The aim of this research project was to elucidate the visual processing theoretically and experimentally which produces 3D visual illusion. In this term, I conducted experiments on the multiple wallpaper illusion, namely "subjective staircase", and proposed an explanation of the illusion. The conclusions derived from the results of the experiments were as follows :(1) when one fixates binocularly on an inclined sheet of paper upon which are drawn equally spaced dots, an apparent 3D staircse is perceived.(2) the height of apparent step was sucessfully described in terms of mathematics which describes the clssical wallpaper illusion.(3) the treads of apparent step were also successfully described in terms of the nearest-neighbor rule.(4) when the stimulus distance from an observer was varied while the proximal stimulus was constant, the critical angle of the stimulus inclination for the illusion was a function of the stimulus distance ; the critical angle decrease with an increase of the stimulus distance.(5) the subjective staircase illusion is a multiple wallpaper illusion.(6) the nearest-neighbor rule and the vertical horopter inclination explain successfully the illusion.

本课题旨在从理论上和实验上阐明产生三维视错觉的视觉加工过程。在这学期，我对多重墙纸错觉即“主观楼梯”进行了实验，并提出了错觉的解释。从实验结果中得出如下结论：(1)当一个人用双眼盯着一张倾斜的纸，纸上画着等距的点，就会感觉到一个明显的三维楼梯。(2)用数学方法成功地描述了典型墙纸错觉的视台阶高度。(3)用最近邻规则成功地描述了视步长的步长。(4)当刺激距离变化而近端刺激不变时，刺激的倾斜角临界值是刺激距离的函数；临界角随刺激距离的增加而减小。(5)主观楼梯错觉是多重墙纸错觉。(6)最近邻规则和垂直直升机倾角成功地解释了这种错觉。
