This study examined if the prosocial effects of oxytocin (OT) extend from individuals to a generalized other who is in need. Participants played a series of economic games to earn money and were presented with an opportunity to donate a portion of their earnings to charity. OT did not significantly increase the decision to donate, but among the 36% of participants who did donate, people infused with OT were found to donate 48% more to charity than those given a placebo. The amount of money earned in the experiment had no effect on whether or not a donation was made or the size of a donation. This is the first study showing that OT increases generosity in unilateral exchanges directed toward philanthropic social institutions, as opposed to immediate benefits directed at individuals or groups.
这项研究考察了催产素（OT）的亲社会效应是否会从个体扩展到需要帮助的广义他人。参与者玩了一系列经济游戏来赚钱，并获得了向慈善机构捐赠部分收入的机会。OT 并没有显著增加捐赠的决定，但在 36%的捐赠参与者中，接受 OT 注射的人比接受安慰剂的人向慈善机构捐赠的金额多 48%。实验中赚取的钱的数量对是否进行捐赠或捐赠的金额没有影响。这是第一项表明 OT 增加了对慈善社会机构的单向交换的慷慨程度，而不是对个人或团体的直接利益的研究。
