虽然在某些情况下，减少一个人对他人痛苦的情绪反应可能是合适的，但观察者的情绪表达对他们对他人痛苦反应的影响仍然没有得到很好的理解。在本研究中，我们研究了情绪调节策略表达抑制如何影响他人对疼痛的反应。基于先前对表达抑制和疼痛共情的研究结果，我们假设对疼痛表情面孔的表达抑制会减少负面情绪、替代性疼痛或两者的神经表征。为了验证这一点，我们将两个多变量模式分析（MVPA）衍生的神经签名应用于我们的数据，图片诱导的负面情绪签名（PINES）和面部表情诱导的替代性疼痛的神经签名。在60名健康人的样本中，我们发现，观看痛苦表情的面孔增加了负面情绪和替代性疼痛的神经表征。然而，对痛苦面孔的表达抑制只减少了消极情绪的神经表征。PINES对疼痛面孔的反应与参与者的特质水平的同理心和疼痛面孔的感知不愉快有关，这为消极情绪和疼痛同理心的神经表征之间的联系提供了支持。研究结果表明，抑制一个人的面部表情，以回应他人的痛苦的后果可能是减少在情感方面的同情，但不是替代性疼痛本身的经验。
Although there are situations where it may be appropriate to reduce one’s emotional response to the pain of others, the impact of an observer’s emotional expressivity on their response to pain in others is still not well understood. In the present study, we examined how the emotion regulation strategy expressive suppression influences responses to pain in others. Based on prior research findings on expressive suppression and pain empathy, we hypothesized that expressive suppression to pain expression faces would reduce neural representations of negative emotion, vicarious pain, or both. To test this, we applied two multivariate pattern analysis (MVPA)-derived neural signatures to our data, the Picture Induced Negative Emotion Signature (PINES) and a neural signature of facial expression induced vicarious pain. In a sample of 60 healthy individuals, we found that viewing pain expression faces increased neural representations of negative emotion and vicarious pain. However, expressive suppression to pain faces reduced neural representations of negative emotion only. Providing support for a connection between neural representations of negative emotion and pain empathy, PINES responses to pain faces were associated with participants’ trait-level empathy and the perceived unpleasantness of pain faces. Findings suggest that a consequence of suppressing one’s facial expressions in response to the pain of others may be a reduction in the affective aspect of empathy but not the experience of vicarious pain itself.
