Individuals with Williams syndrome (WS) and autism are characterized by different social phenotypes but have been said to show similar atypicalities of face-processing style. Although the structural encoding of faces may be similarly atypical in these two developmental disorders, there are clear differences in overall face skills. The inclusion of both populations in the same study can address how the profile of face skills varies across disorders. The current paper explored the processing of identity, eye-gaze, lipreading, and expressions of emotion using the same participants across face domains. The tasks had previously been used to make claims of a modular structure to face perception in typical development. Participants with WS (N=15) and autism (N=20) could be dissociated from each other, and from individuals with general developmental delay, in the domains of eye-gaze and expression processing. Individuals with WS were stronger at these skills than individuals with autism. Even if the structural encoding of faces appears similarly atypical in these groups, the overall profile of face skills, as well as the underlying architecture of face perception, varies greatly. The research provides insights into typical and atypical models of face perception in WS and autism.

探索发育障碍中的面部知觉：来自威廉姆斯综合症和自闭症的证据。

威廉姆斯综合征（WS）和自闭症患者的特征在于不同的社会表型，但据说他们具有相似的面部加工风格非典型性。尽管在这两种发育障碍中人脸的结构编码可能类似地是非典型的，但总体人脸技能仍存在明显差异。在同一研究中将这两个人群纳入研究可以解决面部技能在不同疾病中的差异。当前的论文探索了使用相同的参与者跨越脸部区域来处理身份，注视，唇读和情绪表达的过程。以前曾使用这些任务来声明模块化结构以面对典型开发中的感知。WS（N = 15）和自闭症（N = 20）的参与者可以彼此分离，也可以与一般发育延迟的个体分离，在注视和表情处理领域。WS患者在这些技能上比自闭症患者强。即使在这些组中人脸的结构编码看起来非典型地相似，人脸技能的整体概况以及人脸感知的基础架构也会有很大差异。该研究为WS和自闭症中典型的和非典型的面部感知模型提供了见解。
