Research is presented to suggest that similar to other parts of the body, the brain has two sides [hemispheres)] (Pinel, 2006). Although the left and right brain are similar in appearance, the two hemispheres are different, and have a different functions or lateralization. Thus, the brain is made up of two structures, the left and right cerebral hemispheres (p.396). Specifically, the left hemisphere plays a special role in both language and voluntary movements. According to Pinel, the left hemisphere controls all complex behavioral and cognitive processes. As he further explains, persons with Aphasia may have a left hemisphere lesion that causes them to have difficulty performing movements when asked to perform them. However, they have no difficulty performing the same movement when thinking about it.

Sternberg (2006) points to the works of Paul Broca (1836), a French philosopher and later Wernicke for the discussion on brain lateralization. Following the identification of speech (Broca's area) as function of the left brain hemisphere, Wernicke studied deficits in language among patients and traced those deficits to the left area of the brain. Thus it is accepted that language ability is largely located in the left hemisphere of the brain. In their study, Valaki, Maestu, Simos, Zhang, Fernandez, Amos et al. (2004) examined the differences between Chinese and Indo-European use of language from both written and spoken perspectives.They examined patterns of neurophysiological activity in temporal and temporoparietal areas as speakers of two ...
