摘要：

Two binocular cues to the direction of an object's motion in depth are the ratio (phi(R)/phi(L)) between the velocities of the object's retinal images in the right and left eyes and the ratio (phi/gamma) between the velocity of the binocularly-fused image of the object and the rate of change of disparity. We report that the apparent direction of motion in depth of a monocularly-camouflaged target can be varied by altering the ratio phi/gamma. Because no monocular motion signal is available in this case, we conclude that the ratio phi/gamma is a sufficient cue to the direction of motion in depth. This is not to deny that the phi(R)/phi(L) cue might be used in the everyday visual situation where monocular velocities phi(R) and phi(L) are available to the brain.
