What is sexual selection?
How is it different to natural selection?
- Evolution driven by competition for mates development of characteristics that ensure reproductive success.
- natural selection explains characteristics that offer a survival advantage, sexual selection explains characteristics that offer a reproductive advantage.
Define intersexual selection
- Preference of one sex for member of opposite sex with certain qualities.
- Women=quality over quantity, optimum strategy to select a genetically fit partner able and willing to provide resources.
- Selection based on indicators-reveal traits we may want to pass on to offspring (good genes) as well as likelihood the mate will survive to provide for the offspring (good parents).
Define intrasexual selection
- Competition between (intra) males, to be able to mate with a female.
- Winner of the competition reproduces.
- Meaning he gets to pass on to his offspring the characteristics that contributed to his victory.
- Given rise to dimorphism in humans – the obvious differences between males and females.
Outline the short term mating strategies
- male’s optimum reproductive strategy is to mate with as many fertile females as possible-quantity over quality.
- Due to minimal energy required to produce enough sperm & relative lack of post-coital responsibility
- Buss and Schmitt= men have a marked decrease in attraction to a partner following copulation (an evolved adaptation to ensure they don’t spend to long with one person).
- Female’s optimum reproductive strategy is to select one high quality mate to ensure she does not waste reproductive energy on low quality offspring.
- Because even if a female sleeps with 20 males in a short period she would still only produce a single child.
Outline the long term mating strategies and how they are different to short term
-Being choosy is good, as the genetic quality of the mate you choose will directly influence 50% of your offspring’s genes.
Low quality, unattractive mates will produce low quality unattractive offspring – if your offspring cannot mate, then your genes will not continue on down the generations.
Outline Buss’ study into long term partner preferences
Procedure:
- Studied over 10,000 people from 37 different cultures.
- Pps asked to rate each of the 18 characteristics (attractiveness, finances etc) on how important they are in picking a mate
- Four point scale from irrelevant to indispensable was used.
Results:
Found key differences between the genders cross culturally…
-Resources: Women were more bothered about resources-wanted men with good financial prospects, and qualities like ambition and industriousness.
-Attractiveness: men placed more importance on this-provides them with information on women’s health and fertility.
-Youth – Men universally wanted mates who were younger-indicated fertility.
-Intelligence – both genders values this-indicated parenting skill.
Evaluate the evolutionary explanations for partner preferences
+Support for gender differences in short term mating= Clarke and Hatfield (1989) used attractive males and female who approached strangers on a university campus with various requests including going back to their room for sex.
No females and 75% of male agreed. This has been replicated in other studies.
-link= (males therefore have a preference for casual sex).
+Support from Lonely Hearts Research= Wayneforth and Dunbar studied lonely hearts advertisements in American newspapers.
-These were opportunities to describe the qualities you desired in a potential partner, whilst cataloguing what you had to offer.
-Found that women, more than men, tended to offer physical attractiveness and indicators of youth (flirty, sexy, curvy, exciting).
Men on the other hand, offered resources more than women did (successful, fit, mature, ambitious) and sought relative youth and physical attractiveness.
-Support from waist-hip ratio research= males will show a preference for the female body shape that signals fertility. What matters in male preference is not the female body size as such, but the ratio of waist to hip sizes.
-Singh (1993, 2002) found= must be 0.7.
Combination of wider hips and narrower waist attractive=‘honest signal’ (hard to fake) that woman is fertile but not currently pregnant.
Weakness- Is culture more important than evolution?
- Some argue women been denied economic and political power in many cultures-might account for reliance on men for resources.
- Kasser and Sharma (1999-women valued resources more in cultures where their statues and educational opportunities more limited.
Weakness= theory is outdated, ignores role of contraception= original Clarke and Hatfield study was done in 1989, it’s quite possible that nowadays women would be more likely to accept an invitation for casual sex due to the wider use of contraceptives.
It is now possible for a female to engage in casual sex without the risk of conception.
-Weakness- Methodological criticisms with Buss’ study- Low ecological validity= often focuses on preferences rather than real life choices.
Define anisogamy
-The difference in male and female sex cells
-Men have sperm cells, which are able to reproduce quickly with little energy expenditure and once they start being produced they do not usually stop until the man dies.
