<unk>  is a theorized psychological behavior in which people may forget unwanted memories, either consciously or unconsciously. It is an example of defence mechanism, since these are unconscious or conscious coping techniques used to reduce anxiety arising from unacceptable or potentially harmful impulses thus it can be a defence mechanism in some ways. Defence mechanisms are not to be confused with conscious coping strategies. Thought suppression is a method in which people protect themselves by blocking the recall of these anxiety-arousing memories. For example, if something reminds a person of an unpleasant event, their mind may steer towards unrelated topics. This could induce<unk>  without being generated by an intention to forget, making it a<unk>  action. There are two main classes of<unk> : psychological repression is an unconscious act, while thought suppression is a conscious form of excluding thoughts and memories from awareness.
