Freud's Psychosexual Theory posits that human development occurs in five stages—oral, anal, phallic, latency, and genital—each associated with a specific erogenous zone. As individuals progress through these stages, unresolved conflicts can lead to fixations, influencing adult personality and behavior. This theory emphasizes the role of unconscious desires and childhood experiences in shaping personality.| Simply Psychology
The Oedipal complex occurs during the Phallic stage of development (ages 3-6) in which the source of libido (life force) is concentrated in the erogenous zones of the child's body (Freud, 1905).| Simply Psychology
