Research Interests

I investigate how people can motivate themselves to do difficult or demanding activities rather than being tempted to seek instant pleasure. An important hypothesis is that we possess a mechanism that translates feelings of being strongly engaged into perceptions that a task is valuable. Among some individuals (e.g. action-oriented individuals; people with high achievement motivation) this mechanism appears to work quite naturally, but unfortunately this does not hold for everybody (e.g. state-oriented individuals; people who are low-achievement oriented). In an experimental research program using cognitive, social psychological and physiological measures, it is examined how, why, and when engagement facilitates motivation. The findings are interpreted in light of their implications for self-regulation in the domains of health, consumer behaviour, and learning.

Teaching

In the academic year 2012/13 I teach the self-regulation & health course (together with Dr. Yael De Liver) and an introduction into motivation research.

The weight importance effect

In 2009, my colleagues Daniel Lakens and Thomas Schubert and I published an article in Psychological Science in which we reported that participants who held a heavy compared to a light clipboard were found to assign more importance to questionnaires that were attached to the clipboard.
The studies received a lot of attention inside and outside academia and triggered - to our knowledge - quite some replication attempts.
We consider our work as preliminary and exploratory. We are genuinely interested to learn more about the nature and significance of the effect.
This site is the preliminary attempt (UNDER CONSTRUCTION) to collect all knowledge available including successful and failed replications, moderation, and theoretical explanations. We will update the information as much and as regularly as possible.
