Human goal-directed behavior is resistant to interventions on the action-outcome contingency

The paper tests how human goal-directed behavior responds to interventions disrupting action-outcome contingencies, finding that behavior remains sensitive to outcome value despite these interventions.

Distributed activity in the human posterior putamen distinguishes goal-directed from habitual control

The paper uses fMRI decoding to show that neural activity in the posterior putamen during learning predicts individual differences in habit versus goal-directed behavior across multiple cohorts.

Model-based and model-free valuation signals in the human brain vary markedly in their relationship to individual differences in human behavioral control

The paper examines how model-based and model-free valuation signals in the human brain relate to individual differences in behavioral control using fMRI data from a large sample.
