Developmental prosopagnosia (DP) is a syndrome characterized by lifelong impairment in face recognition in the absence of brain damage. A key question regarding DP concerns which process(es) might be affected to selectively/disproportionally impair face recognition. We present evidence from a group of DPs, combining an overview of previous results with additional analyses important for understanding their pattern of preserved and impaired perceptual abilities. We argue that for most of these individuals, the common denominator is a deficit in (rapid) processing of global shape information. We conclude that the deficit in this group of DPs is not face-selective, but that it may appear so because faces are more visually similar-and recognized at a more fine-grained level-than objects. Indeed, when the demand on perceptual differentiation and visual similarity are held constant for faces and objects, we find no evidence for a disproportionate deficit for faces in this group of DPs.

发育性面容失认的知觉表现模式：深入案例系列

发育性面容失认症 (DP) 是一种综合征，其特征是在没有脑损伤的情况下终生无法识别面部。关于 DP 的一个关键问题是哪些进程可能会受到影响，从而选择性地/不成比例地损害人脸识别。我们提供了一组 DP 的证据，将先前结果的概述与其他分析相结合，这些分析对于理解他们的感知能力的保留和受损模式很重要。我们认为，对于这些人中的大多数人来说，共同点是在（快速）处理全局形状信息方面存在缺陷。我们得出的结论是，这组 DP 中的缺陷不是面部选择性的，但它可能会出现，因为面部在视觉上更相似 - 并且在更细粒度的水平上被识别 - 比对象。确实，
