【摘要】：情绪能够影响个体的一系列认知活动。以往研究显示，相对于正性情绪，个体更偏向对负性情绪做出优先反应。本研究主要使用三种面部表情图片（高兴、生气和中性）作为实验材料，采用时序判断范式（temporal order judgment，TOJ），通过两个实验，系统考察了面部表情对时序知觉的影响，从而对负偏向理论进行检验。本实验中，一组（两张）表情图片或同时呈现，或以变化的时间间隔（stimulus onsetasynchronies，SOA）呈现（-100ms,-34ms,-17ms,17ms,34ms,100ms），要求被试对两张图片出现的时间顺序做出判断。实验一让被试只判断先呈现的表情图片的位置，而不需要关注图片的具体情绪，实验二则变换了反应方式，让被试判断先出现图片的情绪。实验一和二的结果一致发现，，在短时间间隔内，面部表情影响了时序知觉，而在长时间间隔内不受其影响；相对于中性情绪面部表情，个体更易判断带有情绪的面部表情先出现，而相对于消极情绪的表情，个体更易判断积极情绪的面部表情先出现。在本研究条件下，可以得出以下结论：面部表情对时序知觉具有显著影响，但不支持负偏向理论的观点。
[Abstract]:Emotions can affect a range of cognitive activities. Previous studies have shown that individuals are more likely to respond preferentially to negative emotions than to positive emotions. The influence of facial expression on temporal perception was systematically examined, and the negative bias theory was tested.
In this experiment, a group of (two) expression pictures were presented either at the same time or at different time intervals (SOA) (- 100ms, - 34ms, - 17ms, 17ms, 34ms, 100ms). The subjects were asked to judge the time sequence of the two pictures. The specific mood of the picture, the experiment two changed the way of reaction, so that the subjects could judge the mood of the picture first.
Experiments 1 and 2 consistently found that facial expressions affected temporal perception in a short time interval, but not in a long time interval; compared with neutral emotional facial expressions, individuals were more likely to judge facial expressions with emotions appeared first, while compared with negative emotional expressions, individuals were more likely to judge positive emotional faces. Expression first appears.
Under the conditions of this study, we can draw the following conclusions: Facial expressions have a significant impact on temporal perception, but do not support the negative bias theory.
