人类使用面部线索来传达社会支配和服从。尽管这种社交能力在进化中具有重要意义，但大脑是如何从面部识别社会支配地位的，目前尚不清楚。我们利用事件相关脑电位（ERP）和功能磁共振成像（fMRI）研究了面部线索社会支配知觉的神经机制。参与者通过观察与攻击性相关的面部表情以及表达支配或服从的面部姿势来做出性别判断。ERP证据表明，攻击性相关情绪表达产生的支配感发生在神经加工的早期，而面部姿势产生的社会支配感产生较晚。脑成像结果显示，梭状回、颞上回和舌回的活动与面部姿势对社会支配的感知有关，这些区域的神经反应的大小区分了感知支配和感知顺从。
Humans use facial cues to convey social dominance and submission. Despite the evolutionary importance of this social ability, how the brain recognizes social dominance from the face is unknown. We used event-related brain potentials (ERP) and functional magnetic resonance imaging (fMRI) to examine the neural mechanisms underlying social dominance perception from facial cues. Participants made gender judgments while viewing aggression-related facial expressions as well as facial postures conveying dominance or submission. ERP evidence indicates that the perception of dominance from aggression-related emotional expressions occurs early in neural processing while the perception of social dominance from facial postures arises later. Brain imaging results show that activity in the fusiform gyrus, superior temporal gyrus and lingual gyrus, is associated with the perception of social dominance from facial postures and the magnitude of neural response in these regions differentiates between perceived dominance and perceived submissiveness.
