Understanding Aberrant Learning With Bayesian Modeling in Stimulant Use Disorder

      Compulsivity describes a person’s failure to stop an ongoing behavior that becomes maladaptive. Such failure may be due to a lack prefrontal inhibitory control, but it may also result from difficulties to identify or act upon negative feedback. In my talk, I will present evidence of altered feedback processing in patients with stimulant use disorder (SUD) and demonstrate how computational modeling approaches may help to elucidate pharmacological modulation of the processes hypothesized to underlie compulsive behavior.
