The furrow illusion: Peripheral motion becomes aligned with stationary contours

S. Anstis
2012 Journal of Vision  
A spot moved vertically up and down across a background grating that was tilted at 458. In foveal vision this was seen accurately, but when viewed peripherally the spot's path was perceptually attracted toward the grating orientation, and at large eccentricities (.208) the spot appeared to move at 458, parallel to the grating. The intersections between the grating and the moving spot drive this illusion, revealing profound differences between fovea and periphery in processing visual motion.
