摘要：

目的:考察不同步的词汇背景对面孔情绪识别的影响。方法:以28名健康大学生为被试,采用情绪启动范式,设置五种不同的SOA条件(250 ms、100 ms、0 ms、-100 ms、-250 ms),启动刺激除了情绪词,还采用中性词作为控制条件,要求被试对目标情绪面孔做情绪类型判断。结果:在SOA为100 ms、0 ms和-100 ms时,均出现了词汇背景和面孔的显著的情绪一致性效应;其他两种SOA条件下没有出现该效应。当SOA为100 ms时,词汇背景对面孔情绪识别的影响主要表现为相同情绪价的词汇背景对面孔情绪识别的促进效应;而当SOA为0 ms和-100 ms时,词汇背景的影响主要表现为不同情绪价的词汇背景对面孔情绪识别的阻碍效应。结论:面孔情绪的识别受到了不同步的语言背景的影响,这种影响局限在一定的时间范围内,而且不同时间条件下影响的内在机制不同。

Objective: To investigate the influence of word context on emotion recognition from facial expression.Methods: 28 healthy college students participated in the experiment. The affective priming paradigm was adopted, with 5different SOAs, i.e., 250 ms, 100 ms, 0 ms, -100 ms and -250 ms. The prime stimuli were composed of not only emotion -al words, but also neutral ones as control conditions. Subjects were asked to identify the emotional categorization of targetfaces. Results: When the SOA was 100 ms, 0 ms and -100 ms, significant emotional congruency effects were obtained,while no such effect appeared in the other two SOA conditions. When the SOA was 100 ms, the emotional congruency effect was mainly driven by the facilitation effect to the target faces exerted by word context with the same emotional va -lence. While, the SOA was 0 ms and -100 ms, the emotional congruency effect was mainly driven by the inhibition effectto the target faces by word context with the different emotional valence. Conclusion: There is obvious influence of asyn -chronously presented word context on emotion recognition of facial expression. However, such effect is subject to time win -dow constraint, and the mechanism underlying the effect varies with different time window.
