The interaction of first- and second-order motion signals at the local-motion-pooling level were investigated using locally-paired dots that moved orthogonally to each other. Dots were either luminance-defined, which could, potentially drive both first- and second-order local-motion units, or contrast-defined, which only drive second-order local-motion units. The response measure used was the nature of the motion percept: either unidirectional or transparent motion. The likelihood of perceiving...[Show more]
