Study on the sensory properties of “Rotating snake” illusion and contrast sensitivity of peripheral vision

Abstract

Specific design patterns produce motion perception in spite of still images. The “Rotating snakes” is a representative example of these motion illusions and it is grouped into the optimized Fraser-Wilcox illusion. The purpose of this study is to clarify the mechanism of the “Rotating snakes.” This study examines a relationship among retinal eccentricity, contrast sensitivity function, and perception of the illusory motion.
