The cerebral hemispheres play crucial role in forming the mental state of human being. “Hemisity”, is an aspect ofthe brain that considers two distinguished modes of information flow into the brain their differential processingmodes within the two hemispheres. These two modes of information processing become the foundation for thedevelopment of differences in the functions of the two cerebral hemispheres. Each hemisphere has certain areasassigned with certain functions. The dominance of a particular processing mode in the brain of an individual givesrise to specific behavioural and personality characteristics. An individual may be excellent in performing certaintasks 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 theremay be a close link between hemisity and behavioural characteristics of an individual. This research aims atunderstanding the correlation between Hemisity and behavioural characteristics of a group of volunteers. Thesamples selected for this research were 150 males and 150 females of age group, 18-25 years. To measurecharacteristics exhibited by an individual Binary Preference Questionnaire (Morton, 2003) will be used and aquestionnaire is developed and validated by an expert neuropsychologist to measure the brain dominance andcharacteristics exhibited by the right or left-brain oriented individuals. The results showed that less than half ofthe 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 behaviouralcharacteristics exhibited by the right and left-brain oriented individuals is not completely supported by the dataobtained. Thus, the result stands inconsistent with the data obtained and the earlier researches.
