I am interested in cognitive and emotional processes in addictive behaviour. My focus is on maladaptive information processing of food and alcohol related information, so-called cognitive biases. The aim is to investigate whether those biases are different in individuals with strong preferences for food and alcohol. I’m intrigued by how these biases depend on individual traits (e.g. impulsivity) and genetics. I am using a variety of behavioural tasks that assess motivational action tendencies and reward sensitivity in combination with genetics in healthy human volunteers. I am also interested in how cognitive training can modify these cognitive biases. This research is relevant for understanding underlying mechanisms in addiction, with relevance for the development of new therapies for this disorder.
