Interests

Whilst our actions are often goal-directed, slips of action reveal that automatic, or habitual, mechanisms can take over. Although the concepts of goal-directed action and habits are well-grounded in folk psychology, most empirical research so far has taken place in the field of animal learning rather than human decision-making. I therefore develop learning and response priming tasks -based on animal models- to investigate the associative and motivational mechanisms mediating goal-directed and habitual actions in humans and I use the technique of fMRI to study the neural substrates. My current research also focuses on disruptions of instrumental learning mechanisms (e.g. in Parkinson's Disease, obesity, addiction and obsessive-compulsive disorder).
