Probability designs : literature and predictive processing Probability Designs develops a comprehensive account of the predictions and probabilities at play in literature in particular novels. Novels it is argued provide readers with a designed sensory flow in their plots style and relation to other texts. The model traces based on research in predictive processing how this designed sensory flow revises readers expectations and leads them to engage in exploratory thinking. The model is then embedded in a co evolutionary account of how language writing and fictionality enable literary designer environments in which thought can be extended beyond the everyday. Literary form as traced in probability designs performs particular cognitive work in these designer environments
