The introduction into psychology explores new developments, methodical extensions and current trends in psychology. Based on the guidelines of the DGPs, all relevant basics and areas of applications, as well as fields of activities for Bachelor and Master students and those, who are practising, are being introduced. Renowned scientists are demonstrating the status of research using current findings and are explaining the approaches of the respective sub-disciplines. Examples are utilised to illustrate applications in actual cases and food for thought at the end of each chapter is to encourage a more in-depth consideration.
