Does Left Brain or Right Brain Dominance Determine How We Learn?

Throughout the ages, people have been curious why we all think and learn differently. One theory that has come about is that of left brain or right brain dominance. It is thought that the different hemispheres of the brain serve different functions and if one hemisphere is dominant over the other in an individual; the individuals thinking and learning is stronger in the areas that hemisphere controls. Although this theory has been in use for many years, scientists are still testing the theory. Educators are also using this theory to learn how to teach students that have different learning styles and learning disabilities. This information has been compiled to inform and allow individuals to make their own assertion of whether or not left brain or right brain dominance determines how we learn. The theory of left brain or right brain dominance was introduced by Roger Sperry in the 1960’s (Salem, 1994). Sperry began researching the corpus callsum, the connecting tissue for the hemispheres of the brain, to discover its function (Salem, 1994). He experimented on a cat with a severed corpus callsum to see what affects it may have on the cat’s memory (Salem, 1994). Sperry found that if he taught the cat a simple task, while only the cats left eye was open, the cat couldn’t complete the task when only it’s right eye was open (Salem, 1994). This would prove that if the brain is no longer connected by the corpus callsum, then information is no longer transferred from on hemisphere to the other, and therefore the two halves could work independently (Salem, 1994). Experiments were later performed on humans in whom the corpus callsum was previously severed to control seizures (Salem, 1994). The experiment was conducted i... ... middle of paper ... ...erry, K.
