Their description: The study investigates the relationship between apparent traits in male faces and attractiveness. Women’s choices vary substantially when considering a partner and we would like to understand some of the factors that influence these differences. The whole experiment will last approximately 15 minutes and is intended for female participants only. The study is being conducted as part of the researchers’ master project for the School of Psychology, University of St Andrews. You will be asked to select which face is more attractive on an interactive that allows you to dial up or dial down a specific characteristic. You will also be asked to complete a questionnaire that asks about your sex, age, sexual orientation, personal beliefs, attitudes towards sex, self-rated attractiveness and personality questions on development and personal relationships.
