Abstract: Subjects perform a decision task (Grether, 1980) in both a well-rested and experimentally sleep-deprived state. We have two main results: 1) final choice accuracy is unaffected by sleep deprivation, and yet 2) the estimated decision model differs significantly following sleep-deprivation. Following sleep deprivation, subjects place significantly less weight on new information in forming their beliefs. Because the altered decision process still maintains decision accuracy, it may suggest that increased accident and error rates attributed to reduced sleep in modern society stem from reduced auxiliary function performance (e.g., slowed reaction time, reduced motor skills) or other components of decision making, rather than the inability to integrate multiple pieces of information.
