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.
二维和三维图形对4周龄和8周龄婴儿的视觉行为产生了不同的影响。4周龄的婴儿注视凹陷的三维图形的时间比二维图形更长，但扫视方式并无差异。8周龄的婴儿对一种刺激的注视时间并不比另一种刺激更长，但他们扫视凸起的三维图形的方式与二维等效图形不同。对于所有刺激和两个年龄组，刺激的吸引力与其扫视方式之间存在关联；对刺激最感兴趣的婴儿以最小的眼球运动来观察它们。
