Description
OBJECTIVES:
This study addressed the goal of developing tools to assess crew performance in real-time and evaluate countermeasures to mitigate the effects of fatigue, circadian misalignment, and work-overload. It is responsive to the critical need to identify how a range of cognitive functions of astronauts can be affected in space flight by fatigue alone, and its interaction with other risk factors and conditions such as elevated carbon dioxide, intracranial pressure, space fog, and countermeasures. This study aimed to deliver a comprehensive, software-based, neurocognitive toolkit (Cognition). By building on state-of-the-art neuropsychological test development, the toolkit permits evaluation of a full range of cognitive functions using brief (1-5 minutes), validated procedures. The tests included, but went beyond, what is currently measured by WinSCAT and the Reaction Self Test on the International Space Station (ISS). Importantly, the toolkit permitted rapid assessment of performance in cognitive, social-emotional, and sensorimotor domains.

This study had the following specific aims:

  1. Development of short-duration adaptive versions of neuropsychological tests for space flight.
  2. Establish learning curves for neuropsychological tests and validate sensitivity to sleep deprivation.
  3. Cognition software development and optimization for space flight.
  4. NASA’s Johnson Space Center (JSC) field testing, astronaut learning curves, and astronaut norms for performance feedback algorithm development.
  5. Complete ISS feasibility study.

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.

The Human Research Roadmap is located at: https://humanresearchroadmap.nasa.gov/
