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.When infants are born, their motor skills are very limited, and the fact that they have very little control over their limbs restricts the way in which they are able to explore the world around them. The oculomotor system-unlike other motor systems-approximates its mature state several months after birth. The infant exercises this system every day from birth on. This makes vision one of the most important channels through which babies learn about the world surrounding them. However, during the first months of life, eye movements and visual acuity are also subject to certain constraints. For example, during the first month, eye movements INFANCY, 6(2),
