Craik-O 'Brien-Cornsweet效应（COCE）是一种错觉，其中亮度不连续引起错觉亮度。一个假设的机制，为诱导的错觉亮度是，大脑皮层构建一个亮度感知边缘信息的横向“填充”过程。填充假说的一个要求是，错觉形成的能力将受到填充传播速度的限制。本文给出的三种方法的结果表明，在COCE光栅的情况下，亮度信息以约19度/s的固定速度传播穿过中心视场，并分别以155或205（+/-20）mm/s的速度传播穿过视觉区域V1或V2。(C)1998爱思唯尔科技有限公司版权所有。
The Craik-O'Brien-Cornsweet effect (COCE) is an illusion in which luminance discontinuities give rise to illusory brightness. One hypothesised mechanism for the induction of illusory brightness is that the cortex constructs a brightness percept from edge information by a lateral 'filling-in' process. A requirement for the filling-in hypothesis is that ability of the illusion to form would be limited by the speed of propagation of the filling-in. The results.presented here from three methods indicate that in the case of COCE gratings brightness information propagates at a fixed speed across the central visual field of about 19 degrees/s, and across visual areas V1 or V2 at 155 or 205 (+/- 20) mm/s, respectively.
