Mean (± standard error of the mean) late positive potential (LPP) amplitude for participants in the rumination and distraction conditions in (A) frontal sensors during an 800- to 1,800-ms time window and (B) parietal sensors during a 300- to 800-ms time window. Significant differences were found between left and right frontal LPP amplitude and parietal P3/LPP only for negative images in the rumination condition (p < .05).
