In order to study the relationship between body temperature and reaction time (RT), and check the hypothesis proposed by Kleitman (Sleep and Wakefulness, University Press, Chicago, 1963) about a 'Basic Rest-Activity Cycle' (BRAC), RT tasks were delivered to 24 subjects at 10-min intervals for 320 min, while simultaneously registering bilateral ear canal temperatures. Time series analyses in frequency and time domains were applied to the data. Our results did not show a 90-100 min ultradian rhythmicity in the performance of RT tasks, but 6 of the 24 subjects presented significant periods within limits of BRAC in temperature.
为了研究体温与反应时间（RT）之间的关系，并检验克莱特曼（《睡眠与清醒》，芝加哥大学出版社，1963年）提出的关于“基本休息-活动周期”（BRAC）的假设，以10分钟的间隔向24名受试者进行反应时间任务测试，持续320分钟，同时记录双侧耳道温度。对数据进行了频域和时域的时间序列分析。我们的结果并未显示反应时间任务表现中存在90 - 100分钟的超日节律，但24名受试者中有6人在BRAC温度范围内呈现出显著周期。
