Cognitive and Developmental Aspects of Multilingualism

The goal of our research is to understand and explain the development, representation and processing of multiple languages during the lifespan. We investigate language acquisition and processing in a range of populations, including late second language learners and simultaneous and successive bilingual children, in both instructed and naturalistic settings. Cross-linguistic comparisons include a range of languages (English, Dutch, French, German, Greek, Spanish, and Turkish).

Our group also actively engages in a range of outreach activities, including of course our very own Kletskoppen child language festival.
