Abstract
Introduction: Handedness is perhaps the most overt reflection of lateralization of the central nervous system inhumans. Humans show a strong and population-level bias toward using one hand rather than the other formanual activities, which is unusual among mammals. As handedness is biologically and genetically linked, soit has various effects on one’s behaviour and abilities. Since intelligence has an impact on human behaviour,intelligence is considered an important aspect. Language is a system by communication. The meaning of anythingis created by using symbols and our intelligence can be communicated to others by reading, speaking andwriting. Researchers argue that right handers are more intelligent than the left handers and this is the reasonbehind changing the handedness of the children. This present study aims at finding the authencity of thisopinion.Aim: We assessed the cerebral dominance and association between handedness and intelligence among schoolstudents.Method: Lateral preference inventory for handedness and Raven’s Standard Progressive Matrix Test forintelligence.Statistical method used: IBM statistics-20. The P-Values less than or equal to 0.05 (<0.05) were considered asstatistically significant.Result: Statistical significance results were observed between left and right handers in terms of gender, age andeducational standards.Conclusion: Left handed students were more intelligent than right handed students. Furthermore if more accessoriesare specially designed for left handers, they can achieve much more better.
