In order to document circadian rhythmicity in various psychological functions under the chronobiologically 'pure' condition of temporal isolation, a battery of mood and performance tests were administered about 6 times per day to a heterogeneous group of 18 subjects (ages 19-81, 5 female). Each subject spent about 5 days in temporal isolation, entrained to a routine equivalent to his/her own habitual sleep/wake cycle. Average time of day functions were obtained for the mood and performance variables, and compared to rectal temperature data subjected to exactly the same statistical analysis. Significant time of day effects were found in the mood variables of alertness, sleepiness, weariness, effort required, happiness and well-being. Times of 'best' mood were different from the time of peak temperature. Moreover, the minima of sleepiness, weariness and effort occurred earlier in the day than the maximum of alertness. Significant time of day effects were also found in the speed with which search and dexterity tasks were completed. Only the dexterity tasks showed a complete parallelism with the temperature rhythm.
为了记录在时间隔离这种生物钟学上“纯粹”的条件下各种心理功能的昼夜节律，每天大约对18名异质受试者（年龄19 - 81岁，5名女性）进行一系列情绪和表现测试，约6次。每位受试者在时间隔离中度过约5天，遵循与他/她自己习惯的睡眠/觉醒周期相当的日常安排。获取了情绪和表现变量的日均功能时间，并与经过完全相同统计分析的直肠温度数据进行比较。在警觉性、困倦、疲劳、所需努力、快乐和幸福感等情绪变量中发现了显著的日均效应。“最佳”情绪时间与体温峰值时间不同。此外，困倦、疲劳和努力的最小值出现在一天中比警觉性最大值更早的时间。在完成搜索和灵巧任务的速度方面也发现了显著的日均效应。只有灵巧任务与温度节律呈现出完全的平行关系。
