Interattribute apparent motion.

Examined the relative strength of visual motion (SVM) for 5 stimulus attributes (color, luminance, texture, relative motion, and stereopsis), using 3 experienced psychophysical observers (aged 21-39 yrs). When 2 stimuli were defined by the same attribute, motion was visible for all visual attributes examined. SVM, as measured by the maximum displacement over which the motion could be seen between the alternating disks, varied by a factor of less than 2 as a function of the attribute defining the disks. Motion was also seen between 2 disks that were defined by different attributes, indicating that the motion process must have access to an integrated representation in which stimulus definition is not relevant.
