<p>Habitual action is typically distinguished from goal-directed action by its insensitivity to changes in the reward value. There is an ongoing discussion whether this insensitivity is an intrinsic design feature of habits or, rather, a function of the cognitive system that controls habitual action tendencies. The proposed study investigates this issue using functional magnetic resonance imaging of brain activity before and after a reward devaluation in an outcome-selective Pavlovian-to-instrumental transfer (PIT) paradigm. Based on expected value of control theory, it is hypothesized that neural activity of the dorsal anterior cingulate cortex (dACC) is increased during presentations of Pavlovian cues associated with a devalued outcome. This neural activity is hypothesized to reflect increased control allocation to situations predictive of a devalued reward.</p>

No need for them to be recommenders of PCI Registered Reports. Please do not suggest reviewers for whom there might be a conflict of interest. Reviewers are not allowed to review preprints written by close colleagues (with whom they have published in the last four years, with whom they have received joint funding in the last four years, or with whom they are currently writing a manuscript, or submitting a grant proposal), or by family members, friends, or anyone for whom bias might affect the nature of the review - see the code of conduct
