Abstract

While fear learning is an adaptive behavior critical to our survival, excessive fear can markedly impair one’s ability to function and is a central characteristic of anxiety disorders. In this chapter, we review research detailing the neurobiological mechanisms underpinning fear learning and regulation. We draw on research in both animal models and humans, highlighting developmental research whenever possible. In the first section we review the brain systems that support fear acquisition through both direct experience and social learning. In the second section, we focus on the various means by which learned fears can be lessened, including extinction, cognitive regulation strategies, actively coping with fear, and persistently inhibiting fear through reconsolidation. This basic fear-learning model provides a neuroscientific framework for understanding the role of Pavlovian fear learning in anxiety disorders and suggests potential approaches for treatment.
