Abstract

Background and Aim: Perceptual abilities like visual reaction time are indicative of cognitive and motor performance in many daily activities. Simple reaction time is a type of reaction time that covers a large part of daily life. The purpose of the present study was to compare simple visual reaction time to red light and green light stimuli.
Materials and Methods: Simple visual reaction time of 63 female volunteers to red and green light stimuli were measured by speed anticipation reaction test software. Paired T-test was used for analyzing data.
Results: The results showed that there was no statistically significant difference between simple visual reaction time of red light stimulus and green light stimulus (P=0.094, t=1.699).
Discussion: The present study showed that participants respond similarly to red light and green light stimuli.
