On December 10th, Ricardo Cachucho (right photo, on the left) successfully defended his PhD thesis "Methods and tools for Mining Multivariate Time Series”, supervised by Joost Kok and Arno Knobbe at the Leiden Institute of Advanced Computer Science. Ricardo was the first to develop means for us to study children's movements on the playground, which has allowed us to measure the frequency and duration of children's interactions during play. We now widely apply this innovative method in all of our follow-up studies. During his PhD defense, Ricardo was able to expertly bridge the gap between Computer Science and Psychology. 

Parabens Dr. Cachucho!

Who are we?

Group picture 2016 crop2

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), and the Centre for Autism. 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 with hearing impairments, 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, see an overview of our publications per topic, or read about opportunities for students to join our team.
