In general, research on how the human brain processes language has mostly focused on a very small set of familiar, related European languages like English, Dutch, German, Spanish and French. We know almost nothing about how the brains of speakers of most of the world's languages respond to even simple tasks like processing a single word. Not only does this limit our scientific knowledge, it also has the effect of making only a few languages seem worthy of scientific study. Our [ESRC funded project][1] will investigate a wider range of under-investigated languages. These languages will include other Indo-European languages like Slovenian and Bosnian/Croatian/Serbian, and Bangla. We will also include Arabic and Tagalog. We'll use the same simple experiment to show speakers of these languages words which break either a category rule (reidea) or a semantic rule (unsmile) to see whether the brain responses we have observed in previous research with English and Greek are truly universal, and how different word-formation processes might use the same basic language network in different ways. While still leaving the vast majority of the world's languages under-investigated, the aim of this project is to provide a template that can be extended to a much wider range, and to advocate for the scientific and social benefits of systematic, comparative cross-lingustic neurolinguistics.
