摘要: N170是在面孔刺激呈现后的130-200ms记录到的并在160~170ms时达到峰值的一种脑电负成分。目前, 在N170的研究中存在争议性的问题有:N170反映面孔结构编码还是面孔特征编码; N170是否是面孔特异性成分; 以及N170是否受注意的影响等。这些争议也为N170后续研究指明了方向, 即探讨结构编码和特征编码在诱发N170成分上起着怎样的作用; 比较不同熟悉度的刺激材料所诱发的N170反应差异; 探讨N170成分与识别电位间的关系;采用多研究方法的结合从不同层面深入揭示N170的认知机制。

Abstract: The N170 component is a negative brain potential, occurring at 130-200ms time windows, peaking around 160-170ms after stimulus (e.g. faces, object) onset, with a posterior lateral distribution. Recently, studies of N170 focus mainly on three questions: what cognitive mechanism N170 reflects, face structural or feature encoding; whether or not it is face-specific; or whether the component is affected by conscious awareness. In terms of the above questions, future research could investigate the effect of structural and feature encoding on N170 response, compare familiarities of different stimulus on N170, differentiate the N170 from recognition potential, and combine multiple methods to real the cognitive mechanism of N170.
