Definition of Social anxiety disorder

Social anxiety is an experience of fear, apprehension or worry regarding social situations and being evaluated by others. People vary in how often they experience anxiety in this way or in which kinds of situations. Anxiety about public speaking, performance, or interviews is common. Social anxiety can be related to shyness. The experience is commonly described as having physiological components (e.g. sweating, blushing), cognitive/perceptual components (e.g. belief that one may be judged negatively; looking for signs of disapproval) and behavioral components (e.g. avoiding a situation). Not all cases deal with fear of being judged negatively, as some cases have social anxiety without any specific reason. It can also be associated with Asperger syndrome.
