Abstract (in Japanese) (See Japanese page) 
(in English) The present study proposes a one-dimensional map of irregular sleep-wake cycle in autistic children. The autism is generally characterized by following behavioral symptoms: impairment in social interaction, communication deficits, and restricted, repetitive behaviors. No little number of children with autism also experience sleep problems. Those are a large fluctuation of sleep onset and awakening time, frequent night waking, and shorten night sleep. The present one-dimensional map of sleep-wake cycle of children with autism consists of functions of a sleep onset-awakening time and an awakening time-sleep onset. Under a certain parameter set, the one-dimensional map showed a large fluctuation of sleep onset and a greater fragmentation of sleep. The max length of sleep was also replicated.
