Sex differences in psychology or
gender differences 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, and tendency towards
aggression. Such variation may be both
innate or
learned and is often very difficult to distinguish. Modern research attempts to distinguish between such differences, 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, although this is often not possible.
