Sex difference in perceptual-verbal ability in relation to body size.

摘要

Sex difference in verbal ability was reconsidered in relation to body size. The perceptual-verbal ability (PVA) was assessed using the A's Test. For the raw data, women excelled men, as expected. PVA positively correlated with height and weight of the subjects, but only for women. As a covariate of height, sex difference increased by increasing the women's score; men's score did not change. Tall women had much higher scores than short men. It was concluded that sex difference in PVA is stable despite the smaller body size of females than males, and body height may be predictive for this ability, but only in women.
