Stereotyped acts of a mentally defective girl. 6;6 years old, were observed from 6 a.m. till 8 p.m. during 16 days. Alternating phases of more or less frequent stereotyped hand waving showed a prominent periodicity of about 90 minutes. Sleep stages were also determined polygraphically during 10 nights. As statistically proved the mean peak-to-peak interval of the stereotyped activity at days corresponded to the mean REM- to REM period of nights. This suggests, that the stereotyped behavior of this child was driven by the basic rest activity cycle already described by Kleitman. The mean periodicity of sleep stages was represented by modeled rhythms adapted to the scored sleep stages. If the model rhythms of all 10 nights were extended backward to the preceding days, they paralleled the stereotyped activity. Half periods found in phase with REM stages corresponded to the maxima of the stereotyped activity. It will be discussed that the basic rest activity cycle triggers sensory as well as motor mechanisms characterizing both the phases of enhanced stereotyped activity and REM stages.
对一名6岁6个月大的智力缺陷女孩的刻板行为进行了观察,观察时间为早上6点至晚上8点,持续了16天。交替出现的或多或少频繁的刻板挥手阶段显示出约90分钟的显著周期性。在10个晚上还通过多导睡眠图测定了睡眠阶段。经统计学证明,白天刻板活动的平均峰峰值间隔与夜间快速眼动到快速眼动的平均周期相对应。这表明,这个孩子的刻板行为是由克莱特曼已经描述过的基本休息活动周期驱动的。睡眠阶段的平均周期性由适应评分睡眠阶段的模拟节律表示。如果将所有10个晚上的模拟节律向前延伸到前几天,它们与刻板活动平行。与快速眼动阶段同步发现的半周期与刻板活动的最大值相对应。将讨论基本休息活动周期如何触发感觉和运动机制,这些机制既表征了刻板活动增强阶段,也表征了快速眼动阶段。
