We examine whether crossmodal correspondences (CMCs) modulate perceptual disambiguation by considering the influence of lightness/pitch congruency on the perceptual resolution of the Rubin face/vase (RFV). We randomly paired a black-and-white RFV (black faces and white vase, or vice versa) with either a high or low pitch tone and found that CMC congruency biases the dominant visual percept. The perceptual option that was CMC-congruent with the tone (white/high pitch or black/low pitch) was reported significantly more often than the perceptual option CMC-incongruent with the tone (white/low pitch or black/high pitch). However, the effect was only observed for stimuli presented for longer and not shorter durations suggesting a perceptual effect rather than a response bias, and moreover, we infer an effect on perceptual reversals rather than initial percepts. We found that the CMC congruency effect for longer-duration stimuli only occurred after prior exposure to the stimuli of several minutes, suggesting that the CMC congruency develops over time. These findings extend the observed effects of CMCs from relatively low-level feature-based effects to higher-level object-based perceptual effects (specifically, resolving ambiguity) and demonstrate that an entirely new category of crossmodal factors (CMC congruency) influence perceptual disambiguation in bistability.

我们通过考虑亮度/音高一致性对鲁宾脸/花瓶（RFV）感知分辨率的影响来检查跨模态对应（CMC）是否调节感知消歧。我们将黑白 RFV（黑脸和白花瓶，或反之亦然）与高音或低音随机配对，发现 CMC 一致性会偏向主导视觉感知。与音调（白/高音或黑/低音）CMC 一致的感知选项的报告频率明显高于与音调（白/低音或黑/高音）CMC 不一致的感知选项。然而，仅在较长而不是较短持续时间的刺激下观察到该效应，这表明感知效应而不是反应偏差，而且，我们推断对知觉逆转而不是初始感知的影响。我们发现，较长持续时间刺激的 CMC 一致性效应仅在预先暴露于刺激几分钟后发生，这表明 CMC 一致性随着时间的推移而发展。这些发现将 CMC 的观察到的效果从相对较低水平的基于特征的效果扩展到更高水平的基于对象的感知效果（特别是解决歧义），并证明一类全新的跨模态因素（CMC 一致性）影响感知消歧双稳态。
