Eeg Features Of Explore-Exploit Decision-Making In Alcohol Use Disorder, Ethan Campbell

Psychology ETDs

Little research has assessed explore-exploit behavior in addiction using drug cues and even fewer studies have measured the neural activity underlying these behaviors. The present study aims to explore brain mechanisms of disordered decision-making in alcohol use disorder (AUD) through electroencephalography (EEG) during performance of a novelty bandit task with alcohol imagery and using a validated computational model of explore-exploit dynamics. Individuals with AUD (n = 28) and age and sex-matched controls (n = 27) showed differences in choice behavior and showed differences in EEG activity as a function of exploratory behavior, chosen stimulus type, and explore-exploit computational …

The Trauma, Substance Use, And Crime Connection: Characteristics And Recidivism Outcomes Of Adult Offenders, Kathryn F. Fokas

Despite exceptionally high rates of trauma and substance use among incarcerated offenders, treatments remain limited in scope and availability within the criminal justice system. Identifying shared underlying mechanisms and potential gender differences could facilitate the development of interventions to target the vicious cycle of trauma, substance use, and crime. This study aimed to test a novel conceptualization of trauma, substance use, and criminal history as a composite risk factor for recidivism, including posttraumatic world assumptions as a hypothesized mediator and gender as a potential moderator. Participants were adult offenders from a community corrections program. Due to many institutional barriers and …
