反应时间(RT)是对刺激反应的量度。RT在我们的生活中扮演着非常重要的角色，因为它的实际影响可能会产生巨大的后果。可能影响人类平均RT的因素包括年龄、性别、左手或右手、中央视力与外围视力、练习、疲劳、禁食、呼吸周期、个性类型、运动和受试者的智力。本研究的目的是在医学一年级学生的性别和体力活动水平的基础上比较视觉RTS(VRT)和听觉RTS(ARTS)。本文对120名18~20岁健康医学生进行了横断面研究。使用笔记本电脑中的Inquisite4.0(计算机软件)确定靶刺激的RT，即用于测量ART的嘟嘟声，以及用于测量VRT的红色圆圈。任务是在刺激方案一推出就按下空格键。获取每个刺激的五个读数，并记录每个刺激各自的最快RT。并进行统计分析。与视觉刺激相比，两性对听觉刺激的反应时显著减少(P<；0.001)。男、女医学生RT差异有统计学意义(P<；0.001)，健康医科一年级学生久坐与经常锻炼的RT差异有统计学意义。在医学生中，ART比VRT更快。此外，与女医学生相比，男医学生在听觉和视觉刺激上都有更快的反应时效度。与久坐不动的医学生相比，经常锻炼的医学生有更快的RTS。
Reaction time (RT) is a measure of the response to a stimulus. RT plays a very important role in our lives as its practical implications may be of great consequences. 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 RTs (VRTs) and auditory RTs (ARTs) on the basis of gender and physical activity levels of medical 1st year students. The present cross-sectional study was conducted on 120 healthy medical students in age group of 18–20 years. RT for target stimulus that is, for the beep tone for measuring ART, and red circle for measuring VRT was determined using Inquisit 4.0 (Computer Software) in the laptop. The task was to press the spacebar as soon as the stimulus is presented. Five readings of each stimulus were taken, and their respective fastest RT's for each stimuli were recorded. Statistical analysis was done. In both the sexes’ RT to the auditory stimulus was significantly less (P < 0.001) as compared to the visual stimulus. Significant difference was found between RT of male and female medical students (P < 0.001) as well as between sedentary and regularly exercising healthy medical 1st year students. The ART is faster than the VRT in medical students. Furthermore, male medical students have faster RTs as compared to female medical students for both auditory as well as visual stimuli. Regularly exercising medical students have faster RTs when compared with medical students with sedentary lifestyles.
