Brief Summary
The first aim of this study is to establish the role of maladaptive reliance on habits for impaired control in addiction, employing a novel task - the Action-Sequence-Task (AST), which assesses interference between habitual and goal-directed control. The AST, along with the developed computational model, will be employed to test whether participants with Alcohol Use Disorder (AUD) and control participants differ with respect to task performance and estimated model parameters. The investigators hypothesize stronger habitual behavior (increased habitual tendency) and an increased susceptibility to conflict between habitual and goal-directed control, measured as increased interference, are associated with AUD. The second aim of the study is to understand whether Pavlovian-to-Instrumental Transfer (PIT) reflects more of a controlled, goal-directed process, or a more automatic, habitual process. The investigators will use the single-lever PIT task as it is an efficient tool for testing the interaction between Pavlovian cues and instrumental behavior, especially when they are in conflict. In these trials, top-down control must be allocated to successfully overcome the conflict, which may share some common underlying mechanisms with the arbitration between goal-directed and habitual behavior during conflict, as assessed by the novel AST. The third aim of the study is to investigate whether severely dependent AUD patients would show a stronger PIT effect compared to a control group, consistent with the investigators' previous findings.

Outcome Measures
Primary Outcomes (2)
Behavioral single-lever Pavlovian to instrumental transfer (PIT) effect
Strength of interference PIT effect assessed with the single-lever PIT paradigm: increased error rate in the incongruent condition as compared with the congruent condition.
1 day, 1 hour
Action Sequence Task (AST) day one and day two
Habit formation: faster response time and decreased errors of preforming fixed compared to the random action sequence. Shift from goal-directed to habitual control: less choices of the high reward keys in trials in the incongruent trials where the goal-directed control and the habitual action sequence are in conflict (incongruent trials)
2 days, 1 hour per day
Secondary Outcomes (2)
Counting Stroop task
1 day, 10 minutes
Go-Nogo Simon task
1 day, 20 minutes
Study Arms (2)
Alcohol Use Disorder (AUD) Group
Participants with alcohol use disorder (moderate to severe if no withdrawal symptoms)
Control Group
Participants without SUD
Interventions
The paradigm consists of four parts: In the first part, an instrumental learning task is completed in which subjects must learn which stimuli require a response and which do not. In the second part, a classical (Pavlovian) conditioning task is then completed in which subjects learn by passive viewing which stimuli are associated with certain amounts of money. The third part measures to which instrumental responses (learned in Part 1) are modulated by the presentation of the classically conditioned stimuli (learned in Part 2). At the same time drug-associated stimuli are presented in the background measuring to which extent they conflict with the learned instrumental behavior. In the last part, query trials are implemented in which the participants have to choose between two pictures to assess the relative cue value.
Participants need to press four keys according to the cue location; two keys are associated with high reward, while the other two are associated with low reward in case of correct and timely responses. The explicit goal is to maximize the reward. While in half of the trials the cues are presented in a random order, in the other half of the trials, participants repeatedly perform a fixed action sequence of 12 elements (habit condition). The degree of action sequence chunking (i.e. automation) is assessed via the differences in error rates and reaction times between the random and fixed order condition (habit parameter). Importantly, 15% of all trials are dual- target trials. In these the goal-directed system (press high reward key) and the action sequence (press sequence key) can either be in line (congruent trials) or in conflict (incongruent trials) with each other, thus the interference between goal-directed and habitual control can be tested.
