Enhanced self-focused attention combined with reduced external focus of attention plays an important role in the maintenance of Social Anxiety Disorder (SAD). Changing the attentional focus is a core element in cognitive behavioral therapy and actual treatments use Virtual Reality (VR) for attentional training. However, no VR attentional training combining eye tracking based feedback of attentional processes with exposure to public speaking has been investigated yet. Therefore, within a randomized controlled study we investigated the effects of an attentional training during public speaking in VR and examined differential effects of an attentional focus on social stimuli of variable vs. invariant valence. Within a training intervention, highly socially anxious individuals were instructed to focus on virtual audience members either of different valence (e.g., interested, bored) or only positive valence , followed by eye tracking based feedback. Using subjective, physiological, and eye tracking measures, we assessed the pre-post effects on affective reactions, self-perception and attentional processes during public speaking and general Social Anxiety. Preliminary results indicate a significant improvement in anxiety and physical reactions during public speaking, with no significant differences between the groups. Our findings suggest that attentional training with eye tracking based feedback to enhance external focus on social stimuli can be successfully conducted in VR. Both training versions could show positive short-term effects in highly socially anxious individuals. Finally, the results of this study will be used to optimize an attentional training in VR for patients with Social Anxiety to subsequently reduce symptoms in the long-term.
