Abstract
Memorizing emotional stimuli in a preferential way seems to be one of the adaptive strategies brought on
by evolution for supporting survival. However, there is a lack of electrophysiological evidence on this bias
in working memory. The present study analyzed the influence of emotion on the updating component of
working memory. Behavioral and electrophysiological indices were measured from a 3-back task using
negative, neutral, and positive faces. Electrophysiological data evidenced an emotional influence on the
working memory sensitive P3 component, which presented larger amplitudes for negative matching
faces compared to neutral ones. This effect originated in the superior parietal cortex, previously reported
to be involved in N-back tasks. Additionally, P3 results showed a correlation with reaction times, where
higher amplitudes were associated with faster responses for negative matching faces. These findings
indicate that electrophysiological measures seem to be very suitable indices of the emotional influence
on working memory
