Intervention: Sleep:wake 1 (Behavioral)
Outcomes
Primary Outcomes
Psychomotor Vigilance Task (PVT) performance
Time Frame: PVT during waking for arms 1 and 2 during the 32-day inpatient portion of the protocol
PVT metrics are reaction time. It is measured when the participants are awake during the inpatient portion of the protocol.
