When memory meets beauty: Insights from event-related potentials.

Facial attractiveness plays a key role in human social and affective behavior. To study the time course of the neural processing of attractiveness and its influence on recognition memory we investigated the event-related potentials (ERPs) elicited in an old/new recognition task in response to faces with a neutral expression that, at encoding, were rated for their attractiveness. Highly attractive faces elicited a specific early positive-going component on frontal sites; in addition, with respect to less attractive faces, they elicited larger later components related to structural encoding and recognition memory. All in all, our results show that facial attractiveness, independently from facial expression, modulates face processing throughout all stages from encoding to retrieval.
