Effects of recent word exposure on emotion-word Stroop interference: An ERP study

►Prior word exposure increased RT interference during an emotion-word Stroop task. ►This was independent of emotional content of the word. ►P290, N400 and LPP were more positive-going to negative than to neutral words. ►For unexposed words, RT interference correlated with P290, N400 and LPP emotion effects. ►Better early and late attentional processing of task-irrelevant emotion words.
