这是首次报道人类内源性催产素与社会行为有关，这与大量动物文献一致。受试者陷入一种社会困境，其中缺乏沟通、合作行为可以使随机分配到二人组的双方受益。之所以出现这种困境，是因为在得知另一方的行为反应之前，一个参与者必须做出金钱牺牲，以表明对另一方的信任程度。我们发现，与接受相同平均金额的随机货币转移的受试者相比，收到信任信号与更高水平的外周催产素相关。催产素水平也与值得信赖的行为有关（分享更大比例的金钱收益）。我们的结论是，催产素可能是促进合作的人类生理学的一部分。
This is the first report that endogenous oxytocin in humans is related to social behaviors, which is consistent with a large animal literature. Subjects are put into a social dilemma in which absent communication, cooperative behavior can benefit both parties randomly assigned to a dyad. The dilemma arises because one participant must make a monetary sacrifice to signal the degree of trust in the other before the other's behavioral response is known. We show that receipt of a signal of trust is associated with a higher level of peripheral oxytocin than that in subjects receiving a random monetary transfer of the same average amount. Oxytocin levels were also related to trustworthy behavior (sharing a greater proportion of the monetary gains). We conclude that oxytocin may be part of the human physiology that motivates cooperation.
