According to proponents of the generalized magnitude system proposal (GMS), SNARC-like effects index spatial mappings of magnitude and provide crucial evidence for the existence of a GMS. Casasanto and Pitt (2019) have argued that these effects, instead, reflect mappings of ordinality, which people compute on the basis of differences among stimuli that vary either qualitatively (e.g., musical pitches) or quantitatively (e.g., dots of different sizes). In response to our paper, Prpic et al. (2021) argued that both magnitude and ordinality play a role in SNARC-like effects. Here, we address each of their arguments and conclude that magnitude is relevant to these effects only insofar as it serves as a basis for ordinality. For this reason and others, SNARC or SNARC-like effects cannot provide evidence for the putative generalized magnitude system.
根据广义大小系统提议（GMS）的支持者的观点，SNARC 类似效应索引了大小的空间映射，并为 GMS 的存在提供了关键证据。卡萨斯安托和皮特（2019 年）认为，这些效应反映了序数的映射，人们根据刺激之间的差异进行计算，这些差异要么是定性的（例如，音乐音高），要么是定量的（例如，不同大小的点）。针对我们的论文，普里皮奇等人（2021 年）认为，大小和序数都在 SNARC 类似效应中起作用。在这里，我们将对他们的每一个论点进行回应，并得出结论，只有当大小作为序数的基础时，它才与这些效应有关。由于这个原因和其他原因，SNARC 或 SNARC 类似效应不能为所谓的广义大小系统提供证据。
