The tendency to express emotions non-verbally is positively related to perception of emotions in oneself. This study examined its relationship to perception of emotions in others. In 40 healthy adults, EEG theta synchronization was used to indicate emotion processing following presentation of happy, angry, and neutral faces. Both positive and negative expressiveness were associated with higher emotional sensitivity, as shown by cortical responses to facial expressions during the early, unconscious processing stage. At the late, conscious processing stage, positive expressiveness was associated with higher sensitivity to happy faces but lower sensitivity to angry faces. Thus, positive expressiveness predisposes people to allocate fewer attentional resources for conscious perception of angry faces. In contrast, negative expressiveness was consistently associated with higher sensitivity. The effects of positive expressiveness occurred in cortical areas that deal with emotions, but the effects of negative expressiveness occurred in areas engaged in self-referential processes in the context of social relationships.
非言语表达情感的倾向与对自身情感的感知呈正相关。本研究考察了它与对他人情感感知的关系。在 40 名健康成年人中，使用 EEG theta 同步来指示呈现快乐、愤怒和中性面孔后对情绪的处理。积极和消极的表达能力都与更高的情绪敏感性相关，这表现为在面部表情的早期、无意识处理阶段，大脑皮层对表情的反应。在后期、有意识处理阶段，积极的表达能力与对快乐面孔的敏感性更高相关，但对愤怒面孔的敏感性较低。因此，积极的表达能力使人在有意识地感知愤怒面孔时分配较少的注意力资源。相比之下，消极的表达能力始终与更高的敏感性相关。积极表达能力的影响发生在处理情绪的大脑区域，而消极表达能力的影响发生在与社会关系相关的自我参照过程中涉及的区域。
