Abstract：
Individuals appear to infer others\' psychological characteristics according to facial attractiveness and these psychological characteristics can be classified into two categories in social cognition, that is, warmth and competence. However, which category of psychological characteristic is more associated with face attractiveness and its neural mechanisms have not been explored. To address this, participants were asked to judge others\' warmth and competence traits based on face attractiveness, while their brains were scanned using functional magnetic resonance imaging (fMRI). They also assessed the attractiveness of faces after scanning. Behavioral results showed that the correlation between face attractiveness and warmth ratings was significantly higher than that with competence ratings. fMRI results demonstrated that the dorsomedial prefrontal cortex (dmPFC), temporoparietal junction (TPJ), lateral prefrontal cortex, and lateral temporal lobe were more involved in the warmth task. Moreover, attractiveness ratings were negatively correlated with activation of the dmPFC and TPJ only in the warmth task. Furthermore, the attractiveness ratings were negatively correlated with the defined dmPFC, region related to attractiveness judgment, only in the warmth task. In conclusion, people are more inclined to infer others\' warmth than competence characteristics from face attractiveness, that is, face attractiveness is more associated with warmth than with competence.
摘要：
个人似乎根据面部吸引力推断他人的心理特征，这些心理特征在社会认知中可以分为两类，也就是说,温暖和能力。然而,哪一类心理特征与人脸吸引力的关系更大，其神经机制尚未探讨。为了解决这个问题，参与者被要求根据面部吸引力来判断他人的温暖和能力特征，而他们的大脑使用功能磁共振成像（fMRI）扫描。他们还评估了扫描后面部的吸引力。行为结果表明，面部吸引力与温暖等级之间的相关性显着高于与能力等级之间的相关性。功能磁共振成像结果表明，背内侧前额叶皮质（dmPFC），颞顶交界处（TPJ），外侧前额叶皮质,颞叶和颞叶更多地参与了温暖任务。此外，仅在温暖任务中，吸引力等级与dmPFC和TPJ的激活呈负相关。此外，吸引力评级与定义的dmPFC呈负相关，与吸引力判断相关的区域，只有在温暖的任务。总之,人们更倾向于从面部吸引力中推断他人的温暖而不是能力特征，也就是说,面部吸引力更多地与温暖有关，而不是与能力有关。
