LEX Joint Research Project on Multilingualism and the Brain

Dr. Suzanne Flynn, Professor of Linguistics and Language Acquisition at MIT and Dr. Kuni Sakai, Professor at the University of Tokyo who is involved in neuroscience and linguistic research have embarked on a series of research projects on multilingualism and the brain.  The first project was conducted using fMRI machines in Dr. Sakai's Lab at the University of Tokyo and examined to what extent multilingualism provides cognitive and linguistic benefits.  Participants included trilingual LEX members, as well as non-members.  

The exciting first results were published March 31, 2021 in the journal, Scientific Reports.  Using fMRI and behavioral analyses, the researchers found that multilinguals have a demonstrated neural advantage over bilinguals in acquiring new languages.  This confirms the cumulative-enhancement model -- “The more languages you know the easier it gets.” -- developed by Dr. Flynn based on previous behavioral studies.  Visit this report to read all about it!

Current Research on Bilingualism

Multlingualism is the natural state for humans1 and is beneficial to individuals cognitively, linguistically, and socially.2  Multilingualism also benefits society through the facilitation of cross-cultural under-standing and communication.3 More than two thirds of the world is bilingual or multilingual.4  ​
​
Existing research on bilingualism demonstrates cognitive advantages to children and adults in the following areas: executive function--ability to pay attention, plan and organize, and remember details;6 mental flexibility;7  abstract thinking;8 metalinguistic skills--awareness and control of linguistic components, including awareness of the listener and ability to speak appropriately in different situations;9 and delay in onset of symptoms of dementia and Alzheimers.10

Current Research on Multilingualism

While there is not as much research available on multilingualism, anecdotal information and a couple of studies suggest that these positive effects are multiplied with multilingualism.  For example, “Ellen Bialystok at York University in Canada has found that speaking two languages delayed dementia diagnosis by five years. Those who knew three languages, however, were diagnosed 6.4 years later than monolinguals, while those fluent in four or more languages enjoyed an extra nine years of healthy cognition.”11

LEX has accumulated anecdotal evidence that it is more effective to learn several languages at one time, and that a multilingual/multicultural approach is the surest way to create shining young people who will be the global citizens and leaders of tomorrow.  We look forward to the results of our new research projects.
