The scintillating grid illusion: influence of size, shape, and orientation of the luminance patches.

abstract：:Gori and Hamburger (2006, Perception 35 853-857) devised a new visual illusion of relative motion elicited by the observer's motion. We propose that the systematic error of direction discrimination found by Lorenceau et al (1993, Vision Research 33 1207 - 1217) can explain this illusion. The neural correlate of such a...
