| Abstract: | Anxiety can impair the central executive functioning in working memory (WM). Further, the adverse effect of anxiety on the central executive would be greater when threat-related distractors are present. This study investigated the effect of task-irrelevant emotional faces on WM updating in social anxiety. Forty-one socially anxious (SA) and thirty-nine non-anxious (NA) participants completed an emotional face interference n-back task coupled with eye movement recording. The results showed that, in the 2-back task, SA participants had longer reaction times in the angry-neutral and neutral-neutral interference conditions than in the no-interference condition, whereas NA participants had longer reaction times in the happy-neutral and neutral-neutral interference conditions than in the no-interference condition. In addition, SA participants initially fixated on angry faces more frequently and spent more time looking at them, whereas NA participants initially fixated on happy faces more frequently and spent more time looking at them. This study suggests that attentional bias towards social threats reduces the efficiency rather than effectiveness of WM updating in social anxiety. Moreover, SA individuals are better at resisting interference from task-irrelevant positive stimuli, while NA individuals are better at resisting interference from task-irrelevant threatening stimuli.
