Abstract:

Three experiments were conducted to investigate the effects of the opponent’s happy, neutral, and angry facial expressions on individuals’ cooperative behaviors and the mediating and moderating roles of related variables. The results showed that participants were found to be more cooperative towards happy opponents compared to angry ones, and the expectations of opponents’ cooperation mediated the relationship between emotional facial expressions and participants’ cooperative behaviors (Experiment 1); only under the condition of intuitive decision mode, participants were found to be more cooperative towards happy and neutral opponents compared to angry ones, and the expectations of opponents’ cooperation mediated the relationship between emotional facial expressions and participants’ cooperative behaviors (Experiment 2); only under the condition of time constraint, participants were found to be more cooperative towards happy opponents compared to angry and neutral ones, and the expectations of opponents’ cooperation mediated the relationship between emotional facial expressions and participants’ cooperative behaviors (Experiment 3). Based on these results, a moderated mediation model was established to reveal the complex relationships among emotional facial expressions, expectations of cooperation, cooperative behaviors, and individuals’ decision-making modes.

Key words: emotional facial expressions, expectations of cooperation, cooperative behaviors, decision modes, social functions of emotions
