Test your Brain and Mind with these 9 Classic Optical Illusions

Are the two orange circles of the same size? 

One way to learn more about our brains and minds is to look at how we can trick them–that is, to see how we react to brain teasers and visual illusions.

Quick facts: The brain has two hemispheres, each divided into four lobes. Each lobe is (largely) responsible for different functions. For instance the frontal cortex (in yellow) is responsible for decision making and planning; the temporal lobe (in purple) for language and memory; the parietal lobe (in green) for spatial skills, and the occipital lobe (in red) is entirely devoted to vision: It is thus the place where visual illusions happen..

Below are 9 optical illu­sions that com­bine fun and learn­ing about our visual system. We know you know there is a trick since these are illu­sions… but don’t try to be smarter than your brain; enjoy being surprised!

Visual illusions to tease our brains and minds


Why Optical Illusions Like These Make Your Brain Go Haywire (Wired):

“University of Bristol researchers discovered this illusion in the early 1970s while looking at the tiled wall of a café. Hence the name, Café Wall Illusion. The gray lines in between the rows of white and black squares seem to converge, but they are actually parallel. Your brain, overwhelmed by the intense and closely-spaced black-and-white contrasts, sees the gray lines as part of the tile either above or below it. The lines end up appearing higher on alternating sides, creating the trapezoidal illusion.”
