Participating in the institute's research
Why should I participate?
For our research, we rely on volunteers to participate in our experiments. It is the participation of volunteers that enables us to do science.
As a compensation for your time, we also pay our participants. Currently, we pay €4 for experiments taking up to 30 minutes and €8 for experiments taking 30 to 60 minutes.
How can I participate?
You can register as a participant by filling in an online questionnaire at www.mpi.nl/ppreg. Please note that it is (at the moment) only available in Dutch. After registration, you will be invited to participate in experiments by our researchers.
If you have any questions, please contact Annelies van Wijngaarden at exp_info@mpi.nl or 024-3521232.
How do I cancel an appointment?
If you are not able to come to the appointment, please let us know as soon as possible. You can call the reception desk at 024-3521911.
How do I unsubscribe?
You can unsubscribe at any moment by going to www.mpi.nl/ppreg. Please note that, due to administrative reasons, you might receive a few more invitations to our experiments.
