It is shown that the motivational component of formation of a picture of the world is characteristic for all stages of this process at teenagers. Other components are actualized in the course of formation of a picture of the world, being combined among themselves in various variations: formation of knowledge, search of values and sense, formation of individual strategy of behavior and studies, reflection, estimated processes and so forth. Stages of self-determination of the teenager are given in culture. World picture formation is a difficult cyclic process of interiorisation, resulting in the formation of teenager’s value and sense activity foundations, cognitive intellectual important believes, reasoning, feelings and practices based on the sociocultural norms and values, influencing the individual behavioral strategies and actions choice.
