Rotating Snakes Illusion

Rotating Snake Illusion
Now let’s look at the last illusion under the topic of visual illusion studies that of rotating snakes. You have to be warned. It might be a bit dizzying to look at. So what do you notice? Can you see the snakes moving? The pattern is actually static but appears to be in motion. It seems as if there are several snakes moving in a circular direction. To better unpack the reason behind this illusion, scientists created a black and white version and a control stimulus, which is basically identical in the overall configuration, but with no perception of motion. Why can’t we perceive the illusion in the control pattern?
Well, if you take a look at the pattern of the local input or the sequence of brightness of the blobs, it’s been changed, disrupting the illusion. Indeed, the illusion works only of the blobs are arranged
with this sequence: black, dark gray, white, followed by light gray. Now it’s your turn! In the next step, you will do your own experimenting by setting up a free choice test, which you can easily do with your pets. Good luck!

Now let’s conclude this video series with a famous motion illusion, rotating snakes!

Try not to get too dizzy with this illusion.

After watching the three videos, is there still something unclear about the difference between free-choice tests and training procedures? If you still have questions or doubts, just ask them in the Comments section and we’ll try to iron them out.
