Our laboratory are interested in examining the psychological processes that contribute to the development and maintenance of psychosis, a severe mental illness. Our members focus on the role of cognitive biases, such as attributional style and data-gathering bias, on delusionality and treatment outcome. We also investigate the extent to which cognitive and affective processes may be shared between psychosis and other psychiatric disorders. Our projects cover the continuum of psychosis, from individuals at risk of developing the illness, to patients across the acute and recovery stages. Apart from theoretical projects, we are currently running two treatment trials for psychosis and bipolar disorder respectively. We have also developed an interest in assessing subjective psychological experiences using experience sampling methodology on a mobile phone app.
