What do evolutionary psychology believe about our partner preferences?
Evolutionary psychology says that we choose our partners based on psychological processes that come from out evolution
Our preferences are evolved adaptations
Outline the evolutionary explanation for partner preferences.
(6 or 8 marks)
- preferences are evolved adaptations
- we choose attractive traits because they are reliable indicators of reproductive ability
- process of sexual selection
- difference between inter-sexual and intra-sexual selection
- conflict between sexual and natural selection
- males and females have different strategies based on their evolution and anisogomy
- anisogomy
- female strategies
- male strategies
- gender differences in jealousy - sexual and emotional
- Buss, Singh, Clarke & Hatfield
Evaluate the evolutionary explanation for partner choice.
(10 marks)
supported by Buss (1989)
- more similarities between genders than differences
- both genders agreed that other factors (intelligence) are most important
- greater difference between cultures than between genders
- suggests other factors at play
supported by Singh (1993)
- unrepresentative sample
Does not look at other factors such as social factors
- enviornment/culture may have more influence than evolution, though evolution still plays a part
- e.g. countries where women do not have as many opportunities to provide for themselves as men do affects their partner preferences
What is meant by the term ‘anisogamy’?
Anisogamy refers to the difference between male and female gametes that means that men and women use different strategies when choosing their partners male and female gametes are different male female
What is intersexual selection?
Inter-sexual Selection (AO1)
Females lose more resources than men if they choose a sub-standard partner, so are pickier about who they select. They are more likely to pick a partner who is genetically fit and willing to offer the maximum resources to raise their offspring (a man who will remain by her side as the child grows to protect them both and potentially provide more children).
If they have made a good choice, then their offspring will inherit the positive features of their father and are therefore also more likely to be chosen by women or men in the next generation.
What is intra-sexual selection?
Intra-sexual Selection (AO1)
Whilst females prefer quality over quantity, anisogamy suggests that men’s best evolutionary strategy is to have as many partners as possible.
To succeed, men must compete with other males to present themselves as the most attractive mate, encouraging features such as muscles which indicate to the opposite sex an ability to protect both them and their offspring.
How do conflicts arise between natural selection and sexual selection?
A trait that makes an individual more attractive makes them less likely to survive
e. g. male peacocks and brightly coloured feathers - attractive but more noticeable to predators
e. g. masculine facial features from high levels of testosterone - attractive but makes immune system less responsive
Zahavi 1975
argued that unhelpful characteristic/threaten survival/hanicaps actually indicate survival strength
surviving dispite a handicap indicates superior genes
called this the handicap hypothesis
explains why some women are attracted to men who display reckless behaviour and take drugs
Give examples of attractive physical features.
These features are used as reliable indicators of reproductive ability
- WHR
- facial symmetry
- body symmetry
Give examples of attractive non-physical features.
intelligence personality attitudes beliefs
How do attractive features evolve?
Attractive features evolve through sexual selection
Those with features that increase their reproductive ability:
- ability to attract a mate (i.e. being physically attractive)
- ability to mate (i.e fertility)
- ability to give birth to healthy offspring who are also reproductively fit
are more likely to pass on their genes to future generations.
These features are reproductively advanatageous, so they become more prevalent in the population.
Discuss how sexual selection is related to human reproductive behaviour. (16 marks)
How does the Halo Effect work?
A person is judged to have attractive personal qualities such as being kind, trustworthy, sociable, interesting and more fun based on their physical attractiveness alone
Which research gives evidence of the halo effect at work?
Gunnell & Ceci (2010) People who are less physically attractive are 22% more likely to be convicted in court than people more physically attractive and that they are also likely to get sentences that are on average 22 months longer This suggests that physical attractiveness has a big impact on how we perceive others and that we deem physically attractive people to be more trustworthy than less physically attractive people.
What does the study by Gunnell & Ceci (2010) suggest?
It suggests that physical attractiveness has a big impact on how we perceive others and that we deem more physically attractive people to be more trustworthy than less physically attractive people
What is the Matching Hypothesis by Walster et al. (1966)?
The Matching Hypothesis suggests that people seek, are attracted to and want to start relationships with others who have the same level of physical attraction as themselves Individuals assess/evaluate their own levels of attraction first suggested to occur at a young age when we realise that not everyone can form relationships with the most attractive people identify people with the same/similar level of attractiveness as themselves because they are most attainable if we consistently choose people who are more attractive than us this would be evolutionarily foolish
The original theory of The Matching Hypothesis by Walster et al. (1966)
The original theory was that people desired partners as socially desirable as themselves and it later started to look at physical attractiveness
