To quantify the effects of sleep periods that have different lengths of time during continuous operations (CONOPS) 2 independent groups of subjects performed several cognitive tasks for 3 days. The 72 h trial period contained three 60-min sleep periods for the 10 subjects of the experimental group and three sleep periods of 4 h each for the 14 subjects of the control group. With the exception of only one subtest the statistical analyses of the test results of the 2 groups show no significant differences in cognitive performance. It is suggested that high motivation is responsible for comparable performance of the subjects, which was essentially obtained by a monetary pay system for successful test performance.
为了量化在连续作业期间不同时长睡眠时段的影响，两组独立的受试者连续3天执行了多项认知任务。72小时的试验期内，实验组的10名受试者有三个60分钟的睡眠时段，对照组的14名受试者有三个各4小时的睡眠时段。除了一项子测试外，两组测试结果的统计分析表明，认知表现没有显著差异。研究表明，受试者表现相当是由于积极性高，而这主要是通过对成功完成测试给予金钱奖励的制度实现的。
