Relationships Flashcards
Definition of Human Reproductive Behaviour
Behaviours related to the opportunity to reproduce and increase survival chances of our genes
2 Behaviours Included in Human Reproductive Behaviour
- Mate choice
- Mate competition
Definition of Natural Selection
Biological selection of characteristics that increase an organism’s chance of survival
Definition of Sexual Selection
Biological selection of characteristics that increase an organism’s chance of reproductive success
What is Natural Selection the Survival of?
The fittest
What is Sexual Selection the Survival of?
The sexiest
Definition of Anisogamy
The differences between make and female gametes
Sperm Cells and Biological Males - 5 Points
- About 110 million sperm per ejaculation
- Fertile for a long period of life
- Can fertilise many people with little cost to reproductive potential
- Look for signs of fertility to enhance reproductive success - health, youth, childbearing hips
- Cannot be certain of paternity so makes sense to engage in polygamy
Egg Cells and Biological Females - 6 Points
- Ovulate once a month
- Fertile for about 25 years of life
- Produce few eggs, which are a large reproductive investment
- Look for signs of genetic fitness - strength, status, resources
- Can always be certain of maternity so makes sense to engage in monogamy
- Makes sense to be selective when choosing mate as mating involves a large reproductive cost
2 Mating Strategies
- Inter-sexual selection
- Intra-sexual selection
Definition of Inter-Sexual Selection
Strategies for selection between the sexes
Definition of Intra-Sexual Selection
Strategies used between members of the same sex to be selected
Inter-Sexual Selection - 8 Points
- Preferred strategy of the female - quality over quantity
- Trivers - females invest more time, commitment and resources before, during, and after the birth of their offspring
- More important for females to be picky as they lose more than males by investing in a sub-standard partner
- Female preference for genetically fit males determines features which get passed on
- Runaway process example - if height is attractive, females will mate with tall males and produce taller sons and daughters with a preference for tall males
- Runaway process is apart of Fisher’s ‘Sexy Sons Hypothesis’
- Female mates with a male with a desirable characteristic that gets inherited by her son, which makes it more likely that future generations will mate with her offspring
- Some inter-sexual selection for males as they must choose females with indicators of fertility - young, childbearing hips
Intra-Sexual Selection - 7 Points
- Preferred strategy of the male - quantity over quality
- Involves competition between males to be the one that gets to mate with the female
- Led to dimorphism
- Example - for competing males, height matters so larger males are selected, but there is no evolutionary drive favouring larger females
- Has behavioural and psychological consequences
- Example - to acquire and protect fertile females from competition, males may behave aggressively or even benefit from thinking in certain ways
- Anisogamy suggests the optimum mating strategy for males is therefore to mate with as many fertile females as possible
Definition of Dimorphism
Obvious differences between males and female
Research into Sexual Selection and Human Reproductive Behaviour A03 - Research Support for Preferences Linked to Anisogamy - 4 Points
- Buss - survey of > 1,000 adults in 33 counties, asking questions about age and characteristics that evolutionary theory predicts to be important for partner preference
- Females found to place more emphasis on resource-related characteristics, such as good financial prospects and ambition
- Males found to place more emphasis on reproductive capacity, such as good looks, chastity, and preferred younger mates than females
- Gives credibility to the idea that sex cell differences will affect the mate selection process
Research into Sexual Selection and Human Reproductive Behaviour A03 - Research Support for Inter-Sexual Selection - 6 Points
- Clark and Hatfield - male and female students approached by a confederate that said they find them attractive and asked whether they would go to bed with them that night
- 100% of females said no and 75% of men said yes immediately
- Suggests female choosiness in heterosexual relationships is a reality
- Increases credibility of idea that females will be selective over mates as reproduction for them is a large investment, whilst males will not be selective as they benefit from polygamy to pass on genes
- However, when looking for a long-term partner, sexual strategies for males and females become much more similar, with both being choosy and looking for loyalty
- Too simplistic to suggest one strategy is adaptive for all males and the other adaptive for all females
Research into Sexual Selection and Human Reproductive Behaviour A03 - Ignores Social and Cultural Influences - 5 Points
- Social norms around sexual behaviour have changed rapidly in recent history, much faster than evolutionary timescales suggest such as the availability of contraception, meaning sex can be for pleasure
- The theory doesn’t account for homosexual relationships and those who do not want children
- Women’s position in society also means they no longer financially depend on men
- Bereczeki et al - says this changes female partner preferences to no longer be so resource-oriented
- Limited explanation as it does not account for wider social and cultural context
