情绪面孔搜索的不对称性:基于预览搜索范式

Asymmetry of Searching for Emotional Faces:Based on Preview Search Paradigm

采用预览搜索范式,在两个实验中分别使用情绪面孔示意图与真人情绪面孔图作为刺激材料,系统地考察六种搜索任务条件下不同情绪面孔的搜索效率。结果发现:在两种实验材料中都存在显著的预览效应,验证了采用情绪面孔材料进行预览搜索任务时仍然可以获得显著的预览效应,为预览搜索中图形刺激的使用提供新了的证据和支持;实验1出现了显著的愤怒面孔优势效应,实验2却出现了显著的高兴面孔优势效应,在情绪面孔搜索中刺激的视觉特征是出现这种不同优势效应的主要原因。

Schematic emotional faces and real emotion faces were used as the stimulus materials in two experiments. Also those two experiments used the preview search paradigm to study the search efficiency of the different emotional faces through six search tasks. It was found that there was a significant preview effect in both of these materials, which proved that the significant preview effect can be obtained by using emotional face material and it provided new evidence for the use of the graphic stimulus in the preview search; Experiment 1 showed a significant negative emotional facial advantage, but experiment 2 showed a significant positive emotional facial advantage. The possible reason is that the visual features of the stimulus in the emotional face search are the main reason for this different dominant effect.
