Dual-route models of face recognition suggest separate cognitive and affective routes. The predictions of these models were assessed in recognition tasks with unfamiliar, famous, and personally familiar faces. Whereas larger autonomic responses were only triggered for personally familiar faces, priming effects in reaction times to these faces, presumably reflecting cognitive recognition processes, were equal to those of famous faces. Activation of stored structural representations of familiar faces (face recognition units) was assessed by recording the N250r component in event-related brain potentials. Face recognition unit activation increased from unfamiliar over famous to personally familiar faces, suggesting that there are stronger representations for personally familiar than for famous faces. Because the topographies of the N250r for personally and famous faces were indistinguishable, a similar network of face recognition units can be assumed for both types of faces.
人脸识别的双通道模型表明存在独立的认知和情感通道。这些模型的预测在对不熟悉、著名和个人熟悉的面孔的识别任务中进行了评估。虽然只有对个人熟悉的面孔才会引发更大的自主反应，但对这些面孔反应时间的启动效应（大概反映认知识别过程）与对著名面孔的启动效应相同。通过记录事件相关脑电位中的N250r成分来评估熟悉面孔的存储结构表征（人脸识别单元）的激活情况。人脸识别单元的激活从陌生面孔到著名面孔再到个人熟悉的面孔逐渐增加，这表明个人熟悉的面孔比著名面孔有更强的表征。由于个人熟悉面孔和著名面孔的N250r地形图无法区分，因此可以假定这两种类型的面孔具有相似的人脸识别单元网络。
