【摘要】：內(nèi)隱態(tài)度一直是社會(huì)神經(jīng)科學(xué)領(lǐng)域的研究熱點(diǎn)。對(duì)于種族面孔的內(nèi)隱態(tài)度,以往研究往往將其和種族面孔感知分類相混淆。本研究依據(jù)刻板印象激活的兩階段模型,運(yùn)用ERPs和行為技術(shù)來分離種族內(nèi)隱態(tài)度激活的兩個(gè)階段。 實(shí)驗(yàn)一運(yùn)用事件相關(guān)電位技術(shù)和簡(jiǎn)式內(nèi)隱聯(lián)想測(cè)驗(yàn)(brief-IAT)來考察亞洲黃種人對(duì)黑種人(1a)和白種人(1b)這兩個(gè)外族的內(nèi)隱種族態(tài)度。行為結(jié)果顯示了對(duì)黑種人相對(duì)消極的內(nèi)隱態(tài)度,和對(duì)白種人相對(duì)中性的態(tài)度。腦電結(jié)果證實(shí)了種族內(nèi)隱態(tài)度激活和社會(huì)類別激活的不同時(shí)程。在ERPs指標(biāo)上分別體現(xiàn)在N170和N270、LPP上。 基于實(shí)驗(yàn)一,實(shí)驗(yàn)二運(yùn)用情感啟動(dòng)范式,以黑種人和白種人面孔作為啟動(dòng),要求被試判斷隨后呈現(xiàn)的目標(biāo)詞匯的效價(jià)。SOA分別為30ms、150ms和400ms。行為數(shù)據(jù)上,SOA為150ms時(shí),黑人面孔促進(jìn)了對(duì)消極詞匯的反應(yīng),白人面孔促進(jìn)積極詞匯的反應(yīng)。在腦電上,一致性效應(yīng)表現(xiàn)在N400和LPP上。 主要結(jié)論： (1)本族黃種人對(duì)黑種人持消極的內(nèi)隱態(tài)度,對(duì)白種人的內(nèi)隱態(tài)度是中性的； (2)種族內(nèi)隱態(tài)度激活分為兩個(gè)階段：第一階段是對(duì)種族面孔的感知分類,表現(xiàn)在N170上,第二階段是在前一階段基礎(chǔ)上的態(tài)度激活,表現(xiàn)在N270、N400和LPP上。
[Abstract]:Implicit attitude has always been a hot topic in the field of social neuroscience. Previous studies often confuse the implicit attitude of racial faces with the classification of racial face perception. Based on the two-stage model of stereotype activation, ERPs and behavioral techniques were used to separate the two stages of ethnic implicit attitude activation. In experiment 1, we used event-related potential technique and simple implicit association test (brief-IAT) to investigate the implicit racial attitudes of Asian yellow people to black race (1a) and white race (1b). The behavioral results showed a relatively negative implicit attitude towards the black people and a relatively neutral attitude towards the Caucasians. EEG results confirmed the different stages of implicit attitude activation and social class activation. The index of ERPs was reflected on N170 and N270 LPP, respectively. Based on experiment 1, experiment 2 used affective priming paradigm, using black and white faces as the primer, and asked the subjects to judge the titer of the target words. The SOA was 30 Ms / 150 Ms and 400 Ms / s respectively. According to behavioral data, when SOA is 150ms, black faces promote the response to negative words, while white faces promote positive lexical responses. On EEG, the consistency effect was observed on N400 and LPP. The main conclusions are as follows: (1) the yellow race has a negative implicit attitude towards the black people and the implicit attitude towards the white people is neutral; (2) the activation of implicit attitude of race is divided into two stages: the first stage is the classification of racial faces, which is shown on N170, and the second stage is the activation of attitude on the basis of the previous stage, which is manifested on N270, N400 and LPP.
