Behavior is often dichotomized into model-free and model-based systems1, 2. Model-free behavior prioritizes associations that have high value, regardless of the specific consequence or circumstance. In contrast, model-based behavior involves consider

Every day we are faced with a huge amount of new information. We can’t learn about everything, we have to select what to learn about. We have many systems that contribute to learning in different ways, allowing us to select the most relevant inform

Recently there has been a reckoning in the dopamine field. This has suggested that the dopamine prediction error may function as a teaching signal, without endowing preceding events with value. We studied the cognitive basis of intracranial self-stim

SummaryFor over two decades, midbrain dopamine was considered synonymous with the prediction error in temporal-difference reinforcement learning. Central to this proposal is the notion that reward-predictive stimuli become endowed with the scalar val
