Decision‑making infexibility in a reversal learning task is associated with severity of problem gambling symptoms but not with a diagnosis of substance use disorder

Decisions made by individuals with disordered gambling are markedly infexible. However, whether anomalies in learning from feedback are gambling-specifc, or extend beyond gambling contexts, remains an open question. More generally, addictive disorders—including gambling disorder—have been proposed to be facilitated by individual diferences in feedback-driven decision-making infexibility, which has been studied in the lab with the Probabilistic Reversal Learning Task (PRLT).
