ABSTRACT
Objective: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.
