What are the various factors that may exist in defining abnormality? Abnormality in psychology can be simply used to mean abnormal behavior. Abnormal psychology is the study of abnormal behavior which is the deviation from the norm and how individuals behave in certain situations. There are four main factors applied in the definition of abnormal behavior; personal stress, statistical rarity, the violation of social norms, and maladaptive behavior. Violation of social norms involves changes in personal behavior and a reflection of unexpected actions as deemed so by the society. Maladaptive behavior is developed by individuals in order for them to avoid coping with new adjustments within the immediate environment. The inability to cope with social stress and develop effective coping mechanisms enables a ruling of abnormality as people are geared towards living and coping with the daily stress. Statistical rarity may be associated with biological processes with examination of what is actually the abnormal may it be the function or physiology.
