【摘要】：本研究采用視覺搜索和意外再認(rèn)記憶任務(wù),結(jié)合事件相關(guān)電位技術(shù),考察知覺負(fù)載對(duì)負(fù)性分心面孔的知覺加工和記憶的影響。在視覺搜索任務(wù)中,行為上恐懼分心面孔在高負(fù)載下干擾任務(wù)。ERP結(jié)果上,恐懼比中性分心面孔誘發(fā)更大的N170和N250;在低負(fù)載下恐懼比中性分心面孔誘發(fā)更大的N700,在高負(fù)載下沒有差異。在意外再認(rèn)記憶中,個(gè)體對(duì)低負(fù)載下的恐懼分心面孔表現(xiàn)出記憶。這些結(jié)果說明負(fù)性分心物在早期是自動(dòng)化加工;晚期加工受知覺負(fù)載的調(diào)節(jié),負(fù)載越低對(duì)負(fù)性分心物的過濾越少,存在對(duì)負(fù)性分心物的記憶偏向。
[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.
