Is your own face more than a highly familiar face?
This study aimed to elucidate whether distinct early processes underlie the perception of our own face. Alternatively, self-face perception might rely on the same processes that realize the perception of highly familiar faces. To this end, we recorded EEG activity while participants performed a faci...

Is your own face more than a highly familiar face?Alzueta, ElisabetMelcón, MaríaPoch, ClaudiaCapilla González, AlmudenaSelf-face processingfamiliarityevent-related potential (ERP)N170P200N250PsicologíaThis study aimed to elucidate whether distinct early processes underlie the perception of our own face. Alternatively, self-face perception might rely on the same processes that realize the perception of highly familiar faces. To this end, we recorded EEG activity while participants performed a facial recognition task in which they had to discriminate between their own face, a friend’s face, and an unknown face. We analyzed the event-related potentials (ERPs) to characterize the time course of neural processes involved in different stages of self-face recognition. Our results show that the N170 component was not sensitive to self-face. In contrast, the subsequent P200 component distinguished between self-face and the other faces. Finally, N250 amplitude increased as a function of face familiarity. Overall, our data suggest that self-face recognition neither emerges at the first stage of the encoding of facial information nor at a later stage when familiarity is processed. Rather, the distinctive processing of self-face arises at an intermediate stage (~200 ms), as indicated by a lower P200 amplitude. This could be taken as an indicator that self-face recognition is facilitated by a reduced need for attentional resources.
