Alterations in neurobiological mechanisms associated with decision-making in individuals with Obsessive-Compulsive Disorder
Obsessive-Compulsive Disorder (OCD) has been defined as a disorder of decision-making. We aim to characterize the behavior of patients with OCD when they have to make decisions and characterize the neurobiological mechanisms during that process. Consequently, we will conduct a study in which patients with OCD and healthy controls will perform the Balloon Analogue Risk Task during functional magnetic resonance imaging. The Balloon Analogue Risk Task (BART) is a behavioral measure of decision-making that studies decision-making under ambiguity. In this task, participants can sequentially inflate a balloon or stop the play, earning money the more they inflate the balloon. When they inflate the balloon, this can either grow larger or explode (losing the money). The probability of explosion is higher the larger the balloon gets, without knowing the exact size at which the balloon will explode.
