What is an optical illusion in psychology?
An optical illusion is characterized by visually perceived images that, at least in common sense terms, are deceptive or misleading. Therefore, the information gathered by the eye is processed by the brain to give, on the face of it, a percept that does not tally with a physical measurement of the stimulus source.
How do optical illusions trick your brain?
By arranging a series of patterns, images, and colors strategically, or playing with the way an object is lit, the brain can be tricked into seeing something that isn’t there. How you perceive proportion can also be altered depending on the known objects that are nearby. It’s not magic — it’s an optical illusion.
What is illusion and types of illusion in psychology?
