This document discusses various defense mechanisms in psychology. It provides examples of displacement, where unacceptable feelings towards one person are transferred to a safer target. Rationalization is supplying logical reasons instead of the real reason, like claiming to be fired for not kissing up when the real cause was poor performance. Denial is refusing to accept facts or experiences, like saying one is a social drinker when actually an alcoholic. Sublimation is acting out unacceptable impulses in socially acceptable ways, like becoming a surgeon due to a desire to cut. Reaction formation takes the opposite belief because the true belief causes anxiety, like a boy acting disinterested around a girl he actually likes.
