Abstract: This study used social dilemmas and computer simulation to examine the effects of values orientation on group cooperative behavior. Sixty-two students took part in the experiment. The results showed: (1)Value orientation influenced group cooperative behavior significantly. Cooperative- oriented members tended to cooperate with the partners. (2) Group cooperation behaviors were affected by the partner's strategies in games. The corresponding strategy effectively elicited cooperation on the whole. (3) The interaction between values and strategies had marginal effects on group cooperative behavior.

Key words: social dilemma, value orientation, cooperative behavior
