Do you see gray dots at the intersections of the white lines?Ĭontrast your answers with the ones below, and learn about what was going on in your brain and mind while you experienced each of these classic optical illusions. Are the two horizontal lines of the same length? Are the two orange circles of the same size?Ħ. Are the horizontal lines straight or crooked? Are the squares inside the blue and yellow squares all the same color?
(You’ll find answers and explanations at the end of the article)ġ. We know you know there is a trick since these are illusions… but don’t try to be smarter than your brain. 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.īelow are 9 optical illusions that combine fun and learning about our visual system.
Each lobe is (largely) responsible for different functions. The brain has two hemispheres, each divided into four lobes.
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. Are the two orange circles of the same size?
