Abstract:
Evaluation of the dynamics of in-group strain was conducted with conjunction with the 90-day modelling of space flight (ECOPSY-95). Baseline were the data of sociometric testing and analysis of video records of movements and behavior of the main and visiting crews (three members in each). Global assessment of the in-group strain was made on integration of experimental data using the Czech procedure of interdisciplinary approach to description of a social system, and the theory of fuzzy aggregate. The procedure allows to visualize interpersonal relations as social maps. Reaction to the psychoemotional strain stemmed from long stay in isolation was manifested by gradual build-up of interpersonal strain, redistribution of the functional/role structure of the crew, destabilization of in-group interactions and its split.
