Abstract

Background: Human reaction time denotes time taken by an individual to react to an external stimulus. The response obtained while measuring human reaction time is voluntary response obtained after training and is specific in nature. The purpose of this study was to find out whether the reaction time was faster for green light stimuli or red light stimuli. And to compare the visual human reaction times in males and females. Material & method: In this study we had studied the time taken between applications of visual stimulus and response obtained and comparison of the response in male and female volunteer. In this study visual reaction time (VRT) was studied in 125 male & 125 female Medical students in the age group of 17-20 years. Subjects were presented with two visual stimuli i.e. green light & red light stimuli. Paired and unpaired‘t’ test was used at appropriate places as a statistical test. The p value <0.05 was considered significant. Result: Human reaction times to green light stimuli were lesser than human reaction times to red light stimuli in males as well as in females. Conclusion: Green color evoked a faster response due to its stronger stimulation on the visual receptor than for red color in both male and female subjects.
