29.1 COMPUTATIONAL MODELING OF PERCEPTION AND BEHAVIOR REVEALS HIDDEN INSIGHTS INTO MECHANISMS OF PSYCHOTIC SYMPTOMS

摘要

Because it happens so quickly and automatically, it may be intuitive to think of perception as a passive process in which our brains simply receive input about our surroundings via our sensory organs. However, it has long been clear that perception is, instead, an active process, characterized by the building of an internal model of our environment, blending incoming sensory evidence with prior beliefs about what is around us. Within this framework, hallucinations may be thought to arise from an increased influence of these prior beliefs during perception.