Female gametes (eggs or ova) are, in contrast, much less plentiful; they are released in a limited time frame (between puberty and menopause) and require much more energy to produce. This difference (anisogamy) means that men and women use different strategies when choosing their partners.
- Outline self disclosure
- Research
- When a person reveals intimate or personal information about themselves to another person
- Jourard- self disclosure=important process in developing romantic relationships-greater disclosure=greater feelings of intimacy
- Most are careful what they disclose, at least at first, most prefer those who disclose more intimate details than those who don’t.
- Collins & Miller- people reveal more to those they like, tend to like those they have revealed the information to.
Outline the key study into self-disclosure
-Spretcher et al (2013)=
Interested in whether reciprocal self-disclosure was more influential in determining attraction than one-sided self-disclosure & listening.
Procedure=
- 156 undergraduate students were paired up. (2/3 were female-female). Each ‘dyad’ (pair) was unacquainted and began a self-disclosure task over skype.
- Reciprocal condition=
- Each member of the pair took turns disclosing information and asking questions.
- Non-reciprocal condition=
- one person asked questions and the other person disclosed.
- After this, the researchers assessed liking, closeness, perceived similarity and enjoyment of the interaction.
Results:
-Reciprocal condition=
Partners reported more liking, closeness, similarity and enjoyment.
-Non-reciprocal condition
swapped roles.
-Ratings of liking, closeness, similarity and enjoyment still higher in reciprocal group, even after non-reciprocal group swapped.
-This shows that turn taking self disclosure is more effective than extended reciprocity in disclosure.
-level of self-disclosure received=better predictor of liking and loving than self-disclosure that is given.
-amount of overall disclosure was predictive of whether the couple stayed together for longer than 4 years.
Outline social penetration theory
- As each partner increasingly reveals more and more information about one another, romantic partners ‘penetrate’ more deeply into each other’s lives
- Gaining a greater understanding of each other and a deeper connection. This is a basic feature of romantic relationships.
Evaluate self disclosure
- Stength= Research support= Sprecher and Hendrick (2004) studied heterosexual dating couples
- Found strong positive correlations between several measures of relationship satisfaction and self-disclosure (giving and receiving).
- The reverse was also true – less intimate couples self-disclosed less often.
-Weakness- Self disclosure does not always lead to satisfaction= according to theories of relationship breakdown 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.
- Strength= Real life Applications= 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.
- Hass and Stafford (1998)=57% of gay men and women said that open and honest self-disclosure was the main way they maintained their relationships.
- Weakness- Cultural Differences= prediction that increasing depth and breadth of self-disclosure will lead to a more satisfying and intimate relationship is not true for all cultures.
- Wester cultures=engage in more intimate self-disclosure than non-western cultures.
- Tang et al (2013) reviewed research regarding sexual self-disclosure-concluded that men/women in USA disclose significantly more than men/women in China (collectivist Vs individualist cultures.)
- Weakness- Online relationships differ in self-disclosure= Relationships formed on internet=higher self-disclosure than face to face relationships.
- On the internet we feel more anonymous which gives us greater comfort to reveal more about ourselves.
- Cooper and Sportolari (1997) call this the ‘boom and bust’ phenomenon.
- When we reveal more online more quickly this is the ‘boom’, however because the trust is not there this is difficult to sustain, this is the ‘bust’.
-However- Knop et al challenged this- people disclose more face to face than online- eye contact and attentive silence of our partner - both of which are absent in online relationships.
Outline Altman and Taylors breadth and depth
- As both breadth and depth increases, romantic partners become more committed to one another.
- Start of a relationship= disclose a lot of ‘low risk’ information about ourselves, but what we reveal tends to be superficial, mostly ‘on the surface’ information,
- Like the outer layers of an onion.
- ‘Low risk’ information we would reveal to anyone, friends, co-worker, even acquaintances.
- The depth of disclosure is shallow because at this stage many topics are ‘off limits’ in the early stages of a relationship.
- If we reveal too much too soon, we may get the response ‘too much information’, possibly threatening the relationship before it gets going.
- as the relationship develops, self-disclosure becomes deeper, progressively removing more and more layers to reveal our true selves and encompassing a wide range of topics, especially those concerning things that matter most to us. Eventually we are prepared to reveal intimate, ‘high risk’ information e.g. painful memories and experiences.
