Newborns are born into a social environment that dynamically responds to them. Newborn behaviors may not have explicit social intentions but will nonetheless affect the environment. Parents contingently respond to their child, enabling newborns to learn about the consequences of their behaviors and encouraging the behavior itself. Consequently, newborn behaviors may serve both biological and social-cognitive purposes during development.

“什么”比“为什么”更重要——新生儿行为引发社会反应

新生儿出生在一个对他们有动态反应的社会环境中。新生儿行为可能没有明确的社会意图，但仍会影响环境。父母对孩子的反应是偶然的，使新生儿能够了解他们行为的后果并鼓励行为本身。因此，新生儿行为可能在发育过程中同时服务于生物学和社会认知目的。
