We surveyed organizational employees (N ¼ 215); assessing the effect of self-uncertainty and how autocratic they perceived their organizational leader to be on measures of leader support. As predicted, less self-uncertain participants were more supportive of a non-autocratic than autocratic leader, whereas the opposite was the case for more self-uncertain participants—they were more supportive of an autocratic than non-autocratic leader. The effect was mediated by perceived group prototypicality of the leader. Implications for uncertainty-identity theory and for a wider analysis of the role of uncertainty in leadership are discussed. http://repub.eur.nl/res/pub/32834/ 2012-04-01T00:00:00Z Intergroup leadership-leadership of collaborative performance of different organizational groups or organizations-is associated with unique intergroup challenges that are not addressed by traditional leadership theories. To address this lacuna, we describe a theory of intergroup leadership. Firmly grounded in research on social identity and intergroup relations, the theory proposes that effective intergroup performance rests on the leader's ability to construct an intergroup relational identity. We describe key leadership actions to establish such an identity. http://repub.eur.nl/res/pub/21519/ 2010-11-01T00:00:00Z This study explores the role of intragroup dynamics in intergroup conflict. 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. http://repub.eur.nl/res/pub/11864/ 2005-08-01T00:00:00Z Researchers in leadership effectiveness are paying increasing attention to the role of follower self-concept and identity as a mediator and moderator of the effectiveness of leadership. In this introductory article, we provide a short outline of this rapidly growing field of research, briefly introduce the articles presented in this special issue on leadership, self, and identity, and highlight key themes for future research that we feel emerge from these studies. These themes include greater attention to the dynamic interplay between leaders and followers, the incorporation of theories of fairness, and the role of leader self-concept. http://repub.eur.nl/res/pub/12106/ 2004-12-01T00:00:00Z This article reviews empirical research on the role of follower self-conception in leadership effectiveness, and specifies an agenda for future research in this area. The review shows that several aspects of follower selfconception (i.e., self-construal, self-efficacy, self-esteem, and self-consistency) may be affected by leadership, and may mediate the effects of leadership on follower behavior. There also is consistent evidence that follower selfconstrual moderates the impact of leadership on follower attitudes and behavior. Two key themes for future research are defined. First, future research should focus on the development of theory about the role of relational self-construal in the leadership process. Second, it seems particularly valuable to develop theory about the interplay of different aspects of follower self-conception in leadership effectiveness, including the interactive effects of these aspects of self. Working backwards from these theoretical models of follower self-conception, specific leader behavior relevant to these aspects of self should then be identified. http://repub.eur.nl/res/pub/12117/ 2003-12-01T00:00:00Z Research into leadership effectiveness has largely overlooked the implications of the fact that leadership processes are enacted in the context of a shared group membership, where leaders, as group members, ask followers, as group members, to exert themselves on behalf of the collective. In contrast, the social identity model of organizational leadership, proposed here, emphasizes the characteristics of the leader as a group member, and the leader’s ability to speak to followers as group members. In salient groups with which group members identify, leadership effectiveness rests on the extent to which the leader is prototypical of the group (i.e. representative of the group’s identity) and engages in group-oriented behavior (i.e. behavior perceived to benefit the group). Explicating the added value of our model and going beyond contemporary approaches to leadership effectiveness, we discuss how our model extends, and may be integrated with, three major contemporary approaches to leadership effectiveness (charismatic leadership theories, Leader-Member Exchange theory, and leadership categorization theories). In addition, we outline how our model provides a viable framework to integrate future developments in research on leadership such as a growing attention to leader fairness and the role of emotions in leadership effectiveness. http://repub.eur.nl/res/pub/12200/ 2001-07-01T00:00:00Z
