To compare auditory and visual reaction time in mobile users and non user.
Cross sectional observational study.
Thirty subjects (Male:Female 19:11) using mobile and 30 (Male:Female 13:17) subjects who were not using mobile were recruited for the study. The reaction time was recorded for auditory (4 different frequency) stimuli and visual (blue, red, green and yellow) stimuli. As soon as the stimuli was perceived by the subject, he responded by pressing the response switch by the index finger of the dominant hand. The display indicated the response time.
In the present study all visual and most of the auditory stimulus had evoked significantly prolonged reaction time in chronic mobile users when compared to the control group. The reaction time with respect to visual stimulus of red, blue, green and yellow was found to be prolonged in chronic mobile users. Also the reaction time to auditory stimulus of 3 different types of sounds was found to be significantly increased.
The reaction time with respect to the red, blue, green and yellow visual stimulus is found to be prolonged in chronic mobile users. This points out to the fact that such subjects could more vulnerable for accidents as traffic signals also have the same colour lights. Also the reaction time to the auditory stimulus of different horn sounds were shown to be prolonged in chronic mobile users. This points out to the fact that chronic mobile users are more prone to traffic accidents.
