There is a need to develop new psychological and pedagogical methods that improve the quality of learning new information, and take into account the individual personal characteristics of students. This article explores the changes in the structure of the relationships between cognitive states and emotional experiences during lessons where the new teaching material is perceived by the students as easy to understand and when the new information seems difficult. A survey was conducted with 60 high school students and 45 third-year students at KFU. The study showed the general psychological regularities of individual cognitive states and the emotional dynamic. It established a relationship between the time factor, the subjective evaluation of the quality of perception of new information and the general emotional well-being in high school students and students. The conclusions provide a basis for the new strategy for the provision of educational information.
