Dr Oren Griffiths
My research focuses upon the cognitive mechanisms implicated in learning and belief-updating. I have a particular interest in trial-and-error learning, and how biases and short-cuts can result in erroneous or problematic beliefs (e.g. superstition, anomalous or delusional beliefs). I am also a practicing clinical psychologist with an interesting in cognitive & behavioural therapies for psychosis (e.g. schizophrenia, bipolar, 1Ep).
Currents projects: the "outcome predictability" bias, prediction errors and EEG & metacognition in anomalous beliefs. For more information, please contact the lab through the contact page, or find me at Twitter, GoogleScholar, ResearchGate, Publons or the Flinders University website. For information about my clinical practice, please see here.
