当两张相似的图片，重叠但稍微移位，交替投影在屏幕上时，可以看到明显的运动。连续的图像要有多相似才能给出明显的运动？这就是“对应问题”。操纵图片之间的局部和全局对应关系包括运动现象，如反向明显的运动;一个四冲程振荡周期，使一个方向上的连续运动的错觉;边缘定义的纹理，立体深度，或闪烁，动力学边缘;和波动。得出的结论是，人类的运动感知可能包括两个独立的机制。图片之间的局部逐点相关性是由一个相对外围的系统检测到的，可能是基于方向选择性神经单元。更微妙的全局对应关系由一个更具认知性的系统进行分析，该系统在处理运动之前提取边缘。
When two similar pictures, overlapping but slightly displaced, were projected on a screen in alternation, apparent movement could be seen. How similar must successive pictures be to give apparent movement? This is the ‘correspondence problem ’. Manipulations of the local and global correspondences between pictures included motion phenomena such as reversed apparent movement; a four-stroke oscillatory cycle which gave an illusion of continuous motion in one direction; edges defined by texture, stereoscopic depth, or flicker, kinetic edges; and wave motion. It was concluded that human motion perception may comprise two separate mechanisms. Local point-by-point correlations between pictures are detected by a relatively peripheral system, probably based on directionally selective neural units. More subtle global correspondences are analysed by a more cognitive system which extracts edges before it processes motion.
