本研究采用情绪启动范式考察社交焦虑个体对正性刺激解释偏差。研究以正性和打碎的面孔为启动项，正性或负性非社交词为目标项，要求高社交焦虑组被试和控制组被试判断目标项的情感色彩，并记录其反应时与准确率。结果发现，两组被试具有不同的情绪启动模式：高焦虑组被试未表现出显著地相容性效应；他们在正性一正性条件下的反应时显著慢于控制组被试。研究结果提示高社交焦虑个体具有对正性社交刺激的解释偏差，他们不能充分理解正性社交刺激的积极含义。

Previous research suggestss that high social anxiety individuals may form biased interpretations of positive facial stimuli. It is suggested that social anxiety individuals may discount the positive social information, or even interpret it in a negative fashion. This bi- ased interpretation processing might tremendously influence social anxiety＇s positive affect in a negative way, as well as their quality of life. So it is important to learn more about social anxiety＇s cognitive processing of positive social information. Recently, some researchers focused on how social anxiety individuals process positive social information. However, most of these studies used self- report as their experimental method, and may suffer from several methodological limitations. The present study aimed to explore whether social anxiety is characterized by an interpretative bias towards positive facial stimuli using a more objective and accurate method. The affective priming paradigm developed by Fazio, Sanbonmatsu, Powel, ＆Kardes （1986） was applied as a measure of socially anxious individuals＇ biased interpretative pattern towards positive faces. And in the present study, the emotional faces were used as the primes, while the positive and negative words were used as targets. The current study consisted of a 2 （prime valence ： positivevs, scrambled faces） x 2 （ target valence ： positive vs. negative words） x 2 （ group type ： highvs, low social anxiety group） mixed factorial design. Only the group type was a between - subjects factor. In each trial, a fixation was first presented for 500 ms, followed by a positive or a scrambled face for 200 ms. After the face disappeared, there was an interval of 50 ms, during which a grey screen appeared before a positive or a negative word was presented. This word remained on screen for 2000 ms or until the participants pressed the reaction key. There was al000 ms interval between trials. Participants were asked to evaluate and categorize the affectively polarized non - social word targets. And they were instructed to focus on the task, and try to respond to the target words as quickly and as accurately as possible. Their reaction time and correctness were recorded, while only the reaction time was analyzed with the repeated measures ANOVA. After the prime task, participants were asked to evaluate the attractiveness of 10 neutral faces which were used to make the scrambled faces. Then, they were going to finish the Social Phobia Scale, and a questionnaire for personal information. After this, the participants were debriefed. The study found that the high social anxiety group and the control group exhibited different affective priming effects when primed by positive faces ： In high social anxiety group, no affective priming was found; while the control group showed the typical congruency effect for positive facial primes. They reacted significantly faster to the positive targets than those negative words. In addition, the social anxi- ety group took significantly longer time to respond to the positive target words than the controls. The results might suggest that social anxious individuals have an interpretation bias towards positive faces. They may make less positive interpretations on positive social in- formation. At the same time, the study showed that the affective priming paradigm can be successfully applied to test the positive cogni- tive bias in social anxiety group.
