本研究考察了广泛性社交恐惧症（GSPs）患者的注意偏差假说。假设社交恐惧症个体对与人际关系情境相关的威胁刺激表现出注意偏见。这个假设是用“面对人群”的范式来检验的。gsp和非焦虑控制组（NACs）在12张干扰照片中检测到愤怒、快乐、中性或厌恶的目标脸。结果表明，与NACs相比，gsp对中性人群中愤怒的面孔比快乐的面孔表现出更大的注意偏差。与中性的干扰物相比，快乐和愤怒的干扰物更能减缓gsp的表现；NACs对干扰物类型没有这种敏感性。最后，gsp在识别愤怒表情时比识别厌恶表情要快；NACs检测这两种类型的面孔的速度一样快。讨论了这些发现对社交恐惧症维持的影响。
The present study examines the attentional bias hypothesis for individuals with generalised social phobia (GSPs). Socially phobic individuals were hypothesised to exhibit attentional bias towards threat stimuli relevant to interpersonal situations. This hypothesis was tested using the face-in-the-crowd paradigm. GSPs and nonanxious controls (NACs) detected an angry, happy, neutral, or disgust target face in a crowd of 12 distracter photographs. Results indicated that, compared to NACs, GSPs exhibited greater attentional biases for angry than for happy faces in a neutral crowd. GSPs were more slowed down in their performance by happy and angry versus neutral distracters; NACs did not exhibit such sensitivity to distracter type. Finally, GSPs were faster in detecting anger than disgust expressions; NACs detected both types of faces equally quickly. Implications of these findings for the maintenance of social phobia are discussed.
