I tried. I still can only see her spinning one direction. It's so freaky that you guys can see her spinning in another direction.

I am 34% left and 66% right and I am right handed.

Yes, it's a bit freaky when you realize it can spin back an forth in different directions.  Take a break and try again later, try to think that it's spinning the other directions and only use your non dimate eye.  Sometimes it helps to adjust the angle, like you are looking up at it, then slowly bring more afront.

There are other ones like that too:

What do you see?  And old woman or a young lady?

53/47

"It has been established that the silhouette is more often seen rotating clockwise than anti-clockwise. According to an online survey of over 1600 participants, approximately two thirds of observers initially perceived the silhouette to be rotating clockwise. In addition, observers who initially perceived a clockwise rotation had more difficulty experiencing the alternative."

From Wikipedia. I guess I'm one of the people who can't experience the alternative. 

I can usually see both possible aspects of pictures, but the Spinning Dancer is different. I can't see her spinning the other way.

Equally 56% left 44% right :)

How are so many people scoring 53%-47%'s???? This test doesn't seem very indepth and probably isn't accurate at all.

Another fun question from the brain games series:


Which way is the bus going?

Young children guess this right all the time with no difficulty, think about there the doors are.

If you focus on her front foot it tends to be easier to 'change' her direction of spin.  If I look at more than a few seconds i can actually see her oscillating back and forth through 180 degrees and not spinning at all.

If you can't make her 'change' try looking at it a couple of hours later and see if it has change.  Our brains go through a normal cyclical oscillation of hemispheric dominance throughout the day (as distinct from 'background' hemisphere dominance), so seeing her spinning to the right indicates you are presently right dominant.  Try 1-2 hours later and you may find that you see her spinning the other way.

That's probably because there is no such thing as a dominant brainside. Recent studies have already proven it is a myth.
