(2) Observers can flexibly prioritize one sense over the other, in anticipation of modality-specific interference, and use only the most informative sensory modality to guide behavior, while nearly ignoring other modalities (even when they convey substantial information). 8/9

In these four experiments, we concluded that (1) observers use both hearing and vision when localizing static objects, but use only unisensory input when localizing moving objects and predicting motion under occlusion. 7/9

In Exp. 3 the target did not move, but only briefly appeared as a static stimulus at the exact same endpoints as in Exp. 1 and 2. Here, a substantial multisensory benefit was found when participants localized static audiovisual target, showing near-optimal (MLE) integration. 6/9

In Exp. 2, there was no occluder, so participants were required to simply report where the moving target disappeared from the screen. Here, although localization estimates were in line with MLE predictions, no multisensory precision benefits were found either. 5/9

In these two experiments, we showed that participants do not seem to benefit from audiovisual information when tracking occluded objects, but flexibly prioritize one sense (V in Exp 1A and A in Exp 1B) over the other, in anticipation of modality-specific interference. 4/9

We asked whether observers optimally weigh the auditory & visual components of audiovisual stimuli. We therefore compared the observed data to maximum likelihood estimation (MLE) model predictions, which weighs the unisensory inputs according to their uncertainty (variance). 3/9

In Exp. 1A, moving targets (auditory, visual or audiovisual) were occluded by an audiovisual occluder, and their final locations had to be inferred from target speed and occlusion duration. Exp. 1B was identical to Experiment 1A except that a visual-only occluder was used. 2/9
