It was shown previously that infants who have neither reached nor crawled discriminate changes in spatial position on the basis of cues other than the projective size of objects displaced in space. It is now shown that binocular vision is not necessary for discrimination and that pictorial cues are not sufficient for discrimination. Parallax variables provide the information used by such infants for the discrimination of size and distance.
