The concept of this manual is focused on the goals that face the course "Age Psychology." This course should not so much contribute to increasing the private scientific erudition of students studying in the specialty "Psychology," but to solve a number of interrelated methodological tasks: creation of a clear modern picture of development in ontogenesis (with clarification of its specific features, emphasis in the study of development mechanisms, identification of nodal moments in the system of theoretical concepts and empirical knowledge), formation of a special way of thinking (determined by the leading principles of Russian psychology, the modern type of scientific rationality, the modern understanding of the categories "development," "socialization," "growing up")This methodological manual is built as a guide to the sections of the course from the standpoint of Russian developmental psychology and illustrates the main provisions of the course program "Age Psychology" with excerpts from the works of classics of Russian psychology, as well as authoritative modern researchers in this area.
