Someone called optical illusions–“Brain Failures.”. Forgot who to credit.
Your brain takes shortcuts with image processing that can be exposed with optical illusions.
Different illusions can reveal specific structures or processing that can be tricked.
Of course these short cuts the brain takes in everyday life are totally fine; only when given a specific illusion are issues revealed.
Some illusions are based on 90⁰ angles of the western world. The Ames Room and Ames Window as examples. These illusions don’t work as well when tested on people who live in tribal societies without many Right Angles.
