Psychosexual development

In Freudian Ego psychology, psychosexual development is a central element of the psychoanalytic sexual drive theory. Freud believed that personality developed through a series of childhood stages in which pleasure seeking energies from the child became focused on certain erogenous areas. An erogenous zone is characterized as an area of the body that is particularly sensitive to stimulation. The five psychosexual stages are the oral, the anal, the phallic, the latent, and the genital. The erogenous zone associated with each stage serves as a source of pleasure. Being unsatisfied at any particular stage can result in fixation. On the other hand, being satisfied can result in a healthy personality. Sigmund Freud proposed that if the child experienced frustration at any of the psychosexual developmental stages, they would experience anxiety that would persist into adulthood as a neurosis, a functional mental disorder.
