Complementary studies of learning and motivation in psychosis and pathological hyperphagia

Professor Fletcher uses combinations of cognitive challenges, neuroimaging and psychopharmacological manipulations to explore disturbances in learning, inference, motivation and decision making. His studies are aimed at furthering understanding of how perception and learning may be disrupted, both in the context of the abnormal beliefs and perceptions that characterise certain types of mental illness, and in association with health-harming behaviours such as overconsumption.
