对18名在多次睡眠潜伏期测试中睡眠时间异常短（平均潜伏期小于或等于6分钟）和20名睡眠时间异常长（平均潜伏期大于或等于16分钟）的健康、无症状、正常年轻男性的夜间睡眠、表现和个性进行了比较。在夜间睡眠记录中，与警觉的受试者相比，困倦的受试者的睡眠潜伏期更短，醒来时间更少，总体睡眠效率更高。白天，困倦的受试者比警觉的受试者在分散注意力和警惕性任务上表现更差。在明尼苏达多相人格量表和詹金斯活动人格测量中，困倦和警觉的受试者没有明显差异。在人格与能力测验焦虑量表上，困倦的被试比警觉的被试表现出更高的焦虑水平。这些数据被解释为表明困倦的受试者由于长期睡眠限制而有睡眠债务。
The nocturnal sleep, performance, and personality of healthy, asymptomatic, normal young men, 18 who had unusually short sleep latencies on the Multiple Sleep Latency Test (average latency, less than or equal to 6 min) and 20 with unusually long latencies (average latency, greater than or equal to 16 min) were compared. On the nocturnal sleep recording, sleepy subjects had a shorter sleep latency, less waking time, and overall greater sleep efficiency than alert subjects. During the day, sleepy subjects performed more poorly than alert subjects on divided attention and vigilance performance tasks. The sleepy and alert subjects did not differ appreciably on the Minnesota Multiphasic Personality Inventory and Jenkins Activity measures of personality. On the Institute of Personality and Ability Testing Anxiety Scale, the sleepy subjects showed higher levels of anxiety than the alert subjects. The data were interpreted as indicating that the sleepy subjects had a sleep debt due to chronic sleep restriction.
