Abstract: The article is devoted to the problem of internationalism and isolationism of the domestic psychology of the first half of the XX century. The object of the study is the international trends in the development of domestic practice-oriented psychology, and the subject is international scientific communication as a condition for the development of the main scientific and practical trends in the domestic psychology of the period studied. An original approach to solving the problem is proposed in the context of the idea of a self-developing collective subject of scientific knowledge involved in the system of international scientific communication. The method of historical and psychological reconstruction is being implemented. The results of the analysis of data on international cooperation in the course of the organization of scientific and practical trends, as well as on official and informal contacts of the leading representatives of Soviet pedology, psychotechnology and psychoanalysis with foreign scientists are presented. The novelty of the study consists in revealing the specifics and role of the general social and scientific and social conditions in the implementation of the inter-ethnic scientific communication of domestic psychologists: the significance of not only social need is determined (in increasing labor productivity, educating a new person, theoretical and ideological justification of social transformations, recognition and strengthening of political positions of the Soviet state abroad), but also scientific policy in relation to the scientific and practical trends of psychology ii. Conclusions are drawn about the close relationship of international scientific communication, Soviet science policy and the processes of institutionalization of domestic scientific and practical trends in the 1920s.

Abstract: The authors of the article define the problem of the relation between fundamental, applied and practical branches of psychology. Based on the analysis of V.A. Koltsova, T.D. Martsinkovskaya, O.G. Noskova, T. Leahy, R. Smith and other Russian and foreign historians, the authors provide the overview of the history of formation and development of applied and practical trends in psychology, especially pedology and psychotechnics. For the analysis of the historical-scientific and methodological patterns, the authors use the dynamic model of the relationship between theoretical psychology and social practice through the development of applied psychology developed by L.S. Vygotsky. More recent periods of relations between Russian fundamental psychology and psychological practice are viewed based on the conceptual grounds offered by A.L. Zhuravlev, D.V. Ushakov, A.G. Liders and I.N. Karitsky. The opportunities to distinguish applied and practical branches of psychology in the practical activity of psychologists are revealed so is the concept of role-playing ring proposed by Y.M. Zhukov. As a result, the structure of the relationship between subject and object of psychological activity is determined as an important base of classification of these branches. Historical analysis of the development of practical and applied branches of psychology in the first half of the XX century allows us to formulate a hypothesis about the singleness of the basic patterns of their development.
