Visual Cliff

The visual cliff is a psychological test given to babies of different species. The visual cliff is exactly what is sounds like; a visual illusion of a cliff. The baby is placed on the side that looks solid, and on the other side of the table is a glass pane with a dropp so that it looks like a cliff. The baby's mother stands across from the cliff and tries to pursuade the baby to cross the cliff to test their depth perception. When a baby first starts to sit, they reach right over the cliff, not noticing the dropp. Once a baby has been sitting for a while they do not readily reach over the cliff. Then when the baby first starts to crawl it readily crawls across the cliff to it's mother. However when a baby has been crawling for a while, he does not crawl over the cliff. This pattern continues for when the baby starts walking. The baby must re-learn depth perception at each stage of development. The baby learns through experience sitting, crawling, walking.
