Freud's psychoanalytic theories refer to the psychological theories developed by Sigmund Freud that focus on the unconscious mind, childhood experiences, and the role of early development in shaping personality.
The id is an aspect of Freud's psychoanalytic theory that represents our primitive desires and operates on the pleasure principle. It seeks immediate gratification without considering consequences.
The ego is another aspect of Freud's theory which serves as the mediator between the id, superego, and reality. It balances our desires with societal norms and tries to find compromise.
