Considerable research has focused on how people derive information about others’ social category memberships from their faces. Theoretical models posit that early extraction of task-relevant information from a face should determine the efficiency with which that face is categorized, but evidence supporting this idea has been elusive. Here, we used a novel trial-level data analytic approach to examine the relationship between two event-related potential components—the P2, indexing early attention to category-relevant information, and the P3, indexing stimulus evaluation—and the speed of overt categorization judgments. As predicted, a larger face-elicited P2 on a particular trial was associated with faster overt race or gender categorization of that face. Moreover, this association was mediated by P3 latency, indicating that extraction of more category-relevant information early in processing facilitated stimulus evaluation. These findings support continuous flow models of information processing and the long-theorized functional significance of face-elicited neurophysiological responses for social categorization.

人脸社会分类过程中大脑和行为的功能耦合
相当多的研究集中在人们如何从他们的面孔中获取有关其他人的社会类别成员资格的信息。理论模型假设,从面部早期提取任务相关信息应该决定面部分类的效率,但支持这一想法的证据一直难以捉摸。在这里,我们使用了一种新颖的试验级数据分析方法来检查两个与事件相关的潜在组成部分之间的关系——P2,将早期注意力指向与类别相关的信息,以及 P3,索引刺激评估——以及公开分类的速度判断。正如预测的那样,特定试验中较大的面部引起的 P2 与该面部更快的公开种族或性别分类相关。此外,这种关联是由 P3 潜伏期介导的,表明在处理早期提取更多与类别相关的信息有助于刺激评估。这些发现支持信息处理的连续流模型以及面部引发的神经生理反应对社会分类的长期理论功能意义。
