种族内隐态度的ERP研究
发布时间：2018-11-06 15:54
【摘要】：内隐态度一直是社会神经科学领域的研究热点。对于种族面孔的内隐态度,以往研究往往将其和种族面孔感知分类相混淆。本研究依据刻板印象激活的两阶段模型,运用ERPs和行为技术来分离种族内隐态度激活的两个阶段。 实验一运用事件相关电位技术和简式内隐联想测验(brief-IAT)来考察亚洲黄种人对黑种人(1a)和白种人(1b)这两个外族的内隐种族态度。行为结果显示了对黑种人相对消极的内隐态度,和对白种人相对中性的态度。脑电结果证实了种族内隐态度激活和社会类别激活的不同时程。在ERPs指标上分别体现在N170和N270、LPP上。 基于实验一,实验二运用情感启动范式,以黑种人和白种人面孔作为启动,要求被试判断随后呈现的目标词汇的效价。SOA分别为30ms、150ms和400ms。行为数据上,SOA为150ms时,黑人面孔促进了对消极词汇的反应,白人面孔促进积极词汇的反应。在脑电上,一致性效应表现在N400和LPP上。 主要结论： (1)本族黄种人对黑种人持消极的内隐态度,对白种人的内隐态度是中性的； (2)种族内隐态度激活分为两个阶段：第一阶段是对种族面孔的感知分类,表现在N170上,第二阶段是在前一阶段基础上的态度激活,表现在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.
