Relationships Flashcards
How do evolutionary psychologists believe that people choose partners
The psychological processes that people use for partner choice come from evolution
These processes came about because when humans lived as hunter-gatherers, having certain characteristics made people well adapted to the environment.
This means that attractive traits indicate that a partner is suitable for passing on our genes
What is natural selection
Natural selection is the gradual process by which nature selects the forms most fit to survive and reproduce in a given environment
The individuals with characteristics that are most suited to the environment are more likely to survive and reproduce
The genes that allowed the individuals to be successful are passed onto the offspring in the next generation
We have evolved adaptive behaviours that ensure our survival
What is sexual selection
Sexual selection is the selection of characteristics that increase mating success
It seems that some individual possess characteristics which do not immediately appear to be beneficial to their survival
Sexual selection argues that if a characteristic increases the chances of reproduction then the characteristic will be adaptive because the animal will have more offspring
How did Singh investigate the importance of waist to hip ratio in male preference
Got male ppts aged 18-22 to rank drawings of female figures with a WHR of 0.7 to 1.0 (i.e. waist size 70% to 100% of hip size) in terms of attractiveness and ability to have children.
The drawings with a waist to hip ratio 0.7 were rated the most attractive and the most able to have children.
How may Waist to Hip Ratio indicate aspects that are attractive in females
Singh argued that low WHR is a reliable indicator of health and ability to reproduce in women.
He cited evidence that females have higher WHR before puberty and after menopause
Suggests low WHR correlates with fertility and that high WHR in women has been shown to correlate with health issues like diabetes
What does anisogamy mean and how are humans anisogamous
Means that the two sexes of animals produce gametes of two different sizes
Sperm (smaller with flagella) and egg (larger and spherical) in humans
What usually occurs in terms of sexual selection in anisogamous species
In anisogamous species, the female invests more energy in reproduction than the male
So it leads to two different types of sexual selection
What are the two types of sexual selection in anisogamous species
Intra-sexual selection
Inter-sexual selection
What is Inter-sexual selection
(preferred choice of females)
This is where one sex chooses traits they desire in the other sex
e.g. birds of paradise best dance gets to mate
This selection is between the sexes - quality strategy (selective)
The preference of one sex, therefore, determines the areas in which the other sex must compete
Peacocks - plumage
Humans - economic resources, genetic fitness
What are the reasons behind the traits that Inter-sexual selection looks for
These indicators reveal traits that could be passed on to offspring (I.e. selection for ‘good genes’)
As well as information about chances of the mate being able to give protection and support to offspring (I.e. selection for good parents)
Human beings are perceptually ‘pre-programmed’ to attend to displays of these important indicators
This increases their willingness to mate with the individual who possesses them
What are female strategies with regards to inter-sexual selection
Fisher’s sexy sons hypothesis
A woman chooses a man because he has a characteristic she wants (e.g. tall male)
Any male children she has will inherit this characteristic and will be more desirable to women
Over generations the characteristic becomes more pronounced - this is known as the runaway process
This only stops when the trait becomes too costly or female preference changes
Girls that are born with tall fathers have a desire for tall men
What is Zahavi’s handicap hypothesis
A women chooses a man with a handicap because it advertises his ability to thrive despite handicaps, demonstrating superior genes
E.g. females findings males attractive who drink or take drugs in large amounts - demonstrates an ability to handle toxins, a sign of genetic fitness
How may natural selection and sexual selection have conflict
Sexual selection refers to traits that give a reproductive advantage
Natural selection also happens with traits that give a survival advantage - traits that make it more likely an individual will survive long enough to reproduce (e.g. health).
Sometimes the traits that are attractive to a mate make an individual less likely to survive, so sexual selection can conflict with natural selection more generally.
