There are circadian (approximately 24 h) rhythms for a wide range of human physiological and psychological functions including mood and performance efficiency. These rhythms are self-sustaining in conditions of temporal isolation, indicating that internal oscillators (or biological clocks) control them. Recent research has proposed an endogenous two-oscillator model of the human circadian system, with one oscillator indicated by the core body temperature rhythm and a second oscillator responsible for the daily cycle of sleep and wakefulness. The present study was designed to produce a desynchronization in period between the two oscillators, to assess directly the behaviour of the rhythms of different performance tasks. The results, reported here, indicate that a simple manual dexterity task is almost entirely under the control of the temperature rhythm oscillator, whereas a more complex cognitive task demonstrates a periodicity which appears to be influenced by those oscillators controlling temperature and the sleep/wake cycle.
包括情绪和工作效率在内，人类广泛的生理和心理功能都存在昼夜节律（约24小时）。这些节律在时间隔离的条件下是自我维持的，这表明内部振荡器（或生物钟）对其进行控制。最近的研究提出了一种人类昼夜节律系统的内源性双振荡器模型，其中一个振荡器由核心体温节律表示，另一个振荡器负责睡眠和觉醒的日常周期。本研究旨在使两个振荡器之间的周期产生不同步，以直接评估不同表现任务节律的行为。此处报告的结果表明，一项简单的手部灵巧性任务几乎完全受温度节律振荡器的控制，而一项更复杂的认知任务则表现出一种周期性，这种周期性似乎受那些控制温度和睡眠/觉醒周期的振荡器影响。
