The primary purpose is the implementation of the interdisciplinary approach to understanding and the construction of integrative models of understanding literary texts. The interdisciplinary methodological paradigm of studying text understanding, based on the principles of various sciences facilitating the identification of the text understanding essence (cognitive, anthropocentric, dialogue, interdisciplinary principles) is rationalized and described. Methods of various sciences are used in complex: the hermeneutic method (hermeneutic philosophy, hermeneutic psychology), the pragmatic understanding method (pragmatics), the cognitive analysis, the inference method (cognitive linguistics), the discourse analysis method (discourse linguistics) and the modelling method. A literary text understanding integrative model is offered which can be applied during the analysis of various types of texts and their interpretation. The research proves that the interdisciplinary approach facilitates the development of an integrative multilevel model of text understanding, on each level of which, knowledge required to ensure understanding is characterized and disciplines are indicated.
