先前的研究表明，积极情绪的自发表现可能是人类合作倾向的可靠信号。与这一命题相一致的是，一些研究发现，自我报告的合作者确实比不合作者表现出更高水平的积极情绪。在这项研究中，我们定义了合作者和不合作者在他们的行为作为提议者在最后通牒游戏，并录像他们的面部表情，因为他们面对不公平的报价作为回应。对参与者面部表情的详细分析显示，在最后通牒游戏中，合作者在回应不公平的提议时表现出更多的情感表达，而不仅仅是积极的情感表达。这些结果表明，合作者可能比非合作者更容易表达情感。我们推测，情绪表达能力可能是一个更可靠的信号合作比显示积极的情绪。
Previous research has suggested that the spontaneous display of positive emotion may be a reliable signal of cooperative tendency in humans. Consistent with this proposition, several studies have found that self-reported cooperators indeed display higher levels of positive emotions than non-cooperators. In this study, we defined cooperators and non-cooperators in terms of their behavior as the proposer in an ultimatum game, and video-taped their facial expressions as they faced unfair offers as a responder. A detailed analysis of the facial expressions displayed by participants revealed that cooperators displayed greater amounts of emotional expressions, not limited to positive emotional expression, when responding to unfair offers in the ultimatum game. These results suggest that cooperators may be more emotionally expressive than non-cooperators. We speculate that emotional expressivity can be a more reliable signal of cooperativeness than the display of positive emotion alone.
