Optical illusion IQ test: Spot the smiling face in this crowd of frowning people in 9 seconds
Think you have the eyes of a hawk? Ever thought you might have a little more, like a heightened sense of perception and an above-average IQ? According to experts at MIT, our brains process images in just 13 milliseconds. That's the cool thing about us humans, we all see the world a little bit differently and one way of assessing how our brains work is to spot hidden objects in optical illusions. On that note, why on take on today's challenge and see where you stand?
How do optical illusions work?
We humans have a long relationship with optical illusions?spanning centuries. In fact, it goes as far back as ancient Greece. Did you know the ancient used optical illusions on temple rooftops to create the effect of curved surfaces? But this visual trickery goes further back.
It was in 5 B.C. when Greek philosopher Epicharmus put forward the theory that our senses, not our brains, are responsible for misinterpreting optical illusions.?However, Protagoras, another Greek philosopher, argued that the environment played a significant role in how our physical senses picked up information.?Plato, on the other hand, claimed that our minds and our eyes work together to interpret external stimuli, something that is broadly believed to this day.
MIT researchers have found that it takes just 13 milliseconds?for our brains to process images. "That's why optical illusions can trick us so easily," explain the experts at CBD.co. "Our brains are making split-second decisions about what we're seeing."?
