在“精神”任务的效率进行观察时，根据以下两个不同的4小时轮班制度之一，连续12天的时间表。28名受试者被分配到“旋转”系统，即24小时中的每4小时每72小时重复工作一次，或者被分配到“稳定”系统，即每天的工作时间为1230至1630和2400至0400。在旋转系统中，在一天中不同时间的几个方面的表现水平的变化被发现与自然昼夜节律引起的体温同时波动密切相关。这种节律的相位的转变，以响应现在的睡眠/清醒周期所施加的稳定的系统，伴随着相应的变化，在两个工作期间观察到的相对水平的性能。因此，在这两个系统中，体温实际上是表现效率的预测因子。本文还讨论了轮班工作组织的一些含义
Efficiency at ‘ mental ’ tasks was observed when performed according to a time schedule imposed by following one of two different 4-hour shift systems for a period of 12 consecutive days. Twenty-eight subjects were assigned either to a ‘ rotating ’ system, in which each 4-hour period of the 24 hours was worked once every 72 hours in a repeating cycle, or to a ‘ stabilized ’ system, in which the work periods were from 1230 to 1630 and 2400-0400 each day. In the rotating system, alterations in the level of several aspects of performance at different times of day were found to be related quite closely to concurrent fluctuations in body temperature arising from its natural circadian rhythm. A shift in the phase of this rhythm in response to the now sleep/waking cycle imposed by the stabilized system was accompanied by a corresponding change in the relative levels of performance observed in the two work periods. Thus in both systems body temperature was, in effect, a predictor of performance efficiency. Some implications for the organization of shift working are discussed
