Psychoanalytic theory suggests that Defense mechanisms are unconscious processes originating in the ego. Moreover, Defence Mechanism is defined as largely unconscious reactions that protect a person from unpleasant emotions such as anxiety and guilt ; devices the ego uses to keep threatening material out of awareness and thereby reduce or avoid anxiety; strategies the ego uses to defend itself against the anxiety provoked by conflicts of everyday life; tactics that keep unacceptable thoughts, instincts , and feelings out of conscious awareness and thus protect the ego against anxiety Defense mechanisms involve denials or distortions of reality.
