Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Measure the effects of sleep deprivation/sleep restriction on performance using the Psychomotor Vigilance Task (PVT)	Performed at approximately 75 minutes intervals throughout the sleep deprivation and recovery days	8 days
Secondary	Measure simple arithmetic processing using the Mathematical Processing Subtest of the Automated Neuropsychological Assessment Metrics 4 (ANAM4)	Computer based series of mathematical calculations	5 days
Secondary	Measure current mood states using the Mood Analogue Scale (MAS)	Computer based self adjective checklist of measure mood states	5 days
Secondary	Measure latency to sleep using the Maintenance of Wakefulness Test (MWT)	Subjects will be escorted to their individual darkened, sound-attenuated bedrooms and allowed to lie down on their beds. They will be instructed to close their eyes and try to remain awake. Polysomnography will be monitored online.	5 days
Secondary	Measure alertness using the Karolinska Sleepiness Scale (KSS)	Computer based self rated level of sleepiness	5 days
Secondary	Measure various aspects of mood using the Walter Reed Army Institute of Research (WRAIR) Mood Battery	Computer based battery testing various aspects of mood	5 days
Secondary	Measure various aspects of Sleep and Wakefulness using Polysomnographic measurements with video	Sleep will be measured during the night using polysomnography	5 days
Secondary	Measure various aspects of Sleep and Wakefulness using Actigraphy	A watch-like device called an actigraph will measure movement to determine wake and sleep	22 days
