This compact textbook introduces you to the psychological basics of human communication of everyday life in an entertaining way. You will encounter groundbreaking concepts, models, and axioms of communication (including well-known names such as Paul Watzlawick and Friedemann Schulz von Thun), different perspectives on communication, and various communication styles and patterns. You will learn what it means to communicate successfully and what makes successful communication difficult or even prevents it. And virtually in passing, you will learn to better understand your own communication and therefore yourself. This book is a translation of the original German 1^st edition Was wir uns wie sagen und zeigen by Ulf Lubienetzki, published by Springer-Verlag GmbH Deutschland, ein Teil von Springer Nature in 2020. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
