Typically, gender has been described by using terms such as man, woman, or even transsexual. These terms are applied to people based on their sex, or sometimes on the basis of culturally constructed characteristics. Although many people may be biologically assigned a sex, the gender they believe themselves to be may not align with this sex. An individual's gender is often assumed by outsiders based on cultural norms: outward appearance, body shape and size, physical activity, etc.. Although an individual's gender identity is determined by psychology, a gender identity can be constructed by wearing particular clothing, language, actions and such, that are associated with that gender in a given society. Psychologist and Feminist Anthropologist Anne Fausto-Sterling calls this embodiment.
