By narrating "The Yellow Wallpaper" in first-person point of view, the author expects the reader to learn about the story from the perspective of the character who serves as narrator. This means that readers will only know as much as the character perspective or point of view reveals, whereas by means of a different type of narrator - such as in third-person narrative, readers might learn aspects of the story from different perspectives, and different characters. In the case of first-person narrative, as the narrator is also a character, it is likely readers only learn about part of the information, or only a side of the story, which makes it a great narrative device, allowing the author to reveal a truth at the end of the story which will surprise the reader, and give him a full understanding of those situations in the story which may not be clear as they are told from the point of view of a character.
