顔加工アプリによる若返りおよび性別変換が自己・他者の顔画像の魅力に与える影響

Abstract

This research was conducted to investigate the influence of the gender swap and rejuvenation conversion by the face editing app on the facial attractiveness. In this research, the face images of participants themselves and others were used as the original images. They were edited using a face editing app to swap their gender and rejuvenate their age, resulting in 10 versions of images that were created as experimental stimuli (gender swap: original, swapped; rejuvenation level: 5 levels). Participants evaluated attractiveness of the entire face and specific parts of the face, as well as shape of parts of the face by using 7-point grading scale. The results showed that as the rejuvenation conversion level increased, the eyes basically became bigger, the skin became brighter, and the attractiveness of entire face became higher. Furthermore, the effects of male-to-female gender swaps were not always symmetric with those of femaleto-male gender swaps. This suggests that an increase in attractiveness resulting from a male-to-female gender swap does not necessarily mean a decrease in attractiveness from a female-to-male gender swap. These results indicate that gender swap process of the face editing app might be different between the genders of the original face image.
