Suppression is the conscious attempt to hide or prevent unacceptable thoughts, feelings and motives. Repression, on the other hand, is a more complicated mechanism operating at the unconscious level  Projection is defined simply as projecting one’s unacceptable drives, feelings, motives, faults and flows to other people. Rationalization generally occurs when the ego experiences a feeling of guilt, due to an unacceptable drive, feeling or because of a faulty behavior and it is diiicult for the person to accept the responsibility at the conscious level. Denial is defined as ignoring the threatening, anxiety provoking thoughts, feelings, motives, or sometimes even events and realities.
