    There's some controversy about this. All we know is that when babies have a little crawling experience they avoid crawling over the experimental fake cliff.



    The visual cliff experiment by Eleanor Gibson and R.D. Walk in 1960 demonstrated the response by human and animal infants to a visual obstacle.

    “It’s a glass table, and on one side there’s a checkboard pattern surface right under the glass. The other side of the table the patterned surface is way down on the floor. so visually it looks like a big three-foot drop-off,” Adolphs says. The experiment became a shaky foundation for the myth that crawling innately teaches us to fear heights.

    The visual cliff, however, was a better test of the infant’s depth perception — and not their fear of heights. Watch closely, and you’ll notice that the babies — new crawlers — aren’t particularly scared and will crawl right onto the glass. But a baby with several weeks of crawling experience will begin to refuse to crawl over the drop-off, but will use their arms to feel their way through the obstacle. And they do so without fearful emotion.
