ABSTRACT Typical face perception is mediated by holistic processing (i.e., the simultaneous integration of face parts into a whole representation). People with Acquired Prosopagnosia (AP), who have lost the ability to recognise faces after a brain lesion, should thus show atypical holistic coding. Our aim is to use the composite-face effect (CFE) as a measure of holistic processing in ST, a 48-year-old woman with AP but normal recognition of facial expressions of emotions, and matched healthy control participants. Two experiments examining the CFE for identity (Experiment 1) and for expression of emotions (Experiment 2) were conducted. Contrary to controls, in both experiments, ST showed an atypical (i.e., reversed) CFE, thus suggesting altered holistic mechanisms affecting both components of perceptual judgement. Results also suggest that normal facial expression recognition is achievable even with holistic processing difficulties, possibly through compensatory, part-based, mechanisms.

一例获得性面容失认症中面部身份和表情的非典型整体处理

摘要 典型的人脸感知是由整体处理（即，将人脸部分同时整合为整体表示）介导的。患有获得性面容失认症 (AP) 的人在脑部损伤后失去识别面部的能力，因此应该表现出非典型的整体编码。我们的目标是使用复合面部效应 (CFE) 作为 ST 的整体处理的衡量标准，一名 48 岁的女性患有 AP，但对情绪的面部表情识别正常，并且匹配的健康对照参与者。进行了两个实验，检查 CFE 的身份（实验 1）和情绪表达（实验 2）。与对照相反，在两个实验中，ST 都表现出非典型（即反向）CFE，因此表明影响感知判断的两个组成部分的整体机制发生了改变。
