Concept:Repression is an unconscious defense mechanism that pushes painful or threatening memories out of conscious awareness.
Explanation:The question asks for the unconscious process of forgetting.
Repression works automatically and unconsciously to block unpleasant thoughts, memories, or impulses from entering the conscious mind.
It is different from suppression, which is a conscious and deliberate effort to forget.
For example, a person may unconsciously forget a traumatic event because remembering it would cause anxiety or distress.
However, repressed memories can still influence behavior even though the person is not aware of them.
Regression, submission, and projection are other defense mechanisms, but they do not specifically describe unconscious forgetting.
Therefore, repression is the correct answer.
