This study aims to create and test new tasks that measure specific thinking, motivation, and decision-making behaviors in people with and without alcohol use disorder. Researchers want to use a special type of MRI scan called 7T MRI to see how these tasks affect brain activity. The goal is to develop reliable tasks that can be used in future studies to better understand how alcohol use disorders impact the brain and behavior. This study is looking for up to 400 participants, aged 18 to 65, who are either healthy volunteers or inpatients with alcohol dependence. Success for this study means developing tasks that consistently measure these behaviors and show related brain activity.

Study design

This interventional study plans to enroll up to 400 participants. It involves developing and testing tasks both outside and inside a scanner.

Compensation

Not stated in the trial record.

Follow-up

The primary outcome of developing and examining tasks is measured on an ongoing basis.
