【摘要】：從過(guò)度投入理論與激活反彈理論對(duì)瓶頸理論的質(zhì)疑出發(fā),采用ERP技術(shù)檢驗(yàn)了情緒性注意瞬脫的加工過(guò)程及其神經(jīng)機(jī)制。行為結(jié)果顯示,以恐懼面孔為T(mén)1,中性場(chǎng)景圖片為T(mén)2,則恐懼面孔T1相對(duì)中性面孔T1顯著降低了中性T2的識(shí)別正確率,進(jìn)而誘發(fā)了情緒性注意瞬脫。ERP結(jié)果進(jìn)一步顯示,相較于中性面孔T1,恐懼面孔T1誘發(fā)的情緒加工影響了代表中樞加工資源的兩階段P3波幅,使得其始終高于代表標(biāo)準(zhǔn)注意瞬脫的中性面孔T1條件和代表非注意瞬脫的單任務(wù)基線(xiàn)條件。以上結(jié)果證明,情緒性注意瞬脫形成自情緒性T1加工所誘發(fā)的中樞資源過(guò)度投入,而非源自中樞資源瓶頸。
[Abstract]:Based on the theory of excessive input and the theory of activation rebound, the processing process and neural mechanism of emotional attention transients are tested by ERP technology. The behavioral results showed that when the fear face was T 1 and the neutral scene image was T 2, the recognition accuracy of the fear face T 1 was significantly lower than that of the neutral face T 1, which induced emotional attention transient. ERP results further showed that the fear face T 1 was significantly lower than that of the neutral face T 1. Compared with the neutral face T1, the emotional processing induced by fear face T1 affected the amplitude of P3, which represented the central processing resource. It is always higher than the neutral face T 1 condition representing standard attention transient and the single task baseline condition representing non attention transient. These results suggest that emotional attention transients were induced by emotional T1 processing, but not from central resource bottlenecks.