Outline Reciprocity of Self Disclosure
Reis and Shaver (1988) make it clear that for a relationship to develop, as well as increase in breadth and depth, there needs to be a reciprocal element to disclosure.
Once you have decided to disclose something that reveals your true self, hopefully your partner will respond in a way that is rewarding to you. Eg. Understanding, empathy and also their own intimate thoughts and feelings.
The key here is that there must be a balance of self-disclosure between both partners in a successful romantic relationship, which increases feelings of intimacy and deepens the relationship.
Outline why physical attractiveness is so important
- Buss’s partner preferences research in different cultures=men place a greater importance on physical attractiveness when choosing a mate.
- Because it acts as an indicator of health and fertility.
- However more recent research suggests that physical attractiveness may be just as important to women. However it is complicated.
- Women see physical attractiveness as more important in short term relationships, but less important in long term relationships, however men still rely on physical attractiveness for both types of relationship.
Outline research into facial symmetry
- Rhodes et al (1998) suggest that facial symmetry is attractive, because it may signal mate quality.
- Tested prediction that facial symmetry is attractive by manipulating the symmetry of individual faces and observing the effect on attractiveness.
- Found that attractiveness increased when symmetry increased, and decreased when symmetry was reduced.
Outline little et al’s research into masculine and feminine features
-Examined human preferences for masculinity/femininity in different types of stimuli.
-Face and body stimuli
-Images were manipulated to be more or less masculine using computer graphic techniques.
For women-found that preferences for more masculine stimuli were greater for short-term than for long-term relationships across all stimuli types.
-Further analyses revealed consistency in preferences for masculinity across stimuli types, at least for short-term judgments, whereby women with preferences for masculinity in one domain also had preferences for masculinity in the other domains.
For men- found that preferences for more feminine stimuli were greater for short-term than for long-term judgments across face and voice stimuli, whereas the reverse was true for body stimuli.
Outline the halo effect
- Describes how one distinguishing feature (physical attractiveness, in this case) tends to have a disproportionate influence on our judgements of a person’s attributes, for example, their personality.
- Knowing someone is physically attractiveness means we may also assume/stereotype that they are good, kind, honest etc.
- We have preconceived ideas about personality traits attractive people must have-almost universally positive- Dion= physically attractive people are consistently rated as strong, sociable & successful compared to unattractive people.
- Belief that good looking people probably have these characteristics makes them even more attractive to us, so we behave positively towards them – a good example of a self-fulfilling prophecy.
Outline the matching hypothesis
-States that people choose romantic partners who have a similar level of social desirability to themselves. The matching hypothesis includes two hypothesis:
The more socially desirable a person is (physical attractiveness, social standing, intelligence) the more desirable they expect their dating partner to be.
Couples who are matched (both partners are equally desirable) are more likely to have happy, enduring relationships than those who are mismatched.
-When choosing a partner we must first identify our own level of attractiveness, our own value.
We then rate potential partners for attractiveness (work out what we desire)
We compare this with their own level of attractiveness (our own value)
And consider the likelihood of being rejected
And the possible alternatives for both parties
-This comparison determines whether they will pursue the person as a potential mate. Walster et al refer to this notion as realistic choices as each individual is influenced by the chance of having their affection reciprocated.
Outline Walster et al research into the matching hypothesis
Procedure=
-347 Undergraduates from University of Minnesota attended a ‘get acquainted’ dance
-Randomly selected to take part.
When they came to pick up their ticket they were covertly rated on attractiveness.
-Asked to complete a lengthy questionnaire on personality, intelligence etc and told this data would be used to allocate them an ‘ideal partner’ for the date.
-Randomly matched with a date.
-During the intermission of the dance asked to complete a questionnaire about their date-also completed a questionnaire 6 months later.
Results=
-Findings did not support the matching hypothesis. Once paired, regardless of their own attractiveness they responded more positively to physically attractive dates and were more likely to try to arrange follow up dates with them. Other factors like personality and intelligence did not affect their liking of the dates.
Even when researchers manipulated the physical attractiveness of the date and presented false information about how likely the date would be to enter into a relationship with the participant, the physical attractiveness effect (ie liking someone more the more attractive they are) predominated over a matching effect or any concern about rejection.
