definite sexual selection
explains how evolution is driven by competition for mates, and the development of characteristics that ensure reproductive success
define intrasexual selection
- individuals must outcompete other members of their own sex to gain access to members of the other sex
- successful individuals are able to pass on their genes
define intersexual selection
- individuals evolve preferences for desirable qualities in potential mates
- members of the opposite sex who have these characteristics will then gain a mating advantage over those who don’t
- the preferences of one sex determines the area in which the other sex must compete
what is the rationale behind sexual selection
- good to be picky as the genetic quality of mate will determine half of the genetic qualify of an offspring
- low quality mates = more likely to produce unattractive offspring so pair up with attractive mate and those genes will be passed on
sexual selection means that females are attracted to what sort of mates?
- resourceful
- can physically protect them and child
- show promise of being a good parent
- compatible
however, mates are more attracted to females who show fertility
outline producers and findings of Buss’s study ( evolutionary explanations for partner preferences )
- 10,000 people from 37 cultures
- participants asking to rate characteristics on how important they would be in choosing a mate
- four point scale used from 3 (indispensable) to 0 (irrelevant)
- women more than makes desired mates with good financial prospects
- men placed more importance of physical attractiveness and universally wanted mates who were younger them themselves -increased fertility
- both sexes wanted mates who were intelligent and kind
the evolutionary perspective argues what…
that the preferences,behaviours and relationships of men and women today have their origins in the evolutionary past
natural and sexual selection may explain the differences in what
- what men and women find attractive
- the qualities they seek in partners
- differences in human reproductive behaviours
explain Cunninghams investigation on what males find attractive in females
- investigated what types of female faces are found attractive by males
- systematically varied the size of the female facial features. Used same female face picture but altered features on computer. This acted as a control variable
- found that men were most attracted to features associated with young children - large eyes, small nose etc
- some features associated with maturity such as prominent cheekbones were also found attractive
what did Singh found out about body shape
-men ranked women with a small waist to his ration of around 0.7 (waist 70% size of the hips) as the most attractive and healthy
what did Waynforth find out about what females find attractive in males
- masculine facial features including a square jaw, rigged eyebrows, thin lips were preferred by women, especially those seeking a short term partner
- the ideal waist to hip ratio in makes was around 0.85. Wide shoulders down to narrowing hips
what is found attractive to both females and males ?
- symmetrical faces (Bruce and Young)
- Pawlowski asked a sample of 218 males and females to rank attractiveness of 7 pictures of men and women which were altered in leg length. In both sexes 5% longer than average legs were seen as the most attractive
explain what Buss found in his cross cultural study in partner preferences
- men valued physical attractiveness more than women
- men valued women who were younger than themselves
- women valued financial capacity and qualities that are associated with this (ambition)
what study confirmed Buss’s on partner preferences ?
- Dunbar and Waynforth
- study used 900 personal adverts from North American newspaper
- however, only within one culture so not representative of the whole population
explain Clark and Hatfield’s study on differences in reproductive behaviours
- male and female students approached total strangers of the opposite sex on campus and made a suggestion of sex
- the three requests were: to go out with them that night, to go back to their house with them or to have sex with them
- 50% of men and women agreed to go out with them that night
- none of the women agreed to have sex with a stranger
- 75% of men agreed to have sex
explain the research to support the claim that men tend to seek and desire a greater number of sexual partners than women
- Buss and Schmitt asked how many sexual partners people would want over the next two years, the next decade and during their lifetime.
- men would like 8 partners over the next two years compared to women’s 1 partner
- over a lifetime, 18 for men and 4-5 for women
explain Buss’s study in differences in sexual jealousy
- asked male and female students to imagine their partner either having sex with someone else or in love with them
- they were wired up to measure stress response during this
- men become most distressed at the thought of their partner being sexually unfaithful
- women became most distressed at the idea of their partner in love with someone else
what did Ellis and Symons discover about sexual fantasies and dreams
men are more likely to have sexual dreams than women, especially those involving multiple partners
define anisogamy
the differences between male and female gametes
explain Buller’s argument that female preference for high status men may not be universal
- studies attempting to determine female mate preferences have been carried out on female undergraduate students
- problem with class and age group. Sample doesn’t represent whole population
- these women expect to achieve high educational status and so have expectations of high income levels.
problem with Buss’s study on partner preferences, counter argument and then another problem
- the results expressed preferences instead of what actually happens. This is a problem of self report
- however there is support for Buss from real life. A study of real marriages showed that from 29 cultures men do choose younger women
- consider social desirability of being asked how many partners would be desirable over different time periods. Answers may reflect the social construction of masculinity and femininity.
explain the problem with partner preferences studies that they ignore social and cultural influences
- Bernstein points out that gender differences in mate preferences may result from cultural traditions rather than evolved characteristics
- e.g. the fact that women have been denied economic and political power in many cultures might account for their tendency to rely upon security and economic resources from men
- analysis showed that women valued mates with status and money for more in cultures where women’s status and opportunity were limited
what is the research support for inter sexual selection from Clarke and Hatfield
- showed that female choosiness is a reality of heterosexual relationships
- male and female confederates approached other students on campus with the question ‘I have been noting you around campus, I find you to be very attractive. Would you go to bed with me tonight?’
- not a single female agreed to the request
- 75% of males did
what did Dion and Wheeler and Kim find out about physical attractiveness and stereotypes
- physically attractive people are consistently rated as kind, strong, sociable and successful
- this stereotype is also seen culturally. Wheeler and Kim found that Korean and American students judge physically attractive people to be more trustworthy, concerned for other people.
