Nothing to lose? Neural correlates of decision, anticipation, and feedback in the balloon analog risk task.

Understanding the subprocesses of risky decision making is a prerequisite for understanding (dys-)functional decisions. For the present fMRI study, we designed a novel variant of the balloon-analog-risk task (BART) that measures three phases: decision making, reward anticipation, and feedback processing. Twenty-nine healthy young adults completed the BART.

Feedback-Related Brain Potentials Indicate the Influence of Craving on Decision-Making in Patients with Alcohol Use Disorder: An Experimental Study.

Introduction: Alcohol craving is a key symptom of alcohol use disorder (AUD) and a significant cause of poor treatment outcome and frequent relapse. Craving is supposed to impair executive functions by modulating reward salience and decision-making.

Objective: The present study sought to clarify this modulation by scrutinizing reward feedback processing in an experimental decision-making task, which was accomplished by AUD patients in 2 conditions, in the context of induced alcohol craving and in neutral context.

Therapeutic success in relapse prevention in alcohol use disorder: the role of treatment motivation and drinking-related treatment goals.

Changing addictive behavior is a complex process with high demands on motivation. The Transtheoretical Model of Behavior Change provides a theoretical framework for explaining and predicting behavioral change, although its predictive value for addiction is somewhat inconsistent. The aim of the present study is to extend the Transtheoretical Model of Behavior Change by investigating not only treatment motivation but also the predictive value of the type of drinking-related treatment goal.

Decision- and feedback-related brain potentials reveal risk processing mechanisms in patients with alcohol use disorder.

Individuals with alcohol use disorder (AUD) are aware of the risks of alcohol abuse yet continue risky drinking. Research indicates that dysfunctional decision processes and trait variables such as impulsivity contribute to this awareness-behavior discrepancy. The present study focused on decision-related versus feedback-related processes as potential contributors to decision making in AUD by examining the relationship between decision choices and decision- and feedback-related ERP phenomena in the balloon analogue risk task (BART).