E.g. female peacocks find the long, brightly coloured tails of male peacocks attractive, but very brightly coloured tails are more noticeable to predators
What is intra-sexual selection
(usually males)
Competition and selection between members of same sex
Winners get to mate and pass on their genes so whatever traits lead to success in these same sex contests will be passed on to the next generation
quantity strategy (indiscriminate)
What is sexual dimorphism
Relates to intra-sexual selection
Result of male competition
Winners get to mate and pass on their genes so whatever traits lead to success in these same sex contests will be passed on to the next generation
Sexual dimorphism concerns the different characteristic that male and females possess
Male on average 12-15% larger than female
Also includes secondary sexual characteristics such as deeper voice, facial hair in males and breasts, hips, smoother skin in females
These features increase the chances of survival into adulthood and sexual maturity, where genes are passed to the next generation
How is sperm competition a male strategy with regards to intrasexual selection
Physically size matters for men
Behaviourally- aggression may matter
Compete by producing larger testicles, bigger ejaculations and faster-swimming sperm
How is sneak copulation a male strategy with regards to intrasexual selection
Males mate with females other than their partners if given the opportunity, as it increases their chance of reproductive success
Women gain from this by having a wider genetic diversity to their children, increasing survival chances
Women can also gain by being in a relationship with a resource-rich male, copulating with a genetically fit stud
What did Cartwright say we find attractive
Said both men and women prefer symmetrical faces
Symmetry equates with reproductive fitness
Cartwright also found that women with symmetrical breasts are more fertile
Women with symmetrical male partners have the most orgasms
Method of Buss’s study of gender differences in mate selection
Questionnaires were used to collect data from over 10 000 men and women from 37 different cultural groups.
The questionnaires covered demographic information such as age, gender and marital status.
They also asked about preferences for variables such as marriage, age differences and characteristics in a mate (e.g. intelligence, sociability and financial prospects).
Results of Buss’s study of gender differences in mate selection
Women valued variables associated with gaining resources (e.g. money, safe environment) more highly than men.
Men valued variables associated with reproductive capacity (e.g. youth) more highly than women.
Conclusions of Buss’s study of gender differences in mate selection
The factor limiting men’s reproductive success has been access to fertile women, and so they have evolved to be attracted to women with a high likelihood of reproducing
Women have had limited access to the resources needed to provide for themselves and their offspring.
So, they’ve evolved (through sexual selection) to select mates who can provide these resources.
Evaluation of Buss’s study of gender differences in mate selection
There were similar findings across a range of different cultures.
However, it wasn’t a truly representative study as it was hard to include rural and less educated populations.
Cross-cultural research is important as it suggests universality, providing strong evidence for an evolutionary explanation of gender differences in sexual selection.
Positive evaluation of sexual selection: Buss’ study
Include details from Buss’ study
Negative evaluation of sexual selection: oversimplified
The evolutionary explanation presumes heterosexuality
Assumes that all relationships are sexual
It cannot explain couple choosing not to have children, as it assumes all relationships are motivated by a desire to reproduce
How did Clark and Hatfield’s study provide support for intersexual selection and anisogamy
Attractive male and female psychology student (confederates) approached opposite sex strangers on a university campus and asked one of three questions:
Would you go out with me tonight?
Would you come over to my apartment tonight?
Would you go to bed with me tonight?
