Running Head: ATTITUDE-BEHAVIOUR RELATIONS Social identity and the attitude-behaviour relationship: Effects of anonymity and accountability

Two experiments were conducted to examine the impact on anonymity and accountability on the expression of group-mediated attitude-behaviour consistency. In Study 1, low and high identifiers (N = 106) were exposed to an attitude-congruent norm and provided information on intentions under anonymous and in-group accountable conditions. In Study 2, salience of identity was manipulated, participants (N = 185) were exposed to either an attitude-congruent or an attitude-incongruent norm, and provided information on intentions and behaviour under anonymous and in-group accountable conditions. In both studies, accountability elicited group-normative attitudes and behaviour among individuals for whom the group was not a salient basis for self-definition. For individuals for whom the group was a salient basis for self-definition, the expression of attitude-consistent intentions and behaviour was greater in anonymous conditions. It is suggested that strategic concerns, such as those elicited by in-group accountability, influence displays of groupnormative attitude-behaviour consistency. 2
