The paper presents the findings of theoretical and empirical studies devoted to the development of the human “life model” construct, introduced to specify the concept of the life scenario and considered as its fragment in a particular area of life. The authors highlight that the life models are of a dynamic nature, being a process of individual self-fulfillment in different areas of life, determined by the individual’s activity in addressing the challenges of life. The study uses: (1) the authors’ questionnaire “Life Models”, empirically tested for three groups: youth, older generation, high school students; (2) automated semantic analysis of Internet resources and content analysis of online accounts of young people and older generation; (3) a set of techniques for personality assessment, including Big Five (T. Costa, R. McCrae), value orientations survey (Schwartz), self-efficacy questionnaire (J. Maddux, M. Scheer). A series of empirical studies (involving 2,281 respondents aged 19 to 55 from various Russian cities) described the variations of life models in the professional area, close relationships, and the area of self. The study indicates that they are based on traditions that meet the conservative perspective and on the trends of social changes, i.e., increasing demand for flexibility and mobility, increasing opportunities for education, development, and self-fulfillment. The combined effect is evident in the diversity of life models. Social transformation unevenly affects the life plan of young people, leaving some areas of life to be more conservative (the area of close relationships) and adapting other areas to the spirit of time (the professional area). The older generation serves as the source of preservation of traditions in youth’s building of the life scenario, while peers and the digital space contribute to its transformation. The study confirms the promising nature of the concept of life model as a unit of description of the multidimensional space of life of a modern person.
