About

I’m a PhD candidate at the Behavioural Science Institute, Radboud University, Nijmegen. My main research interests concern mobile technologies, in particular the effects of permanent availability via smartphones. At the same time, I’m a strong supporter of preregistration and Open Science.

The PhD project deals with the effects of smartphone use on cognitive processes and the question if and how these effects might occur. I mostly conduct laboratory experiments, surveys, as well as field studies combining experience sampling and smartphone logging. My supervisors are Harm Veling and Moniek Buijzen.

Currently, I’m visiting the Healthy Cognition Lab at the School of Psychology at University of Glasgow.

Calculating and visualizing error bars for within-subjects designs

What this post is about Creating data Creating a violin plot (with wrong errors bars) Creating another plot (with error bars that’re still wrong) The last plot (this time correct) What this post is about Personally, I find violin plots with error bars a great way to present repeated-measures data from experiments, as they show the data distribution as well as the uncertainty surrounding the mean. However, there is some confusion (at least for me) about how to correctly calculate error bars for within-subjects designs.
