what is sexual selection
explains the evolution of characteristics which enable reproductive success ( characteristics which are attractive to the opposite sex and enable us to successfully reproduce )
what is anisogamy
-the differences between male and female sex cells ( gametes )
-key factor that determines human reproductive behaviour
- there is never a shortage of fertile males, but fertile females are seen as a resource
what are the differences between male and female sex cells
- sperm = small, produced in vast quantities over a males life, do not require much energy to produce
- egg = large, produced at intervals in a females life, require a great deal of energy
what is inter sexual selection
there will be a difference in the preference of one sex for the opposite sex.
what are male mate preference strategies
- compete with other males in order to mate with as many fertile female as possible
- more attracted to younger females as they are more likely to be fertile as well as women with an hourglass figure as this is a sign of fertility.
what is intra sexual selection
members of one sex, usually male, compete with each other for access to members of the other sex. The dominant male is able to mate and will pass on their successful characteristics ( e.g. being taller and stronger )
what are female mate preferences
- have to invest more into their offspring before, during and after birth, than males so are more choosy when selecting the right male
- strength = able to protect them and their offspring
- wealth = provide food and shelter
what is the sexy son hypothesis
a female mates with a male who has a desirable characteristic and this sexy trait is inherited by her son. This increases the liklihood that successive generations of females will mate with her offspring
positive evaluation of evolutionary explanations for partners
+ Intrasexual comp in males. When men and women were asked how often their closest friends bragged about how much money they had or displayed their expensive possessions, in trying to attract a partner in the past 3 months, men were significantly more likely to have behaved this way than women. Men compete with each other for female attention.
+ intersexual selection. Male and female psych students approached other students and asked, “ would you sleep with me tonight ?”. Not a single female agreed but 75% of males said yes. Males have evolved a different dating stradegy to women.
+ consistent across cultures. 10,000 pple from 37 diff countries. Men consistently showed more preference for younger and physically attractive female partners and women consistently preferred men who were more financially stable. Universal.
negative evaluation of evolutionary explanations for partners
- presumes heterosexuality and that all relationships are sexual. Oversimplified and does not explain all types of relationships such as long distance, or couples who choose not to have children. Assumes all relationships are motivated with the desire to reproduce. Puts doubt over theory.
- ignore rapidly changing social norms. Women do not need men to provide for them as they have a greater role in the work-place and in western countries, they have greater financial security. Male preferences may not be resource orientated. Limited.
what are the 3 factors affecting attraction
1) self disclosure
2) attractiveness including matching hypothesis
3) filter theory
what is self disclosure
revealing of personal info about oneself to another.
helps develop closer more intimate relationship.
only works if it is reciprocal as it is rewarding as it signals their liking of you and their desire to be more intimate
evaluation of self disclosure
+ self disclosure linked to higher levels of intimacy in long term married couples. Less intimate couples found to self disclose less often.
+ 57% of gay men and women said that open and honest self disclosure was the main way they maintained and deepened committed relationships. Helps form relationships. Can be used to strengthen relationships by limiting small talk and encouraging self disclosure.
what is physical attractiveness
important cue for women fertility.
face symmetry - greater symmetry = greater attractiveness as it may be a signal of genetic fitness
neotenous face ( baby face ) as it triggers protective and caring instinct.
what is the matching hypothesis
people look for romantic partners who are of similar attractiveness to themselves. Involves people assessing their own attractiveness and focusing their attention on people they think are of the same level .
This is because there is less chance of being rejected and the person will feel more secure in the relationship as there is less fears that their partner might be tempted by someone else.
evaluation of physical attractiveness
+ matching hypothesis. Students assigned “ ideal “ partner for upcoming dance, this was actually random. Students expressed a greater liking to their partner when they were similar levels of attractiveness, compared to those of dissimilar attractiveness.
+ ppts shown photos of genuine couples and non genuine couple to assess levels of attractiveness. Genuine couples were more likely to be judged as having similar levels of attractiveness.
what is the filter theory
narrows down range of available romantic partners
1st filter = social demography
2cnd filter = similarity in attitudes
3rd filter = complementarity.
what is the 1st filter in the filter theory - social demography
likelihood of meeting in the first place
- those who live near us
- work with us
- socialise with us
- similar age
- geographical location
- social class
- religion
such pple will appear more attractive as their similarity will make communication easier. Anyone too different is discounted.
what is the 2cnd filter in the filter theory - similarity in attitudes
the need for new romantic partners to agree over basic values and beliefs as this makes communication easier, enabling the relationship to progress.
partners with different values are unsuitable and are filtered out.
what is the third filter theory - complementarity
how well two people fit together as a couple and meet each others needs.
two people complement each other when they have traits the other is lacking.
the need to be caring and the need to be cared for.
opposites attract.
positive evaluation of filter theory
+ 50% of citizens in Ohio were married to pple who lived initially within walking distance of their house. supports social demographic filter.
+ studying couples dating in college. couples dating less than 18 months reported that a similarity of attitudes was the most important factor in how close they felt. Those together longer than 18 months said complementarity is more important. Supports filter theory and changing importance of filters as relationships become deeper.
- however, 18 month cut off point does not represent long term relationships so can be problematic as you cant assume people who have been together longer have a deeper relationship.
additional evaluation for factors affecting attraction
- research based on correlational data. Establishes a link but cant say that one co variable causes the change in the other. may be misleading
- lacks temporal validity. Rise of online dating has changed the process of beginning a romantic relationship. Issues of social demography, self disclosure and physical attractiveness has changed as people can present themselves differently online. less likely to be limited.
- cultural bias. most theories proposed by western researchers who live in individualist cultures like the US rather than collectivist cultures like India or china. These theories may only explain romantic relationships in this type of culture. self disclosure etc may be less important in other cultures. Explanation is limited.
what are the three theories of romantic relationships
1) social exchange theory
2) equity theory
3) rusbults investment model of commitment
what is social exchange theory
- all social behaviour is a series of exchange where individuals try to maximise thier rewards and minimise thier costs.
- rewards include being cared for, companionship and sex
- costs include effort, financial costs, and time wasted
- rewards minus the costs indicate the outcome and this will either be profit ot less
- the chances of a relationship being maintained depends on the profilibility of this outcome
