Sign up for research


We study the development of language, social interaction, cognition and the wellbeing of mother and child. Topics that apply to all parents and children!

We have three different locations in Nijmegen, all at the Radboud University campus. Some studies will take place here, others are online. We may also visit you at home, if you agree.

Participating in a study can mean several things. Sometimes children play a game, or we let them watch a short video while we measure their eye movements, for example. We also use questionnaires. Parents stay with their child at all times.

The duration of the studies varies a lot. Some take about half an hour, others will take the whole day.

Are you pregnant or do you have a child younger than six years old? Please sign up below!

Once you signed up, you will enter our database. When we start a project on mothers in a certain week of their pregnancy, or on children of a certain age, we will invite you if you or your child meet these requirements.

Is this a bad time? No worries; per study you decide whether you want to participate.

Participating in our research means that you are contributing to new knowledge on the development of baby and child.

The more we know, the better we can support children's development!

Thank you for participating! We now know a little bit more about the development of baby and child. 

To thank you, you will receive a gift or a small amount of money after participation. This may differ per study; you will be informed before taking part.
