Document Summary
Twin studies used to analyze genetic similarities/differences. Chemicals produced by endocrine system that circulate throughout the body. Girls more aggressive, active, less likely to play with female toys. Does not seem to be associated with gender identity problems. Testosterone linked to frustration, impatience, impulsivity, high levels of physical. Factors such as competition and threat to social status may evoke biological activity, etc. that response. Lateralization localization of an ability (e. g. language) in one hemisphere of the brain. Effects of prenatal hormones on gender-role behaviour are stronger among girls than boys. Most studies do not find sex difference in brain lateralization, but among ones that do, men appear to be more lateralized than women. Males/females may use different strategies to achieve the same outcome. Sex difference n the brain does not always lead to a sex difference in behaviour. Nature and nurture are not two mutually exclusive categories, but categories that interact with one another.
