Our behaviour is the result of a complex process of continuous, mutual influence between ourselves and our environment, especially our social environment. The field of Social Psychology has a long history of investigating how our behaviour changes because of such social influences. My work mainly focuses on making this scientific knowledge about behaviour change available and insightful, for professionals, students, and other interested parties. Such knowledge can help us guide the development and evaluation of interventions promoting sustained behaviour change. At the same time, this knowledge may also help counteract undesirable forms of influence.
I believe it is important that people understand to what extent their behaviour is guided by processes they may not understand or be aware of in the first place. Only then can lasting behavioural change take place.
