虽然从威胁性刺激中注意力脱离受损被认为会增强社交焦虑，但尚不清楚何时受损的脱离准确发生。本研究采用间隙任务（实验1）和重叠任务（实验2），考察了社交焦虑者和非寻求治疗的大学生对愤怒面孔的注意脱离障碍。高社交焦虑人群（实验1和实验2中N = 17）和低社交焦虑人群（实验1中N = 17，实验2中N = 19）被要求注视屏幕中心呈现的愤怒或中性面孔。然后，他们辨别周围目标刺激。实验1中，当面孔和目标之间存在时间间隔时，所有被试对愤怒面孔和中性面孔的反应时没有差异。然而，当没有间隙，脸继续出现在实验2（重叠任务），在高社交焦虑的人愤怒的面孔的RT比那些中性面孔的呈现时间为300毫秒或更长。在低社交焦虑的人中，愤怒和中性面孔的RT没有差异。这些结果表明，高社交焦虑的人在识别出愤怒的面孔后，很难将注意力从愤怒的面孔上分离出来。(C)2010爱思唯尔有限公司版权所有。
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. (C) 2010 Elsevier Ltd. All rights reserved.
