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.
通过对10名婴儿的反复评估，研究了6至26周龄婴儿的扫描模式特征。当婴儿观看两种动态刺激时，使用角膜反射系统记录眼球运动：母亲自然移动的脸和一个抽象刺激物。结果表明，婴儿扫描这些刺激物的方式直到18周后才稳定下来，这比文献中报道的婴儿扫描静态刺激物的年龄稍晚。这种效应在抽象刺激物上尤为明显。从第14周的阶段开始，婴儿根据刺激物特征调整了他们的扫描行为。当扫描母亲面部的视频时，婴儿最常将目光投向嘴巴和眼睛区域。即使在最小的年龄，也没有边缘效应的迹象。
