0229 Reward motivation improves placekeeping performance after total sleep deprivation and a night of rest

Abstract Introduction Sleep deprivation impairs some higher-order cognitive processes, but it is unclear if this reflects impaired ability to perform complex tasks, a reduction in motivation, or both. There evidence that reward motivation attenuates the effect of sleep on lower-level namely vigilant attention. We investigated extent which would mitigate placekeeping, process plays central role accurate performance procedural tasks. To conduct study under pandemic conditions, we developed novel method research remotely. Methods Participants (N = 414) joined Zoom meeting evening and completed Psychomotor Vigilance Task (PVT) placekeeping task (UNRAVEL). At 00:00, randomly assigned participants stay awake overnight (Deprivation) leave (Rested). Two trained researchers stayed monitor participants. 08:30, Rested re-joined meeting, all PVT UNRAVEL again. Some (Motivated), not others (Nonmotivated), could earn monetary based their morning accuracy. Performance was before manipulation. Results examined accuracy using 2 (Sleep: Deprivation, Rested) x (Reward: Motivated, Nonmotivated) between-participants design with as covariate. Deprivation made more errors than participants, Motivated fewer Nonmotivated there no interaction between factors. Conclusion Motivational interventions may be an effective way effects However, affected similarly, and, therefore, did compensate for impairments specific deprivation. Consistent results studies testing naps caffeine, present suggest sequence accurately difficult mitigate. Support (if any) This work funded by Office Naval Research (N00014-20-1-2739).
