Assigning the right credit to the wrong action: compulsivity in the general population is associated with augmented outcome-irrelevant value-based learning.
(Nature Research, 2021-11-05)Compulsive behavior is enacted under a belief that a specific act controls the likelihood of an undesired future event. Compulsive behaviors are widespread in the general population despite having no causal relationship ... -
Dopamine enhances model-free credit assignment through boosting of retrospective model-based inference.
(eLife, 2021-12-09)Dopamine is implicated in representing model-free (MF) reward prediction errors a as well as influencing model-based (MB) credit assignment and choice. Putative cooperative interactions between MB and MF systems include a ... -
Human subjects exploit a cognitive map for credit assignment.
(PNAS, 2021-01-26)An influential reinforcement learning framework proposes that behavior is jointly governed by model-free (MF) and model-based (MB) controllers. The former learns the values of actions directly from past encounters, and the ... -
Model based planners reflect on their model-free propensities.
(PLOS, 2021-01)Dual-reinforcement learning theory proposes behaviour is under the tutelage of a retrospective, value-caching, model-free (MF) system and a prospective-planning, model-based (MB), system. This architecture raises a question ...
