In the 1st FP, we established smartphone-based experiments in individuals with AUD and showed that inter-individual differences as well as intra-individual fluctuations in cognitive control and decision-making are associated with changes in drinking behavior. In the 2nd FP, based on a heuristic process model of self-control that specifies multiple pathways to a loss of control over drinking, we will investigate two mechanisms that may underlie intra-individual fluctuations in the mobilization of cognitive control: (i) an underestimation of the expected value of control and (ii) deficient error- and conflict-monitoring.
