what are the two strategies for maximising reproductive success
anisogamy
parental investment
what is anisogomy
differences in male and female sex cells
men, sperm cells produce large quantities, quickly replenished, created continuously
woman’s egg cells are limited in time intervals, production only lasts number of years
consequence is that female are rare resources
what is parental investment
biological differences in genders in parental investment
women carry children, breastfeed
men carry responsibility
consequence is for women if they make a bad decision out of the men, would be left with lack of resources and protection
what are the effects anisogamy and parental investment
they create gender differences in sexual selection
Intra sexual selection and inter sexual selection
what is intra sexual selection
males compete to be chosen by the woman
what is inter sexual selection
females use to select males, choose the best in the pack
what are male preferences (4)
- signs of fertility, big eyes, lips show youth)
- waist to hip ratio of 0.7
- facial symmetry, strong genes
- nurturing signs
what are female preferences (3)
- strength, height ability to protect offspring
- facial symmetry, good genes
- sexy sons hypothesis, choose good looking male to pass genes off to son, so they can be protected and then carry on the genes
what is sexy sons hypothesis
where females choose a good looking male so the trait can be passed onto their son, he can then be selected by a female and genes would continue
what is sexual dimorphism
differences int he characteristics between men and women.
ie strength is desirable for man to compete and protect offspring, more muscular as genes are passed on
women less muscular as they don’t have to compete and not desirable for men
what is self disclosure
theory that relationships are built on trust and you gradually disclose more information to reveal true self
should be reciprocated and it is to gain a between understanding of partner
involves social penetration theory
what is social penetration theory
breadth and depth
onion metaphor
breadth, sharing hobbies, music interest etc
depth, what is off limit, difficult experiences, religion
giving too much info can ruin relationship before it begins
too much- no reciprocation
too little- let them feel you are just friends
what is physical attractiveness
us finding certain features more attractive using evolutionary ideas
ie male- signs of fertility, 0.7 hip, symmetry
female- strength, good genes, symmetry
what is the halo effect
when people are judged in a more positive light than others if they have more positive traits
attractiveness leads to having disproportionate influence on judgements of other atributes
attractive people rated more strong, intelligent, kind and successful and leads to self fulfilling prophecy
what is the matching hypothesis
choosing someone on the same level of attractiveness to avoid rejection, partner compromise
what are the three steps in filter theory
- social demography
- similarity of attitudes
- complementarity
what is social demography
first step of filter theory
social circumstances (ie distance) rules out, socially or culturally similar is desired
education, social class, religious beliefs, gives future reassurance
what is similarity of attitutes
second step of filter theory
sharing same beliefs and values, importance of family and career views
(Bryne) found most important less than 18 months in relationship
discovered in self disclosure for greater intimacy
what is complementarity
the third step of filter theory
partner having traits which the other partner lacks to fulfil each others needs, having traits
what is the idea of social exchange theory
thibault and kelly
rewards- costs = profits
claim partners strive for maxing rewards (ie support, sex)
minimise costs (stress, time, commitment)
aim to be in profit
what is comparison level
how much reward we feel that we deserve
understanding developed on cultural norms and previous relationship expectations (ie books films)
level of comparison level is same level as self esteem (ie high comparison level = high self esteem)
people consider if relationship is worth pursuing after this
what is comparison level for alternatives
people stick to current relationship if more profitable from available alternatives (single, new relationship)
if people consider themselves to be happy they don’t consider alternatives
