2005年，Kosfeld等人的一项有影响力的研究表明，催产素增加了对陌生人的信任。在一篇有影响力的论文中，Kosfeld等人（2005）表明，鼻内注射催产素（OT）增加了投资者在信任游戏中的转移，这表明OT增加了对陌生人的信任。随后的研究调查OT在信任游戏中的作用，发现不确定的影响，投资者的信任行为，但这些研究偏离了Kosfeld等人的研究在一个重要的方式，他们没有实现最低限度的社会接触（MSC）之间的信任游戏的投资者和受托人。在这里，我们进行了一项大型的双盲和安慰剂对照的复制研究，研究OT对信任行为的影响，其效力超过95%，并实现了MSC条件以及无社会接触（NoC）条件。我们发现在MSC条件下，OT对信任行为没有影响。探索性事后分析表明，OT可能会增加信任的个人与低倾向的信任在NoC条件，但这一发现需要在未来的研究中确认。
An influential 2005 study by Kosfeld et al. suggested that oxytocin increases trust in strangers. This registered replication study by some of the original authors found no effect of oxytocin on trusting behaviour under the same conditions.In an influential paper, Kosfeld et al. (2005) showed that intranasal administration of oxytocin (OT) increases the transfers made by investors in the trust game-suggesting that OT increases trust in strangers. Subsequent studies investigating the role of OT in the trust game found inconclusive effects on the trusting behaviour of investors but these studies deviated from the Kosfeld et al. study in an important way-they did not implement minimal social contact (MSC) between the investors and the trustees in the trust game. Here, we performed a large double-blind and placebo-controlled replication study of the effects of OT on trusting behaviour that yields a power of more than 95% and implements an MSC condition as well as a no-social-contact (NoC) condition. We find no effect of OT on trusting behaviour in the MSC condition. Exploratory post hoc analyses suggest that OT may increase trust in individuals with a low disposition to trust in the NoC condition, but this finding requires confirmation in future research.
