“…By using systematic variations of the intergroup context in which the social dilemma was embedded, this research provided insight into how contributions to public goods, which influence both in-group and out-group members, shape social perceptions. Second, we extend recent research on social motives in intergroup conflict (De Dreu, 2010;De Dreu et al, 2010;Halevy et al, 2008Halevy et al, , 2010Halevy, Weisel, & Bomstein, 2011) by showing that the structure of an intergroup conflict (e.g., IPD vs. IPD-MD vs. nested social dilemma) has important consequences not only on intergroup behavior and the conflict's outcomes but also on social perceptions, attributions, and actions, and through them, on intragroup processes such as the emergence of social hierarchy. Finally, we contribute to the literature on social hierarchy by illustrating the usefulness and importance of decomposing status into prestige and dominance (Cheng et al, 2010;Henrich & Gil-White, 2001).…”
