As many of us are visual artists, we’re interested in how our visual intake of light and color is processed and affects our understanding of three-dimensional forms. Our brain makes certain errors in judgment after receiving info from our eyes, which we take advantage of in painting, drawing etc. Spatial illusions can be created with light and shade. Check out this video of “Gardner’s Dragon” below.
You may have heard of this guy called Leibniz, a 17th c. German philosopher who had some pretty kooky theories on metaphysics. Aside from that, in his writings of 1714 called “Monadology” he states this, “We see that animals when, they have the perception of something which they notice and. of which they have had a similar previous perception, are led by the representation of their memory to expect that which was associated in the preceding perception, and they come to have feelings like those which they had before.”
Because we associate this dragon form with a convex face, we assume that’s what we are looking at, even though our brain has received indications from our eyes ( e.g. depth perception from retinal disparity between the eyes) that it’s concave. It’s strange to think that these assumptions can outweigh the signals our eyes are sensing from the light that bounces off it. Seeing is deceiving.
I’ve also included a link to a site with games designed to improve memory and info processing. So far, word bubbles is my favorite. http://www.lumosity.com
