Age differences in eye movements during video viewing
This study examined eye movements during video viewing across a wide age range and establishes eye-tracking as a useful tool for studying age differences in processing of video. One-year-olds, 4-year-olds, and adults watched 20 minutes of Sesame Street, a program produced for young children. Results suggest that while the underlying mechanisms controlling eye movements during video viewing are relatively stable across these age groups, particular patterns of eye movements differed in important ways. Specifically, infants' fixations were more variable and less responsive to content boundaries than were those of older children and adults. Results have implications for the extent to which very young children comprehend and can learn from video.
