观看一个活生生的面部表情通常会让观察者产生一个类似的表情（面部模仿），这与一种和谐的情绪体验（情绪感染）有关。具身情绪模型提出，情绪感染和面部模仿在功能上是联系在一起的，尽管神经基础尚不清楚。为了解决这一知识差距，我们采用了一个活的两个人的范例（n = 20二人组），使用功能性近红外光谱在现场情绪面部处理，同时还测量眼动跟踪，面部分类和情绪评级。其中一个二元合作伙伴，“电影观察者”，被要求在观看令人回味的短片时表现出自然的面部表情。另一个搭档‘看脸人’，则是看电影人的脸。任务块和休息块是由透明和不透明的玻璃分隔开的。在实验过程中，二元角色交替。面部表情的平均跨伴侣相关性（r = 0.36 ± 0.11 s.e.m.）和平均跨伴侣情感评分（r = 0.67 ± 0.04）分别与面部模仿和情绪感染相一致。神经相关的情感感染的基础上的合作伙伴的影响评级的协变量包括角和缘上回，而神经相关的活的面部动作单元包括运动皮层和腹侧面部处理区。研究结果表明，面部模仿和情绪感染的不同神经成分。这篇文章是一个讨论会议的一部分问题“Face2face：推进社会互动的科学”。
Viewing a live facial expression typically elicits a similar expression by the observer (facial mimicry) that is associated with a concordant emotional experience (emotional contagion). The model of embodied emotion proposes that emotional contagion and facial mimicry are functionally linked although the neural underpinnings are not known. To address this knowledge gap, we employed a live two-person paradigm (n = 20 dyads) using functional near-infrared spectroscopy during live emotive face-processing while also measuring eye-tracking, facial classifications and ratings of emotion. One dyadic partner, ‘Movie Watcher’, was instructed to emote natural facial expressions while viewing evocative short movie clips. The other dyadic partner, ‘Face Watcher’, viewed the Movie Watcher's face. Task and rest blocks were implemented by timed epochs of clear and opaque glass that separated partners. Dyadic roles were alternated during the experiment. Mean cross-partner correlations of facial expressions (r = 0.36 ± 0.11 s.e.m.) and mean cross-partner affect ratings (r = 0.67 ± 0.04) were consistent with facial mimicry and emotional contagion, respectively. Neural correlates of emotional contagion based on covariates of partner affect ratings included angular and supramarginal gyri, whereas neural correlates of the live facial action units included motor cortex and ventral face-processing areas. Findings suggest distinct neural components for facial mimicry and emotional contagion. This article is part of a discussion meeting issue ‘Face2face: advancing the science of social interaction’.
