I work the Human-Technology Interaction group at Eindhoven University of Technology. I publish on how to design and interpret studies, applied (meta)-statistics, and reward structures in science. My main lines of empirical research focus on conceptual thought and meaning. I love to teach (and was elected as the best teacher of a BA course at Eindhoven University of Technology in 2014, and received the 2017 Leamer-Rosenthal prize for Open Social Science as a Leader in Education), especially about research methods to young scholars (you can follow my free Coursera course here). I prioritize review requests based on how much the articles adhere to Open Science principles. I believe science should be a much more collaborative enterprise (see my TEDx talk on this topic here). I'm currently funded by a VIDI grant from NWO on a project that aims to improve the reliability and efficiency of psychological science.

Statistics and Methodology

I blog on methods and statistics here, and I regularly teach workshops on methods and statistics. In the last few years I've developed an interest in the importance of (preferably pre-registered) replications and ways to improve how we interpret and design studies. I think we can try a little harder to make science as open and robust as possible, and give the tax payer as much value for money as we can. I have written a practical primer on how to calculate and report effect sizes for ANOVAs and t-tests - it includes an easy to use spreadsheet to calculate effect sizes. I've also written a practical primer on how to analyze result repeatedly while collecting data using sequential analysis. And I've written a practical primer on equivalence tests, including my first R package 'TOSTER'. For a recent article on how to evaluate and increase the informational value of studies, read this.

Empirical Research

I've examined how people can use concrete information (e.g., spatial distance, brightness differences) to structure their thoughts about more abstract things (e.g., valence, power, time). One of my interests is when such associations might be embodied, and when not, and how to improve the empirical and theoretical grounding of social embodiment. In other studies I have investigated how groups emerge from individuals through movement synchronization. For an overview chapter on the behavioral consequences of movement synchrony, see this. Further interests include the meaning of colors, such as the relation between the valence and brightness of affective pictures, conceptual similarity, but I also like to play around with gadgets, for example to use a smartphone to measure heart rate changes during emotional responses. I supervise the PhD of Anne Schietecat who works on associations between brightness and aggression, and Chao Zhang who works on behavior change through e-coaching.
