WHAT IS A CRUCIAL DETERMINANT IN ANORTHOSCOPIC PERCEPTION

There are two important problems in anorthoscopic perception. The firs t is how a sequence of parts of a figure viewed through a slit is inte grated into a whole. The second is how the distortion of an anorthosco pic image along the direction of its motion occurs. To answer the ques tions, two experiments and two demonstrations were performed by concei ving compound figures of one horizontal and one curvilinear component and a method which permits seeing anorthoscopic and ordinary images at the same time. From the results, the idea of anorthoscopic motion com plementary to apparent motion is introduced as a crucial determinant t hat permits an integration of the parts into a perception of the whole . As regards the distortion of the percept we agree with Rock, et al.' s 1987 assumption but also consider that the distortion depends on the ratio of speed of anorthoscopic motion to real motion.
