摘要目的:探讨不同社交焦虑水平大学生在加工不同情绪面孔时注意偏向的行为和眼动特点。方法:根据Liebowitz社交焦虑量表得分筛选高、低社交焦虑大学生26人和27人，通过点探测任务测量被试在一致和不一致条件下的反应时和正确率，同时记录被试在观察愤怒、厌恶和中性面孔时的眼动特征。采用SPSS 19.0软件进行重复测量方差分析。结果:高社交焦虑组在面孔一致和不一致条件下的正确率分别为(0.97±0.10)和(0.93±0.15)；高社交焦虑组在一致和不一致条件下的反应时分别为(660.97±125.38)ms和(687.81±150.90)ms，高社交焦虑被试对靶刺激判断的正确率和反应时在不同一致性条件下的差异具有统计学意义[正确率： F(1，51)＝15.25， P<0.01；反应时： F(1，51)＝7.85， P<0.01]，低社交焦虑大学生的正确率和反应时不受一致性条件影响(均 P>0.05)。高、低社交焦虑大学生对情绪面孔的首次注视潜伏期和对中性面孔的首次注视潜伏期差异具有统计学意义[ F(2，102)＝15.01， P<0.01]；高、低社交焦虑大学生对情绪面孔的总注视次数与对中性面孔的总注视次数差异具有统计学意义[ F(2，102)＝4.38， P<0.05]。 结论:不同社交焦虑水平的大学生均表现出对情绪面孔的早期注意警觉和注意脱离困难，但只有高社交焦虑者在行为水平上表现出对情绪面孔的注意偏向。

abstractsObjective:To explore the behavior and eye movement characteristics when processing different emotional faces in college students with different levels of social anxiety.Methods:According to the scores of Liebowitz social anxiety scale, 26 and 27 subjects with high and low social anxiety were selected.The response time and accuracy of the subjects under consistent and inconsistent conditions were measured by the dot probe task.Eye movement data of the subjects were recorded when they viewed angry, disgusting and neutral faces.SPSS 19.0 software was used for repeated measurement analysis of variance.Results:The accuracy rates of the high social anxiety group were (0.97±0.10) and (0.93±0.15) under consistent and inconsistent conditions, and the response time of the high social anxiety group were (660.97±125.38) ms and (687.81±150.90) ms under consistent and inconsistent conditions.High social anxiety subjects showed significant differences in the accuracy and response time under different consistency conditions ( F(1, 51)=15.25, P<0.01 for accuracy, F(1, 51)=7.85, P<0.01 for reaction time), while low social anxiety subjects showed no significant difference(both P>0.05). There were significant differences between the first fixation latency for emotional faces and neutral faces( F(2, 102)=15.01, P<0.01). The total fixation time of emotional face and neutral face was significantly different ( F(2, 102)=4.38, P<0.05). Conclusion:College students with different levels of social anxiety all showed early attentional alertness and attentional disengagement difficulty to emotional faces, but only those with high social anxiety showed attentional bias to emotional faces at the behavioral level.
