【摘要】：本研究采用视觉搜索和意外再认记忆任务,结合事件相关电位技术,考察知觉负载对负性分心面孔的知觉加工和记忆的影响。在视觉搜索任务中,行为上恐惧分心面孔在高负载下干扰任务。ERP结果上,恐惧比中性分心面孔诱发更大的N170和N250;在低负载下恐惧比中性分心面孔诱发更大的N700,在高负载下没有差异。在意外再认记忆中,个体对低负载下的恐惧分心面孔表现出记忆。这些结果说明负性分心物在早期是自动化加工;晚期加工受知觉负载的调节,负载越低对负性分心物的过滤越少,存在对负性分心物的记忆偏向。
[Abstract]:In this study, the effects of perceptual load on the perceptual processing and memory of negative distracted faces were investigated by means of visual search and accidental recognition and memory tasks, combined with event-related potentials. In visual search tasks, fear of distraction in behavior faces interferes with task. ERP results under high loads, Fear induced more N170 and N250 than neutral distraction faces, while fear induced more N700 under low load than neutral distraction faces, but there was no difference under high load. In accidental recognition memory, individuals exhibit memories of fear, distractions and faces under low load. These results suggest that negative distractions are automated in the early stage, and that the later processing is regulated by perceptual load, the lower the load is, the less the filtering of negative distractions is, and the memory bias of negative distractions exists.
