This successful textbook on the psychology of communication explains - here in English for the first time - how human communication works in a very understandable way. It begins with the explanation of central terms and the explanation of known communication models (e.g. the models according to Schulz von Thun, Watzlawick, Hargie and colleagues), then describes means of non-verbal and verbal communication and ends with a clear and structured summary of communication forms. Concrete fields of application, stumbling blocks (e.g. intercultural differences in communication), practical examples and digressions in the book round off what has been read and consolidate what has been learned. In addition, free learning materials are available on the Internet with which readers can test their knowledge acquisition.
