Although we know much about the development of face processing, we know considerably less about the development of body knowledge—despite bodies also being significant sources of social information. One set of studies indicated that body structure knowledge is poor during the 1st year of life and spawned a model that posits that, unlike the development of face knowledge, which benefits from innate propensities and dedicated learning mechanisms, the development of body knowledge relies on general learning mechanisms and develops slowly. In this article, we review studies on infants' knowledge about the structure of bodies and their processing of gender and emotion that paint a different picture. Although questions remain, a general social cognition system likely engenders similar trajectories of development of knowledge about faces and bodies, and may equip developing infants with the capacity to obtain socially critical information from many sources.

婴儿期身体结构知识的发展。

尽管我们对人脸处理的发展了解很多，但对身体知识的发展了解却很少，尽管身体也是社会信息的重要来源。一组研究表明，身体结构知识在生命的第一年是很差的，并产生了一个模型，该模型提出，与面部知识的发展不同，它得益于先天的倾向和专门的学习机制，而身体知识的发展则依赖于一般性知识。学习机制并发展缓慢。在本文中，我们回顾了关于婴儿关于身体结构及其性别和情感处理的知识的研究，这些知识描绘了另一幅图画。尽管问题仍然存在，但是一般的社会认知系统可能会产生关于面孔和身体的知识发展的类似轨迹，
