infants as young as 5 months use size information to perceive depth.

binocular disparity is a powerful cue to depth for these infants.

7-month olds but not 5-month-olds reached for the stimulus that appeared closer because it contained interposition information.

neither infant age group was able to use monocular information cues to depth.
