Abstract
This investigation measured the accuracy of reaching in infants wearing 30-diopter prisms. Infants varied in age from 4 to 10 months. Although accuracy was barely affected, the reach trajectories indicated that infants switched from a miss path to a hit path in midcourse. There was some evidence to support the view that visually directed reaching was operative in the youngest infants and that it improved with age.
