What are Freud's three structures of personality?

Freud proposed that personality consists of three interacting systems. The id operates on the pleasure principle, demanding immediate gratification of basic drives and impulses without regard for reality or morality. It is entirely unconscious and present from birth. The ego operates on the reality principle, mediating between the id's desires and the constraints of the real world by finding realistic ways to satisfy needs. It develops in early childhood. The superego represents internalized moral standards and ideals, producing guilt when violated and pride when upheld.
