Visual attention is easily captured by peripheral faces particularly high attractive ones or threat-related ones although they present as completely task-irrelevant distractors. Several neuroimaging studies reported that the beauty and the ugly stimuli activated the emotional brain network or the social reward related areas such as orbitofrontal cortex, premotor cortex or basal ganglia. The function of these networks is thought to be related to attention capture by emotionally valuable faces. However, little is known that the mechanisms for ugly or beauty faces capture of attention involuntarily. The study employed RSVP task and measure event-related potentials (ERPs) to test how the task-irrelevant ugly/beauty faces capture attention. We use artificial faces (beauty and ugly) for distractor stimuli which were made by using classification image paradigm (Naito et al., 2017) to control the level of ugliness and attractiveness (beautifulness). Forty-one participants for behavioral study and twenty participants for ERP study. In each task trial, 20 letters with variable colors were presented rapid serially at the center of the monitor in every 100 ms. Participants were asked to detect target color letter ignoring the peripheral distractor stimulus. The results showed that the rate of correct target detection significantly decreased when ugly face presented as a distractor. N2pc peak amplitude enhanced ugly and beauty distractor condition compare to control condition, also, LPC (late parietal positivity) decreased in ugly condition. These results suggest that emotional valuable face could capture attention before aesthetic perception.