Shows women mate wisely while men mate widely
Positive evaluation of sexual selection: ovulating lap dancers
Most female mammals display oestrus to alert males to receptivity, oestrus is thought to be hidden in humans
Compared earnings of lap dancers menstruating naturally with those on the pill
During non-fertile periods, both sets of dancers earned similar tips
But when dancers not on the pill entered fertile phase, they earned significantly more tips than pill taking dancers
Positive evaluation of sexual selection: lonely hearts
Content analysis of personal ads in 4 newspapers by Waynford and Dunbar
479 male ads, 402 female ads
Males
Included indications of material wealth 1.7 times more than women
Men aged 40-49 most likely to express preference for female fecundity (ability to produce young in great numbers)
Females
Twice as likely as males to advertise their physical attractiveness (curvy, exciting)
Demanded wealth in partner 4.5 times more often than men
Mentioned ‘youth’ more
Supports anisogamy
Negative evaluation of sexual selection: Campos’ study of choosy old men
Studied personal ads
As women aged, they became less demanding Whereas men became more demanding, with age
Negative evaluation of sexual selection: Explanation ignores social and cultural influences
Partner preferences over the past century have been influenced by rapidly changing social norms of sexual behaviour
Evolutionary timescales are not as quick as cultural factors such as availability of contraception
Bereczkei - women in the workplace do not depend on men
No longer resource orientated
What is self disclosure
Self disclosure involves revealing personal information about yourself
Romantic partners reveal more about their true selves as the relationship develops
These revelations strengthen the relationship if used appropriately
What is the social penetration theory
By Altman and Taylor
Relationships are gradual process of revealing your inner self to someone
In romantic relationships it involves reciprocal exchange of information between partners
Leads to a deep understanding of each other’s lives
Two elements to this idea - breadth and depth
How does the onion model explain social penetration theory
Shows layers of information
Low risk information is revealed early on in a relationship and high risk information comes out as the relationship progresses
How may reciprocity of information deepen the relationship
Tends to be a balance of self disclosure in successful romantic relationships, as well as breadth and depth
After disclosing information, you want your partner to respond in a rewarding way, with understanding and empathy
Increases intimacy and deepens the relationship
What was discovered about partners who exchanged information about eachother
It was found that people like someone more if that someone self discloses to them
They also like someone more if they have disclosed information to that person
What factors regarding disclosure may influence the relationship
Appropriateness of the disclosure:
Sometimes disclosing personal information is inappropriate
E.g. on a first date - suggests that the individual is lacking in social skills
More attractive people will be sensitive to these norms
How can the perceived reasons for disclosure influence attraction
The reasons we believe a person is self-disclosing to us are important
Less attraction occurs if an individual is seen as the kind of person who discloses personal information to everyone
However, more attraction occur if we believe an individual sees us as someone they especially want to disclose intimate info to
Gender differences when it comes to self disclosure
Women generally are seen as better communicators of and more interested in intimate information
Therefore intimate self-disclosures by males may be seen as less appropriate than those by females
Alternatively, self-disclosure by a male may be seen as very rewarding by a female
Meanwhile, males may feel threatened by females self-disclosing intimate details to them
How can the content of the information that is disclosed affect attraction
Disclosure of highly intimate information may be seen as inappropriate and as violating social norms, especially if a relationship is in its early stages
This could decrease attraction
Attraction is strongest when self-disclosure if of moderate intimacy and weaker when too high or low
Positive evaluation for self disclosure: support from research studies
Several predictions about self-disclosure from social penetration theory are supported by research
Study of heterosexual dating couples found positive correlations between several measures of relationship satisfaction and self-disclosure (both theirs and their partners)
Positive evaluation for self disclosure: Real life applications – communication
Research into self-disclosure can help people who want to improve communication in their relationships.
Romantic partners probably use self-disclosure deliberately and skilfully from time to time to increase intimacy and strengthen the bond.
Study found that 57% of gay men and women said that open and honest self-disclosure was the main way they maintained their relationships.
This finding demonstrates the value of psychological insight
Negative evaluation for self disclosure: Cultural differences
Study reviewed research regarding sexual self-disclosure and concluded that men/women in USA disclose significantly more sexual thoughts than men/women in China (individualist Vs collectivist cultures.)
Both are linked to relationship satisfaction in those cultures
May show cultural bias.
Negative evaluation for self disclosure: Self-disclosure and satisfaction
Social Penetration Theory claims that romantic relationships become more intimate as self-disclosures deepen and broaden.
Using the onion metaphor, relationship breakdown is accompanied by the reduction in self-disclosures.
However, according to theories of relationship breakdown often recognise how couples discuss and negotiate the state of their deteriorating relationships in an attempt to save it or return it to an earlier level of satisfaction.
These discussions will frequently involve deep self-disclosures of very intimate thoughts and feelings, and yet these might not be enough to save the relationship.
In fact these might even contribute to the breakdown of the relationship
Negative evaluation for self disclosure: Individual differences
The personality of recipients may be an important factor in whether self-disclosure increases the attractiveness of potential partners.
Different individuals would have different needs for levels of intimacy in relationships and this would affect how attractive they would find intimate self-disclosures.
Negative evaluation for self disclosure: Too reductionist
It is unlikely the attractiveness of a potential partner would be reliant purely on the level/type of self-disclosure that an individual makes.
