RELATIONSHIPS Flashcards
sexual selection
a type of natural selection (partner preference). Attributes or behaviours that increase reproductive success are passed on to aid reproductive success drive evolution
anisogamy
the difference between male and female sex cells.
male gamete
sperm - doesnt require much energy, vast numbers, lifetime
female gamete
ova/egg cells - large, produced at intervals, limited no. of fertile years
inter-sexual selection
between the sexes - strategies that a male uses to select a female or visa versa (women = quality, fit,height)
studies that support inter-sexual selection
Trivers(1972) - female makes greater investment so chosy as concequences of the wrong choice worse for female. Both chosy as lose invest rescources.
sexy sons hypothesis
Refers to when a female mates with a male who has a desirable characteristic, this ‘sexy’ trait is inherited by her son. Increases the likelihood that succeessive generaions of females will mate with her offspring
what is intra-sexual selection
within each sex - the strategies used between makes to be the one selected ( males seek quantity, unlimited sperm. Compete for fertile females)
EX. FOR PP - RS FOR INTER-SEXUAL SELECTION
-75% of men agreed to sexual request from women, 0% of women agreed to males request (Clark et al 1989)
- supports view (women choiser)
EX. FOR PP - RS FOR INTRA
- 10,000 adults questioned in 33 countries, men seek signs of reproductive capacity (youth), women want resources (Buss 1989)
- consistent sex differences, predictions right
EX. FOR PP - SOCIAL + CULTURAL INFLUENCES UNDERESTIMATED
- Rapid changes in partner preferences due to changing social norms like contraception etc (Bercezkei 1997)
- pp today are an outcome of evolutionary + cultural influences. Theory doesnt account for that = limited
self-disclosure
revealing personal information about yourself.
In relationships partners reveal more about their true selves as relationship develops, can strengthen relationship when used appropriately.
describe the social penetration theory
Altman + Taylor’s (1973) - how relationships develop. Gradually reveal your inner self to someone else (deepest thoughts + feelings).
involves RECIPROCAL EXCHANGE of information between intimate partners.
This displays trust for the relaionship to go further other person must also reveal sensitive info.
explain breadth + depth
We disclose superficial (low risk) info at the start of a relationship as too much info can put relationship in jepordy before it has developed. As it develops self disclosure becomes deeper leading to high risk info coming out as relationship progresses (true self revealed)
what is reciprocity of self-disclosure
disclosure must be returned, not just breadth + depth (REIS+SHAVER 1988)
Balance of self disclosure between partners increases intimacy + deepens relationship
AO3:SD - RESEAECH SUPPORT
- positive correlation between satisfaction + self disclosure (Sprecher+Hendrick), especially when partners take turns
- support findings so increases validity of theory
AO3:SD- REAL WORLD APPLCATION
- 57% of homosexual men + women said they use self-disclosure as maintainance stratergy, a skill that can be learnt (Haas + Stafford)
- shows psychological insight can be valuable in helping people who are having problems with their relationship
AO3:SD- CULTRAL DIFFERENCES
- less sexual self-disclosure in collectivist cultures abt sexual thoughts but experience the same satisfaction (Tang - US v China)
- based on findings from western cultures = not generalisable to other cultures
why is physical attractiveness so important?
symmetrical face is attractive because its an honest sign of genetic fitness. Baby faces are (wide eyes) trigger caring instinct (Larsen) both naturally selected
what is the halo effect
we have positive stereotypes of physically attractive ppl + assume they possess other positive characteristics (Dion et al)
what is the matching hypothesis
Walster + Walster 1969 - suggests we look for partners who are a similar level of attractiveness to us instead of choosing more attractive ppl
what was the procedure of the matching hypothesis
computer dance study (paired ppl up) - no support as chose most attractive (Walster et al) but supported by Berscheid et al replicated study but ppts chose partners (chose similar lvl of attractiveness)
AO3: PA - RS FOR HALO EFFECT
- Palmer + Peterson (2012) attractive ppl rated more politically competent, implications for poitics
- suggests there are dangers for democracy if politicans are judged based off looks
AO3: PA - EVOLUTIONARY EXPLAINATION
- some female features (small nose/large eyes) considered attractive across all cultures, sexual selection (Cunningham 1995)
- the importance of pa makes sense at an evolutionary lvl
