NICOP - The Impact of Sleep Restriction and Circadian Misalignment on Decision Making
Abstract
Technical Description: Increasingly in today~s military, individuals function without adequatesleep and/or are awake and functionin"g during their biological night. Such sleep loss and circadianmisalignment have significant consequences. Sleep loss and circadian" disruption reduceoperational readiness, and are both risk factors for occupational accidents and injury, increasedrate accidents"" among drivers and pilots, and contribute to impaired physician performance andworse patient outcomes. All of these consequences ca""n likely be related, in part, to decisions madeunder conditions of sleep deprivation and/or circadian misalignment. A plethora of s""tudies havedocumented sleep loss and/or circadian related impairments in a variety cognitive domains,including attention, memory,"" working memory, and various executive functions. Despite thesewell documented findings, relatively little empirical work has inves"tigated how decision makingis impacted by sleep deprivation and/or circadian rhythms. There is a critical need for suchinformation", so we can better understand how these realities so common in operational settingsimpact decisions. The current project will be th""e first to systematically assess the effects ofsleep restriction, circadian misalignment, and the combination of both on specificc"omponents of decision making. The sleep manipulations are designed to mirror common typesof sleep disruptions experienced in the mi"litary, and we will utilize well developed decision tasksmeasuring core components of decision making relevant for operational sett"ings. We will comparedecision making during a well-rested state to 3 experimental conditions; 1) sleep restriction; 2)circadian misalignment and 3) combined sleep restriction + circadian misalignment. Decision taskswill measure: a) integration of multiple pieces of information into a single decision; b) strategicreasoning during decisions; and c) strategic interactions with others.Relevance to ONR: The proposal speaks directly to the Discovery & Invention component ofONR~s Science and Technology strategic portfolio a"nd addresses the goals of the WarfighterPerformance program. Specifically, the Human and Bioengineered Systems division explicitly"calls for research: a) to help ~enhanced decision making in all environments~; b) ~based uponfundamental understanding gained from" cognitive and neuroscience~; and c) ~supportingintegrated interdisciplinary research programs~. In response to those needs, this p"roject will: a)enhance our understanding of decision making in the adverse operational context of sleep andcircadian disruption; b) increase our understanding of relevant cognitive science; and c) supportinterdisciplinary research by bringing together sleep and" circadian science, cognitive science, anddecision science. In addition to ONR~s strategic priorities, this project is aligned with"" the 2013SEAL Sleep Working Group Recommendations. Dr. Drummond (PI) served on the SEAL SleepWorking Group, whose charge was to pr"ovide evidence-based recommendations to enhance sleephealth in the SEAL community. This project is most relevant for two of those recommendations:1) develop a force-wide sleep policy including education on the consequences of insufficient sleep;and 2) initiate" a sleep research program, again focused on studying the consequences of insufficientsleep for Navy-relevant performance outcomes.""US Collaborators: David L. Dickinson, PhD, Appalachian State UniversityDesired Outcomes: a) 1-3 peer reviewed journal articles; b)" 4-5 conference presentations
