Research has shown that perception is an active process. The brain is constantly making predictions about the outcome of sensory events and revising predictions in response to feedback. Discrepancies naturally occur between expected and actual events resulting in ‘prediction errors’ that the brain actively works to resolve. Although prediction errors are transient in nature, they can be observed and measured during tests of sense-function. The longer they persist, the more disruptive they are to tasks involving high-speed sense-discrimination such as speech and reading comprehension. The principles of “predictive brain” are well established in the field of neuro-cognition. This study suggests they apply to the field of social-cognition as well ..and error analysis could be a useful measure of disruptions in social perception that characterize delusions of mental-illness [
