If you see this lady turning in clockwise you are using your right brain.
If you see it the other way, you are using left brain.
Some people see both ways, and if you can,
that means you are switching between right and left.

Try to switch directions; it can be done. 
If she is going to the right, try doing some math in your mind. 
If she is going to the left, create something mentally
(for example, put pink polka dots on a lemon). 

If you are right-brained dominant, you could be a great hypnotic subject!
