Visual attention during the evaluation of facial attractiveness is influenced by facial angles and smile

摘要

Objective: To examine the changes in visual attention influenced by facial angles and smile during the evaluation of facial attractiveness. Materials and Methods: Thirty-three young adults were asked to rate the overall facial attractiveness (task 1 and 3) or to select the most attractive face (task 2) by looking at multiple panel stimuli consisting of 0°, 15°, 30°, 45°, 60°, and 90° rotated facial photos with or without a smile for three model face photos and a self-photo (self-face). Eye gaze and fixation time (FT) were monitored by the eye-tracking device during the performance. Participants were asked to fill out a subjective questionnaire asking, “Which face was primarily looked at when evaluating facial attractiveness?” Results: When rating the overall facial attractiveness (task 1) for model faces, FT was highest for the 0° face and lowest for the 90° face regardless of the smile (P P P Conclusions: Laterally rotated faces and presence of a smile highly influence visual attention during the evaluation of facial esthetics.
