[Establishing a psychophysiological criterion for the prognosis of the efficiency of the adaptation process].

This paper presents a criterion for measuring the efficiency of adaptation to an altered environment. The criterion is related to the quantitative evaluation of memory adequacy at early stages of the exposure to a new environment. An improvement in the reproduction of emotional words and a slight deterioration of the recollection of neutral words may be regarded as a prognostically significant criterion of the adaptation success. The lack of an improvement in the reproduction of emotionally important information and a significant deterioration of the recollection of neutral information at early stages of adaptation is an adverse sign predicting a potential failure of the adaptation process.
