根据陈霖的拓扑知觉理论,在视觉感知中,拓扑差异的检测要快于局部特征的检测.本研究组认为,这一现象可能是对有“洞”图形和无“洞”图形的感知差异所造成的.本文旨在检验这两类图形所存在的知觉差异究竟是什么.利用脑电(ERP)技术,测量“洞”和“非洞”图形所引起的视觉诱发电位(VEP),探究“洞”和“非洞”的区别.两类图形引起的VEP区别体现在N170上,“洞”图形的反转使得N170的潜伏期显著变化,而“非洞”图形的反转不会引起N170潜伏期的变化.人脸与非人脸物体的反转引起的N170变化与本结果相似.本研究认为,对“洞”的感知更偏向于整体加工,而对于“非洞”则更偏向于特征加工.
According to Chen Lin’s theory of topological perception, in the visual perception, the detection of topological differences is faster than the detection of local features.This group believes that this phenomenon may be a phenomenon of “hole” and “” Graphics caused by differences in perception.This paper aims to test these two types of graphics what is the difference between the perception of the use of electroencephalography (ERP) technology to measure the “hole” and “non-hole” graphics caused Visual evoked potential (VEP) to explore the difference between “hole” and “non-hole.” The difference between the VEPs caused by the two types of graphics is reflected in the N170 and the inversion of the “hole” pattern causes a significant change in the latency of N170 , While the reversal of “non-hole ” pattern will not change the latency of N170.N170 change caused by the reversal of face and non-face objects is similar to the result of this study.In this study, Perception is more biased toward the overall processing, while for the “non-hole” is more characteristic processing.
