Study of values and interpersonal perception in cosmonauts on board of international space station

The increased heterogeneity of International Space Station (ISS) crews' composition (in terms of nationality, profession and gender) together with stressful situations, due to space flight, can have a significant impact on group interaction and cohesion, as well as on communications with Mission Control Center (MCC) and the success of the mission as a whole. Culturally related differences in values, goals, and behavioral norms could influence mutual perception and, thus, cohesive group formation. The purpose of onboard Interaction-Attitudes experiment is to study the patterns of small group (space crew) behavior in extended space flight Onboard studies were performed in the course of ISS Missions 19-30 with participation of twelve Russian crewmembers. Experimental schedule included 3 phases: preflight training and Baseline Data Collection; inflight activities once in two weeks; post-flight measurement. We used Personal Self-Perception and Attitudes (PSPA) software for analyzing subjects' attitudes toward social environment (crewmembers and MCC). It is based on the semantic differential and the repertory grid technique. To study the content of interpersonal perception we used content-analysis with participation of the experts, independently attributing each construct to the 17 semantic categories, which were described in our previous study. The data obtained demonstrated that the system of values and personal attitudes in the majority of participated cosmonauts remained mostly stable under stress-factors of extended space flight Content-analysis of the important criteria elaborated by the subjects for evaluation of their social environment, showed that the most valuable personal traits for cosmonauts were those that provided the successful fulfillment of professional activity (motivation, intellectual level, knowledge, and self-discipline) and good social relationships (sociability, friendship, and tolerance), as well. Post-flight study of changes in perceptions, related to Real Self-image, did not reveal significant differences between the images of Russian crew-members and representatives from foreign space agencies. A certain difference in perceptions was found in cosmonauts with more integrated system of evaluations: after space flight they perceived foreign participants as closer to their Ideal, while Russian crew-members were perceived mostly as distant from Ideal Self of these subjects. Perceptions of people from Earth were also more critical. These differences are likely to be manifestations of interpersonal perception stereotypes. Described patterns of changes in perceptions of cosmonauts, who have performed space flight as a part of ISS multinational crew, allow us to suggest the recommendations for development of ISS crew training, in particular, it seems useful to increase the time of joint training for deepening of intercultural interaction.
