Repeated measurements of reaction times were made individually in 53 healthy subjects at 60-sec intervals and continued for 30 min. The subject's visual perceptual task each minute was to determine the momentary cessation of the second hand of a clock and his reaction times were automatically recorded. The results showed that the subject's reaction times followed a free-running cycle ranging in frequency between 4 and 15 min when their reaction times were submitted to spectral analysis and autocorrelograms obtained. Error scores during the procedure showed significant correlations with chronological age but not with gender. The biological implications of these oscillations are discussed.
对53名健康受试者分别每隔60秒进行一次反应时间的重复测量，并持续30分钟。受试者每分钟的视觉感知任务是确定时钟秒针的瞬间停止，其反应时间会自动记录下来。结果表明，当对受试者的反应时间进行频谱分析和自相关图分析时，其反应时间遵循一个自由运行周期，频率在4至15分钟之间。该过程中的误差分数与实际年龄存在显著相关性，但与性别无关。文中讨论了这些振荡的生物学意义。
