Postitive psychology emerged as a research field 15 years ago, but is based on older traditions and research programs within psychology. The talk will give an overview of the positive psychology movement and its main concepts, such as positive emotions, orientations to happiness, and character strengths (like humor and appreciation of excellence and beauty), and their relation to well-being and health. In addition, positive interventions, character training, and the application of positive psychology in schools and the workplace will be discussed.
