Face recognition is often considered to be a modular (encapsulated) function. This annotation supports the proposal that faces are special, but suggests that their identification makes use of general-purpose cortical systems that are implicated in high-level vision and also in memory and learning more generally. These systems can be considered to function within two distinct cortical streams: a medial stream (for learning and salience of faces encountered) and a lateral stream (for distributed representations of visual properties and identities of faces). Function in the lateral stream, especially, may be critically dependent on the normal development of magnocellular vision. The relevance of face recognition anomalies in three developmental syndromes (Autism, Williams syndrome, and Turner syndrome) and the two-route model sketched above is considered.
人脸识别通常被认为是一种模块化（封装式）功能。这一注解支持了面孔具有特殊性的观点，但也表明对面孔的识别利用了涉及高级视觉以及更广泛地涉及记忆和学习的通用皮质系统。这些系统可被认为在两个不同的皮质流中发挥作用：一个内侧流（用于学习所遇到面孔的显著性）和一个外侧流（用于面孔视觉属性和身份的分布式表征）。特别是外侧流中的功能可能严重依赖于大细胞视觉的正常发育。本文考虑了三种发育综合征（自闭症、威廉姆斯综合征和特纳综合征）中人脸识别异常的相关性以及上述双路径模型。
