From the beginning of life, face and language processing are crucial for establishing social communication. Studies on the development of systems for processing faces and language have yielded such similarities as perceptual narrowing across both domains. In this article, we review several functions of human communication, and then describe how the tools used to accomplish those functions are modified by perceptual narrowing. We conclude that narrowing is common to all forms of social communication. We argue that during evolution, social communication engaged different perceptual and cognitive systems—face, facial expression, gesture, vocalization, sound, and oral language—that emerged at different times. These systems are interactive and linked to some extent. In this framework, narrowing can be viewed as a way infants adapt to their native social group.

关于人脸处理、语言处理和发展过程中缩小之间的联系。

从生命的开始，面部和语言处理对于建立社会交流至关重要。对面部和语言处理系统开发的研究已经产生了跨越两个领域的感知缩小等相似之处。在这篇文章中，我们回顾了人类交流的几个功能，然后描述了用于完成这些功能的工具是如何通过感知缩小来修改的。我们得出结论，缩小范围对于所有形式的社会交流都是常见的。我们认为，在进化过程中，社会交流涉及不同时期出现的不同感知和认知系统——面部、面部表情、手势、发声、声音和口头语言。这些系统在某种程度上是互动的并相互关联的。在这个框架中，
