Processing gender agreement errors in pleasant and unpleasant words: An ERP study at the sentence level.

In this study we examine the extent to which aspects such as the emotionality coded in words may interfere with the processing of gender agreement errors in a sentence grammaticality judgement task. We follow the methodological pattern of our previous experiments, using consistently the same kind of structure and task (gender agreement) and only emotional (pleasant vs unpleasant) words, in an attempt to clarify whether neural correlates and performance show similar patterns in positive and negative words. We found an emotional effect in the N400 time window for unpleasant adjectives as well as the classic grammaticality effects in the left anterior negativity (LAN) and the P600 components. Overall, our results confirm those of our previous studies in that the LAN and the P600 grammaticality effects are not influenced by the emotional valence of moderately arousing pleasant and unpleasant words, showing that during sentence reading morphosyntactic error detection seems to be encapsulated.
