Neuropsychologist Dr. Roger Sperry developed the theory of brain lateralization — what we think of as the right brain/left brain theory — in the mid-1900s, winning the Nobel Prize for his work in 1981. While modern scientists now know far more about the brain, making Sperry's theories a bit outmoded, it's still fun to gain a deeper understanding of the way your brain works.

So are you left-brained, with logic and order defining the way you approach the world? Or are you right-brained, with an artistic, spatial take on life? While everyone is a balance of both, this quiz can help you understand which side is dominant in your own personality.

Fun Facts

If you're right-handed, there's a 95 percent chance that the left side of your brain controls your language use. However, if you're left-handed, that chance drops to about 65 percent.

While both halves of your brain work together in harmony to keep your mind and body functioning, your right brain handles visual images, spatial ability and music. The left brain devotes itself to language, logic and math.
