Aims:
Traditional emergency training practices are focused on performance outcomes, research into countermeasures should investigate stress-training techniques for acute stress in life-threatening situations to prevent adverse behavior and performance degradation. Recent advances in virtual reality (VR) environments provide the capability to simulate stressors over multiple sessions in a realistic task setting, until realistic stress levels are achieved. A virtual reality training system that is able to adapt based on the crew member's stress response may help foster resilience. By measuring participant's physiological and performance metrics, the adaptive system would allow graduated exposure of stress levels within a suitable biometric and performance ranges. Activating the stress response, while simultaneously assuring the crew member is not overwhelmed, may facilitate inoculation to the stress. Further, the automated training would be beneficial during long duration missions where ground support and training resources are limited or unavailable. This research aims at measuring physiological stress response and in-training performance, while evaluating adaptation rules and triggers. By using stress training to familiarize and prepare crew members for future stressors, a reduced state of anxiety and increased cognitive resources enabling enhanced performance are expected. Aims include:

1. Identify components and principles that contribute to the stress in a microgravity environment;
2. Evaluate formal objective methods to measure and adapt for baseline chronic and acute stress, in-training performance, psychological stress response, lapse in judgment, and other errors during the adaptive stress training;
3. Develop a prototype for graduated stress training by evaluating adaptation rules, triggers, other state assessment in combination with biometric feedback;
4. Conduct a proof-of-concept of the training for hazardous conditions through implementation of the training on emergency procedures for the NASA International Space Station (ISS) with subsequent testing of the training in a full-scale virtual-reality ISS’ simulations; and
5. Establish guidelines for implementation of the graduated stress.

RiskRisk of Adverse Cognitive or Behavioral Conditions and Psychiatric Disorders
GapBMed-101: We need to identify, quantify, and validate the key selection factors for astronaut cognitive and behavioral strengths (e.g., resiliency) and operationally-relevant performance threats for increasingly Earth independent, long-duration, autonomous, and/or long-distance exploration missions.
GapBMed-103: What are the validated, efficacious treatments (individual or Team-based) and/or countermeasures to prevent adverse behavioral conditions, CNS/neurological, and/or psychiatric disorders caused by either single and/or integrated exposures to spaceflight hazards during exploration class missions?
GapBMed-104: Given the potentially negative spaceflight associated CNS changes and behavioral experiences of stressors during long-duration missions (e.g., isolation, confinement, reduced sensory stimulation, altered gravity, space radiation), what are validated modifications to habitat/vehicle to mitigate stressors impacting on CNS / cognition / behavioral health?
GapBMed-105: Given the potentially negative spaceflight associated CNS/cognitive changes and behavioral experiences of stressors during long-duration missions (e.g., isolation, confinement, reduced sensory stimulation, altered gravity, space radiation), what are validated medical or dietary countermeasures to mitigate stressors impacting on CNS / cognition / behavioral health?
GapBMed-107: What are the long-term changes and risks to astronaut health post-mission that, when using a continuity of care model, helps retrospectively identify and understand individual susceptibility (e.g., hereditary, dose, thresholds) to mitigate adverse CNS, cognitive, and behavioral health changes resulting from long-duration exploration missions, promoting the behavioral health of current and future crews?
