“If we take the predictive processing model as our most-accurate-yet description of how cognition works, we gain insight into how a piece of art or literary text (for example) interacts with our sensory and analytical systems. We gain a vocabulary for talking about what a “schema,” or cognitive knowledge structure, is, and what it means for that structure to learn from surprising events and prediction errors, and how expectations and beliefs at the structure’s highest level can radically distort how sensory experiences are processed at its lowest.”
