Cortical N400-potentials generated by adults in response to semantic incongruities

• Eight adult participants were investigated in a pre-experiment for the future assessment of semantic N400 effects in children. The materials were words resented in semantically incongruent vs. congruent picture contexts. For example, he word duck was played while a picture of a tree was shown in the incongruent est condition vs. the word duck was played while a picture of a duck was shown in the congruent test condition. A larger N400 effect was expected in response to the incongruent audio-visual pairings. The results showed in time extended peak-to peak differences between congruent and incongruent audio-visual pairings at the centroparietal, parietal and parieto-occipital recording sites. This study was performed to validate the current materials to be used to answer questions on appearance of the N400 component in children.
