The first monograph on transactional analysis, which has become a classic text and therefore the main source for the direction. The book contains the entire slender theory of E. Bern, and not only its main blocks deployed in subsequent publications - an analysis of script games - but also aspects that the author does not state in his other books. Therefore, experts turn primarily to this text, revolutionary in many respects and far from immediately assessed by professional psychologists. Designed for psychologists and psychotherapists.
