The findings of a laboratory investigation of the relationship between the subjective and physiological components of work underload are reported. The subjective component is described in terms of the subjective work underload checklist, mental effort, and cognitive arousal. The physiological component is defined in terms of heart rate and heart rate variability. Evidence for an increase in work underload with a decrease in heart rate is provided. The relevance of this research to the aerospace environment is discussed and the need to investigate the behavioural component of work underload emphasized.
报告了一项关于工作负荷不足的主观因素与生理因素之间关系的实验室调查结果。主观因素通过主观工作负荷不足清单、心理努力和认知唤醒进行描述。生理因素根据心率和心率变异性进行定义。提供了心率下降时工作负荷不足增加的证据。讨论了该研究与航空航天环境的相关性，并强调了研究工作负荷不足行为因素的必要性。
