Final answer:
Flashbacks are used in 'The House on Mango Street' to provide background information, though specific examples aren't provided in the reference. They are a technique where the story temporarily moves backward in time, which can be seen in Sandra Cisneros's reflective writing in her memoir 'A House of My Own'.
Step-by-step explanation:
Flashbacks are a narrative technique used by authors to provide backstory to the characters or events taking place in the main storyline. Sandra Cisneros employs this technique in her novel The House on Mango Street. However, specific examples of flashbacks in the book aren't provided in the provided information, and thus they must be directly obtained from the text. Generally, a flashback involves shifting the narrative back in time from the current point of the story, as in the example of An Occurrence at Owl Creek Bridge by Ambrose Bierce, where the protagonist's past is revealed amidst his execution on the bridge.
In her memoir, A House of My Own: Stories from My Life, Cisneros uses reflective writing akin to a literary flashback where she revisits her past self from the perspective of the successful author she became. Thus, the memoir can be seen as an extended form of flashback, creating a dialogue between her past and present selves and shedding light on her life experiences that shaped her writing career.
