The basic categories for analysis and understanding of characteristics of the generational social-psychological space are specified with the aim to specify theoretical provisions of the concept of figural social-cultural relations of generations. The research goal was to develop and substantiate the theoretical foundation for cognition of generational expectations in the social-psychological space of coexistence. It is highlighted the influence of inter-generational psychological distances, social historical situation, and socio-cultural dimension on formation of certain types of expectations. There are represented the generational social positions (entelechy), actions-practices (habituated), and images, dispositions (habitus) as components of inter-generational expectations. In the context of the research on generations the entelechy (Aristotle's neologism) is used as a category which reflects social positions. There are presented the actions-practices which are transformed into habits, reactive stereotypes as habituated positions of generations – manifestations of expectations’ specificity. It is substantiated the use of the habitus concept (1) as a mentality outcome – the product of common generational mental activities which are fulfilled in dynamic constructing of experience and meanings; (2) as the schemes for information’ obtaining, emanation, combining, evaluating, classifying and using; (3) as the dispositional movements for construction of new figurations. In the theoretical constructing of inter-generational expectations it is specificated the generational institution concept as a phenomenon which fixes the newly created practices of generations; and the institutionalization concept as a form of social interactions in order to establish a possible order, relations within the limits of generational norms, rules, and morality. Thus, on the stage of determining the characteristics of social-psychological space of generations it is continued the scientific search for the ways of cognition of the peculiarities of inter-generation relations, mutual expectations of the generations of Children, Parents, and Grand-Parents.
