Comparison Across Multiple Types of Sleep Deprivation

This fatigue study is designed to assess neurobehavioral performance, as well as biological physiological changes associated with variations in timing and quantity of sleep. Biological indicators of cognitive changes will be assessed among individuals randomly assigned to four separate sleep conditions: a well-rested control, sleep restriction with nighttime sleep, sleep restriction with daytime sleep to roughly simulate shiftwork schedules, and total (acute) sleep deprivation. This study will generate a core deliverable of an internal biological indicator list, and possible extramurally supported additional reports or datasets. Physiological and performance information collected include wearable actigraphy data, polysomnography data, and neurobehavioral performance data.
