Group dynamics and crew interaction during isolation.

Abstract

The Homeostat test system was used to determine the interaction effectiveness of the chamber crew during isolation. The group had a complex and unique structure, reflected in the fact that all four subjects expressed considerable leadership activity. The course of the Homeostat task solution parameters testifies to the formation of an intergroup communicative net, which was not completed. This phenomenon was accompanied by emotional tension in the group. The individual contributions to the interaction were investigated. The crew represents a small group with a complex communicative structure. This was due to the presence of above normal leadership activity in all four crew members. The complex course of the leadership activity parameter and the presence of elements of group management allow us to label the crew as a complementary group, which is capable of coping with a wide range of tasks in problem situations. At the same time, the complex group structure caused a certain level of emotional tension in the group. This tension was drained to the outside world by conflicts with the project management. Subjects B and H played a positive role in the reduction of intergroup tension.
