Crew isolation in hyperbaric chambers revealed declining group functioning and interpersonal conflicts, particularly around project management. These issues, similar to previous space mission studies, highlight the need for crew compatibility training and monitoring.

Area of Science:

  • Space exploration psychology
  • Human factors in extreme environments
  • Crew dynamics and performance

Background:

  • Understanding crew dynamics is crucial for long-duration space missions.
  • Previous research, including the ISEMSI study, identified interpersonal issues in isolated crews.

Purpose of the Study:

  • To investigate changes in group functioning, crew relations, and interpersonal interactions during a 60-day hyperbaric chamber isolation.
  • To identify specific challenges and potential solutions for crew cohesion in simulated space environments.

Main Methods:

  • A crew of four was isolated in hyperbaric chambers.
  • Data collection involved communication analysis, peer ratings, questionnaires, and post-isolation interviews.

Main Results:

  • Group functioning declined at multiple points during isolation.
  • Conflicts frequently centered on project management, with a tendency to deny issues, leading to groupthink.
  • Social factors became more important than task-related factors by the end of the isolation.
  • Interpersonal antagonism and withdrawal were observed between crew members.

Conclusions:

  • Interpersonal issues identified in this study are relevant to actual space missions.
  • Behavioral training, crew compatibility assessment, and in-flight monitoring can mitigate problems.
  • Improved training for ground and chamber crews, especially regarding management adjustment and formalized rules, is recommended for future simulations.
