Identity in work groups : the beneficial and detrimental consequences of multiple identities and group norms for collaboration and group performance / Naomi Ellemers, Floor Rink -- The effects of status and group membership modeled in a graph-theoretic setting / Christopher Barnum -- Politicized...

This paper examines social influence in collective task settings using the Berger, Fisek, Norman and Zelditch's graph-theoretic method. The work examines in-group membership in task settings, and models contexts where both status processes and group membership are salient. At the core of these...

This chapter reviews recent theoretical developments and empirical research, to examine the causes and consequences of identity processes in relation to collaboration in work groups and group performance. Our central proposition is that identification in work groups can have beneficial as well...

Two decades of research have identified a robust effect: Members of decision-making groups mention and repeat shared information that all members know more so than unshared information that a single member knows. This chapter explores the idea that processes related to member status both affect...

We examine the influence of team size on decision making in a beauty-contest experiment. Teams with four members outperform teams with two members and single persons significantly, whereas the latter two types of decision makers do not differ.
