relationships Flashcards
sexual selection
characteristics and behaviors that increase reproductive success (strength, wide hips) giving an evolutionary advantage, as those having these are more likely to survive and pass on genes responsible
anisogamy
refers to the differences between male and female gametes (sex cells). It is important because it gives rise to differences in the way that males and females select partners to produce with
male gametes
extremely small, highly mobile and do not require a lot of energy to produce
female gametes
large, produced at intervals for a limited number of fertile years and require a huge investment of energy
inter-sexual selection
the way that certain traits increase attractiveness and make it more likely that members of the opposite sex will mate with them
quality over quantity, preffered by females
quality over quality
females optimum mating strategy
to select a genetically fit partner who is able and willing to provide resources
intra sexual selection
refers to the competition between one gender (normally males) to be able to mate with the opposite sex. The winner of the competition can reproduce and pass on to his offspring
quantity over quality
males optimum reproductive strategy
to mate with as many females as possible as minimal effort is required to produce enough sperm to theoretically fertilise every woman on earth
self disclosure
when you gradually reveal personal and intimate information about yourself yo another person which creates feelings of trust and closeness in relationships
social penetration theory
Altman and Taylor
the gradual process of revealing your inner self to someone else, involving the reciprocal exchange of depth and breadth of information
physical attractiveness
an immediate way of selecting potential partners.
e.g. facial symmetry is attractive to males and females because it is an honest signal of genetic fitness and neotenous features are attractive because these trigger a protective instinct in males
halo effect
a bias where we assume attractive people have attractive personalities too
matching hypothesis
Walster
we choose partners who are similar in physical attractiveness to ourselves and to do this we have to make a realistic judgement about our own value to a potential partner
filter theory
Kerkhoff and Davis
we select partners by narrowing down the available options using three filters
social demography
refers to a wide range of factors which influence the chances of potential partners meeting eachother in the first place e.g. proximity, accessibility, social class, levels of education.
this enables the realistic field of potential partners to be much narrower because our choices are constrained by social circumstances.
similarity of attitudes
we find partners who share our basic values attractive in the earlier stages of a relationship, so we tend to discount available individuals who differ from us in their attitude
E.g. partners believing that family is really important
complementarity
when each partner has traits that the other lacks. this makes couples feel like the complete eachother and that they fulfil eachothers needs, which adds depth to a relationship making it more likely to flourish
e.g. one partner has a caring nature and the other likes to be cared for
social exchange
Thibault and Kelley
an economic theory of how relationships form and develop.
It assumes that romantic partners act out of self interest in exchanging rewards and costs and a satisfying and committed relationship is maintained when rewards exceed costs (the minimax principle) and potential alternatives are less attractive than the current relationship
comparison level
the amount of rewards you believe you deserve to get.
It is developed out of experiences of previous relationships and influenced by social norms
linked to self esteem and we will consider if a relationship is worth pursuing on the basis of our CL being high
comparison level for alternatives
predicts that we will stay in out current relationship only so long as we believe it is more rewarding than the alternatives
based on our current relationship and being in a satisfying relationship will mean that you may not notice that alternatives could be available
sampling
we explore the awards and costs of social exchange by experimenting with them in our own relationship or by observing others do so
bargaining stage
this marks the beginning of a relationship when romantic partners start exchanging various rewards and costs, negotiating and identifying what is most profitable
