The present study investigated the still-face response to a female stranger in newborn, 1.5-, and 3-month-old infants. The results revealed that 1.5- and 3-month-olds, but not newborns, reliably decreased their visual attention and positive affect when the interaction partner became unresponsive during the still-face period.
本研究调查了新生儿、1.5个月大婴儿和3个月大婴儿对陌生女性的静止脸反应。结果显示，在静止脸阶段，当互动伙伴变得无反应时，1.5个月和3个月大的婴儿会可靠地减少视觉注意力和积极情绪，但新生儿不会。
