A focus theory of normative conduct: When norms do and do not affect behavior

In three experiments, respondents' behavior conformed to the dictates of a relevant norm (the norm against littering) only under conditions of normati ve focus. This relationship held true across three types of procedures for producing normative focus (physiological arousal, modeling, and self-direct ed attention), across two types of settings (public and private), and acros s two types of norms (social and personal). Moreover factors that would be expected to affect normative action were influential only when the norm was focal. These factors included the degree to which the action violated the relevant norm (Study 2) and the degree to which an individual subscribed to that norm (Study 3). Implications are discussed for developing campaigns t o encourage prosocial behavior.
