在四组正常男性受试者-儿童，青春期前，青少年，和年轻的成年人在睡眠过程中的听觉唤醒阈值的发展变化进行了研究。在两个不受干扰的睡眠适应夜之后的一个晚上，在NREM和REM睡眠期间确定通过耳机插入物呈现的音调的唤醒阈值。觉醒频率和刺激强度所需的影响觉醒，觉醒发生更频繁地响应较低的刺激强度随着年龄的增长，观察到与睡眠相关的关系。虽然唤醒所需的刺激强度很高，在非成年人的睡眠阶段之间具有统计学上的等效性，但相对于成年人的第2阶段和REM睡眠，第4阶段需要更高强度的刺激。这些结果证实了以前的观察显着的阻力觉醒在睡眠中的青春期前的儿童，并建议从睡眠中醒来的过程进行系统的修改在个体发育。
Developmental variations in auditory arousal thresholds during sleep were investigated in four groups of normal male subjects - children, preadolescents, adolescents, and young adults. Arousal thresholds were determined during NREM and REM sleep for tones presented via earphone insert on a single night following two adaptation nights of undisturbed sleep. Age-related relationships were observed for both awakening frequency and stimulus intensity required to effect awakening, with awakenings occurring more frequently in response to lower stimulus intensities with increasing age. Although stimulus intensities required for awakening were high and statistically equivalent across sleep stages in nonadults, higher intensity stimuli were required in Stage 4 relative to Stage 2 and REM sleep in adults. These results confirm previous observations of marked resistance to awakening during sleep in preadolescent children and suggest that processes underlying awakening from sleep undergo systematic modification during ontogenetic development.
