Mood as a vehicle of reinforcement learning

The science of learning and decision-making has largely evolved in isolation from the study of emotions and moods. Yet both fields, I will argue, investigate the same core mechanisms: the fundamental computations of reinforcement learning. By explicitly linking these computations to emotions and moods, we not only gain new leverage to explain real-world behavior but also refine our models to better reflect how humans actually learn and plan. I will illustrate these advances through a large-scale, intensive longitudinal study using a bespoke mobile platform with wearable EEG. The results reveal mood as a vehicle of reinforcement learning and enable mood prediction up to five days in advance. This framework opens new paths for understanding how reinforcement learning functions adaptively, or goes awry.
