摘要
N170是在面孔刺激呈现后170ms左右出现的脑电负成分.目前关于N170成分的研究主要争议集中在人的面孔识别是否具有特异性.本文通过对多篇相关文献的搜索、鉴别、分析,围绕人脸识别N170、视觉专家化理论、面孔特异性理论进行阐述,提出建立一个以刺激类型为自变量、N170波幅大小为因变量,个体对刺激的专家化水平为中介变量,刺激能利用的注意资源和测量选择的参考电极为调节变量的有调节的中介模型的设想,期望探讨诱发N170的内在机制.
Abstract
N170 is an EEG negative component recorded 130-200ms after stimulus presentation and peaks at 160-170ms.The N170 ERP has been found to be consistently larger in response to the presentation of faces than to other objects.In the meanwhile,study found that other non-facial stimulus such as charac-ters also could induce a large amplitude of N170.Thus the face specificity theory and visual expertise the-ory are born based on different findings of research.Currently,the main controversy of N170 on the specificity of human face processing is not addressed yet.We addressed this contradiction by analyzing multiple relate research,and proposed to establish a moderated-mediating model with stimulus type as the independent variable,N170 as the dependent variable,the individual's level of expertization of the stimu-lus as the mediating variable,and the attention resources that the stimulus could use and the reference electrode selected for measurement as the mediating variables,hopefully explore the internal mechanism of N170.
