Stylized faces enhance ERP features used for the detection of emotional responses

Published in Frontiers in Human Neuroscience, 2023

It is found that artificially enhanced human faces with exaggerated, cartoonish visual features significantly improve some commonly used neural correlates of emotion as measured by event-related potentials (ERPs).
