The present study is one of the first to incorporate both behavioral data and EEG data in a native Dutch noun phrase production task to investigate the processing of grammatical gender. We used a picture-word interference paradigm in which speakers had to name a picture while being distracted by a superimposed word. The distractors were manipulated for grammatical gender congruency with and semantic relatedness to the picture names. In separate blocks, participants had to produce either bare nouns, or determiner noun constructions. We found a robust effect of the semantic relatedness effect in the behavioral data, in which targets belonging to the same semantic category as the distractor were named significantly later than unrelated targets. The EEG data on the semantic relatedness effect were less clear, possibly due to opposing ERP components in (partly) overlapping time windows. More importantly, we replicated the gender congruency effect in reaction times, showing that naming latencies were longer for gender-incongruent trials than for congruent trials. This behavioral effect disappeared in bare noun naming. The EEG data showed similar results, in which a more positive peak was found between 385-585 milliseconds for incongruent than for congruent trials, again only in the determiner noun block. The result seems to indicate a P300 effect rather than the expected enhanced N400, suggesting higher conflict resolution processes for incongruent trials. The absence of the gender effect in bare noun naming in both data types suggests that grammatical gender is not automatically accessed or selected in Dutch noun (phrase) production. This in turn has implications for speech production models.Show less
