Sex differences in psychology

Sex differences in psychology are differences in the mental functions and behaviors of the sexes and are due to a complex interplay of biological, developmental, and cultural factors. Differences have been found in a variety of fields such as mental health, cognitive abilities, personality, emotion, sexuality, friendship,^[1] and tendency towards aggression.^[2] Such variation may be innate, learned, or both. Modern research attempts to distinguish between these causes and to analyze any ethical concerns raised. Since behavior is a result of interactions between nature and nurture, researchers are interested in investigating how biology and environment interact to produce such differences,^[3]^[4] although this is often not possible.^[4]^: 36

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 theorists take different perspectives on how much of gender is due to biological, neurochemical, and evolutionary factors (nature), or is the result of culture and socialization (nurture). This is known as the nature versus nurture debate.
