IMPACT OF HEMISPHERIC DOMINANCE ON BEHAVIOURAL LATERALITY STYLE
The cerebral hemispheres play crucial role in forming the mental state of human being. “Hemisity”, is an aspect of the brain that considers two distinguished modes of information flow into the brain their differential processing modes within the two hemispheres. These two modes of information processing become the foundation for the development of differences in the functions of the two cerebral hemispheres. Each hemisphere has certain areas assigned with certain functions. The dominance of a particular processing mode in the brain of an individual gives rise to specific behavioural and personality characteristics. An individual may be excellent in performing certain tasks and may exhibit characteristics which would define his individuality, his identity and the dominant talent. These characteristics may be strongly correlated with the hemispheric dominance. Thus, it is considered that there may be a close link between hemisity and behavioural characteristics of an individual. This research aims at understanding the correlation between Hemisity and behavioural characteristics of a group of volunteers. The samples selected for this research were 150 males and 150 females of age group, 18-25 years. To measure characteristics exhibited by an individual Binary Preference Questionnaire (Morton, 2003) will be used and a questionnaire is developed and validated by an expert neuropsychologist to measure the brain dominance and characteristics exhibited by the right or left-brain oriented individuals. The results showed that less than half of the total number of samples reflected hemispheric dominance and exhibited respective hemisphere characteristics. However, more than half of the samples reflected hemispheric dominance but exhibited characteristics of nondominant hemisphere. The hypothesis that there exists a relation between Hemisity and behavioural characteristics exhibited by the right and left-brain oriented individuals is not completely supported by the data obtained. Thus, the result stands inconsistent with the data obtained and the earlier researches.
