The Right Brain vs Left Brain, an article in the Daily Telegraph, carries a picture of a dancer who is spinning (click on the picture below to see it spinning). The question is, do you see the dancer going clockwise or counter-clockwise?
Apparently, those whose right side of the brain dominates will see it going clockwise, and those whose left side of the brain dominates will see it going counter-clockwise. There are also some who can focus and change the direction! The article reports that "most of us would see the dancer turning anti-clockwise".
However, I most certainly see it going clockwise, and try as I might, I cannot make it go counter-clockwise!! A quick search on the internet indicated that many people saw the dancer going clockwise... then, I went to Daily Kos, and found that almost 70% of the votes were for "right brained". So much for "most of us" seeing the dancer turning anti-clockwise.
Still, it was rather surprising since I never thought of myself as "right brained"! Oh well, maybe I am after all! So, I poked around the huge WWW and found some info on brain functions:
