We used eye-tracking to examine 4.5- to 12.5-month-old infants' ( = 92) eye-movements during 3-s presentations of upright and inverted faces. Scanning of inverted faces was statistically indistinguishable at 4.5, 6.5, 8, and 12.5 months of age; at each of these ages infants disproportionately scanned the region containing the eyes. Scanning of upright faces changed over this age range. When viewing upright faces, 4.5-month-old and 6.5-month-old infants focused disproportionately on the region containing the eyes, whereas 12.5-month-old and 8-month-old infants distributed looking more broadly, scanning more of the internal area of the faces. These results are consistent with other observed developmental differences in face processing, and provide insight into how moment-to-moment face processing changes during infancy.
我们使用眼动追踪技术，在向4.5至12.5个月大的婴儿（ = 92）展示正立和倒置面孔的3秒钟时间内，检查他们的眼动情况。在4.5、6.5、8和12.5个月大时，对倒置面孔的扫描在统计学上没有差异；在每个年龄段，婴儿对包含眼睛的区域进行了不成比例的扫描。在这个年龄范围内，对正立面孔的扫描发生了变化。当观看正立面孔时，4.5个月大和6.5个月大的婴儿不成比例地将注意力集中在包含眼睛的区域，而12.5个月大和8个月大的婴儿则更广泛地分布注视点，扫描面孔内部更多区域。这些结果与其他观察到的面部处理发育差异一致，并为婴儿期瞬间面部处理如何变化提供了见解。
