Task Description: In order to be able to carry out mission-critical tasks at any time during a mission, astronauts must maintain a high level of performance in the face of demanding workloads and work-rest schedules that result in chronic sleep restriction. The proposed research will use a laboratory-based study to acquire critically-needed information on the effects on performance of high cognitive workload and sleep restriction (Specific Aim 1). We will test the hypothesis that as sleep restriction accumulates, it will potentiate the performance-impairing effects of higher cognitive workload. Another key goal of the study is to provide astronauts with an objective way to identify performance changes and the need for countermeasures for fatigue from sleep restriction and high workload. To this end, the project will complete validation of the sensitivity of the 3-minute PVT SelfTest to high workload and sleep restriction. PVT SelfTest feedback interfaces will also be evaluated, and the task will be tested in analog operations to establish its technical feasibility (Specific Aim 2). Tertiary goals of the project include identification of biobehavioral predictors of differential vulnerability to the cognitive effects of sleep restriction and high workload (Specific Aim 3), and development of individualized biomathematical models that predict performance on the PVT SelfTest during high workload (Specific Aim 4). The project has primary relevance to the strategic goals of the NSBRI Human Factors and Performance (HFP) Team. To date N=40 (of the N=80 total subjects to be tested) have completed the laboratory protocol; thus the project is 50% completed. Data acquisition will continue at this rate in the coming year to ensure the project ends with the required number of subjects needed to evaluate the effects of high cognitive workload and sleep restriction on performance.

 

Research Impact/Earth Benefits: The research builds on an extensive body of work we have conducted to help manage the cognitive performance of astronauts in space while they undergo high workload and sleep restriction. The acquisition of critically needed knowledge on how these factors potentiate fatigue effects on performance will help set standards and improve individualized mathematical models that predict countermeasure needs. The continued development of the PVT SelfTest will offer a tool by which astronauts can autonomously assess their performance fitness and make decisions about countermeasures. These deliverables will also have utility in a broad range of Earth-based applications in which sleep restriction and workload have major adverse impacts on human performance (e.g., transportation modes, power plants, military operations).

 

Task Progress: The project is on schedule in terms of recruitment and data collection in the study has occurred without incident. This year, N=20 healthy adults have completed the 11-day experimental protocol (for a total of 220 laboratory days). Thus, collectively across 2 years, N=40 healthy adults have completed the 11-day experimental protocol (for a total of 440 laboratory days). We expect to recruit another 20 subjects (for an additional 220 laboratory days) in the upcoming grant year.

Throughout the 11-day experimental protocol, in which subjects are under continuous behavioral monitoring, we collect a large number of neurobehavioral and physiological tests to determine the effects of cognitive workload. These include the following: the 10-minute Psychomotor Vigilance Test (PVT) and the PVT Self Test, which assess vigilant attention; a modified version of the Maintenance of Wakefulness Test (MWT), which lasts 30 minutes and assesses sleep propensity during waking; the Karolinska Sleepiness Scale (KSS), a Likert-type scale that assesses subjective sleepiness; executive function tests that relate to prefrontal cortex functioning; cardiac measurements of heart rate and heart rate variability; polysomnography; power spectral analysis of non-REM slow-wave activity; waking EEG; and blood draws for biomarker identification.

The project has primary relevance to strategic goals of the NSBRI Human Performance Factors, Sleep and Chronobiology (HPFSC) Team. It addresses a high priority gap identified by the NASA SAT, BHP, and NSBRI HPFSC area, and specifically targets questions 27e,d,f,g in Bioastronautics Roadmap Risk Area 27 (Human Performance Failure Due to Sleep Loss and Circadian Rhythm Problems), questions 26f,g,c,h in Risk Area 26 (Mismatch between Crew Cognitive Capabilities and Task Demands), and question 25d in Risk Area 25 (Human Performance Failure Due to Neurobehavioral Problems). To date N=20 (of the N=80 subjects needed) have completed the laboratory protocol. Data acquisition will continue at this rate in the coming year to ensure the projects end with the required number of subjects needed to evaluate the effects on performance of high cognitive workload and sleep restriction. Data are also being recorded on subjects in the 105-day Russian Chamber Study.

 

Research Impact/Earth Benefits: The research builds on an extensive body of work we have conducted to help manage the cognitive performance of astronauts in space while they undergo high workload and sleep restriction. The acquisition of critically needed knowledge on how these factors potentiate fatigue effects on performance will help set standards and improve individualized mathematical models that predict countermeasure needs.

Task Progress: The project is on schedule and the study is progressing well. N=20 healthy adults have completed the 11-day experimental protocol (for a total of 220 laboratory days) and we expect to recruit another 20 subject in the coming grant year. The PVT SelfTest is being deployed on ISS for astronaut data acquisition on its feedback utility.

Performance Goal Text:

 

Task Description: To be able to carry out mission-critical tasks at any time during a mission, astronauts must maintain a high level of performance in the face of demanding workloads and work-rest schedules that result in chronic sleep restriction.

This project will use a laboratory-based study to acquire critically-needed information on the effects on performance of high cognitive workload and sleep restriction (Specific Aim 1). We will test the hypothesis that as sleep restriction accumulates, it will potentiate the performance-impairing effects of higher cognitive workload.

Another key goal of the study is to provide astronauts with an objective way to identify performance changes and the need for countermeasures for fatigue from sleep restriction and high workload. To this end, the project will complete validation of the sensitivity of the three-minute Psychomotor Vigilance Test (PVT) SelfTest to high workload and sleep restriction. PVT SelfTest feedback interfaces will also be evaluated, and the task will be tested in analog operations (e.g., NASA Extreme Environment Mission Operations - NEEMO) to establish its technical feasibility (Specific Aim 2).

Tertiary goals of the project include identification of biobehavioral predictors of differential vulnerability to the cognitive effects of sleep restriction and high workload (Specific Aim 3), and development of individualized biomathematical models that predict performance on the PVT SelfTest during high workload (Specific Aim 4).

The project has primary relevance to strategic goals of the NSBRI Human Factors and Performance Team. It addresses a high-priority gap identified by NASAs Small Assessment Team and Behavioral Health and Performance Program Element, and NSBRI Human Factors and Performance area. The project specifically targets questions 27 e, d, f, and g in the Bioastronautics Roadmap Risk 27 (Human Performance Failure Due to Sleep Loss and Circadian Rhythm Problems), questions 26 f, g, c, and h in Risk 26 (Mismatch between Crew Cognitive Capabilities and Task Demands), and question 25 d in Risk 25 (Human Performance Failure Due to Neurobehavioral Problems).
