  1. Buss (1989) Sex Differences in human mate preferences

  2. Context • Darwin- suggested mate selection was a matter of evolution (reproduction/ survival of one’s genes). • Evolutionary psychologists believe mate selection can be affected by instincts maximising our chances of reproducing. • Buss was interested in 3 of these instincts: • Parental investment- Trivers (1972) women should favour ambitious, hardworking and rich men. Women invest more into child rearing (pregnancy/ typically the primary caregiver) than men and are thus fussier in choosing a partner. • Reproductive value- Access to fertile females is the main factor affecting male reproduction. • Men will favour young women as female fertility peaks in late teens/ early twenties. • Facial appearance gives cues as to age. Therefore, men will favour facial attractiveness. • Paternal probability- want to be certain we pass on our genes. • Men value chastity more.

  3. Aim Do parental investment, reproductive value, and paternal probability hold true across cultures- if so, they are likely to be a result of evolution.

  4. Procedure- Sample • 37 samples from 33 countries across 6 continents… • In cases where countries had more than one separate population (Israel, Canada, S.Africa) a sample was taken from each population. • In Canada a sample was taken from the French-speaking and English-speaking populations. • 10,047 participants • 4601 male, 5446 female • Avg. age: 23.05 • Sampling method: • Opportunity • Student samples, people applying for marriage licenses (Estonia), secondary-age schoolchildren (New Zealand) • Self-selecting • Responders to a newspaper advert (Germany).

  5. Procedure- Measure/ DV • 2 questionnaires in native language • Questionnaire on factors affecting mate choice • Filler questions disguise the aim of the experiment. • Target variables of age, attractiveness, good financial prospects, chastity, ambition, industriousness, and no previous sexual experience. • Rating scale: • Questionnaire ranking factors affecting mate choice
