Blushing is associated with a heightened self-focused attention. In our study we are interested if this self-focused attention can be shown experimentally and if it can be changed by therapy and training. For the experimental part of the study, we want to compare blushing fearful individuals to social anxious participants who are not fearful of blushing and to healthy controls who report to blush either seldom or quite often. In the therapeutical part of our study, we compare an attention training to the standard cognitive behavioral therapy for social anxiety disorder in an intensive group therapy approach.
