The stereotyped behaviours of six institutionalized handicapped children were continuously observed during several days. Each child showed at least two forms of stereotyped behaviour. Using spectra of variance and cross-correlation analysis, the data were analysed with respect to underlying periodicities. A 2.5-hour cycle was found in all observed stereotypies. Furthermore, stable phase relationships were found between the periodic variations of different stereotypies in one and the same child. The temporal courses of hand and oral stereotypies were synchronous but head and whole-body stereotypies were delayed by half a phase with respect to sterotypic handwaving. A possible relationship is discussed between the 2.5-hour periodicity of stereotyped behaviour and Kleitman's "Basic Rest Activity Cycle."
在几天时间里持续观察了六名收容机构中的残疾儿童的刻板行为。每个孩子至少表现出两种刻板行为形式。使用方差谱和互相关分析，对数据进行了潜在周期性方面的分析。在所有观察到的刻板行为中都发现了一个2.5小时的周期。此外，在同一个孩子的不同刻板行为的周期性变化之间发现了稳定的相位关系。手部和口部刻板行为的时间进程是同步的，但头部和全身刻板行为相对于刻板的挥手动作延迟了半个相位。讨论了刻板行为的2.5小时周期性与克莱特曼的“基本休息活动周期”之间可能存在的关系。
