【摘要】：采用事件相關(guān)電位技術(shù)和三類刺激的經(jīng)典oddball范式,以內(nèi)隱的方式探討外傾特質(zhì)個體的自我參照加工程度效應(yīng)及其神經(jīng)機制。實驗發(fā)現(xiàn),外傾被試的高自我相關(guān)名字在各個ERP成分上都比其他刺激誘發(fā)了更大波幅。在P2上,高自我相關(guān)的刺激比其他刺激誘發(fā)了更大的P2波幅和更長的P2潛伏期,其中中線腦區(qū)的效應(yīng)最大。在N2上,高自我相關(guān)的刺激比其他刺激誘發(fā)了更大的N2波幅和更短的N2潛伏期,其中額區(qū)位置的效應(yīng)最大�？刂平M被試的高自我相關(guān)名字比外傾型被試的高自我相關(guān)名字誘發(fā)了更大的N2的波幅和更短的N2潛伏期。在P3平均波幅上,高自我相關(guān)的刺激比其他刺激誘發(fā)了更大的P3波幅,其中中線效應(yīng)最大。對比外傾型被試,控制組被試的自我參照刺激誘發(fā)了更大的P3波幅。研究結(jié)果表明外傾特質(zhì)個體的自我參照加工具有程度效應(yīng),但對比控制組被試,外傾特質(zhì)個體的自我參照加工的程度效應(yīng)更弱。
[Abstract]:Using event-related potential technique and classical oddball paradigm of three types of stimuli, the effects of self-referential processing on extroverted individuals and their neural mechanisms were investigated in an implicit way. The extroverted subjects' high self-related names were more volatile in each ERP component than other stimuli. On P2, high self-correlation stimuli induced larger P2 amplitude and longer P2 latency than other stimuli. In N _ 2, high self-correlation stimuli induce greater N _ 2 wave amplitude and shorter N _ 2 latency than other stimuli. The position of frontal area was the most effective. The high self-correlation names of the control group induced a larger N _ 2 wave amplitude and a shorter N _ 2 latency than those of the extroverted subjects, and the mean amplitude of P3 was higher than that of the extroverted subjects. The high self-related stimuli induced greater P3 amplitude than other stimuli, in which the midline effect was the largest. The results showed that the self-referential processing of extroverted individuals had a degree effect, but compared with the control group, the control group had higher amplitude of P3. The degree effect of self-referential processing of extroverted individuals is weaker.
