What is the author's style in The Jilting of Granny Weatherall by Katherine Anne Porter?

One of the most striking stylistic aspects of "The Jilting of Granny Weatherall" is its unusual narrative perspective. Though the story is written in the third person, its narrative point of view is extremely close to that of the central character, Granny Weatherall. The story is told through stream-of-consciousness. Granny's thoughts are presented in a spontaneous fashion, as if readers had access to her thoughts at the moment each one occurs to her. Porter conveys what it is like to be an eighty-year-old woman whose mind tends to wander by enabling readers to experience some of the same confusion Granny feels. Since Granny sometimes mistakes one daughter for another, for example, the characters in the story sometimes dissolve and become other characters. Because Granny's awareness slips back and forth between her present reality and her remembered past, events in the story are presented as they occur to Granny rather than chronologically.
