How do our emotional tears affect the way we are treated? We tested whether tears, paired with either a neutral or a sad facial expression, elicited prosocial behavior among perceivers. Participants viewed a video clip depicting a confederate partner with or without tears displaying either a neutral or sad facial expression before making a behavioral decision in one of two economic games. In a Trust game (Experiment 1), participants who played the role of the investor were more likely to share an endowment after viewing a confederate trustee with tears (paired with either a neutral or a sad facial expression) in comparison to a confederate trustee without tears. However, in a Dictator game (Experiment 2), participants who played the role of allocator were no more likely to share an endowment after viewing a confederate recipient with tears (paired with either a neutral or sad facial expression) in comparison to a confederate recipient without tears. Taken together, these findings suggest that tears increase prosocial behavior by increasing trustworthiness as opposed to generally increasing other-regarding altruistic tendencies.

情感上的眼泪：可信度增加亲社会行为的诚实信号？

我们情感上的眼泪如何影响我们被对待的方式？我们测试了眼泪与中性或悲伤的面部表情搭配是否会引发感知者的亲社会行为。参与者在两个经济游戏之一做出行为决定之前，观看了一段视频剪辑，该视频剪辑描绘了一个有或没有眼泪的同盟伙伴，表现出中性或悲伤的面部表情。在信任游戏（实验 1）中，扮演投资者角色的参与者在看到联盟受托人流泪（搭配中性或悲伤的面部表情）后，与没有看到联盟受托人的人相比，更有可能分享捐赠。眼泪。然而，在独裁者游戏（实验 2）中，与同盟接收者相比，扮演分配者角色的参与者在看到同盟接收者流泪（搭配中性或悲伤的面部表情）后分享捐赠的可能性并没有更高没有眼泪。总而言之，这些发现表明，眼泪通过增加可信度来增加亲社会行为，而不是普遍增加有关他人的利他倾向。
