Visual Cliff Experiment |
||||||
 |
||||||
|
||||||
| Despite his mother’s beckoning, an infant hesitates to cross the “visual cliff”—an apparently steep drop that is actually covered by transparent glass. Psychologists in the 1960s found that most infants 6 to 14 months of age were reluctant to crawl over the cliff, suggesting they had the ability to perceive depth. Most psychologists believe that the ability to perceive depth is partly innate and partly a product of early visual experience. | ||||||
