For example, the ability to recall information better than males most likely originated from sexual selective pressures on females during competition with other females in mate selection. Recognition of social cues was an advantageous characteristic, because it ultimately maximized offspring and was therefore selected for during evolution.
A 2022 meta-analysis found that even small sex-based differences in general intelligence were an artifact of older tests, with current test batteries showing no statistically significant difference between the sexes, but that differences in intelligence sub-types such as processing speed (favoring females) and visual-spatial reasoning (favoring ...
A number of factors combine to influence the development of sex differences, including genetics and epigenetics; [5] differences in brain structure and function; [6] hormones, [7] and socialization. [3] [4] [8] [page needed] The formation of gender is controversial in many scientific fields, including psychology. Specifically, researchers and ...
The 21st century has witnessed a resurgence of research on gender differences in variability, with most of the emphasis on humans. The results vary based on the type of problem, but some recent studies have found that the variability hypothesis is true for parts of IQ tests, with more men falling at the extremes of the distribution.
For example, certain autoimmune diseases may occur predominantly in one sex, for unknown reasons. 90% of primary biliary cirrhosis cases are women, whereas primary sclerosing cholangitis is more common in men. Gender-based medicine, also called "gender medicine", is the field of medicine that studies the biological and physiological differences ...
It has been suggested that sexual selection played a part in the evolution of the anatomically modern human brain, i.e. the structures responsible for social intelligence underwent positive selection as a sexual ornamentation to be used in courtship rather than for survival itself, [4] and that it has developed in ways outlined by Ronald Fisher ...
The great apes (Hominidae) show some cognitive and empathic abilities. Chimpanzees can make tools and use them to acquire foods and for social displays; they have mildly complex hunting strategies requiring cooperation, influence and rank; they are status conscious, manipulative and capable of deception; they can learn to use symbols and understand aspects of human language including some ...
For example, he says that better empathising may improve care of children, and that better empathy may also improve women's social network which may help in various ways with the caring of children. On the other hand, he says that systemising may help males become good hunters and increase their social status by improving spatial navigation and ...
