Group dynamics during the EXEMSI isolation study. Experimental Campaign for the European Manned Space Infrastructure

Area of Science:

• Space Psychology
• Human Factors Engineering
• Sociology

Background:

• Investigating crew dynamics during long-duration isolation is crucial for space mission success.
• Understanding social behavior, interrelations, and team formation in confined environments is essential.
• Assessing the effectiveness of various psychological assessment methods in simulated spaceflight is needed.

Purpose of the Study:

• To investigate crew social behavior, cohesion, and efficiency during 60 days of isolation.
• To critically compare diverse test methods for assessing crew dynamics.
• To provide recommendations for crew selection, training, and support in future isolation studies.

Main Methods:

• A three-phase study (pre-isolation, isolation, post-isolation) involving individual and group assessments.
• Utilized direct (questionnaires, tests) and indirect (behavioral observations) methods with cognitive, affective-emotional, and social components.
• Employed quantitative, qualitative, and mixed-methods approaches to analyze crew interactions and stress manifestations.

Main Results:

• Pre-isolation confidence in team capability was high, with a seemingly uncontested leadership.
• Apparent harmony during isolation masked underlying issues; cohesion was maintained by opposing external authority.
• No clear stress manifestations were observed, but confinement was perceived as a major stressor; sociometric data revealed superficial harmony.

Conclusions:

• Apparent crew harmony in isolation may not translate to real-world spaceflight effectiveness or persist under crisis conditions.
• Group methods, non-obstructive, indirect, and qualitative tools are most reliable for assessing crew dynamics.
• Recommendations emphasize clear communication, defined objectives, and fostering cooperative relations for improved crew selection and support.
