A recent theoretical framework has formalized predictive mechanisms in the sensorimotor system. This “predictive coding,” also called the agent-centered approach, has revealed some dysfunctions of prediction in patients with mental disorders such as schizophrenia. The dynamic and hierarchical nature of prediction could be innately aberrant. Therefore, their representation as a generative model of the self and the world is unclear. The current paper discusses (1) the theoretical controversies in subjective probability in the Bayesian perspective and (2) its application for understanding psychotic symptoms or experiences such as delusions and hallucinations for future empirical work.
