Cooperation in pairs of rats playing the prisoner's dilemma game was investigated. Six pairs of animals were taught to make either cooperative or uncooperative responses by running to one or the other end of a T-maze. Two T-mazes were joined together such that animals could respond simultaneously. Animals were run under conditions in which visual communication was present and absent. Mutually uncooperative responses were the most common and mutually cooperative behaviors the least preferred. Introduction of a barrier between the mazes, which removed visual communication between pairs, sharply accentuated uncooperative behavior. Similarities of the present findings to results with human subjects and the implications of using game theory for studying cooperative behavior in animals are discussed.

39 high school girls from the North Carolina School of the Arts (NCSA group) and 39 comparable girls from a regular city-county school system (HS group) were compared on degree of cooperative behavior to assess group differences between artistically oriented students and regular HS students. Cooperative behavior was assessed by having each S make 50 cooperative or competitive choices in the Prisoner's Dilemma game. The NCSA group was expected to be more competitive because within the performing arts, competition is a pervasive characteristic. Each Ss opponent was an accomplice of E who responded according to a predetermined schedule containing 76% cooperative responses. Each S changed opponents (accomplices) and repeated 50 trials under the same conditions. The NCSA group was less cooperative than the HS group ( p < .01) except on the initial trials, and there was less cooperation on the second game than on the first ( p < .01). The HS group did not decrease across trials in Game 1 as had been expected. The decrease in cooperation at the beginning of Game 2 was more marked for the NCSA group. Five scales on the Adjective Check List differentiated the groups.

The present study examined the effects of opponent's cooperation and honesty on the cooperation of 80 like-sexed pairs who played 40 trials of a Prisoner's Dilemma Game. Ss faced an opponent programmed by E to be either Honest-Cooperative, Honest-Competitive, Dishonest-Cooperative, or Dishonest-Competitive. Post-game ratings indicated that a majority of Ss perceived the opponent as competitive and honest regardless of the opponent's actual behavior. Ss' perception was significantly associated with their cooperative behavior, with accurate perceivers being less cooperative than inaccurate perceivers. The greater competitiveness of accurate perceivers was tentatively explained as a function of their more extensive use of the cues generated directly by the experimental context.
