The influence of age of the face and the waist to hip ratio on judgements of female attractiveness and traits

Various studies have established that the waist to hip ratio (WHR) influences perceptions of female attractiveness. The present study investigated the assumption that ageing of the face will exert a greater influence than WHR in ratings of female attractiveness, when WHR in females is manipulated within the normal range (0.67–0.85). In a within subjects design, 100 participants (mean age 23.4 years) rated 27 photographs on the following scales: youthfulness, attractiveness, fertility, healthiness, fecundity (likelihood of being pregnant), attractive to the opposite sex, a good mother and sexiness. The photographs had been digitally manipulated in terms of three levels of age of the face (young, middle, older: range around 20–40 years) and three levels of WHR (low, medium, high). Regressional analyses indicated that although WHR was found to have a significant influence on all the above attributes, the age of the face was found to have a greater effect. Results are interpreted in terms of age being a sexually selected trait providing potential mates with information concerning phenotypic and genetic quality.
