To examine the relationship between superior intellectual functioning and physiological patterns and events during sleep, male children (8-12 years old) of superior (mean IQ: 133.3) and average (means IQ: 111.0) intelligence were recorded for five consecutive nights using standard electrographic measures. Compared to normal controls, superior IQ subjects had greater amounts of TST, stage 2, stage 3, total NREM sleep, a longer average NREM cycle length and significantly less average REM density. In addition, significant negative relationships were obtained between full-scale IQ and REM density, and between verbal IQ and REM density. The results suggest that patterns and amounts of sleep stages in superior IQ children do not differ in any dramatic fashion from those of children with average IQ. However, the negative correlations between IQ measures and eye movement density during REM sleep are consonant with previous notions relating eye movement density to waking information processing strategies and suggest a carry-over of such strategies from wakefulness to sleep.
为了研究睡眠期间卓越智力功能与生理模式及事件之间的关系，使用标准脑电图测量方法，对8至12岁智力超常（平均智商：133.3）和智力中等（平均智商：111.0）的男童连续五个晚上进行记录。与正常对照组相比，高智商受试者的总睡眠时间、第二阶段、第三阶段、总非快速眼动睡眠时间更多，平均非快速眼动睡眠周期更长，平均快速眼动睡眠密度显著更低。此外，全量表智商与快速眼动睡眠密度之间、言语智商与快速眼动睡眠密度之间存在显著负相关。结果表明，高智商儿童的睡眠阶段模式和睡眠时间与中等智商儿童并无显著差异。然而，智商测量值与快速眼动睡眠期间眼动密度之间的负相关与之前将眼动密度与清醒时信息处理策略相关联的观点一致，表明此类策略从清醒状态延续至睡眠状态。
