relationships Flashcards
according to the evolutionary approach, what are partner preferences driven by
sexual selection
what do males and females choose their partners for
to maximise their chances of reproductive success
how do male gamete’s work
reproduce quickly with little energy expenditure
how do female gametes work
-less plentiful and require lots of energy to produce
what is the difference in m and f reproduction called
anisogamy
what type of partner selection do males use
intra sexual selection
what type of partner selection do females use
inter sexual selection
what is intra sexual selection
where members of one sex (usually male) compete with one another for access to the other sex
what is male-female dimorphism
the accentuation of secondary sexual characteristics in those with greater reproductive fitness
what is the male’s best evolutionary strategy
- have as many partners as possible
- compete with other males to present themselves as most attractive mate to fertile females
what is mate guarding
when males guard their female partner to prevent them from mating with anyone else
what is cuckoldry
when a man raises another man’s child
what is inter sexual selection
where members of one sex (usually female) choose from available prospective mates according to attractiveness
what does anisogamy suggest about women
their best strategy is to be selective when choosing partner
what do females tend to seek for in a male and why
- physical health, high status, resources
- so male can protect them and provide for children
what do women look for in modern society
occupation, social class, wealth
what are the strengths of evolutionary explanations of partner preferences
+BUSS conducted survey of over 10,000 adults in 33 countries. found that females reported valuing resource based characterises. men preferred young, and good looks
+study: students asked to approach opposite sex students and ask them to either: go on date, go to their apartment or go to bed with them. 50% both agreed to date, 75% men agreed to bed. 0% women agreed to bed
what are the limitations of evolutionary explanations of partner preferences
- determinist, we have little free will in partner choice.
- socially sensitive and promote sexist views. women are now more career driven and do not look for resources as much. availability of contraception means that evolutionary pressures are less relevant.
- doesn’t explain other type of relationships: homosexual, arranged marriage
