選取高厭惡敏感性和低厭惡敏感性個體作為本實驗的研究對象,運用ERP技術考察觀看厭惡、中性情緒圖片時,不同厭惡敏感性個體注意加工時程差異。結果發現,從早期波開始,相比低厭惡敏感性個體,高厭惡敏感性個體N1、N2波的波幅都增強,但到了晚期波,高低厭惡敏感性個體注意厭惡情緒圖片差異不顯著,但高厭惡個體注意中性圖片的LPP波顯著增強。這表明高厭惡敏感性個體不僅對高厭惡圖片有高注意,對中性情緒圖片也表現出較多注意。

In order to investigate the time-course difference of the attention that paid by high disgust sensitivity and low disgust sensitivity individuals when prcessing disgust emotional pictures and neutral emotional pictures, the presents study used the event-related potentials(ERPs) technique to study the difference of attention processing when they see. The results showed: For the N1, N2, high disgust sensitivity group was larger than low disgust sensitivity group. For the LPP, there was no significant difference between sensitivity groups for disgust pictures, but there was a significant difference between sensitivity groups for neutral pictures. These results suggest that high disgust sensitivity individuals shows higher attention to all stimulants. And as to the attention degree of neutral stimulant, high disgust sensitivity objects is still significantly higher than low disgust sensitivity objects.
