外向性的人格特质与控制对奖励线索的敏感性并产生接近行为的大脑系统网络有关，但很少有人知道外向者的神经回路是否对社会刺激特别敏感，因为他们更喜欢社会参与。利用事件相关电位（ERP）的方法，本研究表明，外倾性维度的变化与社会刺激引起的注意分配增强的程度有关。具体来说，较高的分数外倾被认为是与较高的幅度的P300组成部分的ERPs引起的人脸。这一发现表明，社会刺激具有增强的动机意义的个人特点是高外倾性，个性的个体差异与有意义的个体差异的神经反应社会刺激。
The personality trait of extraversion has been linked to the network of brain systems controlling sensitivity to cues of reward and generating approach behavior in response, but little is known about whether extraverts’ neural circuits are especially sensitive to social stimuli, given their preference for social engagement. Utilizing event-related potential (ERP) methodology, this study demonstrates that variation on the extraversion dimension is associated with the extent to which social stimuli evoke enhanced allocation of attention. Specifically, higher scores on extraversion were found to be associated with higher amplitudes of the P300 component of the ERPs elicited by human faces. This finding suggests that social stimuli carry enhanced motivational significance for individuals characterized by high extraversion, and that individual differences in personality are related to meaningful individual differences in neural responses to social stimuli.
