跨模态匹配是基于不同感觉中感知体验强度之间的绝对等效，还是基于相应刺激集内的相对位置？为了帮助回答这个问题，我们进行了一系列的三个实验;在每个实验中，一种模式的刺激强度水平保持不变，而另一种模式的刺激强度水平则随着会话的变化而变化。通过两种方法-幅度匹配和跨模态差异估计-获得的结果在揭示以下方面达成一致：首先，跨模态匹配似乎在所有情况下都代表了绝对对等和相对对等之间的折衷（上下文）比较，对于听觉响度与振动响度以及听觉响度与视觉亮度两者，折衷为约50-50，但是更接近地，尽管不是全部，绝对感知听觉持续时间与视觉持续时间。第二，个体差异丰富，一些科目证明完全绝对匹配，其他完全相对匹配（几乎没有一致性，但是，任务之间或不同对的方式之间的比较）。第三，跨模态差异的判断是一致的线性减法模型，在响度的情况下，基本规模是大致兼容史蒂文斯的sone规模。最后，一个模型设计来描述顺序依赖的反应可以占至少部分的上下文引起的变化，跨模态等价。
Are cross-modality matches based on absolute equivalences between the intensities of perceptual experiences in different senses, or are they based on relative positions within the respective sets of stimuli? To help answer this question, we conducted a series of three experiments; in each the levels of stimulus magnitude in one modality stayed constant while the levels in the other changed from session to session. Results obtained by two methods—magnitude matching and cross-modal difference estimation—agreed in revealing the following: First, the cross-modality matches seem to represent in all cases a compromise between absolute equivalence and relative (contextual) comparison, the compromise being about 50-50 for both auditory loudness versus vibratory loudness and auditory loudness versus visual brightness, but more nearly, though not wholly, absolute for perceived auditory duration versus visual duration. Second, individual variations abounded, with some subjects evidencing totally absolute matching, others totally relative matching (with little consistency, however, between tasks or between comparisons of different pairs of modalities). Third, the judgments of cross-modal difference were consistent with a model of linear subtraction, and in the case of loudness, the underlying scale was roughly compatible with Stevens's sone scale. Finally, a model designed to describe sequential dependencies in response can account for at least part of the context-induced changes in cross-modal equivalence.
