b) Picture-word interference test
c) Language- and task switching tests

Achtergrond van het onderzoek
The main objective of this observational study is to investigate whether the with bilingualism associated advantages in executive control have a beneficial influence on people with aphasia, and if these benefits aid functional communication. In investigating this, the study also aims to add to the knowledge of the recovery of more than one languages after acquired neurological brain damage. Finally, the findings of this study will contribute to the growing body of research investigating the interplay between language abilities skills and executive control in individuals with aphasia and neurologically healthy individuals.
