Relationships Flashcards
What is meant by the evolutionary explanation?
Focuses on the adaptive nature of behaviour. Modern behaviours are believed to have evolved because they were passed on by ancestors and became more widespread in the gene pool
What is meant by sexual selection?
(Darwin) evolution is driven by competition for mates, and the development of characteristics ensure reproductive success
What is meant by reproductive success?
Contingent on attracting a mate, overcoming competitors and survival of offspring
What is meant by anisogamy?
The differences between male and female gametes
Outline intersexual selection
Members of one sex evolve preferences for desirable qualities in potential mates. Members of the opposite sex who possess these characteristics gain a mating advantage
What is the driver behind intersexual selection?
Low quality/less desirable mates who are unhealthy and unattractive are more likely to produce offspring that also possess these attributes
Which sex prefers intersexual selection?
Females
Outline intrasexual selection?
Individuals of one sex (males usually) must outcompete other members of their sex in order to gain access to the opposite sex.
What does anisogamy suggest about males?
Male’s optimum strategy is to mate with as many females as possible
What characteristics do females prefer in males?
- Able to invest resources
- Physically fit, for protection purposes
- Show promise as a good parent
What characteristics do males prefer in females?
Display good reproductive value
What is meant by the matching hypothesis?
Claims that when people look for a partner, they tend to look for someone whose social desirability approximately equals their own
How does the matching hypothesis work?
- Asses their own ‘value’
- By opting for partners of similar social desirability to themselves, they can maximise their chance of a successful outcome
- In modern society, matching has become more based on physical attractiveness alone rather than demographic qualities
Outline the procedure for Walster et al (1966) computer dance study
- University students randomly selected
- Completed a questionnaire
- Told the data would be used to match them with their ideal partner, it was done randomly
- After the dance they completed a follow up questionnaire about how it went with their set partner
Outline the findings for Walster et al (1966) computer dance study
- Did not support the matching hypothesis because results showed participants actually preferred people who were more attractive than them
- Other factors such as personality did not affect subsequent attempts to date them
What are weaknesses of the evolutionary explanation?
- Reductionist: ignoring social and cultural influences (women’s independence - less reliant on man)
- Weaknesses in research: use of undergraduate students who look for resourceful men out of similarity
- Largely based on speculations - no reliable way to check these suggestions are valid
What was the aim of Buss (1989) study of evolutionary explanations?
Buss explored anisogamy for partner preference
What was the procedure for Buss (1989) evolutionary explanation research study?
- 10,000 people from 37 different cultures
- Asked to rate 18 characteristics (physical attractiveness, financial resources) on how important they would be in choosing a mate
- A 4 point scale was used, ranging from ‘3’ (indispensable) to ‘0’ (irrelevant)
What was the findings for Buss (1989) evolutionary explanation research study?
Resources: Women desired mates who had financial resources
Physical Attractiveness: Men placed importance on physical attractiveness. Indicates fertility/reproductive value
Youth: Men universally wanted mate who were younger (also indicates fertility)
Other Important Characteristics: both sexes wanted mates who were intelligent (linked to parenting skill) and kind (interest in commitment)
What can be said about gender differences and the matching hypothesis?
Buss (1989) demonstrated that men place great importance on physical attractiveness when choosing a mate. This is because it is a cute to a woman’s health and fertility. More recent research (Eastwick, 2011), suggests that it may also be just as important to women as it is to men
How does the matching hypothesis work?
- Assess their own value
- Select candidates of their value
- By opting for partners of similar social desirability to themselves, they can maximise their chances of a successful outcome in reproduction
What features are considered attractive?
Baby face in females, heavy brown and strong jawline in males
What are some general weaknesses of the physical attractiveness/matching hypothesis?
- Individual differences; some people don’t place much importance on physical attractiveness
- Taylor et al; found that online daters met with potential partners who were actually more attractive - supporting computer dance study
What are some general strengths of the physical attractiveness/matching hypothesis?
- High population validity; Wheeler and Kim (1997) found that regard for physical attractiveness was just as high in collectivist cultures as individualist
- Feingold (1998) meta analysis found significant correlation in ratings of attractiveness between romantic partners
- Other research support (mind map)
