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...

An examination of the behavioral effect of repeated terrorist attacks reveals that local residents (of the attacked area) appear to be much less sensitive to this risk than international tourists. Furthermore, the limited sensitivity on the part of local residents seems to diminish with time,...

Groups of five players participated in a social dilemma game in which each player receives a monetary endowment and then chooses whether to contribute it to a monetary public good. The good is provided to all group members if at least three contributions are made; it is not provided, otherwise....

This paper presents the results of an n-person characteristic function game played by between seven and and twelve players, one of whom was a monopolist. A factorial design allowed for analysis of the effects of group size, the availability of information, and communication opportunities for a...

Several models of prisoner's dilemma interactions were tested in a series of twelve games whose termination point was determined probabilistically. A new model was introduced to discriminate among equilibrium and nonequilibrium situations on the basis of a player's expected benefits or losses...
