BIDIALECTALISM: refers to a context where individuals acquire two (vernacular) varieties (e.g., spoken dialects) and/or one or more written varieties of the same language (e.g., Norway’s two official written varieties, Nynorsk and Bokmål).
The GOAL with this project is to better document bidialectalism and effects of dialect use/congruency on Norwegian language processing:
How do speakers represent narrow linguistic variation between dialects they are exposed to?
How empirically dis/similar is bidialectalism from other types of multilingualism?
How is the processing of written languages (e.g. Bokmål/Nynorsk) influenced by one’s dialect?
How are bidialectal outcomes shaped by individual degrees of dialect engagement/exposure?
BIDIALECTAL LANGUAGE REPRESENTATION: Bidialectals acquire linguistic systems which are alike in most domains but which can vary in lexicon, morphosyntax, and/or phonology. This study represents the first large-scale (n = 225) EEG study, exploring how cross-dialectal differences are represented in the minds of bidialectal speakers.
DIALECT-SPECIFIC PROCESSING: ERP waveforms and non-agreement minus agreement scalp topographies for predicate adjectival number agreement among Northern Norwegian dialect speakers tested in two modes. The opposite polarity responses reveal contrasting dialect-specific processing: Bokmål (obligatory agreement, e.g., bilene var rød-e/*rød- 'the cars were red-PL/*-Ø) versus Northern Norwegian dialect (prohibited agreement, e.g., bilan va *rød-e/rød- 'the cars were red-*PL/-Ø). The overall weak responses reflect significant cross-dialectal influence.
