摘　　要：目的:探讨情绪信息对不同知觉负载下视觉搜索绩效的影响。方法:采用字母搜索任务,调节目标字母的灰度来操纵知觉负载,进行3(情绪面孔:积极、中性和消极)×9(知觉负载:目标字母灰度RGB 0,0,0~RGB 80,80,80)的被试内实验设计,记录被试在不同条件下的字母搜索正确率和反应时。结果:(1)相对于高知觉负载,低知觉负载条件下的视觉搜索正确率更高,反应更快;(2)情绪效价与知觉负载的交互作用显著。在低知觉负载水平下,积极面孔条件下的视觉搜索正确率更低;高知觉负载水平下没有表现出情绪效价的影响作用。结论:知觉负载和情绪信息会共同影响视觉搜索绩效。低知觉负载条件下积极情绪分心物表现出干扰优势。Objective:The study aimed to explore the effect of emotional stimuli and perceptual load on the performance of visual search task.Methods:Using a within-subject experimental design,subjects were given a letter search task involving emotional stimuli(positive,neutral and negative faces)and nine levels of target letter grey(RGB O,0,O~RGB 80,80,80).The accuracy and RTs of subjects in letter search were recorded.Results:Subjects were faster and more accurate at searching target letter in the low-load condition than that in the high-load condition.At the same time,there was an interaction between emotion and load.In the low-load condition,subjects responded worse in visual search to positive faces condition than other emotional conditions and it showed the stronger interference effect.Conclusion:Perceptual load and emotional stimuli will jointly affect visual search.In the low-load condition,positive emotional stimuli show the advantage of interference.
