The interdisciplinary study is devoted to the elucidation of the author's concept of the deed integral, developmentally enriched and dialogically directed empathic interaction of a psychologist with clients of different ages, gender, mental experience, social status and mental organization of the individual self. The proposed concept was created, on the one hand, through a reflexive reconstruction of the content of the psychological theory of empathy known in Ukraine and abroad (L.P. Zhuravlyova, 2007), when it is step-by-step achieved, scenario-worked out and practically realized, mutual complementation of the developmental functioning of various types, levels and stages of the empathic process, resources, channels and means of empathic attitudes-relationships and individual psychological features of empathy of each participant in dialogic contact in the "psychologist-client" system, on the other hand - due to the use of the latest methodological optics of post-non-classical rationality, namely the author's cyclical-action approach with its basic principles (cyclicity, synergy, action, metasystem), a number of regularities and norms of cognitive thinking activity. Moreover, the universal tool for implementing research consciousness into life, which establishes the epistemological core of the concept advocated here, is a m e n t a l s c h e m e built according to the principle of quaternity in the context of the broad intellectual possibilities of the innovative sphere of professional methodologization (A.V. Furman, 2005, 2016). The starting idea in this case was the axiomatic statement that the process cycle of the current course of empathy is a separate, original act on the part of the individual. Taking into account the goal, task and subject field of this study, it is proved that: firstly, the most effective technology of collaborative psycho-spiritual filling of interpersonal relationships is modular-developmental interaction, which is first subject to a reflexive-action scripting, and then to a full-fledged existential implementation; secondly, the stages of deployment of personified empathic interaction can not only be justified on the basis of dominant processes (affective, cognitive, conative), but also more methodologically justified on the basis of the logic-canonical structure of the act (situation, motivation, action, afteraction); thirdly, the empathic dialogic cycle is best consciously organized by a practical psychologist while working with a client as a four-periodized and step-by-step (procedural) detailed act of personal empathy, which includes the alternating dominance of natural, affective-cognitive, conative-active and reflective types of empathy; fourthly, the psychologist's practical use of the action-reflective thinking scheme of the scenario confirmed the empirical effectiveness in his individual work with students of secondary and higher education, in particular with those who have special needs or are characterized by problematic behavior.
