The study of mental verbs is relevant at the present stage of development of linguistic science, since there is still no clear classification of these lexical units in the Kazakh language. The purpose of this study was formed — the representation of the lexical-semantic categories of verbs associated with the processes of perception, cognition and affectivity, using frame model. To implement the tasks set in the study, the methods of frame, semantic, contextual and structural analysis, dictionary and thesaurus approaches used in combination were used. The article examined the main lexico-semantic categories of verbs expressing actions with mental meanings, focused on the formation of frame structures and substructures, evaluated the linguistic capabilities of the three main lexico-semantic categories (perception, cognition, affectivity), formed semantic links between functional-semantic fields each individual group representing different aspects of mental activity. Attention was focused on the fact that the processes of semantic changes are determined by the worldview of the people, their spiritual and cultural experience, and the discursive nature of the language. An idea was formed about the system of mental verbs, representing all types of knowledge, on the basis of the corpus of the Kazakh language and artistic material. This study showed that the Kazakh language is characterised by a high degree of figurativeness, metaphorisation and anthropomorphisation, determined the semantic boundaries of the main groups of mental verbs, so it can be used in the future to form frame models in the field of Kazakh phraseology, linguoculturology, cognitive and communicative linguistics.
