Abstract

The purpose of this study is to investigate the dynamic effects of the affiliation motive, a personal characteristic factor, and the level of power-holding, an environmental factor, upon the cooperative behavior. In the subject screening stage, 568 female university students were tested on the Affiliation Motive Scale (Cha, 1984). And on the base of the result of the subject screening stage, intimacy group and fear of rejection group were divided. In the experimental stage, the Prisoner's Dilemma Game(PDG) was used to manipulate the power level and to measure the degree of cooperative moves. The results of an ANOVA were as follows ; The total mean of cooperative moves score was high. The intimacy motive group cooperated more than the fear of rejection group and the high power group also cooperated more than the low power group. Also, since the intimacy motive group did not influence the power-holding level, they showed high cooperative moves consistently. The fear of rejection group was similar to the intimacy motive group when they were in the high power condition, but in the low power condition, they showed the least cooperative moves.