It is more likely that self-disclosure would interact with other considerations, such as level of physical attractiveness, similarity of interests/attitudes
Negative evaluation for self disclosure: Correlation vs. causation
Correlational research does not establish a cause.
Therefore, it is not a valid conclusion to draw that greater self-disclosure creates more satisfaction
There could be alternative explanations for this correlation
What are the factors affecting attraction
Self disclosure
Physical attractiveness
Filter theory
What is physical attraction
An important factor in the formation of romantic relationships
The term usually applies specifically to how appealing we find a person’s face
There is a general agreement within and across cultures about what is considered physically attractive
How have we found that physical attractiveness is important in relationships
Shackelford and Larson found people with symmetrical faces are more attractive as they have an honest signal of genetic fitness
People are also attracted to baby-face features (neotenous) - large eyes, delicate chin and a small nose as they trigger an instinct of protection and caring
Physical attractiveness continues to be an important feature of a relationship after marriage, for at least several years
What is the halo effect
Physically attractive people are rated as more kind, strong, sociable and successful compared to unattractive people
The belief that good looking people will have such characteristics makes them more attractive to us, so we behave more positively towards them - a self fulfilling prophecy
What does the matching hypothesis state
People choose romantic partners who are roughly of similar physical attractiveness to each other
To do this we have to make a realistic judgement about one’s own value to a potential partner
Positive evaluation of physical attractiveness: research support for halo effect
Study found physically attractive people were rated as more politically knowledgeable and competent than unattractive people
Persisted when people knew that the knowledgeable people had no expertise
Obvious implications for the political process
Negative evaluation of physical attractiveness: individual differences
Not all people place importance on physical attractiveness:
Study asking male and female ppts to rate how much they would like a target individual based on their photograph and some biographical information
Competed a questionnaire to measure sexist attitudes (MACHO scale)
Ppts who scored highly on the questionnaire, were more influenced by physical attractiveness, when making their judgement on likeability
Positive evaluation of physical attractiveness: Research support for the matching hypothesis
Meta analysis of 17 studies and found a significant correlation in ratings of attractiveness between romantic partners
Method of Walster’s computer dance study
A computer dance was advertised in a handbook given to new university students and tickets were sold to 376 men and 376 women.
The people selling the tickets secretly rated each student for attractiveness.
The students were not told they were participating in a study.
Instead they were told that a computer would match them with a date for the dance who shared their interests.
In fact, the ppts were paired randomly with somebody of the opposite sex, although no men were paired with taller women.
During the dance the participants filled in a questionnaire about their date.
Ppts were contacted four to six months later to find out of they’d tried to go on any further dates with their dance date.
Results of Walster’s computer dance study
Ppts paired with a similarly attractive partner were not significantly more liked by their date than those paired with a partner with a different attractive rating to them.
Ppts who were rated as more attractive were more liked by their date.
More attractive participants were also more frequently asked out on further dates than less attractive participants
Whereas there was no correlation between similarity in attractiveness in a pair and the number of times participants were asked out again
Conclusion of Walster’s computer dance study
The matching hypothesis was not supported- the results showed that people prefer attractive partners regardless of their own attractiveness
Evaluation of Walster’s computer dance study
Study was different from usual dating as the ppts did not choose one another and neither of them had to ask each other on a date.
Low ecological validity.
The way the attractiveness of the ppts was judged may mean results are not reliable
Results don’t support matching hypothesis: evidence from the study is from relationships that had already started rather than choosing to start a relationship
What are the 3 levels of the filter in filter theory
- Social demographic filter
- Similarity in attitudes filter
- Complementarity filter
What is social demographic filter
We initially form a ‘field of availables’
These are potential people to form a relationship with
Based on social and demographic factors such as age, religion, living near eachother
Outcome is homogamy - form relationships with someone who is socially or culturally similar
What is the similarity in attitudes filter
We narrow the set of available people down to a smaller ‘field of desirables’
These are people who a relationship is more likely to progress with.
This filter is based on sharing similar attitudes, values and interests
May be same ethnicity or racial group
Better to agree over basic values as it encourages greater and deeper communication and promotes self-disclosure
