Child Looking Patterns: A Sudden Change in Visual Information Pick-Up at 32 Month of Age.
Jacobsen, Karl; And Others
This study examined infants' change in visual information pick-up, from an infant-like stimulus-locked visual scanning pattern to an adult-like cognitive control of visual information pick-up. Subjects were 21 children between 25 and 42 months of age. Eye movements were videotaped in a preferential looking situation and later analyzed as still pictures. Results revealed a change in the visual looking pattern occurring during a brief period between 32 and 33 months of age. In younger children, presentation of a peripheral stimulus elicited a corresponding saccadic eye movement followed by a 2- to 3-second period of stimulus-locked attention. In older children, the initial stimulus fixation lasted less than 0.1 seconds and was followed by an eye movement in the opposite direction, initiating a search of the visual scene. This difference indicates a developmental change in the cognitive control of information pick-up. (MM)
