处理面部表情是社会互动的重要组成部分，特别是对语言发育前的婴儿。在成年人和猴子中，这一过程涉及运动系统，其中神经匹配机制被认为可以将自我和他人产生的面部表情结合起来。在这里，我们使用脑电图来证明招聘的人类运动系统在观察和执行的面部表情在9个月大的婴儿，暗示这个系统在面部表情处理从很小的时候。值得注意的是，早期的视频记录的母婴互动的检查支持的共同的，但尚未测试，假设母亲的镜像婴儿面部表情是中央的发展神经匹配机制，这些手势。具体来说，在产后两个月的母亲反映婴儿面部表情的程度预测婴儿运动系统的活动，在9个月的相同的表情观察。这表明，母亲的镜像加强了面部表情的视觉和运动表征之间的映射，这增加了婴儿对早期社会环境中特别相关线索的神经敏感性。
Processing facial expressions is an essential component of social interaction, especially for preverbal infants. In human adults and monkeys, this process involves the motor system, with a neural matching mechanism believed to couple self- and other-generated facial gestures. Here, we used electroencephalography to demonstrate recruitment of the human motor system during observation and execution of facial expressions in nine-month-old infants, implicating this system in facial expression processing from a very young age. Notably, examination of early video-recorded mother-infant interactions supported the common, but as yet untested, hypothesis that maternal mirroring of infant facial gestures is central to the development of a neural matching mechanism for these gestures. Specifically, the extent to which mothers mirrored infant facial expressions at two months postpartum predicted infant motor system activity during observation of the same expressions at nine months. This suggests that maternal mirroring strengthens mappings between visual and motor representations of facial gestures, which increases infant neural sensitivity to particularly relevant cues in the early social environment.