- the stereotype was just as strong in collectivist cultures as it is in individualist cultures
what is the matching hypothesis? Walster and Walster
- individuals do an evaluation of themselves
- they make a realistic choice on relationships
- realistic choices consider the individuals ideal and the likelihood of their acceptance
- most likely, they select the best candidates from those whose social desirability (physical attractiveness) equals their own
- by making realistic choices, individuals minimise rejection
3 pieces of research to support matching hypothesis
- Murstein asked dating couples to rate their physical attractiveness, and asked independent judges to rate them. Found that real pairs were more similar in terms of physical attractiveness than random pairs
- Silverman confirmed these findings in a field study. Noticed that the greater the degree of physical attractiveness, the more physical intimacy was displayed
- Feingold carried out meta analysis of 17 studies. Found significant correlation in ratings of attractiveness between partners. Very valid and support of matching hypothesis as it looked at actual partners.
explain Walster’s ‘computer dance’ to test the matching hypothesis
- a ‘computer dance’ was advertised for students at US university. 177 males, 170 females randomly selected from those with tickets
- when they collected tickets, 4 students rated each participant on physical attractiveness
- participants completed questionnaires to asses characteristic and told these would be used to allocate an ideal partner for the dance
- paring was actually done randomly
- during a break, participants completed questionnaires about their date
- found that participants responded more positively to physically attractive dates, regardless of their own physical attractiveness
- they were more likely to arrange dates with them
- results did not support matching hypothesis
one major ethical problem with the computer dance study
- deception
- participants didn’t realise they were being rated on attractiveness
- didn’t realise matching was actually done randomly as they were told their date would be there ideal partner
a reason why the computer dance study didn’t confirm the matching hypothesis
- the measure of attractiveness was unreliable. The raters only had a few seconds to do so
- the design had reassured participants that they had been matched by computer, this would give false confidence in asking someone ‘out of your league’ for a date after the dance
- in life there are not such assurances. The set up was deceptive and not valid
Taylor’s research to contradict the matching hypothesis
- studied the activity logs of online dating site for choices people made for real dates
- contrary to the matching hypothesis, online dangers sought meetings with people who were more physically attractive than them
- however, this may only be because it wasn’t face to face so daters had more confidence
- although this may be different to how people behave in person, it does show the amount that physical attractiveness is placed on attraction
explain the individual differences that some people don’t put much importance on physical attraction
- Towhey. Males and females asked to rate individual based on their photograph and biological info
- participants completed MACHO scale which measures sexist attitudes and behaviour
- those who scored high on the scale were more influenced by physical attractiveness of their target when judging like ability
- challenges that idea that physical attractiveness is the most important for potential partners
Define self disclosure
- the voluntary sharing of private aspects of the self with another person
- e.g. Personal info, experiences, feelings
Types of self disclosure
- self disclosure given and self disclosure received
- ‘neutral’= preferences on music, films etc
- ‘intense’ = more personal. E.g previous sexual relationships
Explain sprecher’s aim and procedure of experiment on self disclosure
- to investigate whether reciprocal self disclosure was more influential in determining attraction than one sided listening
- 156 IS undergraduates. Unacquainted pairs 2/3 female-female , 1/3 male-female
- self disclosure task over Skype. Reciprocal condition - took turns in asking and answering questions. Extended reciprocal condition - a number of questions were asked by one and answered by their partner, then they swapped roles.
- after each interaction, they were asses for liking, closeness, perceived similarity and enjoyment of their interactions
Explain Sprecher’s findings and conclusion of his experiment on self disclosure
- those in the reciprocal condition reported more liking, closeness, perceived similarity and enjoyment of the interaction
- turn taking reciprocity more likely than extended reciprocity to lead to more positive outcomes
What was Miller and Collins research to support self disclosure
- supports idea that self disclosure plays important role in development and maintenance of relationships
- found that people who engage in intimate disclosures tend to be liked more than people who disclose at lower levels
Explain self disclosure on the internet
- been suggested that relationships on the internet involve higher levels of self disclosure and attraction than in face to face relationships
- explain by communication over the internet is often anonymous so people reveal more about themselves
- cooper and Sportolari ‘boom and burst’ . People reveal more about themselves so relationship becomes intense quickly (boom) but true knowledge of over person isn’t there to support relationship so is hard to sustain. (Burst)
Explain why self disclosure may be greater in face to face rather than online
- Knoo challenges assumption that there is more self disclosure between people online
- studies showed that members of a social group disclosed personal info more often face to face than online
- this could be because of the lack of intimacy on the internet as a place for self disclosure
Explain the cultural differences in patterns of self disclosure
- in the west, people typically engaged in more intimate self disclosure than the non western
- Americans disclose more than the Chinese
explain kerckhoff and Davis study on filter theory
- longitudinal study of 94 student couples in short term relationships in US
- each partner completed 2 questionnaires. one to asses similarity of attitudes, 1 to asses complimentary of needs
- 7 months later they completed another questionnaire to asses how close they were compared to at the start of the study
- spilt them up into long term and short term relationships. Found that for short term couples (less than 18 months) similarity of attitudes was the most significant predictor of how close the were
- for long term couples (more than 18 months) complimentary of needs was predictive of how close they felt to their partner
- this study helped them determine the levels of filters which people apply when choosing a partner
explain social demography for filter theory
- variables such as age, social background, location
- determine the likeliness of individuals meeting in the first place
- this reduces the range of people that are available for us to meet -more likely to meet people from the same location for example
- we find these people more attractive because we have more in common with them
explain similarity in attitudes in filter theory
- an individual’s psychological characteristics such as agreement on attitudes
- individuals who are very different from each other in terms of attitudes and values are considered not suitable so are filtered out from the field of possible long term partners
