The analysis of space crew's communication with mission control (MC) is the standard operational procedure of the psychological support group in the Institute for Biomedical problems, Russia. For more than 20 years it is used for the distant monitoring of the behavioral health of Russian crewmembers in space. IBMP psychological support group apply quantitative speech content analysis to reveal relationship dynamics within the group and between the crew and MC, psycho-logical emotional status and individuality of communicator, his coping strategy.
The essential principle of content-analysis is to present the communication content by the special code, consisting of scientifically determined categories. We regard statement, the completely ex-pressed idea, as communication unit. Further all the statements are coded with the certain con-tent categories, important for communication structure of the autonomous crew (Activity, Needs, Social regulation, etc.). That makes the analysis quantitative, still dependant on the expert perso-nality. The NOOJ Linguistic Development Environment (Silberztein, 2008) is the software that is able to map the linquistic and compositional/structural features of texts in order to explore psychological states, processes and changes. Using NOOJ for the psychological analysis of communication helps to make content-analysis quantitative, rapid and more objective.
Distant monitoring procedure was used for the analysis of written daily reports in Mars-105 space simulation. Mars-105 experiment was a chamber simulation of the first stage of Manned Mars Mission. The crew of 4 Russians and 2 Europeans spent 105 days in hermetic modules, accom-plishing a sophisticated scientific Protocol. In this study for the first time written crew reports in Russian were processed with NOOJ. Software automatically detected and calculated the words, expressing crew Activity, Needs and Social regulation, thus attributing each statement of the report to one of these psychological categories.
In Mars–105 content analysis of daily written reports allowed to find out the specific influence of autonomous conditions on the individual style of communication with MC, as well as on the gen-eral behavioral coping strategies. These results demonstrated the scientific potential of a new ob-jective method of crews’ dynamic psychological monitoring.
