实验使用不同的范例，包括快速歧视，表明音高和视觉感知的大小相互作用的感知，较高的音高是一致的较小的尺寸。虽然几乎所有这些研究都使用静态刺激，在这里，我们研究动态音高和动态大小的相互作用，使用加纳的快速歧视范式。实验1研究了音高的连续上升/下降和物体大小的增加/减少的相互作用。实验2研究了静态音高和大小（稳定的高/低音高和大/小视觉对象）的相互作用，使用相同的程序。结果表明，静态和动态的听觉和视觉刺激以相反的方式相互作用。而对于静态刺激（实验2），更高的音高与较小的大小一致（如早期的工作所建议的），对于动态刺激（实验1），上升的音高与增长的大小一致，下降的音高与缩小的大小一致。此外，虽然静态刺激（实验2）表现出一致性和加纳效应，动态刺激（实验1）目前一致性效应没有加纳干扰，一种模式，这是不符合加纳的范式的普遍解释。我们对这些结果的解释主要集中在动态任务中的处理试验内变化的影响，并在距离的变化与隐含的变化明显的大小的关联。结果表明，静态和动态的刺激可以在其跨模态映射有很大的不同，并可能依赖于不同的处理机制。
Experiments using diverse paradigms, including speeded discrimination, indicate that pitch and visually-perceived size interact perceptually, and that higher pitch is congruent with smaller size. While nearly all of these studies used static stimuli, here we examine the interaction of dynamic pitch and dynamic size, using Garner's speeded discrimination paradigm. Experiment 1 examined the interaction of continuous rise/fall in pitch and increase/decrease in object size. Experiment 2 examined the interaction of static pitch and size (steady high/low pitches and large/small visual objects), using an identical procedure. Results indicate that static and dynamic auditory and visual stimuli interact in opposite ways. While for static stimuli (Experiment 2), higher pitch is congruent with smaller size (as suggested by earlier work), for dynamic stimuli (Experiment 1), ascending pitch is congruent with growing size, and descending pitch with shrinking size. In addition, while static stimuli (Experiment 2) exhibit both congruence and Garner effects, dynamic stimuli (Experiment 1) present congruence effects without Garner interference, a pattern that is not consistent with prevalent interpretations of Garner's paradigm. Our interpretation of these results focuses on effects of within-trial changes on processing in dynamic tasks and on the association of changes in apparent size with implied changes in distance. Results suggest that static and dynamic stimuli can differ substantially in their cross-modal mappings, and may rely on different processing mechanisms.
