I need a criticism of the style used in "Where Are You Going, Where Have You Been" by Joyce Carol Oates.

I think that you can find different examples out there
about the style used in the Oates short story.  One such analysis focuses on the idea of
psychological realism as the mode through which the story is told.  Connie's
consciousness is how we, as the reader, understand the events that unfold.  From the
opening where there is security and confidence to its slow and steady erosion into the
unknown, the style of psychological realism ends up unsettling both Connie and the
reader.  Through this style, the thematic applications can reveal itself.  The idea of
the novel being an loss of innocence archetype or a feminist text can be divulged
through the style that Oates employs, one that maintains the third person narrative, but
skilfully does so through the consciousness of one of the characters.  It is through
this prism that the reader fully grasps what is happening to Connie and how she has
freedom, but, very much like a Rousseauian character, "lives in
chains."