Research into Sexual Selection and Human Reproductive Behaviour A03 - Research Support for Men Choosing Indicators of Fertility in Women - 5 Points
- Singh - found men have a universal preference for low waist to hip ratios, with the ideal measurements standing at 36” - 24” - 36”
- This is an indicator of health and fertility as the waist to hip ratio becomes lowest during the fertile phase (ovulation) of the menstrual cycle
- A woman who is pregnant with another man’s child cannot maintain a low waist to hip ratio
- This can also explain the intra-sexual selection strategies of females who wear corsets, or crop tops, to accentuate their low waist to hip ratio
- Gives credibility to the idea that men select fertile mates to increase chances of reproductive success
Research into Sexual Selection and Human Reproductive Behaviour A03 - Research to Support The Idea That Men and Women Will ‘Offer’ Characteristics Linked to Sexual Preferences in the Opposite Sex - 4 Points
- Waynforth and Dunbar - studied ‘Lonely Hearts’ ads, which gave men and women the opportunity to describe what they wanted from a potential partner and catalogue what they had to offer them
- Women tended to offer characteristics related to physical attractiveness and indicators of youth , such as ‘sexy’ and ‘curvy’
- Men tended to offer their resources, such as ‘successful’, ‘mature’, ‘ambitious’, whilst seeking youth and physical attractiveness
- Gives credibility to ideas stemming from anisogamy that women will seek resources due to reproduction being a large investment, whilst men will seek signs of fertility to impregnate as many women as possible
Definition of Self-Disclosure
The gradual process of sharing personal information and revealing the inner self to someone
Social Penetration Theory - 4 Points
- Altman and Taylor - proposed SPT, which discuss how relationships develop, with self-disclosure being a big part of this
- Involves reciprocal exchange of information - when one reveals information they display trust, and for this to go further, the other must also disclose personal information
- With more disclosure, partners ‘penetrate’ more into one another’s lives and understand each other
- SPT includes 2 elements to self-disclosure, breadth and depth, which is illustrate with the onion analogy
Onion Analogy of SPT - 4 Points
- At the beginning of a relationship, we disclose lots of broad information, but it is low risk and and lacks depth - these are things we would share with most people
- In the early stages, we must be careful of sharing too much information, as revealing too much can threaten a relationship before it starts
- As relationships develop, self-disclosure increases in depth (removing the layers of the onion) and the breadth of acceptable topics to be discussed increases
- Eventually we reveal high-risk and intimate information (at the core of the onion), such as painful memories, strong beliefs and secrets
Definition of Depenetration
The process of a dissatisfied partner disclosing less as they disengage from a relationship
The Importance of Self-Disclosure - 3 Points
- Reis and Shaver - say that for a relationship to develop, there needs to be breadth and depth of disclosure, but also reciprocal disclosure
- Reciprocal disclosure involves one partner disclosing something about their true self and their partner responding in a rewarding way, with understanding, empathy and their own thoughts and feelings
- In a successful romantic relationship, there will be a balance of self-disclosure between partners, which increases intimacy
6 Benefits of Self-Disclosure
- Have more control of situation
- Identity management - creating the desired impression
- Potential for reciprocity
- Enhance or maintain relationship
- Catharsis - getting it off our chest
- Clarification and talking things out
6 Risks of Self-Disclosure
- Potential loss of influence or power
- Potential of being rejected
- Potential of creating a negative impression of the self
- Revealing the wrong thing that could decrease relationship satisfaction
- Embarrassment
- Upsetting someone
Self-Disclosure as a Factor Affecting Attraction A03 - Research Support - 6 Points
- Sprecher and Hendrick - Strong correlation between several measures of satisfaction and self-disclosure, from both the self and their partner, for heterosexual couples
- Sprecher et al - relationships were closer and more satisfying when disclosure is reciprocal
- Gives credibility to the idea that closer and more satisfying relationships will be marked by self-disclosure
- However, research in this area is only correlational, so a cause and effect relationship cannot be established
- Self disclosure may not cause satisfaction, satisfaction may cause self-disclosure
- Or, self-disclosure and satisfaction may both be independent, and there could be a third factor that cause both and makes them appear linked
Self-Disclosure as a Factor Affecting Attraction A03 - More Research Support - 5 Points
- Laurence et al - participants wrote daily diary entries, and found self-disclosure and the perception of self-disclosure in a partner was linked with higher levels of intimacy in long-term married couples
- Reverse also true - there was less self-disclosure for less intimate couples
- Gives credibility to the idea that closer, more satisfying relationships will be marked by self-disclosure
- However, the diary entries could be affected by biases, such as social desirability bias
- The studies would lack internal validity, so SPT may not be credible
