Area of Science:

  • Human Factors and Performance
  • Spaceflight Physiology
  • Human-Computer Interaction

Background:

  • Assessing cognitive and motor performance in high-workload, extreme environments is crucial for space exploration.
  • Previous research has primarily focused on spaceflight conditions, with limited data from isolated environments.

Purpose of the Study:

  • To evaluate cognitive and motor performance in microgravity and extreme isolation using standardized protocols.
  • To investigate the impact of perceptual motor adaptation strategies on human performance in these environments.

Main Methods:

  • Conducted the Mental Workload and Performance Experiment (MWPE) during spaceflight (STS-42) and the Memory Processes and Motor Control (MEMO) experiment during isolation (CAPSULS).
  • Assessed short-term memory using a Sternberg-like task and fine motor control with joystick and trackball interfaces.

  • Tested performance under microgravity adaptation and with reversing prism goggles to simulate sensory-motor challenges.

    • Main Results:

    • Both microgravity adaptation and reversing prism goggles significantly impaired motor performance.
    • Cognitive performance, specifically memory recall, remained unaffected by these environmental stressors.
    • Data from both spaceflight and isolation missions provide complementary insights into human-computer interaction.

    Conclusions:

    • Motor control is more susceptible to environmental disruptions than cognitive functions in extreme settings.
    • Findings enhance understanding of human interface technology for optimizing astronaut performance in space and isolation.
    • Standardized experimental approaches are valuable for comparing performance across diverse extreme environments.
