通过对10名婴儿的重复评估，研究了6至26周龄婴儿的扫描模式特征。当婴儿看两个动态刺激时，使用角膜反射系统记录眼球运动：他们母亲自然移动的脸和抽象的刺激。结果表明，婴儿扫描这些刺激的方式在18周后才稳定下来，这略晚于文献中报道的婴儿扫描静态刺激的年龄。这种效应在抽象刺激中尤为突出。从14周的会议上，婴儿适应他们的扫描行为的刺激特性。当浏览母亲的面部视频时，婴儿最常将目光投向嘴和眼睛区域。即使在最年轻的时候，也没有迹象表明存在边缘效应。
The characteristics of scanning patterns between the ages of 6 and 26 weeks were investigated through repeated assessments of 10 infants. Eye movements were recorded using a corneal-reflection system while the infants looked at 2 dynamic stimuli: the naturally moving face of their mother and an abstract stimulus. Results indicated that the way infants scanned these stimuli stabilized only after 18 weeks, which is slightly later than the ages reported in the literature on infants' scanning of static stimuli. This effect was especially prominent for the abstract stimulus. From the 14-week session on, infants adapted their scanning behavior to the stimulus characteristics. When scanning the video of their mother's face, infants directed their gaze at the mouth and eye region most often. Even at the youngest age, there was no indication of an edge effect.
