Summary
Astronauts exhibit distinct psychophysiological responses in space compared to Earth, altering their regulatory patterns during flight and returning to baseline post-mission.
Area of Science:
- Space physiology
- Psychophysiology
- Human adaptation to space
Background:
- Understanding human physiological and psychological responses during spaceflight is crucial for astronaut health and mission success.
- Previous research indicates significant physiological changes occur in microgravity environments.
Purpose of the Study:
- To investigate psychophysiological reactions of astronauts in space using a comprehensive test battery.
- To analyze changes in regulatory patterns during spaceflight and upon return to Earth.
Main Methods:
- Application of a complex psychophysiological test battery, including electrocardiography (ECG), blood pressure, skin conductance level (SCL), and finger temperature.
- Data collection from two subjects during spaceflight and post-flight.
Main Results:
- Subjects displayed different psychophysiological reactions in space compared to their terrestrial responses.
- Four distinct types of physiological regulation were identified in the collected data.
- The observed regulatory patterns shifted during the spaceflight mission.
Conclusions:
- Space conditions induce unique psychophysiological responses in humans.
- Astronauts demonstrate adaptive regulatory changes during spaceflight.
- These regulatory patterns are reversible, returning to pre-flight norms after landing.
