breaking bad

Right and left brain

They are now presenting that spinning dancer image as a right/left brain dominance test. I am dubious.

"If clockwise, then you use more of the right side of the brain and vice versa. Most of us would see the dancer turning anti-clockwise though you can try to focus and change the direction; see if you can do it."

Here's another left/right brain test, and here's another. I get mildly right-brain FWIW.

When I was younger it was commonplace that the whole right/left brain stuff was theoretically dubious, and the experimental evidence (such as the people with a severed corpus callosum) seemed to be discounted by the academics. The theory seems to get more credence now. I don't know if that's because more compelling evidence has been made available, or because psychology has become a lot less hidebound.
