SIGMUND FREUD'S PSYCHOSEXUAL THEORY OF DEVELOPMENT
Freud theorized that the core of personality is formed before age 6 in a series of psychosexual stages. Each stage focuses on a different sexually excitable zone of the body, or erogenous zones. The way the child learns to fulfill the sexual desires associated with each stage becomes an important component of the child's personality. Failure to pass through these stages in the normal manner is the cause of various psychosexual disturbances and character disorders. Freud believed that erotic childhood urges have lasting effects on development.
He theorized that many adult personality traits can be traced to fixations, the unresolved conflict or emotional hang up caused by overindulgence or by frustration. In fixation, the individual behaves according to the characteristics of a particular psychosexual stage of childhood.
