传统的情感理论强调面部表情在情感表达中的重要性，但身体表情也变得越来越重要。在这些实验中，我们验证了这样一个假设，即通过观察情绪化的面部和身体信号可以诱发类似的生理反应，并且对愤怒信号的反应在焦虑的个体中被放大。我们设计了三个实验，参与者将情绪表达从孤立的面部和身体表情以及情绪一致和不一致的面部-身体复合物中分类。研究人员测量了参与者的注视情况，用眼动追踪设备记录了他们的瞳孔大小，用肌电图测量了他们的面部反应。结果支持我们的预测，即面部表情的识别在匹配姿势的背景下得到改善，重要的是，反之亦然。从他们的面部表情来看，观察者似乎对愤怒和恐惧的面部表情表现出消极的情绪（皱眉肌活动增加），对快乐的面部表情表现出积极的情绪（皱眉肌活动增加）。我们预测并发现，来自面部或身体的愤怒和恐惧的线索比快乐的线索吸引了更多的注意力。我们进一步观察到，在焦虑得分高的个体中，愤怒线索引起的反应被放大。总之，我们表明，人们处理身体的情感表达在一个类似的方式作为面部表情和面部和身体的情感信号之间的一致性促进了情感的识别。
Traditional emotion theories stress the importance of the face in the expression of emotions but bodily expressions are becoming increasingly important as well. In these experiments we tested the hypothesis that similar physiological responses can be evoked by observing emotional face and body signals and that the reaction to angry signals is amplified in anxious individuals. We designed three experiments in which participants categorized emotional expressions from isolated facial and bodily expressions and emotionally congruent and incongruent face-body compounds. Participants’ fixations were measured and their pupil size recorded with eye-tracking equipment and their facial reactions measured with electromyography. The results support our prediction that the recognition of a facial expression is improved in the context of a matching posture and importantly, vice versa as well. From their facial expressions, it appeared that observers acted with signs of negative emotionality (increased corrugator activity) to angry and fearful facial expressions and with positive emotionality (increased zygomaticus) to happy facial expressions. What we predicted and found, was that angry and fearful cues from the face or the body, attracted more attention than happy cues. We further observed that responses evoked by angry cues were amplified in individuals with high anxiety scores. In sum, we show that people process bodily expressions of emotion in a similar fashion as facial expressions and that the congruency between the emotional signals from the face and body facilitates the recognition of the emotion.
