This article discusses issues related to the study of linguistic actualization of modern processes taking place in the world. First of all, we are talking about migration processes that are due to political, economic and social reasons. The increase in international political, scientific, economic, educational, and social contacts, constantly growing migration flows and the formation of migrant enclaves – all that have led to a great interest in the study of migration discourse. The analysis of migration discourse is associated not only with the formation of new approaches to its study, but also with an attempt to attract methods from other areas of linguistics, in particular, psycholinguistics. The article presents the results of a free associative experiment that reflects the concept of "MIGRATION PROCESSES" in the minds of Russian speakers. The study of the linguistic representation of concepts in the minds of native speakers is a trend in linguistic research, as it allows fixing the categories that informants refer to when describing these processes. The article shows the importance of specific categories that are actualized by verbal signs stored in the mental vocabulary of an individual.Keywords: concept, migration processes, associative-verbal field, free associative experiment, migration linguistics, psycholinguistics, modeling.
