Detecting visual motion is computationally equivalent to detecting spatiotemporally oriented contours. The question addressed in this study is whether the illusory oriented contour in the space–space domain induces corresponding illusory motion perception. Two experiments were conducted. In experiment 1, the Café Wall pattern, which elicits a strong illusion of orientation (Café Wall illusion), was found to induce an illusion of motion when this pattern was converted to the space – time domain. The strength of the motion illusion depends on the mortar luminance and width, as for the Café Wall illusion. In experiment 2, the adaptation to this illusion of motion was found to induce a motion aftereffect in a static test, which indicates that a first-order-motion system contributes to the induction of the motion illusion. In fact, the motion-energy model was able to predict the strength of this motion aftereffect.

When rotating stripes or other periodic stimuli cross the retina at a critical rate, a reversal in the direction of motion of the stimuli is often seen. This illusion of motion perception was used to explore the roles of retinal and perceived motion in the generation of optokinetic nystagmus. Here we show that optokinetic nystagmus is disrupted during the perception of this illusion. Thus, when perceived and actual motion are in conflict, subjects fail to track the veridical movement. This observation suggests that the perception of motion can directly influence optokinetic nystagmus, even in the presence of a moving retinal image. A conflict in the neural representation of motion in different brain areas may explain these findings.

Global Activity

Activity in the human motion complex (hMT+/V5) is related to the perception of motion, be it either real surface motion or an illusion of motion such as apparent motion (AM) or motion aftereffect (MAE). It is a long-lasting debate whether illusory motion-related activations in hMT+ represent the motion itself or attention to it. We have asked whether hMT+ responses to MAEs are present when shifts in arousal are suppressed and attention is focused on concurrent motion versus nonmotion features. Significant enhancement of hMT+ activity was observed during MAEs when attention was focused either on concurrent spatial angle or color features. This observation was confirmed by direct comparison of adapting (MAE inducing) versus nonadapting conditions. In contrast, this effect was diminished when subjects had to report on concomitant speed changes of superimposed AM. The same finding was observed for concomitant orthogonal real motion (RM), suggesting that selective attention to concurrent illusory or real motion was interfering with the saliency of MAE signals in hMT+. We conclude that MAE-related changes in the global activity of hMT+ are present provided selective attention is not focused on an interfering feature such as concurrent motion. Accordingly, there is a genuine MAE-related motion signal in hMT+ that is neither explained by shifts in arousal nor by selective attention.

Input Model

The Marr—Ullman model for motion detection in the human visual system functions by means of the dual input of polarity-specific edge detectors and luminance change detectors. Moulden and Begg (1986) found a polarity-specific motion aftereffect which they claimed provided support for this dual input model. The logic of their experiment is examined, and it is shown that several additional predictions arise from the Marr—Ullman model, which were not supported by Moulden and Begg's study. A more powerful experiment was carried out and these additional predictions were disconfirmed, although the polarity-specific effect did emerge. A consideration of alternative explanations of this effect led to a second experiment in which an attempt was made to discover the actual determinants of the effect. This revealed that polarity-specific units are unlikely to play any part in the phenomenon. It was concluded, in the light of this and other evidence, that one of a class of alternative models is more likely to be the actual mechanism for motion perception. However, careful consideration of the Marr—Ullman model indicated that it may be untestable in principle if various differentially weighted levels of neural integration are envisaged.

The aftereffect of motion is one of the oldest known illusions. It refers to the illusory motion of a stationary scene after some time of adaptation to real motion. While it is still unknown whether this adaptation effect has any functional value, it surely has served well as a tool to investigate the functional organization of the visual system. In this chapter some of the classic findings are discussed. More recent work using complex stimuli, attentional modulation, higher order motion, as well as modern neuro-imaging techniques has provided vision scientists with surprising new insights. Discussion of the related concepts of motion perception, motion transparency, and interocular transfer are included.

Several studies have examined the effects of auditory stimuli on visual perception. In studies of cross-modal correspondences, auditory pitch has been shown to modulate visual motion perception. In particular, low-reliability visual motion stimuli tend to be affected by metaphorically or physically congruent or incongruent sounds. In the present study, we examined the modulatory effects of auditory pitch on visual perception of motion trajectory for visual inputs of varying reliability. Our results indicated that an auditory pitch implying the illusory motion toward the outside of the visual field-modulated perceived motion trajectory. In contrast, auditory pitch implying the illusory motion toward the central visual field did not affect the perception of motion trajectory. This asymmetrical effect of auditory stimuli occurred depending on the reliability of the visual input. Moreover, sounds that corresponded in terms of their pitch-elevation mapping altered the perception of the trajectory of visual motion when apparent motion could be perceived smoothly. Therefore, the present results demonstrate that auditory stimuli modulate visual motion perception especially when smooth motion is perceived in the peripheral visual field.