Self-Disclosure as a Factor Affecting Attraction A03 - Cultural Differences in the Effects of Self-Disclosure - 3 Points
- Breadth and depth of self-disclosure may not lead to more satisfying relationships in all cultures and type of disclosure could be very important
- Tang et al - men and women in the USA make significantly more sexual self-disclosures than men and women in China, where there was no significant difference in satisfaction levels
- Theory that self-disclosures cause satisfaction may be cultural bound to Western countries or specific to certain types of disclosure
Definition of Sexual Self-Disclosure
Disclosures about feelings towards specific sexual practices
Self-Disclosure as a Factor Affecting Attraction A03 - There are Conflicting Explanations About the Role of Self-Disclosure in Relationship Breakdown - 4 Points
- SPT suggests intimacy increases as disclosures get broader and deeper
- It also suggests that relationship breakdown leads to depenetration
- Other theories suggest relationship breakdown involves signeted disclosure - negotiation and discussion involving deep and intimate disclosures to try and save a relationship
- The role of self-disclosure in relationship breakdown is inconsistent across theories, which reduces the reliability of social penetrate theory
Self-Disclosure as a Factor Affecting Attraction A03 - Real Life Applications - 3
- Romantic partners can learn to use self-disclosure deliberately and skilfully to increase intimacy, which is especially helpful to relationships built on small talk
- Hass and Stratford - 57% of gay men and women said deep and honest disclosure was the main way they maintained and deepened their relationship
- Research into self-disclosure has practical value, and can be used to enhance people’s real life relationships
Definition of Physical Attractiveness
Specifically relates to how appealing we find a person’s face, which is generally agreed upon within and between cultures
Definition of Neotenous Faces
‘Baby-face’ features, such as big eyes, delicate chin, and small nose
Definition of The Halo Effect
The tendency to believe everything about someone is positive because they have one positive characteristic, and they attribute that positivity to other unrelated characteristics
Definition of Physical Attractiveness Stereotype (PAS)
When we think everything about someone is positive because they are physically attractive
3 Factors Affecting Attraction
- Self-disclosure
- Physical attractiveness
- Filter theory
Evolutionary Theory Behind Physical Attractiveness - 3 Points
- Shackleford and Larsen - symmetrical faces are rated as more attractive as they are an honest signal of genetic fitness
- Neotenous features could trigger a protective/caring instinct which is valuable for females wanting to reproduce
- McNulty et al - physical attraction is not only important for attraction and relationship formation, but continues to be an important feature of relationships several years after marriage
The Halo Effect - 3 Points
- The Physical Attractiveness Stereotype can be summed up with the phrase ‘what is beautiful is good’
- Dion et al - found physically attractive people were consistently rated as kind, strong, sociable and successful compared to unattractive people
- We believe attractive people have these positive qualities, which makes them even more attractive, so we behave positively towards them - a self fulfilling prophecy
The Matching Hypothesis - 7 Points
- Despite finding physical attractiveness desirable and agreeing on what is physically attractive, we cannot all form relationships with the most attractive people
- Walster et al - proposed the matching hypothesis, which says we choose a romantic partner with a similar attractiveness level to us
- This relies on us making a realistic judgement of our own ‘value’ to a potential partner
- The same can be said for our personality and intelligence
- Romantic partner choice is a compromise, as we desire the most physically attractive partner, but balance this against the risk of rejection from someone ‘out of our league’
- We start at the ‘top of our league’ and then work our way down if rejected
- For example, if we’re a ‘6’, we might go for a ‘7’, but not a ‘9’ - if a ‘7’ rejects us, we might settle for another ‘6’
Definition of the Matching Hypothesis
Our own attractiveness has a role in our choice of romantic partner
Physical Attractiveness as a Factor Affecting Attraction A03 - Research Support for the Halo Effect - 5 Points
- Palmer and Peterson - physically attractive people rates as more politically knowledgable and competent than unattractive people
- Even true when they knew these people had no particular expertise
- Implications for political process/democracy if politicians are seen as suitable due to appearance
- Increases credibility of the idea that we perceive people as positive due to good looks
- Supports the importance of physical attractiveness in formation of romantic relationships
Physical Attractiveness as a Factor Affecting Attraction A03 - Failure To Support The Matching Hypothesis - 7 Points
- Walster at al - conducted ‘the computer dance’ study, were male and female participants were invited to a dance, and rated by observers at the start and completed questionnaires about themselves
- Told questionnaire data would decide a partner for them, but actually random
- Findings were inconsistent with the matching hypothesis, as the most liked partners were ones that were physically attractive, rather than ones who ‘matched’ one another
