relationships Flashcards
sexual selection
evolutionary explanation of partner preference. characteristics which aid reproductive success are passed on and may become exaggerated over generations.
human reproductive behaviour
any behaviours which relate to opportunities to reproduce and thereby increase the survival chance of our genes. it includes the evolutionary mechanisms underlying our partner preferences such as mate choice and mate competition.
anisogamy
the difference between male and female sex gametes.
Males = extremely small, highly mobile, infinite
Females = large, immobile finite
gives rise to two different mating strategies
inter-sexual selection
the female mating strategy.
because female gametes are rarer and finite they must be more selective when choosing a mate because they provide greater effort before during and after birth.
they look for quality over quantity
intra-sexual selection
the male mating strategy
the ‘winner’ gets to pass on his genes to another generation.
it also encourages aggression as competition between males in order to protect their mate from other males.
evaluation of sexual selection
Buss carried out a survey of over 10,000 adults and 33 countries, asking questions related to age and attributes that evolutionary theory predicts are important. females valued resources, males valued looks.
would you like to go to bed study. 75% of men said yes, 0 women said yes.
studies often ignore social and cultural differences Bereczkei argues that women no longer need to be ‘rescued’. Chung analysed partner preferences over 25 years and some had changed and others hadn’t
self disclosure
revealing personal information about yourself. romantic partners reveal more about their lives as the relationship develops. self disclosure can strengthen a relationship.
social penetration theory
Altman and Taylor relationships develop through a gradual process of revealing yourself. giving away your self, thoughts and feelings
reciprocity of self disclosure
mutual or two-way exchange of info which is crucial to success of self disclosure
breadth and depth of self disclosure
is important because moving from breadth conversation to deep conversation marks milestones in the relationship
evaluation of self disclosure
sprecher and hendrick - men and women who used reciprocal self disclosure were more satisfied with their relationship
RLA - hass and staford found SD of 57% in gay couples. can be used in couples therapy
cultural bias - US SD more than china
shackleford and Larsen - physical attractiveness
related to symmetry
neotenous faces
physical attractiveness is a sign of strong genes
important beyond formation - about 7 years
the halo effect
how one distinguishing feature, in this case attractiveness, can have a disproportionate effect on our judgement of other people.
Dion et al found attractive people are consistently rates as kind, strong, sociable and successful
matching hypothesis
while we would all desire the most physically attractive and genetically strong partner we cannot. so, we select partners who match our own perception of our looks
evaluation of physical attractiveness
RS for halo effect - Palmer and peterson - politics and competent
individual differences - High (did care) VS low (didn’t care) MACHO scale
mixed support for matching hypothesis - meta analysis of 17 studies showed varies in matching between real participants
filter theory
states that a series of different factors limits the range of available romantic partners
social demography
proximity, social class, education ETC
similarity in attitudes
sharing beliefs and values in the early stages of a relationship (18 months)
complementarity
do partners meet each others needs. they have characteristics that the other lacks. important long term
evaluation of filter theory
RS - winch similarity is needed early on but complementarity is needed long tern
lack of replication of original findings - social change and insufficient measurement into depth
direction of effect between similarity and attractiveness - emotional convergence
lacks temporal validity - changing attitudes to dating
social exchange theory
how relationships form and develop. partners act out of self interest, measuring cost and reward. it also considers alternative options.
the minimax principle
minimise losses and maximise gains
profit
cost minus rewards
