Confuse your Cognition by a sexy spinning girl

Spinning sexy girl

Here is a method to confuse your brain. Your cognition is going to be confused. Don't worry. It is a temporary effect.

Take a look at the spinning girl. Can you see it spinning clockwise or counterclockwise? I see it spinning clockwise, but I was able to change it in the other direction, its hard for many people. Give it a chance.

The spinning girl is a form of the more general spinning silhouette illusion. The image is not objectively "spinning" in one direction or the other. It is a two-dimensional image that is simply shifting back and forth. But our brains did not evolve to interpret two-dimensional representations of the world, but the actual three-dimensional world. So our visual processing assumes we are looking at a 3-D image and is uses clues to interpret it as such. Or, without adequate clues it may just arbitrarily decide a best fit - spinning clockwise or counterclockwise. And once this fit is chosen, the illusion is complete - we see a 3-D spinning image.

By looking around the picture, focusing on the shadow or a second part, you can force your visual system to reconstruct the image and can choose the opposite direction and suddenly the image will spin in the opposite direction.
