Abstract: The subject of the research is individual chronotope as psychological basis for personality transformations occuring in the process of construction and projection of one's life path. The purpose of the research is to analyse chronotopic grounds for development of functionining of personality in terms of variety of directions (vectors) of life trajectories. Functions of individual chronotope are inclusion, fixation and preservation of new life meanings and attitudes to oneself, others and the world), particularities and features, forms and methods of interaction with their further actualisation in various life spheres. To achieve the research purpose, the author has used conceptual provisions of a number of approaches such as systems approach that reveals complex systems nature of such processes as formation, development and determinism; situation-based approach that describes the unity of external and internal realities of personality;and psychosocial approach that integrates principles of personality, subject, development and determinism. The scientific novelty of the research is caused by the fact that the author proves temporal and topological grounds for personality dynamics in terms of variety of life trajectories. The main conclusions are the following. As a result of the influence of external and internal factors, there can be three main vectors or variants of personality dynamics in the process of chronotope formation. These variants of personality dynamics reflect constructive, stagnating and destructive tendencies and these are ascending, constant and descending vectors. Deformation and distortion of individual chronotope are caused by the focus on unsolvable life problem or past event (past choice preference).
