Individuals differ in how they judge facial attractiveness. However, little is known about the role of arousal level and gender differences in individuals' facial attractiveness judgments.
We used resting-state electroencephalogram (EEG) to investigate this issue. A total of 48 men (aged 22.5 ± 3.03 years [mean ± SD], range: 18-30 years) and 27 women (aged 20.3 ± 2.03 years [mean ± SD], range: 18-25 years) participated in the experiment. After the EEG was collected, participants were instructed to complete a facial attractiveness judgment task. Connectome-based predictive modeling was used to predict individual judgment of facial attractiveness.
Men with high arousal judged female faces as more attractive (M = 3.85, SE = 0.81) than did men with low arousal (M = 3.33, SE = 0.81) and women (M = 3.24, SE = 1.02). Functional connectivity of the alpha band predicted judgment of female facial attractiveness in men but not in women. After controlling for the age and variability, the prediction effect was still significant.
Our results provide neural evidence for the enhancement of the judgment of facial attractiveness in men with high arousal levels, which supports the hypothesis that individuals' spontaneous arousal contributes to variations in facial attractiveness preferences.
个体对面部吸引力的判断存在差异。然而，对于个体在面部吸引力判断中的唤醒水平和性别差异的作用知之甚少。
我们使用静息态脑电图（EEG）来研究这个问题。共有 48 名男性（年龄 22.5±3.03 岁[均值±标准差]，范围：18-30 岁）和 27 名女性（年龄 20.3±2.03 岁[均值±标准差]，范围：18-25 岁）参与了实验。在采集完 EEG 后，参与者被指示完成面部吸引力判断任务。连接组预测模型被用于预测个体对面部吸引力的判断。
高唤醒水平的男性（M=3.85，SE=0.81）比低唤醒水平的男性（M=3.33，SE=0.81）和女性（M=3.24，SE=1.02）认为女性面孔更有吸引力。alpha 波段的功能连接可以预测男性对女性面部吸引力的判断，但不能预测女性的判断。在控制年龄和变异性后，预测效果仍然显著。
我们的结果为高唤醒水平男性对面部吸引力判断的增强提供了神经学证据，支持了个体自发唤醒有助于面部吸引力偏好变化的假设。
