Abstract:

身段表情是情感神经科学里相对较新的话题。与面部表情相似，身段表情不可能孤立地呈现。以往研究表明，声音、演讲词、场景以及其他身段表情都会影响身段表情的加工。采用身段–场景的复合刺激，本研究选用记忆范式旨在探查不同认知任务下，场景如何对身段表情产生影响。结果显示，情感判断任务中，背景的再认率优于情绪识别任务中背景的再认率；情绪性背景的再认率高于中性背景的再认率；情绪识别任务中身段表情的再认率优于情感判断任务中身段表情的再认率。这可能表明认知任务不同，个体对背景和身段表情的注意模式不同。
Body expression is a relatively novel topic. Similar to facial expression, body expression is not likely to be an isolated object. Previous studies have shown that voice, linguistic label, scene or other body posture all influence emotion perception. Using compound stimuli of body and scene, we investigated how the scenes influence the processing of body expression in different cognitive tasks. The result showed that, recognition performance of scene was higher in affective judgment than that in emotion categorization; recognition performance of emotional scene was higher than that of neutral scene regardless of task type; recognition performance of body expression was lower in affective judgment than that in emotion categorization. This may suggest that different cognitive tasks influence attention pattern.
