About me
Photos by Sander Martens
I'm an assistant professor at the department of experimental psychology of the University of Groningen in the Netherlands. My main research interests are eye movements, pupillometry, and perception. I also maintain www.cogsci.nl and develop OpenSesame.

Feel free to send me an e-mail: s.mathot@cogsci.nl
I kindly ask that you post support questions (for OpenSesame and other software packages) on the forum. I do not provide technical support through e-mail.
Miscellaneous writing
I occasionally write blogs about (my) research, academic publishing, and other 'meta-scientific' topics. A selection of posts about my own research:
- How to write with your mind? (or: Decoding attention through pupillometry)
- Can you see while your eyes move?
- Boerke and the tell-tale pupils
- A bit about pupil size, attention, and inhibition
- A bit about our open-science Marie Curie project
- Taking the high road to publication: My experience with pre-prints and data sharing
- Pupils pay attention!
A selection of posts about miscellaneous topics:

About my research
Broadly speaking, my research is about eye movements and perception.
I've recently become interested in pupillometry, and particularly in the role that pupil-size changes play in how we perceive the world. Why do our pupils constrict (become smaller) when we look at something bright? And how is the pupillary light response modulated by things like attention, working memory, and eye movements? Why do our pupils dilate (become bigger) when we become aroused? And what is the link between arousal-related dilation and the light response? These are all questions that fascinate me. If you want to read more about this topic, see our recent papers on the topic, and in particular my review article in Journal of Cognition.
The video below shows the most widely known pupillary response, and the focus of much of my research: the pupillary light response. This video is based on real data of me viewing an alternating sequence of black and white displays.
To see what (or rather: one of the many things that) you can do with pupillometry, check out this video:
Which I explain in more detail here:
And another video in which I talk about (and speculate on) the relationship between pupil size and arousal:
During my PhD project at the VU University Amsterdam, I focused on visual stability: How do we construct a stable and complete representation of our environment--if indeed we do!--despite the incompleteness and instability of visual input at the level of the retina? In the video below, you see schematically depicted how the retinal image (on the left) changes as we make eye movements across a visual scene (on the right).
Scientific publications, presentations, etc.
Research in progress (pre-prints)
The pre-prints listed below have been made available for community feedback, and to share our newest findings as quickly as possible, prior to formal publication. However, these pre-prints have not yet undergone peer review and may be revised as the work progresses.

Data and experimental resources
All my recent (empirical) manuscripts include a link to a public repository that contains participant data, analysis and experimental scripts, and other relevant resources. An example of such a repository is:
For older studies, I have uploaded the data to the following repository:
OpenSesame
I'm the lead developer of OpenSesame, an open-source graphical experiment builder for the social sciences. OpenSesame is a tool for creating psychological experiments with a minimum of fuzz. Below you can see a demonstration video:
