relationships Flashcards
what is sexual selection
survival of the sexiest
if particular characteristic becomes established as universal preference amongst females then males who possess it strongest = greatest reproductive success
selective pressure to have characteristics
what is anisogamy
differences in reproductive ability of sperm/ova (gametes)
males= no shortage of fertile males
females= rare resource
what is inter- sexual selection
females quality over quantity
more choosy as more consequences of choosing wrong partner as choices determine characteristics passed down
what did trivers 1972 suggest about inter sexual selection
females make greater investment of time, commitment and other resources before, during and after birth of offspring
what did Fisher suggest in 1930
sexy sons hypothesis
genes enhanced for reproductive success
choosing partners due to what they want their offspring to look like (predicting offspring)
what is intra sexual selection
choosing quantity over quality (males)
competition between males to be selected
victor gets characteristic passed down to next generation
what has intra sexual selection given rise to
dimorphism = two forms
males and females end up looking very different
e.g. for females youthfulness is targeted
problem for males as characteristics in order to compete strengthen= males then need to over compete for female
what is self-disclosure
revealing personal info about yourself
what did altman and taylor 1973 suggest
social penetration theory
what is social penetration theory
gradual process of revealing inner self to people, eventually giving away deepest thoughts and feelings
reciprocal in romantic relations
allows a building of trust
more disclosed = the more penetration
what did altman and taylor suggest about the breadth and depth of self disclosure
two elements to increase partner commitment:
low- risk info= surface level info (acquaintances/ co-workers)
TMI= too much info, which may threaten relationship
therefore need to be gradual reveal
what did reis and shaver 1988 suggest
for relations breadth and depth to increase there needs to be a reciprocal element to relation
what did sprecher and hendrick 2004 find when evaluating self disclosure theory
research support
several predictions about self disclosure supported
studied heterosexual dating couples
found strong correlation between measures of satisfaction and self disclosure for both partners
relationships in reciprocity are closer and more satisfied
increase validity
what did haas and stafford evaluate about self disclosure theory
real world application
can help people who want to improve relationship
romantic partners deliberately use self disclosure to increase intimacy
57% heterosexual partners suggest self disclosure= increased their partner intimacy
what did tang 2013 suggest about the cultural limitations of self disclosure theory
not true for all cultures
collectivist = little self disclosure but present the same levels of satisfaction to individualist= high self disclosure
what is filter theory
explanation for relationship forming
series of progressive factors that reduces the range of available romantic partners
who identified filter theory
kerckhoff and davis 1962
what did kerckhoff and davis do
compared attitudes and personalities of student couples in short term= less than 18 months and long term relationships
what were the three main factors for filter theory
social demography
similarities in attitudes
complementarity
describe social demography
features that describe a population, e.g. location or class
outcome of this filter= homogamy = more likely to form a relationship with someone socially or culturally similar
describe similarities in attitudes
only important for first 18 months of relation
narrower field of availables
a need for partners in earlier stages to agree over basic values- things that really matter to them
promotes self disclosure and encourages greater communication
describe complementarity
ability to meet each others needs
two partners complement each other through traits the other lacks
important for long term relations
attractive as it makes them feel whole together
what are the problems with complementarity
may not be central to all long term relations
Markey et al 2013
found that lesbian couples of equal dominance= most satisfied
relation last= 4 1/2 years
why does social change limit the filter theory
first filter can be made easier or changed due to dating apps widening the scope for availables
