The time course of attentional disengagement from angry faces in social anxiety

Abstract

While impaired attentional disengagement from threatening stimuli is thought to enhance social anxiety, it is unclear when the impaired disengagement occurs accurately. We used a gap task (Experiment 1) and an overlap task (Experiment 2) to reveal the impaired attentional disengagement from angry faces in socially anxious people with non-treatment seeking undergraduates. High (N = 17 in Experiments 1 and 2) and low socially anxious people (N = 17 in Experiment 1 and 19 in Experiment 2) were asked to fixate on an angry or neutral face presented at the center of a screen. Then, they discriminated the peripheral target stimuli. When there was a temporal gap between the face and target in Experiment 1 (gap task), the reaction times (RTs) for angry and neutral faces did not differ for all participants. However, when there was no gap and the face continued to appear in Experiment 2 (overlap task), the RTs for angry faces in high socially anxious people were longer than those for neutral faces after presentation times of 300 ms or longer. In low socially anxious people, the RTs following the angry and neutral faces did not differ. These results suggest that high socially anxious people face difficulty in disengaging attention from angry faces after recognizing them.

Barking up the wrong tree in attentional bias modification? Comparing the sensitivity of four tasks to attentional biases

“…Error bars represent the standard error of the mean. threatening stimuli, or the inability to disengage from them is debated (Amir, Elias, Klumpp, & Przeworski, 2003;Fox et al, 2000;Moriya & Tanno, 2011;Staugaard, 2010) and the intriguing temporal dynamics that the attentional blink task reveals, may allow for more nuanced assessment of how attentional biases unfold over time than the snapshot measurements other paradigms provide. By developing more diverse assessment methods of dysfunctional attention, theories of the role of attention in the development and maintenance of anxiety disorders can be fine-tuned, potentially yielding more effective treatment.…”

Reduced Processing of Facial and Postural Cues in Social Anxiety: Insights from Electrophysiology

“…This task requires participants to process a new item of information while already dealing with a first one and consequently to share visual processing resources [66]. It is therefore a measure of cognitive flexibility integrating several attentional components and notably attentional shift and re-engagement [13]. We could have postulated that anxious participants allocated reduced resources to cues processing to better focus on targets.…”
