At the same time, not only the new effective technologies of teaching foreign languages, but also the psychological support of the educational process is of great importance. The mechanisms of external and internal motivation and demotivation in the study of foreign languages are considered. The effectiveness of combining mathematical modeling of the structure of a language and its emotional-figurative perception is shown. The expediency of further studies of this in assessing the effectiveness of learning foreign languages in the long term is justified.
