Human infants are social by nature. Early behaviors taken as evidence of an innate desire to connect with others generally include eye contact, smiles, and positive vocalizations. Studies have shown that, as infants mature, they begin to alternate gaze between objects of interest and their social partners (joint attention), and show signs that some people are special to them by becoming distressed when separated from them (attachment). In this article, we seek to highlight less frequently studied ways that infants and young children show their desire to connect and communicate with others. To do so, we draw on studies of infants in underrepresented communities, interviews with parents of autistic children, and a recent study of interactions between autistic adults.

延伸社会：拓宽社会行为指标

人类婴儿天生就是社交的。早期行为被视为与生俱来的与他人交往的渴望的证据，通常包括眼神交流，微笑和积极发声。研究表明，随着婴儿的成熟，他们开始在感兴趣的对象和他们的社交伙伴之间交替注视（共同关注），并显示出一些人对他们很特别，因为与他们分离时会感到困扰（依恋）。在本文中，我们力求突出研究频率较低的婴幼儿表现出与他人建立联系和交流的愿望的方式。为此，我们利用对代表性不足的社区中婴儿的研究，对自闭症儿童父母的访谈以及对自闭症成年人之间互动的最新研究。
