What technique can a writer use to show a character's past experience?

Using flashback as a technique allows a writer to provide insight into a character's past experiences directly within the story's current timeline. This method enables the reader to see events that occurred before the main narrative takes place, offering context and depth to the character's motivations, emotions, and decisions. Flashbacks can be implemented through various means, such as vivid memories or recollections triggered by specific situations within the story.

In contrast, chronological narration presents events in the order they occur, which may not effectively convey a character's past unless it happens to align with the storyline's progression. Foreshadowing hints at future events, which does not typically illuminate a character's past experiences. Dialogue, while it can reveal character background through conversation, does not necessarily provide the same direct insight or emotional impact as a flashback would. Thus, flashback stands out as the most effective method for revealing a character's history in a narrative.
