The document outlines Sigmund Freud's psychoanalytic and psychosocial approach. It discusses Freud's theories on the unconscious mind, personality structures like the id, ego and superego, psychosexual development stages from oral to genital, and defense mechanisms. The personality is divided into conscious, preconscious and unconscious levels. Behavior is driven by libidinal and aggressive instincts. Psychic energy gets fixated during childhood development stages if a child faces trauma.
