Freudian Psychology: This refers to Sigmund Freud's psychoanalytic theory which emphasizes unconscious thought processes and early childhood experiences in shaping behavior.
Defense Mechanisms: These are psychological strategies used by individuals unconsciously to cope with anxiety or stress. They often distort reality to protect one's self-esteem.
Id, Ego, Superego: These are three components of Freud's structural model of personality. Id is driven by basic urges, superego represents moral conscience, and ego mediates between them according to reality.
