Influence of Individual Traits on Adaptation Processes in Individuals With Alcohol Use Disorder

Alcohol Use Disorder (AUD) is a chronic condition that affects behavior, decision-making, and the ability to adapt to changing situations. While many studies have examined AUD from medical and social perspectives, less is known about how individual psychological traits influence the way people with AUD respond to uncertainty and adapt their behavior. This study aims to better understand how personal characteristics such as anxiety, self-esteem, sensitivity to reward and punishment, perfectionism, and cognitive abilities may influence adaptation processes in individuals with AUD. Participants receiving usual care at Paul Brousse Hospital will be invited to take part in a single experimental session lasting about 45 minutes. During this session, they will complete: * A computerized learning task in which they respond to visual stimuli and receive feedback on their performance * Standardized questionnaires assessing psychological traits and cognitive functioning The learning task is designed to evaluate how participants adjust their behavior when the rules of the task change unexpectedly. Researchers will measure how performance changes in response to uncertainty and examine how these changes relate to individual psychological characteristics. This research does not modify participants' medical care and involves no medication or invasive procedures. By improving understanding of the cognitive and behavioral mechanisms involved in Alcohol Use Disorder, the study may help advance scientific knowledge about how individuals adapt to uncertainty and inform future research in addiction and mental health.
