The present study investigated the influence social factors upon the neural processing of faces of other races using event-related potentials. A multi-tiered approach was used to identify face-specific stages of processing, to test for effects of race-of-face upon processing at these stages and to evaluate the impact of social contact and individuating experience upon these effects. The results showed that race-of-face has significant effects upon face processing, starting from early perceptual stages of structural encoding, and that social factors may play an important role in mediating these effects.
本研究使用事件相关电位来探究社会因素对其他种族面孔神经加工的影响。采用了一种多层次的方法来识别面孔加工的特定阶段，测试面孔种族对这些阶段加工的影响，并评估社会接触和个体化经历对这些影响的作用。结果表明，面孔种族从结构编码的早期感知阶段就对面孔加工有显著影响，并且社会因素可能在调节这些影响方面发挥重要作用。
