Learning from others' experience: Social fear conditioning deficits in patients with severe alcohol use disorder

Résumé

Alcohol use disorder (AUD) is a significant public health problem. A better understanding of the psychosocial factors contributing to AUD is important for developing public health policy. The purpose of this study was to identify social mechanisms involved in AUD and, more specifically, to determine whether vicarious learning deficits are related to the disorder. A secondary objective was to evaluate the role of empathy in social fear conditioning.MethodsPatients with severe AUD (n = 30) and healthy participants (n = 30) performed a social fear learning (SFL) task. The task assesses how an association between a stimulus and an aversive consequence is acquired through social means. Specifically, participants observed a person receiving an electric shock (unconditioned stimulus; US) that was associated (conditioned stimulus; CS+) or not (CS−) with a neutral CS. The skin conductance response was used to measure the effect of learning.ResultsIndividuals with severe AUD showed a deficit in SFL, indicating that they had difficulty learning from another's negative experience. Patients also evaluated the emotional experience as less unpleasant than healthy participants.ConclusionsThis study is the first to show that patients with severe AUD have social learning deficits. The findings suggest that these individuals do not learn from another's negative experience. At a fundamental level, the findings demonstrate the importance of understanding the role of social mechanisms in AUD. At a clinical level, the study highlights the potential for using social learning enhancement to prevent relapse in individuals with severe AUD.
