This document discusses different narrative structures and theorists. It begins by defining narrative as story structure and devices. It describes linear and circular structures, and how Aristotle and Freytag developed basic plot structures. It then discusses narrative theorists like Todorov and his model of equilibrium, disequilibrium, resolution, and restoration. Next it links Carroll's three phase model of onset, discovery, and disruption to the horror genre. Finally, it notes Todorov also argued narratives involve an initial situation, a disruptive problem, and a resolution reinstating the initial situation.
