The coordination of visual and tactual input in infants

Traditionally it has been taught that “touch teaches vision” in ontogeny. Recent experiments have shown that in judgment situations vision dominates touch, a finding that has been taken to weaken the traditional argument. The force of the finding is vitiated to some extent by the functional dominance of touch. Developmental experiments show that initially in ontogeny vision is functionally dominant, strengthening the case against the traditional argument.
