Electrophysiologic potentials (average evoked potentials (AEP) and contingent negative variation (CNV)) recorded during simple recognition and discriminative responses to tachistoscopically presented letter‐pair stimuli showed a systematic shift toward greater overall positivity (i.e., smaller CNVs and larger late positive components) during increased processing load. In addition, more positive P2 components were found in the right as compared to the left hemisphere during simple recognition, and this asymmetry was enhanced during the more complex processing condition.
