I'm currently working as a PhD student at the Department of Cognitive Psychology at the Vrije Universiteit, Amsterdam. My main research interests are the interactions between attention and visual stability and the interactions between action and perception. You can find a list of my publications and awards here. I also maintain www.cogsci.nl and occasionally make some music. You may also be interested in OpenSesame, an open-source graphical experiment builder that I have been developing.

Visual stability

Even though we perceive the world as stable and continuous, visual input actually consists of a series of "retinal snapshots". What we are trying to find out is how we are able to create a stable and useful perception of the world, based on this seemingly incoherent and unstable input. [Download in .avi format]

Eye movements

In the video below, you can see the eye movements of two children (red and green) watching an animation of an aquarium. By tweaking parameters of the video, such as how often events occur, we can use this type of animation in an experimental setting.

OpenSesame

OpenSesame is a graphical experiment builder. Basically, it's a tool for creating psychological experiments without having to do too much programming (although you can use Python code as well). Below you can see a demonstration video. You can find out more about OpenSesame here.
