“…In Experiment 3, where depth order should have been unambiguously provided by motion perspective, the addition of changing-size cues further improved vection. These findings sit well with the idea that changing-size and stereoscopic motion channels converge at the same motion-in-depth stage of the visual system (Regan & Beverley, 1979;Regan et al, 1979aRegan et al, , 1979b). …”

“…Regan and his colleagues have shown that changing disparity produces more effective motion-in-depth perception than does changing size for fast-moving objects observed for a reasonable period of time (e.g., 1 sec; Regan & Beverley, 1979). The reverse was found for briefly glimpsed, slow-moving objects.…”

“…Regan and his colleagues have argued that changingsize and stereoscopic motion stimuli generate signals that converge at the same "motion-in-depth stage" of the visual system (Regan & Beverley, 1979;Regan, Beverley, & Cynader, 1979a, 1979b. They showed that if a stimulus' changing-size and changing-disparity cues indicated opposite directions of motion in depth, it was possible to completely cancel the impression of motion in depth.…”

During self-motions, different patterns of optic flow are presented to the left and right eyes. Previous research has, however, focused mainly on the self-motion information contained in a single pattern of optic flow. The present experiments investigated the role that binocular disparity plays in the visual perception of self-motion, showing that the addition of stereoscopic cues to optic flow significantly improves forward linear vection in central vision. Improvements were also achieved by adding changingsize cues to sparse (but not dense) flow patterns. These findings showed that assumptions in the heading literature that stereoscopic cues facilitate self-motion only when the optic flow has ambiguous depth ordering do not apply to vection. Rather, it was concluded that both stereoscopic and changingsize cues provide additional motion-in-depth information that is used in perceiving self-motion.

The contribution of stereo vision to one-handed catching

Participants with normal (StereoN) and weak (StereoW) stereopsis caught tennis balls under monocular and binocular viewing at three different speed conditions. Monocular or binocular viewing did not affect catching performance in catchers with weak stereopsis, while the StereoN group caught more balls under binocular vision as compared with the monocular condition. These effects were more pronounced with increasing ball speed. Kinematic analysis of the catch partially corroborated these findings. These results indicate that StereoW catchers have not developed a compensatory strategy for information pick-up, and that negative effects of a lack of stereopsis grow larger as temporal constraints become more severe. These findings also support the notion that several monocular and/or binocular information sources can be used in the control of interceptive action.

Moreover, in extensive research determining the effects of selectively adapting these proposed channels, it has been found that these channels appear to fatigue over time with extended viewing and to recover with sufficient rest-very similar to the behavior of the cortical organizations hypothesized to underlie reversible figures.…”

The reported reversals of a rotating Necker cube, which changes direction of rotation when a perspective reversal occurs, were examined under a number of conditions. These permitted comparisons of reversal rates within viewing periods, across successive viewing periods within an experimental session, and across successive weekly sessions. In addition, observers viewed either one or two rotating cubes simultaneously within each of the various viewing periods. Clear evidence for a learning effect was obtained in the form of significant savings across successive viewing periods and sessions. At the same time, results from the multiple-cube conditions and from the pattern of reversals within individual viewing periods appeared to be more consistent with a process of neural fatigue. A two-stage model of reversible-figure perception is proposed which is characterized by (1) fatiguing with extended viewing of the two sets of neural channels that underlie the two percepts of the reversible figure, and (2) learning, which helps to establish the organization of the cortical channels as well as moderate channel activity via such processes as attention and strategy.In the last decade there has been a resurgence of theoretical and empirical activity related to a particular class of visual illusions most commonly referred to as reversible figures. This class of illusions includes such well-known figures as the Necker cube, Rubin's vase-faces, the Schroeder staircase, the Mach folded card, Fisher's man-girl, Boring's young girl-old woman, the Maltese cross, and several others (see Attneave, 1971, for examples of these and other reversible figures). Although empirical research with these figures can be traced back to the last century, there is still extensive interest in them because of the insights they are thought to provide into the nature of the perceptual process by their curious multistable character.Two competing classes of theories have evolved in an attempt to explain the perceptual fluctuations reported for the Necker cube and other reversiblefigure illusions. I The older theory, that of neural satiation (cf. Attneave, 1971;Howard, 1961;Kohler & Wallach, 1944;Orbach, Ehrlich, & Heath, 1963), proposes a passive process of fatigue as the basis for perceived reversals. In this view, the cortical organization underlying one perspective of a reversible figure satiates or fatigues with extended viewing. It then gives way to a second, fresher cortical organization underlying the other perspective. This
