The purpose of this research is to test a computerized intervention for people with co-occurring social anxiety and alcohol dependence. The intervention seeks to reduce symptoms by shifting attention away from alcohol-relevant and/or socially threatening cues. The investigators expect that participants receiving alcohol or anxiety training will experience reductions in those specific symptoms compared to participants in a control condition. The investigators also expect that participants receiving combined alcohol and anxiety training will show the largest reductions in alcohol and anxiety symptoms, relative to participants in any other condition.
