The question of whether unconscious processing is involved in the detection of one’s own image has yet to be answered. In recent studies, an automatic shift of at‑ tention toward this stimuli was shown. Here, based on a theoretical framework of bottom up visual selection, we predicted the emergence of N2pc component (neu‑ ral marker of attentional shifts) in conditions where conscious identification of one’s own face was preclud‑ ed. This hypothesis was tested in a dot‑probe paradigm with masked and unmasked pairs of faces (other and self) coupled with electrophysiological (EEG) record‑ ing. The validity of the masking procedure was veri‑ fied by a sensitivity measure (d’), t(17)=1.57, p=0.135, 95% CI=[‑0.07, 0.5], BF=0.68. A clear N2pc was found in both masked (t(17)=‑2.34, p=0.031, 95% CI=[‑0.48, ‑0.03], d=‑0.55, BF=4.07) and unmasked (t(17)=2.91, p=0.01, 95% CI=[‑0.87, ‑0.14], d=‑0.67, BF=10.71) tasks, which indicates automatic allocation of attention towards self‑face in both unconscious and conscious conditions. This supports the notion that the self‑recognition pro‑ cess has a strong unconscious component and sheds new light on the ongoing debate regarding the disso‑ ciative nature of attention and consciousness.
