👀Look at these optical Illusions! 👀

Hi @carodilo thanks for reminding me that it was Gestalt's theory! I kept thinking "the whole" but his name escaped my mind. What do you teach and what grade?

Check out the spiral…except it is not a spiral, just circles.

Don’t believe me? Use your finger to follow the fake spiral.

The tilt of the boxes fools your brain into believing it is a spiral.

Ok here I go with my googling again! Do you want to know the different types of optical illusions? Sure you do! Ok read below.

Literal Optical Illusions

A literal illusion is when the image you see is different from the images that make it up. For example, the illustration Hill created which is actually two images strategically drawn to look like one fluid image is a literal illusion. Think of it as a reversible figure. The end result you see in a literal illusion is based on your perception. Both images exist. 

Physiological Optical Illusions

These types of optical illusions are more complex because they reply on the over stimulation of the brain’s senses. The eye “sees” so much light, movement, color, dimension and size that it confuses the brain. The mind benders you see like geometric illusions and impossible pictures are physiological optical illusions. At first glance, a two-dimensional figure looks like it’s three-dimensional. That’s because the brain immediately interprets it to be that way. Upon further investigation, the brain realizes what the eye is actually seeing. The image in question does not exist in nature. 

Cognitive Optical Illusions

This type of illusion is the most researched by scientists and psychologists because it is the most complex type of trick the eye can play on the brain. Unlike other optical illusions, these illusions rely on what the subconscious mind thinks and how it relates one object to another. In other words, what you see is believed to give insight into the depths of your thinking. A cognitive optical illusion uncovers what your brain infers and understands about something that has not been explained.

I like the Literal Optical Illusions the best. The middle one doesn't work well for me with my vision. Well the Cognitive Optical Illusions seems very similar to the first because it could be two things in one image. Now I'll go look to see if I can find more of the cognitive one.
