Abstract:

Using eye tracking technology, investigate the effect of subliminal repeated exposure on facial preference and the moderating effect of facial attractiveness. It is found that: (1) With the increase of subliminal exposure times, the preference proportion of faces increased, the first fixation time of individuals viewing faces decreases, the total fixation time increases, and the pupil diameter shortens; (2) Facial attractiveness plays a moderating role between subliminal repeated exposure and facial preference, specifically manifested as the proportion of preferences for high and low attractiveness faces increasing linearly with the increase of subliminal exposure times, while moderate attractive faces show an inverted U-shaped trend with the increase of subliminal exposure times. These results explored the impact of bottom-up visual stimuli on facial preferences from a subliminal exposure perspective, expanding the dual pathway model of facial processing.
