Question

In what way did Sigmund Freud advance our understanding of psychology?

Answer 1

Freud was one of the first to infer that mental disorders could be a result of individual history, and not just physical impairment.

Freud developed a complete theory of personality, composed of an interplay between psychic structures and incidents within psychosexual stages of development.

Although Freud�s specific theories have been roundly criticized for their circularity and gender specificity since their introduction, it should be remembered:

Freud sparked the psychological revolution and personally trained the second generation of psychoanalysts.

Freud introduced a new way of analyzing human behavior which was adapted by many psychiatrists and psychologists in Neo & Non-Freudian terms.
