A COMPARATIVE ANALYSIS OF SIMPLE VISUAL REACTION TIME BETWEEN CONGENITAL DEAF AND NORMAL CHILDREN

Background & objectives: Cross modal plasticity research studies shows that unused brain neurons in case of loss of sensory organ can be utilize for other sensory modalities, thus enhancing ability of disable individual to perform day today tasks as equal or in some cases even better than normal individual. Present study gives insight on the same principle of “Cross modal plasticity”. Methods: Total 223 cases were included in present study. Out of 223 cases, 100 deaf children and 123 normal children were included in our study. Study was conducted at various schools in Jamnagar city and prior permission from IEC and respective school principals was taken. Information sheet was provided about present study and only when voluntary consent given by school teachers, students were included in study. Simple Visual Reaction Time (VRT) was done using DirectRT© software in laptop. Data analysis was done using Excel 2016 data analysis tool pack. P
