The book is devoted to an extremely important, but little-studied problem: how a child masters the space of the surrounding world and what traditional methods the children's subculture and folk pedagogy have created for this. The fourth edition of the book (previous ones were published in 1999, 2000, 2004) is supplemented with new illustrations and the chapter “Children's subculture in space and time.” How do lullabies contribute to the formation of the most important spatial concepts in a child? What and why is a child afraid at home and in an unfamiliar place? Why are children attracted to landfills? Why do children make “hides” and “secrets”, build “headquarters” and go to “scary places”? The originality of the approach and the amazing observation of the author help to understand the complexity and importance of personal tasks that a little person has to solve when exploring the world of adults and creating his own world. The novelty of scientific attitudes, the unusual nature of the problems discussed, the depth and thoroughness of its analysis make the publication of the next edition of this book a notable event for a wide range of specialists in psychological and pedagogical profiles, as well as for all those interested.
