Prosopagnosia is currently viewed within the constraints of two competing theories of face recognition, one highlighting the analysis of features, the other focusing on configural processing of the whole face. This study investigated the role of feature analysis versus whole face configural processing in the recognition of facial expression. A prosopagnosic patient, SC made expression decisions from whole and incomplete (eyes-only and mouth-only) faces where features had been obscured. SC was impaired at recognizing some (e.g., anger, sadness, and fear), but not all (e.g., happiness) emotional expressions from the whole face. Analyses of his performance on incomplete faces indicated that his recognition of some expressions actually improved relative to his performance on the whole face condition. We argue that in SC interference from damaged configural processes seem to override an intact ability to utilize part-based or local feature cues.
目前，面孔失认症是在两种相互竞争的面部识别理论的框架内被看待的，一种强调特征分析，另一种侧重于对面部整体的构型处理。本研究调查了特征分析与面部整体构型处理在面部表情识别中的作用。一名面孔失认症患者SC，从特征被遮挡的完整和不完整（仅眼睛和仅嘴巴）面部做出表情判断。SC在识别某些（如愤怒、悲伤和恐惧）但不是所有（如快乐）来自完整面部的情绪表情时存在障碍。对他在不完整面部上的表现分析表明，他对某些表情的识别相对于他在完整面部条件下的表现实际上有所提高。我们认为，在SC中，受损构型过程的干扰似乎压倒了利用基于部分或局部特征线索的完整能力。
