Near and "far" in language and perception

A major interest in cognitive science is the relationship between linguistic and perceptual representations of space. One approach to exploring this relationship has been to investigate aspects of the linguistic encoding of space that correspond closely to aspects of the visual system. Another approach, which does not contradict the first but rather complements it, is to investigate ways in which linguistic and visual representations of space are different. This paper pursues the second approach by arguing that the distinction between proximal and distal demonstratives (e.g. this vs. that, here vs. there) does not correspond to an independently established distinction between near and far space in the visual system but is instead based on language-internal factors. Recent neuropsychological and neurophysiological studies suggest that the brain contains separate mechanisms for representing, on the one hand, near or peripersonal space which extends roughly to the perimeter of arm's reach and, on the other hand, far or extrapersonal space which expands outward from that boundary. In addition, crosslinguistic research suggests that it is very common for languages to have two basic types of demonstrative terms - proximal and distal. This parallelism raises the possibility that the linguistic distinction may derive from the perceptual distinction. However, several arguments support the contrary view that the two distinctions are independent of one another. A substantial proportion of languages in the world have demonstrative systems that divide space into three or more egocentrically-grounded regions, thereby violating the two-way perceptual contrast. Even more importantly, empirical studies of how demonstratives are used in ongoing discourse in different languages suggest that they do not encode quantitative spatial information such as within vs. beyond arm's reach; instead, they specify abstract semantic notions that, when combined with the unique pragmatic features of communicative contexts, allow speakers to make a virtually unlimited range of spatial distance contrasts. Thus, demonstratives constitute an interesting case of divergence between linguistic and perceptual representations of space. (C) 1999 Elsevier Science B.V. All rights reserved.
