ABSTRACT:

Introduction: Handedness is perhaps the most overt reflection of lateralization of the central nervous system in humans. Humans show a strong and population-level bias toward using one hand rather than the other for manual activities, which is unusual among mammals. As handedness is biologically and genetically linked, so it 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 anything is created by using symbols and our intelligence can be communicated to others by reading, speaking and writing. Researchers argue that right handers are more intelligent than the left handers and this is the reason behind changing the handedness of the children. This present study aims at finding the authencity of this opinion.

Aim: We assessed the cerebral dominance and association between handedness and intelligence among school students.

Method: Lateral preference inventory for handedness and Raven’s Standard Progressive Matrix Test for intelligence.

Statistical method used: IBM statistics-20. The P-Values less than or equal to 0.05 (P≤0.05) were considered as statistically significant.

Result: Statistical significance results were observed between left and right handers in terms of gender, age and educational standards.

Conclusion: Left handed students were more intelligent than right handed students. Furthermore if more accessories are specially designed for left handers, they can achieve much more better.

Key words: Left handers, right handers, cerebral dominance, intelligence, language.
