Influence of colour difference on visual reaction times in Young Adults

Dr Shweta Sehgal, Dr Rahul Kapoor

Abstract :

Reaction time is defined as an interval of time between the application of stimulus and the initiation of appropriate voluntary response as the subject has been instructed to respond as rapidly as possible. Simple reaction time is used to evaluate the processing speed and the co–ordination between the sensory and motor systems. Reaction time is influenced by various factors. Therefore, the effect of colour stimulus in modulating the reaction time among young Indian males has been investigated in this study. A total of 60 healthy volunteers (young males) of age group 19–27 years were included in the study. The subjects were presented with two visual stimuli viz.; red and green light by using an audio visual reaction time apparatus. Using paired t–test for comparison of visual reaction time between red and green colour in young males, it was observed that the response latency for red colour was significantly less compared to green colour (P < 0.05). From the present study, it could be suggested that the colour stimulus has an impact in modulating the visual reaction time.
