Abstract
Limited-lifetime Gabor stimuli were used to assess both first- and second-o rder motion in peripheral vision. Both first- and second-order motion mecha nisms were present at a 20-deg eccentricity Second-order motion, unlike fir st-order, exhibits a bias for centrifugal motion, suggesting a role for the second-order mechanism in optic flow processing.
