摘　　要：目的:研究非临床社交焦虑个体的注意偏向,并比较词和面孔表情作为实验材料的敏感性。方法:被试26人,采用点探测任务,研究被试对不同类型刺激(威胁、快乐、中立)的注意偏向。结果:面孔表情任务中,高分组对威胁刺激反应时显著长于其它刺激,词语任务中差异不显著;低分组不存在偏向。结论:社交焦虑个体对威胁信息有回避倾向;面孔表情是区分社交焦虑注意偏向更有效的实验材料。This study examined the attentional bias in non-clinical social anxiety, and compared the sensitivity of words and facial expressions as stimuli. 26 subjects were required to execute a dot-probe task, which investigated the RT differences of the high social anxiety group （HSA） and the low social anxiety group （LSA）in response to different stimuli. The results found HSA tended to avoid threatening stimuli rather than happy and neutral stimuli. This trend was more significant when facial expressions were used as stimuli, an indication that facial expressions is a more sensitive index than words. No attentional bias was found in LSA.
