两个人共同关注同一物体或事件的过程称为联合注意。共同注意和自我、他人和客体之间潜在的三元表征被认为是人类独有的，支持教学、合作和语言学习。尽管在理解共同注意在早期社会发展中的行为重要性方面取得了进展，但对支持婴儿发育中共同注意的大脑底物几乎一无所知。我们使用近红外光谱分析了五个月大婴儿的前额叶皮质在三联体社会互动中的反应。结果表明，即使在五个月大的时候，婴儿也对三元互动很敏感，像成年人一样，当他们与另一个人进行联合注意时，他们会招募一个特定的大脑区域，位于左侧背侧前额叶皮质。这表明，人类婴儿在神经生物学上已经做好了与其他人类分享注意力的准备，这可能为各种独特的人类社会和文化学习过程提供基础。
The process by which two people share attention towards the same object or event is called joint attention. Joint attention and the underlying triadic representations between self, other person and object are thought to be unique to humans, supporting teaching, cooperation and language learning. Despite the progress that has been made in understanding the behavioural importance of joint attention during early social development, almost nothing is known about the brain substrate that supports joint attention in the developing infant. We examined responses in five-month-old infants' prefrontal cortex during triadic social interactions using near-infrared spectroscopy. The results demonstrate that, even by the age of five months, infants are sensitive to triadic interactions and, like adults, they recruit a specific brain region localized in left dorsal prefrontal cortex when engaged in joint attention with another person. This suggests that the human infant is neurobiologically prepared for sharing attention with other humans, which may provide the basis for a wide variety of uniquely human social and cultural learning processes.
