Individual strategies of human adaptation under extreme conditions.

Starting from the investigations of Sechenov, Pavlov, and Uchtomsky, the Russian psychophysiological school has been considering adaptation in connection with the biological and social origin of the person (human as a rational being) as an integrated, coordinated, and self-controlled system. On the basis of the problem of man and the environment, Medvedev added to the theory of human adaptation the activity paradigm that enables us to uncover the distinctive features of occupational activities under various environment conditions. The theoretical and practical investigations based on the activity methodology presented the opportunity to find new principles of interaction between man and the environment and of the strategy of adaptive behavior. From the investigations one could see that the main characteristic of the human-environment interaction is that the active factor is the human who could simulate different adaptation strategies.
