Alterations in Functional Connectivity: Being Watched as an Indicator of State Anxiety

Abstract

Anxiety increases self-focused attention and rumination. Individuals with anxiety are sensitive to being watched by others, as being watched provokes self-referential processing and induces thoughts regarding others perceptions of oneself. However, whether the neural sensitivity to being watched depends on the level of anxiety remains unclear.We investigated the relationship between anxiety and the neural sensitivity to being watched by others.The anxiety of 25 healthy participants (mean age standard deviation, 23.08 1.71 years; 12 men and 13 women) was evaluated using the Spielberger StateTrait Anxiety Inventory. Resting state electroencephalography data was collected under the alone condition and the condition of being watched by another person. By subtracting the phase lag value between the two conditions, we determined the alterations in participants functional networks when they were being watched. We then found the correlation between the Spielberger StateTrait Anxiety Inventory scores and reactivity of functional connectivity when being watched.The score of state anxiety was significantly correlated with increased phase lag values in the left precuneus, bilateral caudal anterior cingulate cortex, and right rostral middle frontal cortex in the beta band (p< 0.05). We found no significant correlation between the trait anxiety scores and altered phase lag values.Functional connectivity may be involved in the default mode network relevant to self-referential processing and the dorsal attentional network. Our results suggest that self-focused mental processing and sensitivity to being watched by others could be common in people with anxiety, thus expanding the current understanding of the cognitive mechanisms behind anxiety.
