A program for studies of altered sleep-wake schedules and performance

Studies of the effects of variations in sleep-wake schedules on human performance tend to run for several days and involve extensive repeated testing in order to take into account time-of-day and cumulative cross-day effects (Broughton & Ogilvie, 1992; Monk, 1991; Webb, 1982). Such research typically addresses issues pertaining to sustained operations and shift work and is often more appropriately conducted in the field. The present paper describes a computer-automated system designed to administer sleep-wake schedules and performance tests, and to store results of such testing in file formats that are easy to access with commercially available statistical packages.
