Infant behavior is viewed in a social-communicative context centered on the phenomenon of spontaneous communication. Symbolic communication is learned and culturally structured, intentional, consists of symbols, and is propositional in content. In contrast, spontaneous communication is innate in both its sending (display) and receiving (preattunement) aspects, non-intentional, consists of signs, and is non-propositional or emotional in content. It underlies infant imitation, interactional synchrony, primary intersubjectivity, emotional empathy, and mirror neurons; and it is associated with oxytocin.

自发交流和婴儿模仿

在以自发交流现象为中心的社会交流环境中观察婴儿行为。符号交流是学习的和文化结构的、有目的的、由符号组成的，并且在内容上是命题的。相比之下，自发交流在其发送（显示）和接收（预调谐）方面都是与生俱来的，非有意的，由符号组成，并且在内容上是非命题或情感的。它是婴儿模仿、互动同步、初级主体间性、情感同理心和镜像神经元的基础；它与催产素有关。
