- Sigmund Freud believed human behavior is motivated by the id, ego, and superego. The id seeks pleasure and avoids pain instinctively. The ego uses reason and logic to satisfy the id's desires in socially appropriate ways. The superego incorporates moral values learned from parents and society.
- According to Freud, the unconscious mind influences behavior in ways people are unaware of. Repressed desires, urges, and traumatic experiences from childhood are buried in the unconscious mind.
- Psychoanalysis aims to make the unconscious conscious through talking. Bringing hidden desires and experiences to awareness can help address emotional and behavioral problems.
