The problems of professional socialization of young people and students become ever more topical now. Under the influence of the Internet and media, a youth request is formed to change educational and vocational guidance processes. Changes in professional socialization processes occur both at the level of socialization agents and at the level of socializing persons. The society strongly manifests the need to search and form modern models that provide predictable and orderly interaction within professional socialization. The theoretical-methodological basis of this article is a topological description based on graph theory, which allows determining the relationship between components of the model of professional socialization of youth at the level of concepts (constants). As a method of formalizing the structure, a cognitive model is used, defined in graph theory as a sign digraph. Analytical studies are based on a teaching model based on a double feedback loop. The essence of professional socialization is revealed at the intersection of processes such as adaptation and internalization, at implementation of basic education, professional education and social self-realization processes. The cognitive model is presented as a complex image, including a mental model and an adaptation model. Factor impact integration gives rise to a complex reaction of the professional socialization factor as a node of intersection of simple loops. The cognitive model is a structure for integrating causes and decomposing effects. It allows forming a unified and holistic view of the studied problem of professional socialization of young people and provides the targeted separation of significant knowledge about the situation of professional orientation in the media.
