What is sexual selection?
Some characteristics are successful in aiding reproduction, may not be advantageous but for survival but can help attract a parter, which encourages mating
What is anisogamy?
Refers to the difference between male and female sex cells (gametes)
Other sex will compete for the sex who invests the most - becomes a limiting resource
Males produce many sperm, small in size, energetically cheap
Females produce few eggs, large in size, energetically expensive
Thus females are more picky in her choice of a mate
What is inter-sexual selection?
Between sexes, strategies that males or females select one another from = competition
What is intra-sexual selection?
Within each sex, strategies between males to be the one that is selected
What is dimorphism?
The obvious differences between males and females
Evaluation for evolutionary explanation
+ Buss
10000 people
37 cultures
Found females look for resources, financial stability, ambition = evolutionary advantage is it supports a better quality of life for child
Found males look for youth and physical attractiveness = evolutionary advantage is that they are more likely to have children
+ Clark and Hatfield
approached strangers at uni campus
asked 3 questions = would you go on date with me (50% males, 56% females said yes, would you go back to my apartment (69% males, 6% females), would you have sex with me (75% males, 0% females)
Found females were more likely to go on a date, but males were more likely to go back to an apartment or have sex
Supports the idea that males are looking to spread genes, females looking for resources and commitment
- Does not explain homosexual partner preferences
+ males look for hip to waist ratio of 0.7
shows signs of fertility
attractive because it is an honest signal that the women is fertile but not currently pregnant
What are the three factors affecting attraction?
- Self - disclosure
- Physical attractiveness
- Filter theory
What is self disclosure?
Revealing personal information about yourself, tends to get deeper and more frequent as relationships develop, can strengthen romantic bond when used appropriately
What is the social penetration theory?
Altman and Taylor
as each person reveals more personal information about themselves it displays trust to the other person
as each partner reveals more they get deeper and deeper
- Superficial communication
- Building trust
- Strong working relationship
Breadth and Depth
Levels = superficial, intimate, personal, core
Needs reciprocity
Evaluation of the factors affecting attraction - self disclosure
+ Sprecher and Hendrick
studied heterosexual couples
found strong correlation between amount of self disclosure and measures of the quality of the relationship
- correlation does not equal causation
happier relationships may disclose more - Generally thought females are better communicators = example of alpha bias, exaggerating the differences between men and women
- does not take into account cultural differences - self disclosure may not always lead to more intimate relationships
research in China and USA - high self disclosure found in breakdown stage of relationship = does not always mean satisfaction levels are high
What factors make people attractive?
- Symmetrical faces
- Baby faces
What is the halo affect?
People who are attractive are seen as having more positive personality traits
What is the matching hypothesis?
- look for partner on similar level of attractiveness
- avoid pain of rejection by not chasing partners we see as too attractive
- retain partners by not choosing someone who will leave us for someone else
- realistically appraise out attractiveness compared to others
What is the computer dance study?
Walster
752 students
- when ticket bought, told that personal information given would be fed to computer to find ‘ideal match’ date
- in fact they were randomly assigned
- observer marked them on attractiveness
- students asked how much they liked partner after date
Found most liked partners were the most attractive ones - not ones that matched own level of attractiveness
Contradicts matching hypothesis as people did not prefer those who were similar to themselves
Evaluation for the matching hypothesis
+ physically attractive people were rated as more politically knowledgeable and competent
- dating apps show people go for others more attractive than themselves
suggests that people are always looking to do better than how they rate themselves
+ dating sites may not be used to actually select a long term partner
- individual differences
high score on macho scale = physical attractiveness more important
low score on macho scale = physical attractiveness less important - methodological issue = subjective, based off individual preferences
What is filter theory?
Kerchkoff and Davis
- how romantic relationships form and develop
- three main factors we use to narrow down our range of partners to a field of desirable
1. Social demography = more likely to come into contact with people who live in our area (proximity filter)
2. Similarity in atitudes = due to social demography, more likely to come into contact with people with similar core values
(Kerchkoff and davies = only important in first 18 months)
3. Complementarity = attracted to people who can meet/fulfil each others needs, partners complement each other when they have the traits that the other lacks
(Kerchkoff and Davies found this was more important for long term couples)
Evaluation for filter theory
- dating apps remove the first filter
allows an increased area of people for you to meet - 70 lesbian couples
4.5 average years together
valued similarity which goes against complementarity - third stage of filter theory
+ similarity in values valued in less than 18 month couples, complementarity valued in more than 18 month couples
- assumes that relationships after 18 months are long term/committed
some cultures commit to marriage before 18 months (long term relationship)
What is social exchange theory?
Thibault and Kelley
Economic theory
involves constant exchange of resources
trying to maximise rewards and limit costs
relationships will fail if not profitable
relationships have opportunity costs - investment of resources cannot be invested elsewhere
What is comparison level?
the amount of reward you believe that you deserve to get = profit
What is the comparison level for alternatives?
where we weigh up a potential increase in rewards from a potential partner, minus any costs involved in ending out current relationship
What are the four stages all relationships go through?
- Sampling = explore rewards and costs
- Bargaining = beginning of relationship - exchange rewards and costs
- Commitment = rewards and costs become more predictable
- Institutionalisation = partners settled, rewards and costs are firmly established
Evaluation of SET
+ Kurdek
asked gay, lesbian, heterosexual couples to complete questionnaire
found most committed relationships had most perceived rewards and fewest costs and viewed alternatives as unattractive
- difficult to quantify
individual differences for rewards and costs
SET is challenging to test in a valid way - assumes people are selfish and does not consider equity = not the balance of rewards and costs but partners perceptions that this is fair
- assumes all romantic relationships are economic in nature = partners don’t keep score of otherwise it would destroy the trust that underlies a close emotional relationship - not applicable
What is Equity theory?
Walster
economic theory
both partners value their levels of profit equally
when a partner is over or under benefiting the satisfaction of the relationship may decrease
not the size or amount of rewards or costs but the ratio of the two to each other
greater the perceived inequality the greater the dissatisfaction = strong correlation between the two
What are changes in perceived equity?
Equity changes as time goes on = less satisfaction than at the beginning of relationship
