Perceptual and cognitive identification

Scientific framework and objectives

Although the cognitive representation and processing of language have been studied through complementary approaches for quite a few years, several questions remain unanswered owing to the complexity of the problem. Language identification provided a paradigm well suited to the study of the cognitive representations of foreign languages through perceptual experiments and functional cerebral imaging.

We are assessing the perceptual strategies human listeners resort to when identifying languages (especially Afro-Asian languages) and dialects (Arabic dialects and now, British dialects). The aim is to better comprehend how the human brain processes the notion of linguistic distance. Our aim is to determine a critical linguistic distance above which different languages require differential cognitive processing. We compare linguistic distances – as measured in typological studies (phonological systems, the lexicon, rhythm and intonation) – with those obtained from perceptual experiments based on natural or synthesized speech. We also investigate the cerebral correlates of the processing involved using specific methods (ERP, fMRI, etc.).
