Tests focus on possible differences in areas such as IQ, spatial reasoning, aggression, emotion, and brain structure and function.
Human adults and children show many psychological and behavioral sex differences. Some (e.g. dress) are learned and cultural. Others are demonstrable across cultures and have both biological and learned determinants.

Researchers further analyzed the differences in brain volume, surface area and cortical thickness by testing the men and women on verbal-numerical reasoning and reaction time in separate groups. It was found that the group of men slightly outperformed the women in both the verbal-numerical reasoning and reaction time tests.
