Crossmodal correspondences are consistent associations between sensory features from different modalities, with some theories suggesting they may either reflect environmental correlations or stem from innate neural structures. This study investigates this question by examining whether retinotopic or representational features of stimuli induce crossmodal congruency effects. Participants completed an auditory pitch discrimination task paired with visual stimuli varying in their sensory (retinotopic) or representational (scene integrated) nature, for both the elevation/pitch and size/pitch correspondences. Results show that only representational visual stimuli produced crossmodal congruency effects on pitch discrimination. These results support an environmental statistics hypothesis, suggesting crossmodal correspondences rely on real-world features rather than on sensory representations.
跨通道对应是指来自不同感觉通道的感觉特征之间的一致关联，一些理论认为它们可能反映环境相关性，或者源于先天的神经结构。本研究通过考察刺激的视网膜拓扑特征或表征特征是否会引发跨通道一致性效应来探究这个问题。参与者完成了一项听觉音高辨别任务，该任务与视觉刺激配对，这些视觉刺激在感觉（视网膜拓扑）或表征（场景整合）性质上有所不同，涉及高度/音高和大小/音高对应关系。结果表明，只有表征性视觉刺激对音高辨别产生了跨通道一致性效应。这些结果支持了一种环境统计假设，表明跨通道对应依赖于现实世界的特征而非感觉表征。
