Are there asymmetries in the functions of the two cerebral hemispheres? A great deal of evidence has accumulated in recent years suggesting that the left brain and the right brain are not identical in their capabilities. This study is designed to demonstrate that for right-handed people, who comprise over 90% of the population, the right hemisphere performs visual spatial tasks better than the left hemisphere. For most right-handers, whereas the left hemisphere excels in verbal and analytical tasks, the right hemisphere specializes in emotional, nonverbal, and visual-spatial tasks.
