In this project, the investigators will explore the cognitive neuroscience of intentional action in relation to food behaviour. To unravel how the brain systems involved in intentional control of actions and how these interact with the reward system in different physiological conditions and in relation to lean-weight or obesity, the investigators will manipulate the degree of intentionality of the behaviours under examination and the level of satiety of the participants.
