Person entering MRI scanner

We are conducting a study investigating the effects of multilanguage acquisition on cognitive development.

Purpose of the study

The study will help us find out more about the brain - in particular, how the brain learns to speak multiple languages. Only then can we know whether learning and speaking two (or more) languages at a certain point of our lives is beneficial for cognitive development and brain protection from the effect of ageing.

This knowledge will help us to design better educational programmes for healthy children and better treatments for those who have problems.

Who we are looking for

Healthy people, between 7 and 80 years old, are invited.

We are looking for monolinguals (English as native language) and bilinguals/multilinguals (English + any other language/s).

Steps required

Participation in the study will require three steps:

  • Complete online questionnaire that shares information about your linguistic experience (it takes about 15 minutes): select Adults questionnaire or Children questionnaire.
  • Take a test on a series of cognitive measures (memory, attention, verbal and non-verbal tasks) presented on a computer. The session will take approximately 90 minutes.
  • Brain scan at our Magnetic Resonance Imaging (MRI) unit at UCL. The procedure is completely safe and short (approximately 6 minutes in the scanner).
