According to Freud, projection occurs when a person attributes his or her own unacceptable desires to others. This woman is wondering what it would be like to be with another man, but that is unacceptable for her to admit to her husband, so instead she tells her husband that other men are coming on to her. Introjection involves incorporating the standards and values of others so that they are not dissonant with their own beliefs. Displacement occurs when a person takes out their aggression on an involvement "safe" target. For example, a woman who is angry towards her husband may yell at the dog instead of yelling at her husband. Repression occurs when a person ignores or removes from consciousness a painful event or memory. One example would be in repressed memories of sexual abuse. It is assumed that some people will erase from their memory events of sexual abuse in order to protect themselves. With compensation, a person will build up other aspects of himself or herself to adjust for any perceived weaknesses. For example, a person who believes that they are not good at sports may throw him or herself into studying to develop their intellect.
