Many personality variables have been used to predict behavior in small group interactions, with mixed success. One such interaction, the prisoner's dilemma, has the S decide whether to adopt the conservative noncooperative strategy or gamble on the cooperative strategy-gamble because the S will receive the most desired payoff if cooperation is achieved, but the least desired payoff if his opponent-partner is unwilling to cooperate. The decision should depend in part on the S's att's toward risk. S's' risk att's were measured by a series of choices in a lottery choice exp. The principal hypothesis was that S's who were relatively risk preferrers would be more cooperative. The data corroborated this hyp, but the diff was not signif at conventional levels. A subsidiary hypothesis stemmed from the fact that a S might have confronted 1 of 3 prisoner's dilemma matrices (2 of the matrices were generated by subtracting a constant amount from each payoff in the 1st matrix). The 3 matrices allowed a test of the hypothesis that utility is linear with money for small positive & negative payoffs (as is commonly hyp'ed in the theory of games). It was conjectured that behavior wquld vary between matrices since it was felt that this hypothesis is a tenuous one. All of the results were in the hyp'ed direction, but some diff's were not signif. Finally, it was hyp'ed & shown that most S's would make a substantial attempt to achieve cooperation. AA.
