传染性哈欠被认为是状态匹配中涉及的一种基本形式的同理心。尽管最近有证据支持这种联系，但传染性哈欠的神经化学基础在很大程度上仍然未知。在这里，我们在实验室环境中研究了鼻内催产素（一种参与共情处理、结合和社会关系的激素和神经肽）是否会影响人类参与者的传染性哈欠。采用双盲程序，60名男大学生接受了30剂量的鼻内催产素或安慰剂，然后记录下他们在接触传染性打哈欠视频刺激的过程。与移情模型假说相反，催产素并没有增加传染性哈欠，而是以一种与这种行为相关的社会耻辱意识增强的方式调节其表达。特别是，在催产素条件下的个体更有可能隐藏他们的打哈欠，而不太可能表现出与行为相关的明显线索。后续研究可以探索社会背景和与目标刺激的联系如何改变这种反应。2015爱思唯尔爱尔兰有限公司版权所有。
Contagious yawning is thought to represent a basic form of empathy involved in state matching. Despite recent evidence in support of this connection, the neurochemical basis of contagious yawning remains largely unknown. Here, we investigate whether intranasal oxytocin, a hormone and neuropeptide involved in empathic processing, bonding and social affiliation, influences contagious yawning among human participants in a laboratory setting. Using a double blind procedure, 60 male college students received 30 ID of intranasal oxytocin or placebo and were then recorded during exposure to a contagious yawning video stimulus. Contrary to the empathic modeling hypothesis, oxytocin did not increase contagious yawning but rather appeared to modulate its expression in ways indicative of an enhanced awareness of the social stigma associated with this behavior. In particular, individuals in the oxytocin condition were more likely to conceal their yawns and less likely to display overt cues associated with the behavior. Follow-up research could explore how social context and affiliation with the target stimulus alter this response. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
