Abstract: The experiment adopted the independent present paradigm to show positive and negative valence facial expression pictures to explore the differences between the recognition of positive and negative valence facial expressions pictures. The presentation time and the position of cue-target were controlled, and the eye-tracker was used to record the indexes of eye movement in the identification process. Results were as follows: 1)On the recognition speed and accuracy rate part, positive facial expression pictures′ processing exceeded the processing of negative facial expressions pictures, which showed the positive expression advantage. 2)The presentation time did not change the difference between the processing of positive and negative valence facial expressions pictures.3)There was a position effect of cues that cues around the mouth would contribute to the facial expression recognition. 4)The facial expression recognition followed the “eye-to-mouth-to-eye” principle. The consequence suggests that the processing mechanism of different facial expression is different; the effect is less in the depth of processing than the hint position.

摘要： 为探讨正负效价面部表情图片识别的差异,采用独立呈现范式呈现正负效价面部表情图片,控制呈现时间和提示线索位置,并利用眼动仪记录识别过程中的眼动指标。结果发现：（1）在识别速度和正确率上,加工积极面部表情图片高于加工消极面部表情图片,显示出积极表情优势。（2）呈现时间没有改变正负效价表情图片加工之间的差异。（3）存在提示线索位置效应,即提示线索在嘴部有利于面部表情识别。（4）面部表情识别遵循“眼部-嘴部-眼部”的规律。结果提示不同性质面部表情的加工机制不同,加工深度作用小于线索作用。
