The Effects of HD-tDCS on Cognitive Bias Among Individuals With Social Anxiety Symptoms

To examine the offline effects of high-definition tDCS (HD-tDCS) on attention, interpretation and memory biases in youth with social anxiety.

In current study, we adopted a comparative intervention study with randomized controlled in which we delivered multiple courses of offline anodal HD-tDCS over the left DLPFC. The aim of this study was to explore the offline impact of HD-tDCS on cognitive bias (including attention, interpretation and memory bias) among youth with social anxiety symptoms. In addition, the researchers sought to further investigate the impact of tDCS stimulation on social anxiety. We hypothesized that anodal tDCS would activates the left DLPFC to facilitate cognitive control of threat-related information among youth with social anxiety, thereby reducing threat attention, interpretation and memory bias, and even improving social anxiety symptoms.
