Studies have shown that the evolutionarily conserved neuropeptide oxytocin (OT) promotes various prosocial behaviors, yet there are few studies of the effect of OT on social judgments, especially on judgments when the actor's intention and the final outcome are incongruent. In a double-blind, placebo-controlled experiment, participants were asked to play the role of the recipient in a dictator game and to make social judgments about the dictator after intranasal OT administration. To isolate the outcome and the intention of the dictator's allocation, we developed a novel social judgment task in which recipients were told that 50% of the dictators' proposals would be reversed. The results showed that the effect of OT on social judgment was modulated by intention: OT increased goodness ratings only towards dictators with hyperfair intention. Our findings support the affiliative-motivation theory which states that OT enhances the affiliative motivation and recognition of positive-valence social stimuli.
研究表明，进化上保守的神经肽催产素（OT）促进了各种亲社会行为，但关于 OT 对社会判断的影响，特别是关于行为者的意图和最终结果不一致时的社会判断的研究较少。在一项双盲、安慰剂对照实验中，参与者被要求在独裁者游戏中扮演接受者的角色，并在鼻内给予 OT 后对独裁者进行社会判断。为了分离独裁者分配的结果和意图，我们开发了一种新的社会判断任务，其中接受者被告知 50%的独裁者的提议将被反转。结果表明，OT 对社会判断的影响受到意图的调节：OT 仅增加了对具有超公平意图的独裁者的好评。我们的发现支持了亲和动机理论，该理论指出 OT 增强了亲和动机和对积极价值社会刺激的识别。
