In psychological terms, when we talk about gender roles, we mean the expected behaviors society has for men and women, according to their own nature. Men have to behave this way and act like men. Women have to behave that way and act like women.
Gender typing is how both genders acquire their traditional roles in society, according to their genders. Gender identity refers to our own sense of being masculine or feminine and is the result of our own personality or perspective. Gender schema is the way boys and girls adjust their behavior according to established gender roles in society. The term is relatively modern and was established in 1981 by Psychologist Sandra Bem.
