Evidence for parallel processing in motion perception.
It is proposed that motion perception is mediated within two parallel channels in the visual system. These channels are distinguished by the following properties: rate of recovery from adaptation; degree of fine tuning for contour orientation; inclusion of color sensitive units; and ocular dominance characteristics. Three experiments are reported which test the hypothesized systems.
