Readaptation and resocialization are two factors in changing human behavior in the direction of greater social adaptation. These changes occur throughout life in a specific legal field. A person's position in the legal field is the third external determinant of his changed behavior. Social adaptation does not exist outside the legal field and is determined primarily by it. That is why the processes of readaptation and resocialization are primarily the field of legal psychology, at least from the point of view of its subject, which is proposed in this book.
