Effect of number of stimuli on auditory reaction time in healthy subjects of Bhavnagar region.

Background: Present study aimed to see effect of number of stimuli on auditory reaction time. Reaction is purposeful voluntary response to different stimuli as auditory stimuli. Auditory reaction time is time required to response to auditory stimuli. Materials and Methods: The auditory reaction time was measured by the reaction time instrument in subjects. Simple reaction time and choice reaction time measured. During the reaction time testing, auditory stimuli were given for three times and minimum reaction time was taken as the final reaction time for that sensory modality of that subject. The results were statistically analyzed and were recorded as mean ± standard deviation and Student's paired t-test was applied to check the level of significance. Results and Conclusion: The study shows that simple auditory reaction time is less than choice auditory reaction time. Mental processes are involved in identification of stimulus, response selection, and programming and this takes certain time. Response to stimuli would be faster if number of stimuli is lesser in number. In routine life, many works done on information of auditory stimuli. Person should be careful while driving in talking with others or in mobiles. Training reduces reaction time. In medical examination, there are identification of instruments, graphs, bones, and viva questions as well. Student can practice and decrease mental processing time for identification of all this and can respond quickly. [ABSTRACT FROM AUTHOR]
