It's fair to say that communication is one of the relatively young sciences, since it only began to be considered as such (science) in the mid-twentieth century. But as a science, it belongs to both the humanities and the social sciences, since communication makes a contribution to various areas of social life, such as politics, health, citizenship and so on. In fact, a communication theorist once remarked on the "omnipresence" of communication, in the sense that it is present in different disciplines. In this sense, this book also addresses a particular field of communication, namely: Interpersonal communication. This field of communication is often considered a "hot potato" by many researchers. The reason: its complexity. This book takes a holistic approach to communication, covering its genesis, human issues, personality traits and transactional analysis.
