Neurobiological preconditions of behavioural adaptive strategies under extreme conditions of activity

The aim of the work was to identify neurobiological preconditions of efficiency behavioural adaptive strategies of subjects under extreme conditions of activity. The research used an instrumental study technique of making decisions under conditions of choosing among several alternative reactions. Psychodiagnostic testing was performed using blank methods: MMPI (Minnesota Multiphasic Personality Inventory), Cattell's 16 PF (Sixteen Personality Factor Questionnaire). The most sensitive marker of activity in extreme conditions with a high degree of uncertainty according to a number of criteria: time, weakly determined by the method of achieving the result is accidental selection method. Maximum activity efficiency demonstrate subjects who use «repeated» and «repeated N times in a row» behavior strategies. Probably, the set of response options to a situation which a subject has in his/her memory allows subjects to perform tasks in the shortest time. Such behavioural strategy leads to a decrease in the level of uncertainty of the environment, which can effectively prevent the damaging effects of stress, change negative emotions to positive, to act as a non-specific motive for various forms of behavior.
