The largely automatic mapping observed between space and sensory magnitudes suggests representation by a single system across domains. Using stimulus response compatibility tasks, the study confirms that a relative, auditory magnitude such as loudness shows a spatial compatibility effect similar to those evidenced for visual sensory domains but only with comparison tasks and for vertically oriented responses. No effect is seen when participants track changes in amplitude or when responses are oriented vertically. In a bimodal context, the study tested whether the spatial mapping of magnitude in 1 sensory modality (loudness) interacts with the spatial representation of magnitude in another sense (luminance). Observed interactions across modalities suggest overlap of magnitude representation across distinct sensory domains, whereas the absence of an effect for dynamic changes in loudness suggests that it is useful for decisions to act on 1 of several objects rather than for tracking magnitude changes in 1 object.

在空间与感官量级之间观察到的基本自动映射表明，跨领域由单一系统进行表征。通过刺激反应兼容性任务，该研究证实，诸如响度之类的相对听觉量级显示出与视觉感官领域所证明的类似的空间兼容性效应，但仅在比较任务以及垂直定向反应中如此。当参与者追踪振幅变化或反应垂直定向时，则未观察到效应。在双峰情境中，该研究测试了一种感官模态（响度）中的量级空间映射是否与另一种感官（亮度）中的量级空间表征相互作用。观察到的跨模态相互作用表明，不同感官领域之间存在量级表征的重叠，而响度动态变化不存在效应表明，这对于在多个物体中的一个上采取行动的决策有用，而非用于追踪一个物体中的量级变化。（《心理学文摘数据库记录》 ）
