A Comparison of Monocular and Binocular Depth Perception in 5- and 7-Month-Old Infants.
Peer reviewed Peer reviewed
Granrud, Carl E.; And Others – Journal of Experimental Child Psychology, 1984
Compares monocular depth perception with binocular depth perception in five- to seven-month-old infants. Reaching preferences (dependent measure) observed in the monocular condition indicated sensitivity to monocular depth information. Binocular viewing resulted in a far more consistent tendency to reach for the nearer object. (Author)
