Two team games are introduced: a game of assurance and a game of chicken. The games were operationalized as a competition between two teams, with three players on each team, and were compared either with or without the opportunity for a within-team discussion. The authors found that the vast...

The authors introduce a new team game, the intergroup chicken game, to model intergroup conflicts involving bilateral threats (e.g., military conflicts, industrial disputes). The group that wins the game is the one that competes while the other group yields, and the benefits associated with...

Forty-eight groups participated once in an intergroup conflict in which two groups of equal or unequal size competed for the provision of step-level (binary) public goods. The study included a two-factorial design with preplay communication versus no preplay communication defining one dimension,...

The intergroup prisoner's dilemma (IPD) game was played repeatedly in an attempt to distinguish the dynamic process associated with reciprocation at the intergroup level from that resulting from adaptation at the individual level. Results show that when players were not allowed to communicate...

Repeated interaction in integroup conflict was studied in the context of two team games: the intergroup public goods (IPG) game and the intergroup prisoner's dilemma (IPD) game. The results reveal (a) a main effect for game type; subjects were twice as likely to contribute toward their group...

Two types of intergroup conflicts modeled as team games, a game of assurance where the groups' incentive to compete is purely fear and a game of chicken where the groups' incentive to compete is purely greed, are examined. The games involved competition between two 3-person groups. The players...
