Who are we?

FOE group 2019 crop

Our team is located at the department of Developmental Psychology of Leiden University in the Netherlands. We work in close collaboration with the Dutch Foundation for the Deaf and Hard of Hearing Child (NSDSK), the ENT department of the Leiden University Medical Centre (LUMC), the Centre for Autism, the Leiden Institute of Advanced Computer Science (LIACS), TU Delft, and University of Twente. Our group is dedicated to examining the emotional development of children and adolescents of all walks of life. We have a strong focus on the functionality of emotions, and its impact on children's social development. Besides typically developing children and adolescents, we are interested in the development of those who are deaf or hard-of-hearing, with autism spectrum disorders, or with specific language impairments.

On this site we regularly post news items about new publications, events, and so on. You can also read more about our ongoing projects, read about and download questionnaires we have developed,
