Prisoner's Dilemma Game

Is it better to cooperate or defect?  In this game, students participate in a real life prisoner's dilemma game.  Each student has a partner and a red and black playing card to indicate which of two choices the student prefers.  Each choice corresponds to a different payoff.  There are five rounds and the total payoff in each round is determined by what both students in the partnership choose.  The idea for this game came from a paper written by Charles A. Holt (University of Virginia, Department of Economics) and Monica Capra (Emory University, Department of Economics).  For instructions and the paper, click the "Resources" tab.
