Research Biography

My research focuses upon the cognitive mechanisms implicated in learning and belief-updating. My basic science examines how "trial and error" lerning takes place, and the role of attention and beliefs in guiding learning. I am also interested in the cognitive mechanisms that bring about unsupported, idiosyncratic or erroneous beliefs (e.g. delusions, anomalous beliefs, superstitions). This research programme aligns with my primary clinical interest, which is in cognitive & behavioural therapies for psychosis (e.g. schizophrenia, bipolar, 1Ep).
