The paper shows that dopamine release in the nucleus accumbens during instrumental learning reflects Bayesian inference of probabilistic beliefs about hidden environmental states.

This paper uses artificial neural networks to estimate parameters and identify cognitive models without likelihood computation, demonstrating effectiveness for models with inter-trial dependencies.

This study links age-related prefrontal glutamate levels to working memory deficits and decision-making impairments in older adults.

This study shows that human reinforcement learning is slower and less accurate for general choice types compared to concrete motor actions, due to credit assignment interference and slower information integration.
