Left Brain v Right Brain

[Minister Masket]

There's an easy way to do this:
Right handed people have a left-side dominant brain.
Left handers have a right-side dominant brain.

I am right handed, but saw the girl going clockwise. The animation LIES!

Does anyone here use Microsoft Excel regularly? There's a similar phenomenon when you use the copy function on a cell, or group of cells. The cells become highlighted with a broken line, and this broken line can be perceived to be moving either clockwise, or anti-clockwise. And if you're at work and really bored, you can get the broken line to constantly switch directions, so that it never "moves".

Boobies! Who cares if they're in silhouette?

Counter clockwise at first but once I concentrated it went clockwise, but when I glance it goes counter clockwise.

CW. I have been staring at it for 12 minutes now. I'll give it another half hour.

EDIT: using peripheral vision it is possible to make her do karate

[s.xkitten]

both ways from the start...she would start out one way, then the other, then back, then the other...

I started of seeing Clockwise, but can now manage to change it at will.

It doesn't change back and forth on it's own as I was watching her go one way while someone else was watching her go another way at the same time.

look carefully and you'll notice she even changes the leg she stands on. it's at trick! these are mirror images of the same doll changing randomly.

It's not a trick man. I thought it might be at first as well, since the comments below the video had people saying the video just switched. But after some concentration I can make the rotation switch at will, and I know its not just coincidence with the video coinciding with my efforts.

As another poster said, I can also make her complete 1 half the rotation, then turn around, and repeat. Always doing 180 degrees back and forth and never spinning fully around.

If you think this is just a video trick and not a mind trick, keep staring at it. Eventually you will be able to control it yourself, and then you will feel dumb that it seemed so certain she was spinning in just one direction. I know I did.

Both directions, using the outstretched foot to switch.

'Course, this dancer is much more impressive than a broken line.

I know exactly what you mean, but I think I have a simpler example.

If you started reading that pattern, you would say to yourself "one, two, one, two..." and so on. You mind is can convince itself that the two follows the one. If you begin saying two, one, two, one... it sounds very different, but its clearly the same pattern.

This illusion is the same deal. It's just an image oscillating back and forth, not actually rotating. But it appears to be rotating, and how your brain perceives it at first glance determines the rotation. Thats why it feels you get stuck on a certain direction. If you are able to trick your mind into switching the directions once, it becomes much easier.

EDIT: Try the 1-2-1-2 trick. If you say it to yourself repeatedly you can switch back and forth between it sounding like 1-2 or 2-1. Don't change the emphasis, just think about the loop starting in a different place. If you can do that, the rotating image works exactly the same way.

clockwise, I'm creative, because a machine told me I am


and I'm too lazy to train myself...
