Defining the common feature : task-related differences as the basis for dyadic identity

Abstract

In this paper, we present an experimental study that examines the influence of work-goal differences and informational differences on the formation of a common identity in dyads. We show that when both kinds of differences are present within a dyad, these differences-- just like similarities--come to be seen as defining dyadic features. Furthermore, mediational analysis shows that as the accumulation of differences results in a clearer conception of the dyad, it fosters dyadic identification. This is not the case when dyad members only differ from each other in one respect (i.e. either in work goals or information), while remaining similar in the other. The results are explained in the light of recent insights and developments in the social identity tradition.
