'Drawing on the Right Side of the Brain' does some investigation into this stuff. Though I think the science is 20 or 30 years old by now, theres evidence that the left hand's motor functions are controlled by the right side of the brain, which is the more creative side and the left side/right hand is the more logical. The science behind it is probably investigated a lot further now.
