[Dynamics of subjective perception of in-group interaction during long-term isolation and confinement]

In experiments HUBES and ECOPSY-95 small groups of test-subjects under the conditions of long-term isolation and confinement were noted to split into two fairly stable parts each consisting of two crew members and an "outsider". Strain in the interaction between the "outsider" and the crew tended to grow in acuity as was evidenced by rise in the criteria describing behavior of a small group, and relationship. In both experiments the background for the conflict-threatening strain appeared to be a disintegrated ego-image in both of the "outsiders". Generally, infantilism of ego-image was in hand with hand with low self-assessment. Development by the subjects of ineffective patterns of the attitude system which we consider to be "escape back to the past" and "disintegration" of ego-image overlapped with the most psychologically challenging periods in the experiments, i.e. the start and the end of isolation and confinement, and off-nominal situations.
