Biological limits of gender construction

A biosocial theory of gender is constructed on both the macro and micro lev els. A micro-model of within-sex differences among females integrates the b iological model current in primatology with the prevailing social science m odel. It shows how sex differences in hormone experience from gestation to adulthood shape gendered behavior (that is, behavior that differs by sex). On the macro level, this model also illustrates how socialization and envir onment shape gendered behavior. It then demonstrates how hormone experience s can facilitate or dampen the effects of socialization and environment on gendered behavior. Data are from a sample of women who were studied from be fore they were born to the end of their third decade. I speculate about the constraints placed by biology on the social reconstruction of gender.
