Infant visual scanning of two- and three-dimensional forms.
2- and 3-dimensional forms affected 4- and 8-week-old infant visual behavior differently, 4-week-old infants fixated a recessed 3-dimensional form more than a 2-dimensional form but did not scan it differently. 8-week-old infants did not look more at 1 stimulus than another but scanned a raised 3-dimensional form differently than a 2-dimensional equivalent. For all stimuli and both age groups, there was a relation between attractiveness of stimuli and how they were scanned; babies who were most attracted to stimuli inspected them with the smallest eye movements.
