Аннотация:The study aims at identifying individual language learning strategies that allow a polyglot to effectively communicate with unfamiliar native speakers on spontaneous topics within a short learning period of 100 days. The study was conducted over 1000 days (September 2018 - June 2021) of observing Alan Bigulov (the polyglot from Vladikavkaz, Russia) in the process of learning 10 new, typologically different languages. The theoretical framework of the study was the psycholinguistic expert performance modeling – in this case, the psycholinguistic monitoring of a person, especially effective in the time management of language learning. Methodologically, the study focused on close monitoring of daily video recordings of Alan Bigulov's communication in the target language, weekly correspondence in the format of the researcher's questions and the subject's answers, and in the linguistic analysis of the subject’s evaluative predicates during the whole 1000-day Project. The main results of the research have elicited the following patterns: consistent focus on one language; three-level model of a spiral entry into a communicative situation; the effectiveness of the super-intensive start; deliberate wave-like variation of the intensity of classes; the importance of flexible algorithms of language classes aimed at avoiding routine and reaching a new level of intensity.
