The target article argues that language-of-thought hypothesis (LoTH) is applicable to various domains, including perception. However, it focusses exclusively on the visual case, which is limited in this regard. I argue for two ideas in this commentary: first, their case can be extended to other modalities such as touch; and second, the status of those six criteria needs to be further clarified.

Some sensory modalities, such as sight, touch and audition, are arguably spatial, and one way to understand these spatial senses is to investigate spatial representations in them. Here I focus on a specific element in this area— the interplay between perspectival variation and spatial constancy—and discuss recent interdisciplinary works on this topic. With these relevant experimental works, we will see clearly how traditional controversies in philosophy, for example, whether we perceive perspectival shapes as well as objective shapes, and whether any (...) sensory field should be postulated in senses other than vision, can benefit from considerations in empirical sciences.
