these mind formations last into adulthood and artists have to train to see and reproduce what's actually there instead of what their brain is throwing up.

There's an easy way to test this with your own mind, you take a simple photograph of a face and do your best to reproduce it with whatever artistic talent you have. You have to give it a solid effort though.

Then you rotate the photograph upside down repeat the process trying to reproduce exactly what you see.

It's like a parlor trick because for most people the upside down image, which doesn't trigger the brain to draw it's idea of a face, comes out looking passably good even if their right side up copy is shite.

I learned this from a drawing book when i was learning to draw and it blew my mind!