- Taylor et al - studied activity logs of online dating sites, measuring date choices rather than preferences
- Daters sought meetings with partners more physically attractive than them, rather than someone who was ‘in their league’
- Fails to support central prediction that we account for our own attractiveness when selecting a partner
- May still suggest physical attractiveness is an important factor affecting attraction, but not in the way predicted by the matching hypothesis
Physical Attractiveness as a Factor Affecting Attraction A03 - Research Support for The Matching Hypothesis - 7 Points
- Walster et al’s original study failed, but attractiveness measurements were unreliable, as raters only had a few seconds to judge participants’ attractiveness
- Bersched et al - replicate the study but allowed participants to select their partner from a range of people varying in attractiveness levels
- Tended to select those who roughly matched them
- Feingold - meta-analysis of 17 studies, which showed a significant correlation in rating of attractiveness between romantic partners
- Strong methodology as studies looked at actual partners rather than dating choices
- Gives credibility to the idea that we account for own attractiveness when selection a partner
- Supports importance of physical attractiveness in formation of romantic relationships
Physical Attractiveness as a Factor Affecting Attraction A03 - Individual Differences in the Importance of Physical Attractiveness - 4 Points
- Touhey - males and females asked how much they would like an individual based on a photo and some biological information
- Also completed a MACHO scale, which measures sexist attitudes and behaviours
- Those who scored highest on MACHO scale were more influenced by physical attractiveness when judging likeability, than those with low scores
- The importance of physical attractiveness can be moderated by other factors and may not be a universally important factor affecting attraction
Physical Attractiveness as a Factor Affecting Attraction A03 - Ideas About Physical Attractiveness Are Consistent Across Cultures - 6 Points
- Cunningham et al - females with large eyes, prominent cheekbones, small nose, and high eyebrows were rated attractive by White, Hispanic, and Asian males
- Suggests there are consistent ideas on what is physically attractive
- Wheeler and Kim - Korean and American students judged attractive people as more trustworthy, concerned for others, mature, and friendly
- Physical Attractiveness Stereotype is strong in both collectivist and individualist cultures
- Fixed ideas of physical attractiveness are consistent with evolutionary theory, such as facial symmetry as an ‘honest signal’ of genetic fitness
- Physical attractiveness as a factor affecting attraction appears to be universally important
Definition of Filter Theory
Explanation of relationship formation stating a series of factors progressively limit the range of available romantic partners to a smaller pool of possibilities
Filter Theory - 5 Points
- Kerchoff and Davis - compared attitudes/personalities of student couples in relationship shorter than 18 months and couples in relationships longer than 18 months
- Devised filter theory from this to explain how romantic relationships form
- Says we have a field of availables (everyone we could realistically form a relationship with), but they’re not all desirable to us
- Field of availables is narrowed down trough 3 levels of a filter to a field of desirables
- Each level of filter has differing levels of important at each stage of a relationship
3 Levels of Filter Theory
- Social demography
- Similarity of attitudes
- Complementarity
First Level of Filter Theory - Social Demography - 9 Points
- Social demographic factors affect the chances of potential partners meeting one another in the first place
- Examples include geographical location, proximity, social class, level of education, ethnic group and religion
- We are much more likely to meet people physically close to use who share demographic characteristics with us
- Most meaningful/memorable interactions happen with people nearby
- Proximity allows for accessibility, and doesn’t require much effort to people who live in the same area, go to the same school/university etc
- Wide range of potential partners, but realistic field is much narrower as our choices are constrained by social circumstances
- Anyone too different will be discounted as a potential partner
- Outcome of this is homogamy, where we are more likely to form a relationship with someone who is culturally/socially similar to us, and tend to find these shared similarities attractive
- Important at the beginning of a relationship
Second Level of Filter Theory - Similarity of Attitudes - 4 Points
- Partners often share important beliefs/values
- Similarity of attitudes is important for relationship formation, but only for couples who’d been together less than 18 months
- In early stages, partners need to agree over basic values to encourage communication and self-disclosure
- Bryne - the ‘law of attraction, where similarities causes attraction
Third Level of Filter Theory - Complementarity - 4 Points
- Involves romantic partners meeting one another’s needs and balancing each other out
- Two partners complement one another when they have traits the other lacks
- Kerchoff and Davis - found complementarity was important for long term couples in the later stages of the relationship
- Important because it appears as though a couple form a whole, which adds depth to the relationship
