The neuropeptide oxytocin has a popular reputation of being the 'love' hormone. Here we test meta-analytically whether experiments with intranasal administration of oxytocin provide support for the proposed effects of oxytocin. Three psychological effects were subjected to meta-analysis: facial emotion recognition (13 effect sizes, N=408), in-group trust (8 effect sizes, N=317), and out-group trust (10 effect sizes; N=505). We found that intranasal oxytocin administration enhances the recognition of facial expressions of emotions, and that it elevates the level of in-group trust. The hypothesis that out-group trust is significantly decreased in the oxytocin condition was not supported. It is concluded that a sniff of oxytocin can change emotion perception and behavior in trusting relationships.
神经肽催产素素有“爱情激素”的美誉。在这里，我们通过荟萃分析来检验鼻内给予催产素是否支持催产素的预期作用。我们对三种心理效应进行了荟萃分析：面部情绪识别（13 个效应量，N=408）、内群体信任（8 个效应量，N=317）和外群体信任（10 个效应量；N=505）。我们发现，鼻内给予催产素可增强对情绪面部表情的识别能力，并提高内群体信任水平。鼻内给予催产素会显著降低外群体信任的假设未得到支持。结论是，嗅一嗅催产素可以改变信任关系中的情绪感知和行为。
