The human brain. Differences in male and female brain size are relative to body size. [83] Early research into the differences between male and female brains showed that male brains are, on average, larger than female brains. This research was frequently cited to support the assertion that women are less intelligent than men.
Research on biological sex differences in human psychology investigates cognitive and behavioral differences between men and women. This research employs experimental tests of cognition, which take a variety of forms. Tests focus on possible differences in areas such as IQ, spatial reasoning, aggression, emotion, and brain structure and function.
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.
In 1974, The Psychology of Sex Differences was published. It said that men and women behave more similarly than had been previously supposed. They also proposed that children have much power over what gender role they grow into, whether by choosing which parent to imitate, or doing activities such as playing with action figures or dolls.

Lesbian women and straight men have, on average, slightly larger right brain hemispheres. [126] The suprachiasmatic nucleus of the hypothalamus was found by Swaab and Hopffman to be larger in gay men than in non-gay men; [127] the suprachiasmatic nucleus is also known to be larger in men than in women. [128] [129]
Both women and men are capable of performing extraordinary feats, but there are some things the females of our species do better. Here are 7 of them, according to science. Number 7. Seeing colors ...
The term sex differences is typically applied to sexually dimorphic traits that are hypothesized to be evolved consequences of sexual selection. [38] For example, the human "sex difference" in height is a consequence of sexual selection, while the "gender difference" typically seen in head hair length (women with longer hair) is not. [39]
Contrary to common beliefs, women gave more negative scores to the concepts describing sensational objects, social and physical attractors but more positive estimations to work- and reality-related words, in comparison to men [40] This suggests that men favour concepts related to extreme experience and women favour concepts related to ...
