Moreno, method of distributing topics by rank, questionnaire. The authors of the article analysed scientific works on the research problem, clarified the concept of "adaptation" and "adaptability" and age limits of the groups of winterers, described methodological tools and conducted empirical research on the specific features of the age of winterers groups during the adaptation. The article justifies the distribution and identifies groups of high, medium and low adaptability to life under extreme conditions in Antarctica. The authors analysed both the data from the empirical study and the interviews with the surveyed winterers. The study's conclusions are: senior winterers have more experience adapting to extreme conditions than younger generations. They can build better interpersonal relationships in a closed community and easily carry distance from home and homesickness. The study revealed that senior persons (especially representatives of the "Generation of winners' children") motivate wintering in Antarctica with a desire for self-fulfilment, being worthy representatives of Ukraine on a distant continent, and feeling responsible for discharging their duties. After all, they are governed by more professional and social motivations that help to better adapt to extreme conditions. The practical value of the work is to develop tools for psychological diagnosis and to provide guidance on the selection of winterers among candidates for wintering
