Bilingualism, the knowledge of two or more languages, exists worldwide, and is also growing in the UK. There are many ways to become bilingual, from growing up in a bilingual family to teaching oneself several languages. Each of these ways impacts the way people interact with each other and lead their social life.
Why did we do this study?
We know very little about the experience of autistic bilingual people, compared to what we know from the general population. With this study, we wanted to know more about autistic bilingual people, especially regarding their experience of becoming bilingual, and regarding the way bilingualism had influenced their social life.
What did we do?
297 autistic adults completed an online survey, the Autism and Bilingualism Census, and answered questions about their language profile (i.e. the number of languages they knew, when they started learning these languages, how well they knew the language, etc…), and about their social life quality. They also answered several questions about their experience of being bilingual.
What did we find?
We found that there is a great diversity of language experiences in the autistic bilingual population, just like in the non-autistic bilingual population. We also found that bilingualism could shape the social life quality of autistic people. These are important results as they show that contrary to what we thought, there are many ways for autistic people to encounter a new language, learn it, and use it in their daily life. This study also shows that there is no research at all on the experience of many autistic bilingual people, and they may not have access to the support and resources they need.
We ran 4 other studies on the topic of bilingualism in autism:
- “Autism & Bilingualism – Parents’ perspectives” focused on the experiences of bilingual parents of autistic and non-autistic children
- “Autism, bilingualism, and childhood” focused on the development of autistic and non-autistic children growing up in bilingual environments
- “Autism, Bilingualism, and Cognition – Mind” was the first step of this study and focused on the relationship between bilingualism and the social mind in autistic and non-autistic adults
- “Autism, Bilingualism, and Cognition – Brain” focused on the influence of early bilingualism on the networks of the social brain, in autistic and non-autistic adults
The field of “bilingualism in autism” research is still extremely new, and we have just scratched the surface. There is still a lot to do to better understand the experience of autistic bilinguals.
