ABSTRACT
Effect of stress (cold) on visual reaction time (VRT) and auditory reaction time (ART) was studied in 100 healthy subjects (17-25 yrs) by computer based software. During the standard cold pressor test (CPT), there was significant increase (p< 0.001) in VRT. There was significant increase (p< 0.001) in ART. There was increase in blood pressure and heart rate. This increase in VRT and ART with CPT was probably due to decreased conduction velocity of nerves, which could be due to vasoconstriction attributed to increased sympathetic activity caused by cold.
Key words: CPT, ART, VRT
