In humans and animal models, oxytocin increases social closeness, attachment and prosocial behaviors, while decreasing anxiety and stress levels. Efficiently triggering the release of endogenous oxytocin could serve as a powerful therapeutic intervention for disorders of social behavior and for anxiety. We designed a new version of a social sensorimotor synchronization task to investigate the role of social approval in inducing biochemical and psychological changes following behavioral synchrony in a sample of 80 college students. Social approval in the form of real time positive feedback increased well-being only in women, while increasing social closeness in both genders. Social disapproval in the form of real time negative feedback prevented a decrease in stress levels that otherwise women reported following engagement in either social or non-social synchronization. Surprisingly, for certain personality traits, negative social feedback during sensorimotor synchronization was psychologically beneficial irrespective of gender. Salivary oxytocin levels increased only in women after the social but not the non-social synchronization tasks. Oxytocin dynamics were independent of the type of real time feedback that subjects received, indicating the existence of distinct mechanisms for hormonal versus behavioral changes following synchronization. Nevertheless, changes in salivary oxytocin after positive social feedback correlated with changes in well-being and predicted changes in prosocial attitudes. Our findings show evidence of distinct mechanisms for behavioral versus hormonal changes following social sensorimotor synchronization, and indicate that gender and personality traits should be carefully considered when designing behavioral therapies for improving social attitudes and for stress management.
在人类和动物模型中，催产素可增强社会亲近感、依恋感和亲社会行为，同时降低焦虑和压力水平。有效触发内源性催产素的释放可作为一种强大的治疗干预手段，用于治疗社会行为障碍和焦虑症。我们设计了一个新版本的社会感觉运动同步任务，以研究在80名大学生样本中，社会认可在行为同步后诱导生化和心理变化方面的作用。实时积极反馈形式的社会认可仅在女性中提高了幸福感，而在两性中都增强了社会亲近感。实时负面反馈形式的社会不认可阻止了压力水平的下降，否则女性在参与社会或非社会同步后会报告压力水平下降。令人惊讶的是，对于某些人格特质，感觉运动同步期间的负面社会反馈在心理上是有益的，与性别无关。仅在社会同步任务后，女性的唾液催产素水平才会升高，而非社会同步任务后则不会。催产素动态与受试者收到的实时反馈类型无关，表明同步后激素变化与行为变化存在不同机制。尽管如此，积极社会反馈后唾液催产素的变化与幸福感的变化相关，并预测亲社会态度的变化。我们的研究结果表明，社会感觉运动同步后行为变化与激素变化存在不同机制，并表明在设计改善社会态度和压力管理的行为疗法时，应仔细考虑性别和人格特质。
