- Abstract
- This article aimed to describe typical event-related potentials (ERP) components of emotional processing in patients with anxiety disorder and highly anxious individuals. ERP components associated with emotional processing could be broadly divided into three components with short, middle and long, respectively. Many studies show that patients with anxiety disorders are characterized by different emotional bias to specific stimuli and more sensitive to emotional stimuli than normal individuals. In addition, these emotional biases were stronger and quicker in patients with anxiety disorder than normal individuals. Some studies reported that anxious people show abnormality at the initial stage (e.g. P1) of emotional processing. However, other studies reported the abnormality at the late stage (e.g. LPP) or wholeness of emotional processing in anxious individuals. We summarized the updated finding of possible ERP components of emotional processing in patients with anxiety disorder and highly anxious individuals. The significance and clinical implication were discussed.
