【摘要】：情緒啟動和語義啟動的強弱快慢以及加工過程是獨立還是平行一直是研究者關(guān)注的熱點，而現(xiàn)有的研究大多是對兩種啟動進行間接對比，本研究使用經(jīng)過匹配的實驗材料和相同的實驗任務(wù)，結(jié)合ERP技術(shù)對情緒啟動和語義啟動做直接比較，，以期為現(xiàn)有的兩種啟動之間的比較給出更為直接和客觀的證據(jù)，并對它們之間的爭論做出一些解釋。 方法：采用經(jīng)過標準化匹配的實驗材料和“圖—詞”范式，設(shè)置SOA為250ms，實驗任務(wù)分別為情緒效價判斷任務(wù)和語義分類任務(wù)，使用事件相關(guān)電位技術(shù)對自動化加工水平下的情緒啟動和語義啟動之間的異同作比較研究。 結(jié)果：對行為結(jié)果的分析表明，在SOA=250ms時出現(xiàn)了典型的情緒啟動和語義啟動效應(yīng)，均表現(xiàn)為啟靶關(guān)系一致時促進對目標刺激的加工，啟靶關(guān)系不一致時阻礙對目標刺激的加工。LPC的潛伏期結(jié)果分析發(fā)現(xiàn)，啟靶關(guān)系主效應(yīng)顯著，F(xiàn) (1,18)=6.164，p 0.05，偏η2=0.256。相比于啟靶不一致關(guān)系(128.7ms)，啟靶一致時LPC的潛伏期更短(122.5ms)；將各條件與其相應(yīng)的基線條件進行配對樣本t檢驗，結(jié)果發(fā)現(xiàn)：在P4，P3，Pz點上，情緒啟動不一致條件的潛伏期顯著長于相應(yīng)的基線條件；在Pz點上，情緒啟動一致條件的潛伏期顯著短于相應(yīng)基線條件。Beta波分析結(jié)果表明，在目標刺激后200-300ms時間段內(nèi)，啟動類型與電極位置交互作用顯著，校正后F (4.20075.604)=2.671，p 0.05，偏η2=0.129；進一步t檢驗發(fā)現(xiàn)在F4電極位置處，相比于語義啟動，情緒啟動的能量增強（ERS）更大。除小波分析外，行為結(jié)果和腦電數(shù)據(jù)的分析均未見與任務(wù)有關(guān)的交互作用。 結(jié)論：1.在自動化加工水平上，在對信息的認知評價階段，人腦對情緒信息流更加敏感；2.在自動化加工水平上，情緒啟動和語義啟動的加工速度相同；3.在自動化加工水平上，情緒啟動和語義啟動是相對獨立的兩個過程。
[Abstract]:The speed of emotional priming and semantic priming and whether the processing process is independent or parallel has always been the focus of attention of researchers, but most of the existing studies are indirect comparison of the two kinds of priming. In this study, the matched experimental materials and the same task were used to directly compare emotional priming and semantic priming with ERP technology, in order to provide more direct and objective evidence for the comparison between the two kinds of priming. And make some explanation to the argument between them. Methods: using standardized matching experimental materials and "graph word" paradigm, the SOA was set to 250 ms.The experimental tasks were emotion titer judgment task and semantic classification task, respectively. Event-related potentials were used to compare the similarities and differences between emotional priming and semantic priming at automated processing level. Results: the analysis of behavioral results showed that there were typical emotional priming and semantic priming effects in SOA=250ms, both of which promoted the processing of target stimuli when the starting-target relationship was the same. The results of latency analysis of LPC, which hinders the processing of target stimulation when the relationship between the target and the target is inconsistent, shows that the main effect of the starting-target relationship is significant (F _ (1 / 18) 6.164 / p 0.05, 畏 _ (2) = 0.256). The incubation period of LPC is shorter (122.5ms) than that of 128.7ms, and it is found that at the point of P4 / P3 / Pz, each condition is matched with its corresponding baseline condition. The incubation period of emotional priming inconsistent condition was significantly longer than that of corresponding baseline condition, and at Pz, the latency of emotional priming consistent condition was significantly shorter than that of corresponding baseline condition. Beta wave analysis showed that, in the 200-300ms period after target stimulation, the latency of the condition was significantly shorter than that of the corresponding baseline condition. After correction, F (4.20075.604) 2.671 (p) 0.05, 畏 _ (2) (0.129). Further t test showed that the energy of emotional activation was greater than that of semantic priming at F4 electrode position. With the exception of wavelet analysis, there was no interaction between behavioral results and EEG data. Conclusion 1. At the level of automation, the human brain is more sensitive to the flow of emotional information in the cognitive evaluation of information. At the level of automation, the processing speed of emotional priming and semantic priming is the same as that of semantic priming. At the level of automation, emotional priming and semantic priming are two relatively independent processes.
