When referring to epigenetic theory, it is a relatively new theory that focuses on the genetic origins and how they are affected by the interactions with the environment. Proponents of this theory believe that over time environmental forces will impact the expression of certain genes. On the other hand, the environmental theory removes the genetic factor. This theory believes that a child is a product of direct interaction with their environment.

As children further develop, Freud states they experience the “Oedipus Complex” which involves boys falling in love with their mothers and girls falling in love with their fathers. More focus is placed on the boys at this stage with the girls being considered by Freud as a “dark continent” (Quigley, 1998).

Watson believed that one’s environment was the driving force behind development with no attention paid to the subconscious. He felt that the environment in which one was place was the “determinant factor in behavior” (Hall). “[T]o the behaviorist, normal behavior results from...
