8名正常成年睡眠者在实验室中度过了4个非连续周。每周包括一个基线夜晚，然后是连续2个睡眠中断的夜晚，然后是2个恢复夜晚。破坏条件包括：a）每分钟累积睡眠后短暂觉醒，B）每10分钟累积睡眠后短暂觉醒，c）2.5小时正常睡眠，随后在每次睡眠开始时短暂觉醒，和d）完全睡眠剥夺。早晨的测试显示，所有的中断条件下最小的中断大约是在完全失去睡眠后看到的。在10分钟的条件下，性能下降较少，在2.5小时的睡眠条件下最少。在基线和总睡眠损失条件下的表现被用来预测在睡眠剥夺条件下使用四个睡眠阶段规则的表现。总睡眠时间和总睡眠时间减去阶段1预测性能较差。总SWS加REM预测性能最好，但不能区分10分钟和2.5小时的条件。 因此得出结论，睡眠连续性理论对数据的解释最为简洁，即睡眠恢复需要超过10分钟的不间断睡眠。
Eight normal adult sleepers spent 4 nonconsecutive weeks in the laboratory. Each week consisted of a baseline night followed by 2 consecutive nights of disrupted sleep, followed by 2 recovery nights. Disruption conditions included: a) brief awakening after each minute of accumulated sleep, b) brief awakening after each 10 min of accumulated sleep, c) 2.5 hrs of normal sleep followed by a brief awakening at each sleep onset, and d) total sleep deprivation. Morning testing revealed that all disruption conditions min disruptions approximately that seen after total sleep loss. Performance decrements were less in the 10-min condition and least in the 2.5-hr sleep condition. Performance under baseline and total sleep loss conditions was used to predict performance during the sleep deprivation condition using four sleep stage rules. Total time asleep and total time asleep minus stage 1 predicted performance poorly. Total SWS plus REM predicted performance best but could not differentiate the 10-min and 2.5-hr conditions. Therefore it was concluded that the data most parsimoniously explained by the Sleep Continuity Theory-i.e, that periods of uninterrupted sleep in excess of 10 min are required for sleep to be restorative.
