Abnormity

In psychology, abnormality is a behavioral characteristic assigned to those with conditions that are regarded as dysfunctional. Behavior is considered to be abnormal when it is atypical or out of the ordinary, consists of undesirable behavior, and results in impairment in the individual's functioning. As applied to humans, abnormality may also encompass deviance, which refers to behavior that is considered to transgress social norms. The definition of abnormal behavior in humans is an often debated issue in abnormal psychology.
