Developing a psychophysiological method to examine violations of predictive coding processes

Introduction. The predictive coding theory posits that the brain functions as a “prediction machine”, continuously generating hypotheses based on past experiences and comparing them against actual input signals. This theory is a promising basis for explaining many psychopathological mechanisms. However, experimental approaches to investigate predictive coding processes have not been sufficiently explored. The article introduces a novel psychophysiological method designed to investigate the characteristics of predictive coding processes during variable visual stimulation. The paper outlines the experimental protocol, detailing the scenarios for stimulation, data acquisition, processing, and interpretation. The paper describes the experimental design and presents preliminary results from a pilot study.
