Research program:
Marion is interested in the neurocognitive mechanisms underlying metacognition, learning and decision-making in humans, which she investigates using carefully controlled behavioural experiments in tandem with computational modelling and neuroimaging, in healthy and patient populations.
Her research relates to human meta-cognition-- the ability we have to monitor and evaluate our own cognitive capacities.
Specifically she examines how a sense of confidence changes in the presence and absence of feedback, and its relationship with meta-cognition, at the behavioral, computational and neural levels. She investigates how confidence is built and maintained, and the functional role of confidence signals in guiding learning and decision-making.
In addition, she aims at understanding how a global sense of confidence such as individual self-esteem is built from local, task-dependent confidence. Extensions of this work include the study of metacognitive impairments in psychiatric disorders characterized by changes in self-evaluation.
