本文以三种表情面孔为材料,运用事件相关电位(ERP)方法探讨表情线索在注意朝向中与注视转移发生的交互及两者如何共同影响观察者的反应。结果发现:(1)线索效应在三种表情面孔的两种SOA中都出现了;(2)SOA较长时,注视线索效应量间的显著差异出现在中性和恐惧面孔、高兴和恐惧面孔间;(3)面部表情的效应出现在了表情线索诱发的P1成分上;(4)目标诱发的P1和N1说明了注视线索效应的存在及与表情间的交互。结论:表情线索先对观察者的朝向反应产生影响,随后是注视线索及其与表情线索发生的交互。
In this paper, we use the three facial expressions as the material, and use event-related potentials (ERP) to explore how the clue cues interact with the fixation metastasis and how the two affect the viewer’s reaction together. The results showed that: (1) clues appeared in both SOA of the three facial expressions; (2) significant differences in gaze clues appeared in neutral and fear faces, happy and fear faces when SOA was longer (3) the effect of facial expression appears on the P1 component induced by expression cues; (4) P1 and N1 induced by the target indicate the existence of gaze clues and the interaction with the expression. CONCLUSIONS: Expression clues affect viewer orientation first, followed by gaze clues and their interaction with expression clues.
