面部吸引力的判断在很大程度上取决于面部结构的特征和观察者的个性。然而，人们对背景差异对面部吸引力的影响知之甚少。在这项脑电研究中，参与者判断了单独呈现的面孔或与吸引力较高的面孔(HAF)或吸引力较低的面孔(LAF)配对呈现的面孔的吸引力。当目标面孔与HAFs或LAF配对呈现时，目标面孔的吸引力判断分数显著高于单独呈现时，并且伴随着较大的晚期积极复合体。这些结果表明，背景面孔提高了目标面孔的吸引力判断。微观状态分析表明，状态3的全局场强(GFP)与HAF条件下的吸引力判断显著相关，而状态2的GFP与LAF条件下的吸引力判断显著相关。有趣的是，状态2的GFP在自恋与面孔吸引力判断之间的关系中起到了中介作用。来源定位分析表明，状态3和状态2激活了参与情绪加工的额上回和额中回。我们的发现表明，面部吸引力可以通过与其他面孔的上下文比较来增强，这取决于观察者的个性。利用脑电(EEG)测量了高吸引力和低吸引力人脸配对时大脑的时空动态变化。我们的结果显示，当一张脸与其他面孔一起出现时，人们会认为它比单独出现时更有吸引力。我们的发现有助于理解面部吸引力的神经认知机制和过程。
Facial attractiveness judgment largely depends on the characteristics of the facial structure and the personality of the observer. However, little is known about the influence of contextual variations on facial attractiveness. In this electroencephalogram study, participants judged the attractiveness of faces presented individually or in pairs with either a higher‐attractive face (HAF) or lower‐attractive face (LAF). The attractiveness judgment rating of the target face was significantly higher when presented in pairs with HAFs or LAFs than when presented individually and was accompanied by a larger late positive complex. These results suggest that contextual faces enhance the attractiveness judgment of target faces. Microstate analyses revealed that the global field power (GFP) of state 3 was significantly correlated with the attractiveness judgment in the HAF condition whereas the GFP of state 2 was significantly correlated with the attractiveness judgment in the LAF condition. Interestingly, the GFP of state 2 mediated the relationship between narcissism and facial attractiveness judgment in the context of LAFs. Source location analyses showed that states 3 and 2 activated the superior and middle frontal gyrus, which are involved in emotion processing. Our findings suggest that facial attractiveness can be enhanced by contextual comparison with other faces, subject to personality of the observer. By using the electroencephalogram (EEG), the spatiotemporal dynamics of the brain were measured when faces were paired with high and low attractiveness faces. Our results show that the face was judged more attractive than it presents alone when it appears with others faces. Our findings contribute to the understanding of neurocognitive mechanisms and processes of facial attractiveness.
