In human interactions, the facial expression of a bargaining partner may contain relevant information that affects prosocial decisions. We were interested in whether facial expressions of the recipient in the dictator game influence dictators' behavior. To test this, we conducted an online study ( = 106) based on a modified version of a dictator game. The dictators allocated money between themselves and another person (recipient), who had no possibility to respond to the dictator. Importantly, before the allocation decision, the dictator was presented with the facial expression of the recipient (angry, disgusted, sad, smiling, or neutral). The results showed that dictators sent more money to recipients with sad or smiling facial expressions and less to recipients with angry or disgusted facial expressions compared with a neutral facial expression. Moreover, based on the sequential analysis of the decision and the interaction partner in the preceding trial, we found that decision-making depends upon previous interactions.
在人际互动中，谈判对手的面部表情可能包含影响亲社会决策的相关信息。我们感兴趣的是，独裁者游戏中接受者的面部表情是否会影响独裁者的行为。为了检验这一点，我们进行了一项在线研究（n=106），该研究基于独裁者游戏的一个修改版本。独裁者在自己和另一个人（接受者）之间分配资金，而接受者没有回应独裁者的可能性。重要的是，在分配决策之前，独裁者会看到接受者的面部表情（愤怒、厌恶、悲伤、微笑或中性）。结果表明，与中性面部表情相比，独裁者会向悲伤或微笑的接受者发送更多的钱，而向愤怒或厌恶的接受者发送的钱更少。此外，基于对前一个试验中的决策和交互伙伴的顺序分析，我们发现决策取决于之前的交互。
