This study investigated the time-course of attentional bias in socially phobic (SP) and non-phobic (NP) adults. Participants viewed angry and happy faces paired with neutral faces (i.e., face-face pairs) and angry, happy and neutral faces paired with household objects (i.e., face-object pairs) for 5000ms. Eye movement (EM) was measured throughout to assess biases in early and sustained attention. Attentional bias occurred only for face-face pairs. SP adults were vigilant for angry faces relative to neutral faces in the first 500ms of the 5000ms exposure, relative to NP adults. SP adults were also vigilant for happy faces over 500ms, although there were no group-based differences in attention to happy-neutral face pairs. There were no group differences in attention to faces throughout the remainder of the exposure. Results suggest that social phobia is characterised by early vigilance for social cues with no bias in subsequent processing.
本研究调查了社交恐惧症（SP）和非社交恐惧症（NP）成年人注意偏向的时程。参与者观看了愤怒和快乐的面孔与中性面孔（即面孔-面孔配对）以及愤怒、快乐和中性面孔与家庭物品（即面孔-物体配对）配对 5000 毫秒。在整个过程中测量眼动（EM），以评估早期和持续注意力的偏差。注意偏向仅发生在面孔-面孔配对中。与 NP 成年人相比，SP 成年人在 5000 毫秒暴露的前 500 毫秒中对愤怒面孔比对中性面孔更加警觉。SP 成年人在 500ms 以上也对快乐面孔保持警觉，尽管在注意快乐-中性面孔对时，两组之间没有注意差异。在其余暴露时间内，两组在注意面孔方面没有差异。结果表明，社交恐惧症的特征是对社交线索的早期警觉，而后续处理则没有偏差。
