The article presents the results of preliminary psycholinguistic experiment. It has been established that concepts differ depending on culture. They represent clusters of cultural information in human consciousness. They can change depending on both linguistic and extralinguistic circumstances. The results of the experiment reveal the associations Russian students have with the word “мистический” (“mysterious”). Young people are influenced by cultural globalization most of all. Verbalized in the form of words / phrases these associations reveal the cultural changes of the last 30 years. The obtained results show that students demonstrated many associations which were not typical for Russian culture some decades ago. Associations they gave denote mysterious things, notions, places, people, etc. borrowed from American culture by means of language. The students pointed out few words which denote specific mysterious things, notions, etc typical for Russian culture only (such as водяной, леший, берегиня).
