知觉与行为的分离在视错觉研究中的验证

知觉与行为的分离是指人的视觉对物体的知觉与对行为的控制属于两个不同的系统。最早人们从临床病例中发现存在知觉与行为的分离，以后Aglioti等利用铁钦纳错觉实验证实正常人中也存在这一分离现象。一些研究者将两者的分离看作是两个不同视觉皮层通路（腹侧知觉系统和背侧视觉运动系统）的结果。围绕这一分离现象的实验和假说引发了不少的争论。该文回顾了十年来利用错觉实验所做的众多验证性研究，分析了支持和否定分离现象存在的各类证据，对一些重要结果和观点进行了总结，并由此提出了自己的看法。

Verification of the Dissociation between Perception and Action in the Visual Illusion Experiments

The dissociation between perception and action refers to the phenomena that visual perception and visual control of action correspond to the two different systems. The dissociation was found from clinical cases at first. Aglioti and others verified the dissociation in normal people using Titchener circles illusion later. Some researchers looked on the dissociation as functions of two different cortical pathways (ventral stream vs. dorsal stream). There were lots of controversies on experiments and hypotheses about the phenomena. The article reviewed a lot of verification experiments done with illusion experiments last ten years, analyzed and summarized some important results and viewpoints, and hereby put forward ourselves opinion.
