The article presents the theoretical approaches that reveal the role and importance of reflexive processes in the human inner world system. Starting points of the research, and its methodological grounds are defined. The nature of reflexive processes within the framework of structural and poly-processual paradigm is shown. View of the system of man's inner world is presented. The processes of its self-organization in terms of meta-system approach are described. The inner world systems are differentiated according to their tendency toward homeostatic or heterostatic existence. Aspects from the position of which it is possible to consider reflexive processes at the level of the internal world systems: content, quality and dynamics are identified. It is stated that the interaction of reflexive processes and inner world is subject to the principle of intersystem heterochrony.
