Reaction time (RT) is a measure of the response to a stimulus. Reaction time provides an indirect index of the processing ability of Central Nervous System and also a simple means of determining sensory-motor performance. It is the time interval between the onset of stimulus and the initiation of appropriate voluntary response under the condition that the subject has been instructed to respond as rapidly as possible and is a simple and non-invasive test for peripheral and central neural structures with a physiological significance. Factors that can affect the average human RT include age, sex, left or right hand, central versus peripheral vision, practice, fatigue, fasting, breathing cycle, personality types, exercise, and intelligence of the subject.
The aim was to compare visual Reaction time (VRTs) and auditory Reaction time (ARTs) on the basis of gender of nursing staff.
Materials and Methods: The present study was conducted in the SMS Medical College & attached hospitals, Jaipur. The study was done after getting approval from institutional human ethical committee. The study was conducted on 80 healthy normal nursing staff [males& females] of 20-35 years old. Reaction Time was recorded with the help of Audio-visual Reaction Time apparatus, supplied by Medi system, Yamuna Nagar. It had display accuracy of 100% and resolution 0.01 second. Statistical analysis was done.
Results: In both the sexes’ Reaction time to the auditory stimulus was significantly less (P < 0.001) as compared to the visual stimulus. Significant difference was found between Reaction time of male and female nursing staff(P < 0.001)
Conclusion: The effect of night shift duty stress on auditory reaction time in males and females shows that males have significantly better auditory reaction time than females. Similar results were found for Visual reaction time indicating that males can tolerate night shift duty stress better than females. Females are unable to adjust to shift duties due to the family problems, resulting into shift work intolerance and thus prolongation of audio-visual reaction time. The ART is faster than the VRT in nursing staff. Furthermore, male have faster RTs as compared to for both auditory as well as visual stimuli.
