We present an extensive investigation (24 experiments) of a new case of prosopagnosia following right unilateral damage, GG, with the aim of addressing two classical issues: (1) Can a visual recognition impairment truly be specific to faces? (2) What is the nature of acquired prosopagnosia? We show that GG recognizes nonface objects perfectly and quickly, even when it requires fine-grained analysis to individualize these objects. He is also capable of perceiving objects and faces as integrated wholes, as indicated by normal Navon effect, 3D-figures perception and perception of Mooney and Arcimboldo face stimuli. However, the patient could not perceive individual faces holistically, showing no inversion, composite, or whole-part advantage effects for faces. We conclude that an occipito-temporal right hemisphere lesion may lead to a specific impairment of holistic perception of individual items, a function that appears critical for normal face recognition but not for object recognition.
我们呈现了一项广泛的研究（24 个实验），探讨了右侧单侧损伤后出现的一种新的面孔失认症病例 GG，旨在解决两个经典问题：（1）视觉识别障碍真的可以专门针对面孔吗？（2）获得性面孔失认症的本质是什么？我们表明，GG 可以完美而快速地识别非面孔物体，即使需要对这些物体进行精细的分析才能对其进行个体化。他还能够将物体和面孔视为完整的整体，这表明他的 Navon 效应、3D 图形感知和 Mooney 和 Arcimboldo 面孔刺激的感知正常。然而，患者无法整体感知单个面孔，对面孔的倒置、组合或整体-部分优势效应没有反应。我们得出结论，右侧枕颞叶半球损伤可能导致对单个项目的整体感知特异性损伤，这种功能对于正常的面孔识别至关重要，但对于物体识别则不然。
