“…Soto-Faraco, Lyons, Gazzaniga, Spence, and Kingstone (2002) reported that visual motion captured the direction of auditory motion when their onsets were synchronized, but not when visual motion was presented as lagging 500 msec behind the auditory motion. Sanabria, Soto-Faraco, Chan, and Spence (2004) extended the previous findings. They demonstrated that when the onsets of visual and auditory motion were consistent, visual motion could capture the direction of auditory motion, irrespective of the offset asynchronies.…”

In representational momentum (RM), the final position of a moving target is mislocalized in the direction of motion. Here, the effect of a concurrent sound on visual RM was demonstrated. A visual stimulus moved horizontally and disappeared at unpredictable positions. A complex tone without any motion cues was presented continuously from the beginning of the visual motion. As compared with a silent condition, the RM magnitude increased when the sound lasted longer than and decreased when it did not last as long as the visual motion. However, the RM was unchanged when a brief complex tone was presented before or after the target disappeared (Experiment 2) or when the onset of the long-lasting sound was not synchronized with that of the visual motion (Experiments 3 and 4). These findings suggest that visual motion representation can be modulated by a sound if the visual motion information is firmly associated with the auditory information.

“…Those results did not correspond to findings that attentional resolution is higher in the lower than in the upper visual field (He, Cavanagh, & Intriligator, 1996). Other recent studies that have used an audiovisual apparent-motion display have also demonstrated that the modulation of crossmodal integration by visual grouping is preattentive (Sanabria, Soto-Faraco, Chan, & Spence, 2004;Vroomen & de Gelder, 2000).…”

Occluded motion alters event perception

We employed audiovisual stream/bounce displays, in which two moving objects with crossing trajectories are more likely to be perceived as bouncing off, rather than streaming through, each other when a brief sound is presented at the coincidence of the two objects. However, Kawachi and Gyoba (Perception 35:1289-1294, 2006b) reported that the presence of an additional moving object near the two objects altered the perception of a bouncing event to that of a streaming event. In this study, we extended this finding and examined whether alteration of the event perception could be induced by the visual context, such as by occluded object motion near the stream/bounce display. The results demonstrated that even when the sound was presented, the continuous occluded motion strongly biased observers' percepts toward the streaming percept during a short occlusion interval (approximately 100 ms). In contrast, when the continuous occluded motion was disrupted by introducing a spatiotemporal gap in the motion trajectory or by removing occlusion cues such as deletion/accretion, the bias toward the streaming percept declined. Thus, we suggest that a representation of object motion generated under a limited occlusion interval interferes with audiovisual event perception.

“…Also, a combination of spatial and temporal factors has been shown to affect audiovisual judgments of phenomenal causality on the basis of the saliency of the constituent perceptual events (i.e., without strict audiovisual synchrony being required; Guski & Troje, 2003). Common motion and other Gestalt grouping principles have also been shown to facilitate crossmodal binding (Lyons et al, 2006;Sanabria et al, 2004;SotoFaraco, Kingstone, & Spence, 2003;Spence et al, 2007;Vroomen & de Gelder, 2000).…”
