ELAN – Enjoying Life: The Anhedonic Spectrum

The ELAN study examines four specific components of reward processing (wanting, liking, effort, learning) on different levels. We use questionnaires, questions via smartphone, physiological data, and four experiments in the MRI. Our goal is to precisely characterize anhedonia (i.e. the loss or reduction of pleasure and interest) and hedonic well-being with regard to these components of reward processing. We therefore measured 70 young healthy adults varying on their trait hedonic level from anhedonic to very hedonic. In addition, we conducted two larger online survey studies on anhedonia and mental health.
