This student research project systematically evaluates both established and newly developed mood induction methods and investigates how experimentally induced mood states influence cognitive processes, particularly reward learning and decision-making. Students will formulate their own research questions, design and conduct experiments with healthy participants, and analyze behavioral and self-report data. The project is run at Charité – Universitätsmedizin Berlin, Klinik für Psychotherapie (Department of Psychiatry and Neuroscience), Campus Charité Mitte (CCM).
