Symposium 2025
With the trend of true crime podcasts, we believe to know quite a bit about the world of crime. But is this knowledge just speculation or are we true professionals in Forensics?
Join us at this year's Symposium to learn more about Forensic Psychology!
A Symposium is a whole day of lectures and workshops on a certain topic. This year's topic is "Forensic Psychology, Criminally Interesting". On the 4th of June speakers from all over the Netherlands have been invited to discuss with you different aspects of Forensic Psychology. We will talk about negotiation skills, forensic care, risk assessment, disclosure of evidence and more! Apart from this, we will provide you with a free lunch, free coffee and tea for the whole day, and some goodies for each participant.
The participation fee is €8 for Dimensie members. Or €10 for Psychology students.
You can sign up here!

These are our speakers!

Mind matters: Navigating mental health with empathy and awareness.
This workshop offers a deeper understanding of mental health and how to approach it with awareness and empathy. You’ll explore what mental health really means, why it’s essential for everyone, and gain insight into the stigma that often affects specific communities. In the second half of the workshop, we shift from theory to practice. Through interactive carousel-style roleplays, you’ll develop skills in empathetic listening—an invaluable tool for police negotiators and anyone working in people-focused roles.
