The self-face captures attention without consciousness: Evidence from the N2pc ERP component analysis.

Area of Science:

• Cognitive Neuroscience
• Social Psychology
• Visual Perception

Background:

• Self-related stimuli, such as one's own name or face, receive preferential processing.
• Key questions remain regarding whether self-prioritization is automatic or controlled, and if it's exclusive to self-related stimuli.

Purpose of the Study:

• Investigate the attentional prioritization mechanism of self-face images.
• Determine if self-prioritization operates automatically during early processing stages.
• Examine if visual familiarity with a face can elicit similar attentional capture as self-faces.

Main Methods:

• Utilized a dot-probe experiment to assess attentional capture.
• Employed backwards masking to isolate early, preconscious processing stages.
• Analyzed the N2pc event-related potential (ERP) component to measure attentional allocation.

Main Results:

• The self-face image automatically captured attention, irrespective of conscious or unconscious processing.
• Visually familiar faces did not attract attention, under either conscious or unconscious conditions.
• N2pc component analysis confirmed early and automatic attentional capture by self-faces.

Conclusions:

• The self-prioritization mechanism is early, automatic, and not solely driven by visual familiarity.
• Results support efficient unconscious processing of faces.
• Demonstrated a dissociation between attention and consciousness in self-prioritization.
