What effect doe cumulative on the reader?

Cumulative effects in literature create a sense of depth and resonance by layering details, themes, or emotions over time, allowing readers to build a more profound understanding of characters and situations. This technique can enhance the emotional impact of a narrative, as repeated motifs or escalating tension draw readers deeper into the story. Ultimately, it fosters a more immersive reading experience, making the narrative's climax or resolution feel more significant and satisfying.
