A method of measuring fatigue is suggested in which alternative routes, requiring different amounts of effort, lead to different probabilities of success or failure. An experiment designed to investigate a task which has these features shows it sensitive to the fatigue generated by a synthetic work battery. Fatigued Ss shifted their choices towards easier, riskier routes, compared with their own earlier performance and with that of a control group; they also showed an increased error rate on a subsidiary measure. In a second experiment, measurements on the task were shown to correlate with self-rated fatigue.
提出了一种测量疲劳的方法，其中需要不同努力程度的替代路线会导致不同的成功或失败概率。一项旨在研究具有这些特征的任务的实验表明，它对合成工作负荷产生的疲劳很敏感。与他们自己早期的表现以及对照组相比，疲劳的受试者将他们的选择转向了更简单、风险更高的路线；他们在一项辅助测量中也表现出错误率增加。在第二个实验中，对该任务的测量结果显示与自我评定的疲劳相关。
