Quiz: When Did You See It?

When Did You See It?

In the words of the renowned neuroscientist Dr. Beau Lotto, “The brain didn't actually evolve to see the world the way it is ... The brain has evolved to see the world it is useful to see."

And how does the brain adapt to seeing in a useful way? Without delving too deep into vision science theories, such as Baysian models, a simple truth that defines how we see is the fact that our brain constantly defines and re-calibrates the “norm” in every visual situation.

So when a visual situation deviates from what our brain knows as the “norm,” optical illusions are a result of our brains' responses to abnormal visual experiences. In other words, our brains will “act out” and arrive at seemingly “inappropriate” interpretations.

How quick is your optical perception? Can you find the hidden image?
