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.
The human brain. Differences in male and female brain size are relative to body size. [85] 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.
Though statistically there are sex differences in white matter and gray matter percentage, this ratio is directly related to brain size, and some [22] argue these sex differences in gray and white matter percentage are caused by the average size difference between men and women. Others argue that these differences partly remain after ...
The development of sexual differences begins with the XY sex-determination system that is present in humans, and complex mechanisms are responsible for the development of the phenotypic differences between male and female humans from an undifferentiated zygote. [3]
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 ...
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.

A proposed evolutionary hypothesis is that men and women evolved different mental abilities to adapt to their different roles, including labor-based roles, in society. [50] For example, "ancestral women more often foraged for fruits, vegetables, and roots over large geographic regions."
Sex differences in semantic memory have also been found with a higher female ability which can be explained by a female advantage in verbal fluency. [19] One other study also found greater female free-recall among the ages 5–17. [20] In another study, when using multiple tests for episodic memory, there were no differences between men and ...
