处理幅度构成了跨多个维度的共同体验，例如当人们必须比较大小、持续时间、数字、声音高度或响度时。然而，从认知的角度来看，我们仍然不清楚所有这些经验是依赖于一个共同的系统，还是依赖于不同的系统，这些系统或多或少都有很强的关联。观察空间维度和数字维度之间的这种干扰的一个特别引人注目的方法是，通过仅仅感知不相关的数字刺激来引发大小判断的偏差。然而，在这样的实验背景下，两个问题仍然是开放的。首先，我们仍然不知道偏误的方向是与数字的大小有关，还是与它们在有序序列中的位置有关，因此可以由其他非数字有序序列（如字母表中的字母）引起。其次，目前还不清楚所观察到的相互作用是否可以推广到其他连续的大小维度，如亮度。在这里报道的研究中，字母和数字都被用于大小和亮度再现任务。我们观察到，在复制大小时，两种类型的刺激之间存在分离，这种错觉仅由数字引起。然而，当再现亮度时，字母和数字都没有引起偏见。这些研究结果表明，虽然只有数字大小，而不是字母，elecdates大小知觉的偏见，幅度和亮度的同时处理不会带来同样的错觉，支持这两个维度的处理相对独立的想法。
Processing magnitudes constitutes a common experience across multiple dimensions, for example when one has to compare sizes, duration, numbers, sound height or loudness. From a cognitive point of view, however, it is still unclear whether all these experiences rely on a common system, or on distinct systems, with more or less strong associations. One particularly striking way of observing such interference between the spatial and numerical dimensions consists in eliciting a bias in size judgment through the mere perception of irrelevant numerical stimuli. In such experimental context though, two questions remain open. First, it is still unknown whether the direction of the bias is related to the magnitude of the number presented, or to their position in an ordinal sequence, and thus could be elicited by other non-numerical ordinal sequences such as letters of the alphabet. Second, it is still unclear whether the observed interactions generalize to other continuous dimension of magnitude such as brightness. In the study reported here, both letters and numbers were used in a size- and a brightness-reproduction task. We observed a dissociation between the two types of stimuli when reproducing size, the illusion being elicited solely by numbers. When reproducing brightness, however, neither the letters nor the numbers elicited a bias. These findings suggest that, while only numerical magnitude, and not letters, elicits a bias in size perception, the concurrent processing of magnitude and brightness does not bring about the same illusion, supporting the idea of a relative independence in the processing of these two dimensions.
