两人和三人最后通牒博弈任务中嗓音吸引力对决策的影响

The present research adopted a two-person ultimatum game and a three-person ultimatum game to examine the effect of vocal attractiveness of a male proposer and the effect of vocal attractiveness of a powerless male third player on decision-making. The results of Experiment 1 showed that the unfair offers from the proposers with attractive voices were more likely to be accepted compared with those from the proposers with unattractive voices. In Experiment 2, in the unfair/fair offer condition in which participants received a smaller allocation than the third player, the acceptance ratio was higher when the third player had an attractive-voice. In conclusion, vocal attractiveness can induce the "beauty premium" which was similar to the effect reported by previous research about facial attractiveness. "
