A book for anyone seeking a compact introduction to the science of experience and behavior - from students to interested laypeople. Hans-Peter Nolting and Peter Paulus present a wide range of psychological knowledge concisely yet interconnected in various ways. This aims to foster two important competencies: structuring new psychological topics and applying psychological knowledge to practical cases. Through numerous examples, the authors explain many themes, questions, and solutions in psychology. In its 15th edition, the easily understandable and well-founded basic structure of the book remains unchanged; however, many examples and illustrations have been revised, and new topics such as media psychology and digitalization have been addressed.
