Thirty young male volunteers participated in a study of sustained continuous performance using a variety of computer-based tasks. After 6 hrs of recorded sleep, 10 subjects were assigned to perform continuously for 42 hrs without break. Three of these subjects were unable to complete the 42-hr assignment, and 8 of the 10 suffered psychological events such as hallucinations and disorientation. Ten subjects permitted six 1-hr naps over the 42 hrs performed more successfully than those allowed no sleep. Ten subjects permitted one 6-hr rest period performed best of all. Fatigue effects appeared after 6 hrs. Time-of-day (circadian) effects were at times stronger than fatigue.
