In event-related potentials (ERPs) studies, recognition memory is associated with two
positivities: one over parietal regions, and one over frontal regions. With nameable neutral
stimuli, such as words or common objects, the parietal effect is usually left lateralized, and
the frontal effect is usually right lateralized. We investigated the lateralization of these effects
for nonnameable emotional stimuli: unfamiliar faces with happy and neutral expressions.
The parietal effect was bilateral, suggesting that the left lateralization of this effect in studies …
