What is gender psychology?

Gender psychology is the study of the behaviors and roles
that are acquired by individuals under the premise that males and females will, in fact,
behave in different ways because of their sexual roles as males or
females.

However, aside from the study of the behaviors of
males and females, gender psychology extends to the study of the behaviors of
individuals who assume the roles and behaviors of a gender opposite to their own, for
example, individuals who identify themselves as  transgendered, bisexual, homosexual,or
any other gender-based identity.

Gender psychology includes
the gender schema theory as a topic of study. This theory states that nurture plays an
influential factor in the sexual identification of boys and girls. According to this
paradigm, boys and girls "learn" to act like boys and girls, respectively, as they learn
those behaviors from other kids, and as they get molded by their parents to become "all
boys" or "all girls".

However, what happens when nurture is
not enough, no matter how strongly the gender-appropriate behaviors are imposed? What if
a male child, raised by a masculine and heterosexual male, still grows up to discover
that he has homosexual tendencies OR effeminate mannerisms: Who is to say that there is
something wrong? Is it nature that influences our behaviors and gender-based mannerisms?
Is it nurture? We will never know.

This is when gender
psychology comes in with the latest research in human development and gender theory so
that all those answers can be answered appropriately.
