成人在处理面部信息方面的专业知识需要多年的时间才能发展，并且部分由对面部特征间隔敏感的专门皮质机制（面部处理）介导。在这里，我们表明，从出生到2-6个月大的图形视觉输入的剥夺导致永久性的缺陷，在面部处理。即使经过9年多的康复，接受双侧先天性白内障治疗的患者在区分仅在特征间距上不同的面孔时也严重受损，但在区分仅在个体特征形状上不同的面孔时是正常的。这些发现表明，早期的视觉输入是必要的正常发展的神经结构，将专门用于面部的图形处理。
Adult-like expertise in processing face information takes years to develop and is mediated in part by specialized cortical mechanisms sensitive to the spacing of facial features (configural processing). Here we show that deprivation of patterned visual input from birth until 2–6 months of age results in permanent deficits in configural face processing. Even after more than nine years' recovery, patients treated for bilateral congenital cataracts were severely impaired at differentiating faces that differed only in the spacing of their features, but were normal in distinguishing those varying only in the shape of individual features. These findings indicate that early visual input is necessary for normal development of the neural architecture that will later specialize for configural processing of faces.
