Quantifying folk perceptions of dialect boundaries. A case study from Tuscany (Italy)

Abstract

Abstract This paper aims to understand the contribution of geographical information in the perception of linguistic variation. A total of 813 mental maps collected among young speakers from different cities in Tuscany have been analyzed via an open-access web dialectometric tool (Gabmap). In particular, the study seeks to verify the role of geographic distance and the place of residence of the respondents in modeling perceived variation. The relationship between dialect grouping as made by linguists and perceived taxonomies of sublinguistic areas is also investigated. Results show that geographical proximity between mapped areas significantly predicts the perception of dialect similarity. Our participants made their decisions looking at (1) a keen sense of spatial contiguity, and (2) the synchronic presence of linguistic differences between the Tuscan subregions. Moreover, classification uncertainty grows when the mapped areas are very close to, or very distant from, the participants’ places of residence. Methodological and linguistic perspectives of mental maps in folk linguistics are finally discussed.
