Abstract
The velocity of apparent movement induced by a dynamic visual noise (DVN) version of the Pulfrich effect increases during tracking of the perceived moving textured plane, giving rise to a percept of visual acceleration. Recorded eye movements show consistent acceleration, with a maximum velocity ten times greater than that estimated during fixation of a stationary point superimposed upon the DVN. This gradual increase may be due to continual updating by the efferent copy of the oculomotor control signal that closes a positive-feedback loop. The component of the perceived velocity induced by the DVN is, however, independent of eye velocity, and thus the oculomotor unity negative-feedback control loop is functionally opened.
