Freud believed that events in childhood shape our adult personality.
Psychological development in childhood takes place through 5 (psychosexual) stages:Oral, Anal, Phallic, Latency, and Genital.
Each stage in Freud's psychoanalytic theory represents the focus of the libido.
Problems at any stage in Freud's psychoanalytic theory can lead to a fixation.
A fixation in Freud's psychoanalytic theory can lead to problems in adulthood.
A fixation can occur at any stage in Freud's psychoanalytic theory through frustration or overindulgence.
Frustration in Freud's psychoanalytic theory occurs when the stage has not been resolved because the needs have not been met.
Overindulgence in Freud's theory is where the needs of the child have been more than satisfied and the child feels reluctant to move to the next stage.
