对12名正常的55-70岁和年轻成人受试者进行实验，他们的睡眠以每小时大约14次的速度中断，以确定中度睡眠干扰的残余影响，并确定作为年龄函数的任何不同影响。在基线和恢复之夜，睡眠出现了正常的年龄相关变化。在睡眠障碍的第二个晚上，老年受试者的总觉醒次数比年轻人增加得更少。随着睡眠障碍的进展，年龄较大的受试者听觉唤醒阈值的增加速度较慢。与年轻人相比，年龄较大的受试者在晨间测试中的表现恶化程度也较小，这种差异对于正确完成加法问题的数量来说是显著的。这些证据得出的结论是，虽然两个年龄段的人对中度睡眠障碍都很敏感，但老年人似乎比年轻人更不敏感。
Groups of 12 normal 55-70-old and young adult subjects had their sleep experimentally distubed at a rate of approximately 14 times per hour to determine the residual effects of moderate sleep disturbance and to determine any differential impact as a function of age. Normal age-related changes in sleep were seen on baseline and recovery nights. In the second night of sleep disturbance, the older subjects has a smaller increase in total awakenings than young adults. Older subjects had a slower increase in auditory arousal threshold as sleep disturbance progressed. The older subjects also tended to have less performance deterioratio n on morning testing than did young adults, and this difference was significant for numbers of correctly completed addition problems. These evidences led to the conclusion that, while both age groups were sensitive to moderate sleep disturbance, the older individuals appeared somewhat less sensitive than the young adults.
