In a computer-mediated negotiation experiment (N = 107), we investigated how a group representative's standing in the group, group norm, and the representative's need to belong influence behavior in intergroup negotiations. We hypothesized that the extent to which peripheral representatives adhere to group norms is contingent on their need to belong, whereas prototypical representatives behave in norm-congruent ways regardless of their need to belong. In support of this idea, results showed that prototypicals behaved more cooperatively when the group norm prescribed cooperation rather than competition. By contrast, peripherals only adhered to the group norm when they had a high need to belong. These findings suggest that peripherals only represent the interests of their group when doing so furthers their self-interest. We discuss implications for theorizing about prototypicality, social exclusion, and conformity to group norms. http://repub.eur.nl/res/pub/8502/ 2006-08-01T00:00:00Z How does a representative's position in the group influence behaviour in intergroup negotiation? Applying insights from the social identity approach (specifically self-categorization theory), the effects of group member prototypicality, accountability, and group attractiveness on competitiveness in intergroup bargaining were examined. As representatives of their group, participants engaged in a computer-mediated negotiation with a simulated outgroup opponent. In Exp. 1 (N = 114), representatives with a peripheral status in the group sent more competitive and fewer cooperative messages to the opponent than did prototypical representatives, but only under accountability. Exp. 2 (N = 110) replicated this finding, and showed that, under accountability, peripherals also made higher demands than did prototypicals, but only when group membership was perceived as attractive. Results are discussed in relation to impression management and strategic behaviour.
