[The dynamics of communicative interaction of the crew with outside parties during long-term isolation]

Analyzed were indices of communicative activity of crew members during audio- and computer sessions in order to assess status and effectiveness of communicative interaction of crew with external parties. The investigation gave another evidence that an isolated small group develops "closing" and "internal censorship" in contacts with outer personnel. The conclusion was based on limited in intensity, number, topical spectrum and outer companion preference communication. These appeared to be parallel to egocentrism manifested by claims on supreme concern, sensitivity to speech tones and matter of massages of outer supporters, and attempted manipulation with the outer personnel. In the course of the experiment, the subjects were getting more into the habit to use the information channels for expansion of their emotional contacts and "dumping" emotions. Differential attitude to different duty teams and selective manner of communication underlie differences in the intensity of crew-ground personnel communication.
