Avoidance and safety behaviors are typically triggered by fear and adaptive to prevent aversive outcomes and harm to the individual. In anxiety and related disorders, these behaviors are, however, excessive, persistent, and related to irrational fears. Most importantly, these behaviors result in substantial impairments and costs for the individual (e.g., not being able to go out anymore). In this research project, we are investigating the role of avoidance costs for the development of fear and avoidance. Moreover, we examine how positive outcomes competing with threat and fear may facilitate fear-opponent action to overcome avoidance (e.g., incentive-based extinction of avoidance).
