Abstract : The effects of one night's sleep loss were tested on subjects who were tested again after a night's recovery sleep. Several physiological measures were taken while subjects were administered the AGARD SIRES Battery (to assess performance changes) and the NASA-ThX (a subjective index). In general, all measures showed changes with sleep loss which then recovered with one nighfs sleep. On several of the SIRES Battery tasks, reaction times increased and accuracy decreased after a night without sleep, and then recovered with a night's sleep. Tracking performance especially was consistently affected. Blink rate reliably increased with a night's sleep loss, and recovered with sleep; blink duration tended to increase with sleep loss. Heart rate decreased with sleep loss, while heart rate variability at high and medium bands was found to increase consistently. Power in the EEG alpha band tended to be greater after a night's loss of sleep when it was measured in terms of absolute power and as relative to total EEG power. Evoked potential results were equivocal. Subjectively, subjects ranked the individual SIRES Battery tasks as harder after a night without sleep. Just one night without sleep affected task performance, physiological measures, and subjective assessments of task requirements; recovery generally occurred with one night of sleep.
