In the kitten carousel study by Held and Hein (1963), two kittens were initially deprived of visual input until they could locomote and then received identical visual stimulation in a carousel apparatus. Critically, one kitten was "active" and allowed to move about on its own, while the second kitten was "passive" and pulled around the carousel by the first kitten. What were the key findings of this study, and how do they relate to what you have learned about perceptual development in infants?
