Which of the following is NOT one of Freud's ego defense mechanisms?

Repression, one of Freud's well-known ego defense mechanisms, involves unconsciously blocking out distressing thoughts, feelings, or memories. It serves to protect the individual from anxiety or emotional pain by relegating these experiences to the unconscious mind.

In contrast, compensation is a mechanism where an individual attempts to cover up perceived weaknesses by emphasizing strengths. Displacement occurs when a person redirects their feelings from a threatening target to a less threatening one. Identification involves adopting the characteristics of another person to enhance self-esteem or reduce anxiety.

Since repression is indeed one of Freud's identified defense mechanisms, identifying it as the correct answer would be mistaken. Understanding the nuanced roles that these mechanisms play in Freud's theory can help clarify their purpose in coping with stress and maintaining psychological equilibrium.
