Adaptive Stress Training for Hazardous Conditions (80NSSC18K1572)
Principal Investigator
Research Area:
Behavior and performance
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Acute stress has the potential to significantly debilitate human performance, both physically and cognitively. For long-duration space flight, the results of such reduced cognitive performance could be life-threatening, and therefore warrants the creation of behavioral countermeasures for mitigating crew health and performance risks. Currently most emergency training focuses on performance outcomes, but new research should be centered on preventing negative performance outcomes through acute stress management techniques. Traditional training can be effective under predictable conditions, but performance can degrade rapidly if unexpected stressors are introduced. Additionally, the proposed system can serve as a preflight screening measure to help identify individuals who are more likely to perform better in high stress situations. The goal of this experiment, using Virtual Reality (VR) simulated situations, is to reduce acute stress response during space flight using an adaptive inoculation approach. Exposure will be administered gradually and will use a biofeedback system to respond and adapt to individual stress response in a way that promotes learning voluntary physiological control without overwhelming the subject.

Specific aims of this research include:

  1. Identifying stressors in a microgravity environment;
  2. Evaluating formal objective methods to measure baseline chronic and acute stress, in-training performance, psychological stress response, physiological stress response, and procedural errors;
  3. Developing a prototype for graduated stress training;
  4. Conducting a proof-of-concept of the training program based on NASA’s emergency protocols for the International Space Station (ISS); and
  5. Establishing guidelines for implementation of the graduated stress training.

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit. The Human Research Program (HRP) investigates and mitigates the highest risks to human health and performance, providing essential countermeasures and technologies for human space exploration. Risks include physiological and performance effects from hazards such as radiation, altered gravity, and hostile environments, as well as unique challenges in medical support, human factors, and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify the approach and research activities planned to address these risks, which are assigned to specific Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.
