RELATIONSHIPS Flashcards
define evolution
each thing has a set of characteristics which is encoded by genes, the offspring receives this during reproduction
therefore the variation between organisms is the difference in genotypes
3 main steps in evolution
to live to reproductive age
to mate successfully
to ensure offspring survival
whats natural selection
the ability to survive in a specific environment
whats sexual selection
the ability to attract and reproduce, the attributes and behaviours that inc reproductivity are passed onto future generations
whats anisogamy
the difference between male and female cells
male- continuous and cheap
f- produce in intervals and limited for no of years+ expensive
female is rare- 2 mating strategies
whats inter sexual selection and whats the female preference
selection of mates between sexes eg: strategies female use to attract
female- quality over quantity as they want the best for their offspring
what is the male preference within inter sexual selection
reproductive success, they aim to reproduce a lot and usually go for a large hip to waist ratio which reflects ability to reproduce
whats the impact of inter sexual selection
females become more choosy as they want the best for their offspring ( sexy sons hypothesis )
whats intra sexual selection
the selection of mates within sexes eg: males compete with other males for female access
what do males go for within intra sexual selection
quantity, they want to compete for female access as sperm is plentiful “ the winners “ pass on traits
whats the impact of intra sexual selection
dimorphism, males have exaggerated characteristics to become attractive however a weakness of this is that it also attracts predators
strength of evolutionary explanation
review of lonley hearts study found males go for young women and males go for professional and wealthy
SUPPORTS EVOLUTIONARY THEORY
strength 2 of evolutionary explanation
a study was completed where students were i asked ‘ i find you attractive, would you go to bed w me’
0% women
75% males
supports f is choosy and m have evolved a strategy to reproduce
weakness of evolutionary explanation
buss claims sexual selection theory is too simplistic as it states different strategies used for different sexes
buss suggests the same strategy is used when looking for long term partners
SUGGESTS OVER SIMPLISTIC AND PROPOSES A MORE COMPLEX THEORY WHICH CONSIDERS CONTEXT
weakness 2 of evolutionary theory
partner preferences have been influenced by changing social norms and culture
eg: contraception, changing workplace roles
partner preference no longer resource orientated
EE DOESN’T CONSIDER CULTURE BOTH, limited
define physical attraction
assumes we seek to form relationships with most attractive
whats the evolutionary explanation within physical attractiveness
attraction is result of sexual evolution, using attractions as a symbol of genetic fitness
what was the study of evolutionary explanation within physical attractiveness
Shackleford: found people w symmetrical faces attractive. Baby face features eg: big eyes, small nose to represent caring feauture
strength of evolutionary explanation within physical attractiveness
research support
found women w big eyes and large nose were rated as attracted across white, asian and hispanic
features consistent across cultures
whats the halo effect within physical attractiveness
people who are seen as attractive are seen in a positive light
Dion found people who were kind sociable and successful were attractive when compared to others
strength of halo effect
research support.
found attractive politically education and competent.
supports theory but raises the question of if we chose politics based of suitability or attractiveness
whats the matching hypothesis
we look for partners that are on a similar level of attractiveness to what we think of ourselves
strength of matching
feingold research support
meta analysed 17 studies of rl couples and found correlation between partners attractiveness, supports
weakness of matching hypothesis
walsters computer dance
students invited and matched up w partners
secretly judged by panel
during intervals and 4-6m later partners were asked if they wanted a second date and if they found partner attractive.
found higher appreciation of partners than themselves
define self disclosure
revealing personal information and true self to partner, even dark secrets to become more intimate due to more disclosure
whats the social penetration theory
the sp theory suggests we gradually reveals emotion.
reciprocal sharing of experiences. people develop a greater understanding of each other and trust increases
who suggests the onion metaphor and what is it
altman and taylor
self disclosure is a process of removing layers
whats breadth and depth
breadth is the outer layer of self disclosure, the low level risk information
depth is the deep information, which increases self disclosure
whats reciprocity within self disclosure
shaver stated for a relationship to develop, there needs to be reciprocity
a balance in sp inc intimacy
whats depenetration
dissatisfied partners share less until disengaged
strength of self disclosure
research support
strong correlation between satisfication and sd, men and women who use sd and reciprocity were more committed. supports
however only correlation
strength 2 of self disclosure
in depth research .
57% homosexual men and women rely on sd as maintenance, couples w less communication are enc to use .
supports and in depth
weakness of self disclosure
cultural variations.
people in us sd more than china and there is no difference in satisfaction.
sd may be accurate in individualistic not collectivist
weakness 2 self disclosure
contradicting research .
sp claims sd is associated with higher satisfaction however when a relationship breaks, partners disclose more and often, but this doesn’t save the relationship.
contradicts theory
whats the filter theory
an explanation of attraction that states a series of factors that limit the range of desirables
who compared attitudes between long term and short term relationships in student couples
kerchoff and davis
1st filter- social demography
influence chance of meeting
eg: age, location
anyone too different gets filtered
meaningful encounters w those physically close
2nd filter- similarity
share basic beliefs for couples less than 18 months
promotes communication and growth
