What are age related preferences?
Females’ period of fertility: 13-45 years
Males’ period of fertility: 13-65 years

Age at marriage.
Buss found the actual mean age at marriage difference was 2.99 years with men being older.
Why do women prefer older men?
Age is an indicator of status
Males mature sexually later than females
Why do men prefer younger women?
Adult men will value younger mates because women have a narrower window of fertility and men are trying to maximise their reproductive potential.
Why do teenage boys prefer older girls?
Adolescent males prefer women who are a little older because they have already entered the window of greatest fertility.
What about same-sex relationships?
A study of heterosexual and homosexual men
No differences in age preferences for long-term or short-term relationships
Both groups preferred younger age-range for long-term relationships.
If men’s age-preference is related to fertility and reproductive potential - then you would expect heterosexual men to prefer younger women.

- Facial attractiveness
- Body shape
Body shape.
Overall body shape has been studies in terms of waste-to-hip ratio (WHR)

What is the WHR of a healthy pre-menopausal woman?
Between 0.67 and 0.8
What WHR do other cultures prefer?
Indonesia, Afro-American and Caucasian men and women preferred 0.7
Matsigenka men of Peru (free from Western influence) preferred WHR of 0.9
BMI OR WHR?
Swami and Tovee argued BMI, as an indicator of economic status, is much more important than WHR.
Dixon found that 3 remote tribes from papua new guinea responded more strongly to WHR than BMI
What about WHR in males?
Low WHR is indicative of high oestrogen levels
High WHR indicates high levels of testosterone
Men with 0.9 WHR judged by women to look better, be healthier and more intelligent.
Do human babies prefer attractive faces?

What did Langlois and Roggman find?
A face composed of 10 superimposed faces (10 merged faces together on computer) was judged to be more attractive than a face composed of 3.
Are average features attractive?
Thornhill and Gangestad found that protein heterozygosity (an indication of genetic adaptability) is highest in individuals with average traits - average traits are a good indicator of genetic health
Rhodes found that women with average faces had fewer past health problems than women with more distinctive faces
Are symmetrical features attractive?
Perret found that computer generated perfectly symmetrical faces were judged as less attractive than natural faces with a slight asymmetry.
Are feminised female faces more attractive?
