The purpose of the study was to determine the effect of visual and auditory warning on visual reaction time with variations of subjects' alertness. An experimental group of 30 subjects was tested with an auditory or visual warning signal; foreperiods lasted 3, 2, and 4 sec. Reaction time was shorter as alertness improved and with an auditory warning signal. Comparable measures in a control group showed that visual reaction time was shorter when an auditory warning signal was used.
该研究的目的是确定视觉和听觉警告对视觉反应时间的影响，以及受试者警觉性的变化情况。一个由30名受试者组成的实验组接受了听觉或视觉警告信号测试；预备期分别为3秒、2秒和4秒。随着警觉性的提高以及使用听觉警告信号，反应时间会缩短。对照组的类似测量结果表明，当使用听觉警告信号时，视觉反应时间会更短。
