Roger Sperry was a neuropsychologist known for his split-brain research who won the 1981 Nobel Prize in Medicine. Through his split-brain research, he discovered that the right hemisphere of the brain is best at expressive and creative tasks like recognizing faces and expressing emotions, while the left hemisphere excels at logical, linguistic, and analytical thinking tasks like language and reasoning. Sperry argued that society discriminates against the right hemisphere and its nonverbal intellect.
