Abstract
The ability to recognise one’s own face is crucial for self-identity formation and it plays a key role in the development of social interactions. Our starting hypothesis was that own-face recognition may be a psychophysiological phenomenon capable of activating the vegetative system in a peculiar manner, via sympathetic pathways. To test this hypothesis we studied the sympathetic skin responses (SSRs) evoked in 18 healthy subjects by the image of their own faces and by six other different visual stimuli. The SSRs were enhanced when participants were shown their own faces. Both SSR area and SSR amplitude contributed to this phenomenon. This work may offer new insights into the psycho- physiological processes involved in own-face recognition; moreover, the SSR could be a useful tool for future studies of patients affected by neuropsychiatric disorders presenting impairment of own-face recognition or representation of self-identity
