Which of the following is NOT a defense mechanism identified by Freud?

Freud identified several defense mechanisms that are psychological strategies used to cope with reality and maintain self-image. Repression, regression, and projection are all recognized as classic defense mechanisms.

Repression refers to the process of unconsciously blocking out thoughts, memories, or feelings that are too difficult or painful to deal with. This mechanism helps individuals avoid anxiety by keeping distressing thoughts away from conscious awareness.

Regression is characterized by reverting to behaviors typical of an earlier stage of development when faced with stress or conflict. This might manifest as throwing a tantrum or reverting to childlike behaviors when overwhelmed.

Projection involves attributing one’s own unacceptable thoughts or feelings onto another person. For example, someone who is angry may accuse others of being hostile, thus projecting their own feelings onto someone else.

In contrast, exhibition does not fit within Freud's framework of defense mechanisms. It is not recognized by Freud as a psychological strategy for coping with anxiety or conflict. Therefore, choosing exhibition indicates a misunderstanding of Freud's contributions, as it does not pertain to his established concepts in psychology.
