The type of storage structure in which the point of view shifts between two or more characters is commonly referred to as multiple perspectives or multiple points of view. This narrative technique allows the reader to gain insights into the thoughts, feelings, and motivations of different characters, creating a more layered and complex story. It can be used in various formats such as novels, short stories, and even films.
In literature, this technique might be implemented through alternating chapters, sections, or even paragraphs that focus on different characters, and it can enhance themes, build tension, and deepen character development. Examples of this can be seen in works like "The Sound and the Fury" by William Faulkner or "As I Lay Dying," where different characters provide their unique perspectives on the same events.
