The relevance of the study of the phenomenon of «giftedness» is due to the fundamental importance of this category, from the conceptual interpretation of which it is expected to solve many key problems not only in the psychology and pedagogy of education, but also in other sciences. Despite the fact that the study of giftedness of children has a long history of psychological and pedagogical history, there is no unity in the definition of the concept of "giftedness," and there is no unified theory of the giftedness of children, which would have a holistic view of their giftedness. Despite a close and lengthy consideration of the phenomenon of giftedness, the very essence of giftedness, approaches to diagnosis, the interrelation of health and abilities, the impact of mental stress on children's health, the purposeful process of formation and development of talent of a different age and gender have not been sufficiently studied. The presentation of the importance of studying the individual characteristics of mental loads of gifted children will contribute to the development of applied educational technologies.
