Converging lines of research suggests that many developmental prosopagnosics (DPs) have impairments beyond face perception, but currently no framework exists to characterize these impaired mechanisms. One potential extra-perceptual deficit is that DPs encode/retrieve faces in a distinct manner from controls that does not sufficiently support individuation. To test this possibility, 30 DPs and 30 matched controls performed an old/new face recognition task while providing confidence ratings, to which a model-based ROC analysis was applied. DPs had significantly reduced recollection compared to controls, driven by fewer ‘high-confidence target’ responses, but intact familiarity. Recollection and face perception ability uniquely predicted objective and subjective prosopagnosia symptoms, together explaining 51% and 56% of the variance, respectively. These results suggest that a specific deficit in face recollection in DP may represent a core aspect of the difficulty in confidently identifying an individual by their face.

多项研究表明，许多发育性面容失认症 (DP) 存在面部感知以外的损伤，但目前尚无框架来描述这些受损机制。一个潜在的超知觉缺陷是 DP 以与不能充分支持个性化的对照不同的方式编码/检索面孔。为了测试这种可能性，30 个 DP 和 30 个匹配的对照执行了旧/新面部识别任务，同时提供置信度评级，并应用了基于模型的 ROC 分析。与对照组相比，DP 的记忆力显着降低，这是由于“高置信度目标”反应较少，但熟悉程度完好无损。记忆力和面部感知能力独特地预测了客观和主观的面盲症症状，分别解释了 51% 和 56% 的方差。这些结果表明，DP 中面部记忆的特定缺陷可能代表了通过面部自信地识别个体的困难的核心方面。
