Impulsivity and semantic/emotional processing: An examination of the N400 wave

Grand-average event-related potentials (ERPs) for high impulsives (black) and low impulsives (gray).

Grand-average event-related potentials (ERPs) at frontal, central and parietal scalp quadrants for congruent (solid) and incongruent terminal words (dashed) of sentences.

Grand-average event-related potentials (ERPs) at frontal, central and parietal scalp quadrants for negative (dashed), neutral (gray) and positive (solid) emotional terminal words of sentences.

Scatterplot illustrating the relationship between impulsivity and N400 amplitude at fronto-central (FCz) scalp site for emotionally neutral incongruent terminal words of sentences.
