Anxiety is part of life. Speaking in front of a class, peering down from a ladder, or waiting to play in a big game might make any one of us feel nervous. Anxiety may even cause us to avoid talking or making eye contact—“shyness,” we call it. Fortunately for most of us, our uneasiness is not intense and persistent. Some of us, however, are more prone to notice and remember information perceived as threatening (Mitte, 2008). When the brain’s danger-detection system becomes hyperactive, we are at greater risk for an anxiety disorder, or for two other disorders that involve anxiety: obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD).1
