Abstract
Subjects worked 30 to 45 min. of each hour for either 48 ( n = 2) or 2 hr. ( n = 8) without sleep. The frequency of reported visual task-related perceptual distortions and hallucinations showed both a linear increasing component and a strong circadian component. Perceptual distortions were most frequent in the late night-early morning hours (0400) and least frequent in the late afternoon-early evening hours (1600–2000).
