An experiment was conducted to determine, for extended periods of work, the effects of a working for 48 hours without sleep on the efficiency of the work done, b starting work periods at night compared with starting in the morning, and c rotating jobs. Two-man teams performed a driving task and a target detection task a control group performed the same tasks, but with provisions for sleep. Results indicate that performance deteriorates over a 48-hour period of work without sleep, and that deterioration occurs primarily at night, or during the subjects normal sleeping hours. Job rotation to introduce another activity did not prevent performance decrements.
