This image shows a girl that is spinning. Depending on your preference of using the Left or the Right side of the Brain, she will either spin Counter-Clockwise or Clockwise. Now try, while watching the girl spin, to change the direction of the spin - this means that you are able to change from one side of your brain to the other! According to a 5 year study at Yale University USA, you then belong to 14% of the population that is able to do that. However this ability can be trained, like anything. To change direction from Counter-Clockwise to Clockwise try thinking a creative thought. To do the opposite, making a calculation could do the trick!
