This study investigated attractiveness ratings of individual faces and facial prototypes while controlling for symmetry. Symmetry was controlled by comparing symmetric individual faces to prototypes composed of 2, 4, 8, and 16 symmetric faces, morphed together by blending facial features such as eyes, nose, eyebrows, mouth, and outer contour. Adult male and female participants (N = 139, M age = 19.12 years) viewed stimuli presented on a computer monitor and rated the attractiveness of each facial stimuli on a 10 point scale, with higher values representing increased attractiveness. Results indicated that attractiveness ratings increased as the number of faces in the prototype increased, F(4,104) = 145.24,p<.0005. Since symmetry was controlled in this study, other factors must contribute to a prototype's attractiveness.
