scholastic Aptitude Test-Math (SAT-M) across diverse samples was investigated. Talented preadolescents, college students, and high- and low-ability college-bound youths, totaling 760, were administered the Vandenberg Mental Rotation Test. Gender comparisons showed male outperforming female students in both mental rotation and SAT-M for all 3 high-ability groups but not for the low-ability group. For all female samples, mental rotation predicted math aptitude even when SAT-Verbal was entered first into the regression. For male samples, the relationship varied as a function of sample. When mental rotation ability was statistically adjusted for, the significant gender difference in SAT-M was eliminated for the college sample and the high-ability college-bound students. This suggests that spatial ability may be responsible in part for mediating gender differences in math aptitude among these groups.
