Abstract
En 中文
Learned helplessness has been suggested as a mechanism through which anhedonia in depression is developed. It has been theorised that this stems from a generalised pessimistic prior belief about the probability of success when attempting to actively avoid negative outcomes, thereby resulting in apathy and reduced motivation. Yet, how such a prior may relate to depression and apathy is unknown. Here, we leveraged a novel method based on cognitive tasks and Bayesian modelling to extract a reliable generalised prior expressing the probability with which negative outcomes are expected to be actively avoidable.
