Question

Quizplus · Accepted Answer

All defense mechanisms have in common the function of keeping threatening impulses, thoughts, or feelings from becoming conscious. They work to protect our self-image and reduce anxiety by distorting reality or blocking awareness of emotions or stimuli that may cause discomfort. While some defense mechanisms may become maladaptive or cause harm, not all of them are necessarily harmful. Also, some defense mechanisms may operate at an unconscious or subconscious level, making them hard to observe or acknowledge without introspection or therapy.
