This document discusses different types of narrative models, including cohesive and non-cohesive models. Cohesive models include disrupted narratives, which leave out part of the story to create mystery, and non-sequential narratives, which rearrange the order of plot points for emphasis. Disjointed narratives rely on audience assumptions. Non-cohesive models include ergodic narratives with multiple embedded stories, branching narratives that involve audience choices, and multi-linear narratives with intertwining storylines. These different narrative structures aim to keep audiences engaged through mystery, suspense, and interaction.
