Enhanced motion during gradual changes in luminance polarity

  • Stuart Anstis Department of Psychology, UC San Diego, La Jolla, CA, USA
Keywords: motion, reverse-phi, peripheral vision


A pattern that gradually reverses its polarity as it moves can appear to move farther and faster than it really does. I shall call this new effect ‘enhanced motion’, since it accentuates the amplitude and briskness of motion as opposed to reverse phi, in which polarity changes reverse the perceived direction of a moving object.
