VISUAL CLIFF

I just saw a video wherein the kid was petrified by fear, unable to cross a transparent glass for he believed that it was a danger to him. Of course, his parents documented the incident before reaching out to a kid. (very usual phenomena these days that I think will make our race extinct, kidding)

The idea of depth perception of the kid amazes me. It actually reminds me of the visual cliff study of Gibson and Walk when they tested the depth perception of human infants (babies who just learned to crawl). They found out that adjusting the visual cliff as deep made the crawlers hesitate to crawl on a plexiglass toward their parents. It's amazing!

What makes this study amazing?
Imagine that 6 to 14 months old infants were never taught about the depth perception. They just knew that it's dangerous to cross a simulated cliff (believing it was an actual cliff).

Hence, the idea of inherent knowledge was somehow validated.  But I want to make it clear, nature and nurture are both vital. It works hand in hand.
