| Abstract(in English) | Average face, a superimposed face of a dozen of face pictures, is known to be very attractive for peoples where averageness on facial features is thought to work as clues for healthiness and physical development of the person. In line with that, a perceptually discriminant model using a‘ face-space ’hypothesized that a face stereo- type acquired through lifelong experience is located at the center of face-space and defines the most attractive face. However, as some reports demonstrated the existence of faces more attractive than average face, the estimation of the center of a personally organized face-space is a fundamentally difficult problem. In this study, we hypothesized that the center of a personally organized face-space can be estimated by an average face modified by features of self-face of the person. We conducted two experiments using a set of face pictures morphed from average face to self-face and opposite-self-face of individual subjects. In Experiment 1, we performed a subjective evaluation test of attractiveness of the morphed faces and found that a 15% opposite face was the most attractive. In Experiment 2, by using face aftereffects, we examined which morphed face was nearest to the center of individual face-space. Again, the 15% opposite face was found to be the nearest to the center of individual face-space. These results demonstrate that the 15% opposite face can give the better estimate of the center of individual face-space than average face. It is further suggested the importance of the usage of self-face in the estimation of personally organized face-space that may be essential for the understanding of our personality and social behaviors. |
