【摘要】：結(jié)合ERP技術(shù)、創(chuàng)傷電影范式和改進的工作記憶范式探討了認知分心的強度對創(chuàng)傷性信息加工的影響。結(jié)果發(fā)現(xiàn),(1)高負荷上的N2波幅顯著大于低負荷上的。(2)在低工作記憶負荷上,創(chuàng)傷負性圖引發(fā)的LPP波幅顯著大于創(chuàng)傷中性圖和無關(guān)中性圖;而在高工作記憶負荷上,三類圖片引發(fā)的LPP波之間差異不再顯著。(3)在創(chuàng)傷負性圖上高、低負荷工作記憶任務(wù)誘發(fā)的LPP波差異顯著,且高負荷條件下的LPP波幅顯著小于低負荷條件。結(jié)果表明,相比低認知控制,早期高認知控制對創(chuàng)傷性信息的調(diào)節(jié)更有效,支持了認知控制理論。
[Abstract]:Combined with ERP technology, trauma film paradigm and improved working memory paradigm, the effects of cognitive distractions on traumatic information processing were discussed. The results showed that: (1) the amplitude of N2 wave on high load was significantly higher than that on low load. (2) on low working memory load, the amplitude of LPP induced by trauma negative map was significantly larger than that of trauma neutral map and independent neutral map, but on high working memory load, the amplitude of LPP was significantly higher than that of trauma neutral map and independent neutral map on low working memory load. The difference of LPP waves induced by three kinds of images was no longer significant. (3) the LPP waves induced by low load working memory tasks were significantly different from those on trauma negative maps and the amplitude of LPP waves under high load condition was significantly lower than that under low load condition. The results show that early high cognitive control is more effective in regulating traumatic information than low cognitive control, which supports the theory of cognitive control.
