TL;DR
Accuracy was barely affected, but the reach trajectories indicated that infants switched from a miss path to a hit path in midcourse, suggesting that visually directed reaching was operative in the youngest infants and that it improved with age.
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.
