摘　　要：目的探讨高特质焦虑个体对情绪面孔的注意偏向。方法被试20名大学生,采用改进的朝向和反向眼跳试验范式,研究高低焦虑个体对情绪和中性面孔条件下的注意偏向。结果朝向眼跳中,具有情绪意义的面孔相对于中性面孔会引起高特质焦虑个体更快更多的注意,并在认知加工过程中占有优先权。反向眼跳中,高特质焦虑个体对负性或者正性面孔的眼跳潜伏期相对于中性面孔而言更长,眼跳错误率更高。说明情绪图片被捕获,注意很难从情绪图片上解除,对其抑制比较困难。结论验证了高特质焦虑个体对情绪信息存在注意偏向,这与很多结论是一致的,并进一步证明了高特质焦虑个体的注意偏向是由注意定向加速和注意解除困难共同导致的。Objective To investigate the attentional bias towards emotional faces in individuals with high trait anxiety. Methods The improved paradigms of pro-saccade and anti-saccade were used to study the attentional bias of individuals with high or low trait anxiety towards the emotional and neural faces among 20 undergraduates. Results In the pro-saccade, the faces with emotional meanings attracted more and faster attention of individuals with high trait anxiety than the neutral faces and took precedence in the cognitive processing. In the anti-saccade, the saccade latency for negative or positive faces was longer and the error rate of saccade was higher than that for neutral faces in individuals with high trait anxiety. It was showed that once the emotional pictures were captured, the attention was difficult to be removed from those emotional pictures and be disengaged. Conclusion It is verified that individuals with high trait anxiety have attention bias to the emotional information, which is consistent with many conclusions. It is further proved that the attention bias of individuals with high trait anxiety is caused by the acceleration of attention orientation and the difficulty of attentional disengagement.
