Abstract The reaction times of participants were tested according to 3 and 6 letter strings presented on a computer to the left and right visual fields of each participant. The participants would then press the ‘m’ key on the keyboard if the letter string was a real English word and the ‘v’ key if it was not. As the class expected, the results came out that the left hemisphere processed these letter strings quicker than the right hemisphere by an average of 150 ms for the three letter strings and 230 ms for the six letter strings. This went on further to prove that the left hemisphere clearly dominates the process of language in the brain as scientists have assumed for a while now. So once again, with these results we can establish that the two hemispheres of the brain control different aspects of the mind, and particularly from this experiment, language comes from the left. Introduction Psychologists have studied processes that take place in the mind for centuries now, and continue on to advance their knowledge. One of these processes that researchers focused on was that of hemispheric specialization, concerning the different functions of the two hemispheres of the brain. Scientists came to the conclusion that each hemisphere of the brain has one main function, but incorporates little pieces of the other as well. It is believed in the brain that the left hemisphere controls the actions of the right side of the body, and the right hemisphere controls the actions of the left side of the body. Similarly, vision works the same way, as we process objects in our right visual field with our left hemisphere and objects in our left visual field with our right hemisphere. Scientists also have concluded that the left hemisphere of the brain is “language” dominant, while the right hemisphere controls our “spatial tasks”. In knowing this, the experiment done by the class involved viewing objects presented to their two visual fields and having to determine whether the string of letters was a real word or not.
