Fig. 4. Association of outcome-irrelevant learning and model-based control with compulsivity.
A Scatterplot showing the association between outcome-irrelevant learning and compulsivity. B Scatterplot showing the association between model-based control and compulsivity. C Posterior mean coefficients with 95% credible intervals taken from a Bayesian regression analysis exploring the effects of outcome-irrelevant learning and model-based control on compulsivity. Overall, the results show that outcome-irrelevant learning is positively related to compulsivity, even when controlling for the impact of model-based control (note that estimates are presented as standardized scores. Outcome-irrelevant learning estimates reflect the compound scores across five closely related task-based estimates, model-based control estimates reflect the compound scores across three closely related task-based estimates, and compulsivity reflects a factor that mainly loaded on self-report items of washing, checking, ordering, and grooming).
