Perceptions of facial attractiveness are sensitive to emotional expression of the perceived face. However, little is known about whether the emotional expression on the face of another observer of the perceived face may have an effect on perceptions of facial attractiveness. The present study used event-related potential technique to examine social influence of the emotional expression on the face of another observer of the perceived face on perceptions of facial attractiveness. The experiment consisted of two phases. In the first phase, a neutral target face was paired with two images of individuals gazing at the target face with smiling, fearful or neutral expressions. In the second phase, participants were asked to judge the attractiveness of the target face. We found that a target face was more attractive when other observers positively gazing at the target face in contrast to the condition when other observers were negative. Additionally, the results of brain potentials showed that the visual positive component P3 with peak latency from 270 to 330 ms was larger after participants observed the target face paired with smiling individuals than the target face paired with neutral individuals. These findings suggested that facial attractiveness of an individual may be influenced by the emotional expression on the face of another observer of the perceived face.
对面部吸引力的感知对面部表情很敏感。然而，对于被感知面部的另一位观察者脸上的表情是否会对面部吸引力的感知产生影响，我们却知之甚少。本研究使用事件相关电位技术，来检验被感知面部的另一位观察者脸上的表情对面部吸引力感知的社会影响。该实验包括两个阶段。在第一阶段，一张中性目标面孔与两张个体图像配对，这些个体分别以微笑、恐惧或中性表情注视着目标面孔。在第二阶段，要求参与者判断目标面孔的吸引力。我们发现，与其他观察者呈消极表情时相比，当其他观察者以积极表情注视目标面孔时，目标面孔更具吸引力。此外，脑电结果显示，在参与者观察与微笑个体配对的目标面孔后，峰值潜伏期为270至330毫秒的视觉正波成分P3，比观察与中性个体配对的目标面孔后更大。这些发现表明，一个人的面部吸引力可能会受到被感知面部的另一位观察者脸上表情的影响。
