We examined behavioral and electrophysiological indices of self-referential and valence processing during a Self-Referential Encoding Task in 9- to 12-year-old children, followed by surprise memory tasks for self- and other-referential trait adjectives. Participants endorsed more positive than negative self-referential information but equally endorsed positive and negative information about the other character. Children demonstrated enhanced parietal LPP amplitudes in response to self- compared to other-referential trait adjectives. Positive and negative information was differentially remembered depending on the order of the referent cues presented, suggesting that social information undergoes differential consolidation processes depending on the referent and the order of presentation.
