* Norm Violation: Norms are the social rules that guide us and tell us what is right or wrong behaviour. Norms are culturally influenced - what one culture believes to be normal behaviour may be strange and unusual. Therefore, one who lives in a certain culture and violates that cultures norms, may be seen as acting abnormally. However, one must be careful when using this criteria due to the fact that norms from one culture to the next vary so much.
