虽然面部处理被认为是人类正常面部感知的标志，但有充分的证据表明，处理面部成分也有助于面部识别和识别。事实上，大多数当代模型都采用双重代码观点，其中人脸识别依赖于对各个人脸组件以及它们之间的空间关系的分析。我们探讨了处理面配置和内部面组件之间的相互作用，通过记录N170，一个事件相关的潜在组件，体现了早期检测的面孔。在一个强大的N170的效果引起的线条画的示意性的面孔相比，线条画的示意性的对象，没有N170的效果被发现，如果一对小物体取代的眼睛示意性的面孔。然而，如果用一对缩小的脸代替眼睛，N170效应就恢复了。额外的实验排除了一个解释的基础上，小型化的脸吸引注意力的独立于他们的位置在一个类似的脸配置，并表明，全球和本地的脸的特点竞争处理资源时，在冲突。结果进行了讨论，因为它们涉及到正常和异常的脸处理。
Although configural processing is considered a hallmark of normal face perception in humans, there is ample evidence that processing face components also contributes to face recognition and identification. Indeed, most contemporary models posit a dual-code view in which face identification relies on the analysis of individual face components as well as the spatial relations between them. We explored the interplay between processing face configurations and inner face components by recording the N170, an event-related potential component that manifests early detection of faces. In contrast to a robust N170 effect elicited by line-drawn schematic faces compared to line-drawn schematic objects, no N170 effect was found if a pair of small objects substituted for the eyes in schematic faces. However, if a pair of two miniaturized faces substituted for the eyes, the N170 effect was restored. Additional experiments ruled out an explanation on the basis of miniaturized faces attracting attention independent of their location in a face-like configuration and show that global and local face characteristics compete for processing resources when in conflict. The results are discussed as they relate to normal and abnormal face processing.
