Define sexual selection in the evolutionary explanations for partner preferences
Sexual selection is a special form of natural selection in which the exes acquire distinct forms either because the members of one sex chose mates with particular features or because int he competition for mates among the members of on sex only those with certain traits succeed. These genes which code for these characteristics will be selected and passed through generations
Outline the human reproductive behaviour in the evolutionary explanations for partner preferences
Sexual selection therefore explains why some characteristics that may appear disadvantageous to survival are passed on through generations, and this is because they confer an advantage in human reproductive behaviour , ie. selecting in partner
Give an example of the human reproductive behaviour in the evolutionary explanations for partner preferences
For example, Darwin was fascinated by the flamboyant tail to the peacock as it appears to serve no purpose in terms of survival, and may actually be a handicap as it makes it more difficult for the bird to escape from predators. The sexual selection explanation is that, peahens are attracted to it, possibly because it signals the male’s ability to survive despite the large cost imposed by his fancy plumage. As a result, males with longer, more brightly coloured tails would then pass this characteristic on to the next generation. Over many generations, peacock’s tails would become more and more flamboyant because of this female preference. Thus the peacock’s tails gives an advantage in terms of mating despite beign a disadvantage in terms of survial
Define anisogamy
It refers to the differences between male and female sex cells, also known as gametes. In humans, male gametes, sperm, are very small, highly mobile, created continuously in vast numbers from puberty to old age , and do not require a great expenditure of energy to produce
Outline the consequences of anisogamy
The consequences of anisogamy is that there is no shortage of fertile makes but a fertile female is a rare ‘resources’. This has led to there being different types of sexual selection, as well as there being clear differences between men and women’s mating strategies
Outline the two types of sexual selection
There are TWO types of sexual selection:
* INTRA-SEXUAL selection which is the evolution of traits which allows males and females to gain an advantage over members of the same sex during mate competition
* INTER-SEXUAL selection which is the evolution of traits which are valued as attractive by members of the opposite sex
Explain how the types of sexual selection links to the evolutionary explanations for partner preferences
Although we see characteristics and strategies which are a result of both intra and inter sexual selection in BOTH males and females, anisogamy has largely led to females being the more choosy sex, whereas males tend to compete over mates.
Therefore we tend to see that males’ preferred mating strategy is a result of INTRA-SEXUAL
selection, referring to the competition between (intra) males to be able to mate with a female,
and females’ preferred strategy is INTER-SEXUAL SELECTION as they can be choosey when it
comes to selecting a mate.
Explain why males favour intra-sexual selection as a mating strategy and how this influences their reproductive behaviours
It provides an advantage in same sex competition for mates. For a male to ‘win’ the competition his goal is to mate with as many females as possible in the hope that they all be able to carry their offspring.
Males show preferences for youthful and attractive physical traits in a female partner because they are signs of fertility so will increase their chance of reproductive such as:
- Hip to waist ration = 0.8
- Looking for facial symmetry
- Neo-natural eyes
They show a preference for short term relationships to increase the chances of reproduction this leads to sexual dimorphism
How do males benefit from behaving aggressively
As noted, males may sometimes benefit from behaving aggressively, in order to compete with same-sex rivals and
show a woman that they can take care of her and protect her. It was also mentioned though that men may ‘think’ in
a certain way, this could be linked with JEALOUSY – as a result of these evolved behaviours, men tend to become
more jealous of SEXUAL INFIDELITY, because with little investment into a child, they fear CUCKOLDRY – which is
the fear of investing parental effort into offspring which is not genetically their own (Buss, 1992).
Explain why women favour inter-sexual selection as a mating strategy
As females have much fewer opportunities to reproduce, due to the laws of anisogamy, her investment in offspring is substantial in comparison to males.
Therefore a females optimum mating strategy is QUALITY over QUANTITY, and she will be attracted
to traits which indicate GENETIC SUITABILITY, as well a partner who is willing and able to provide RESOURCES.
How does inter-sexual selection affects women’s reproductive behaviours
Signs of Fecundity (ability to reproduce)) and genetic fitness
Women look for the physical features in a partner such as : good resources like economic and financial security, good genes like height, weight, good health, etc.
This is because they need a partner that will take care of them and their offspring because of the physical investment that women put into that offspring
A preference for partner who can provide resources and protection. This is because they need a partner who can provide and protect and care for them and their offspring when they have deeply invested in the child
Outline the Female preference for an evolutionary explanations for partner preferences
Females’ preference for a fit male has led to what Ronald Fisher (1930) proposed as the RUNAWAY PROCESS in his sexy sons hypothesis. This means these traits can be passed onto the child/ offspring which will increase the health of the offspring. This leads to the runaway process which the exaggeration of the physical traits in a male in a specifies as a result of female drive
Therefore sexual selection has heavily influenced REPRODUCTIVE BEHAVIOUR and led to clear differences between males and females partner preferences. Other than specific mate preferences though, males and females also differ in terms of RELATIONSHIP PREFERENCES and indeed what causes JEALOUSY.
Evaluate the Evolutionary explanations for partner preferences
There is a range of evidence which offers a degree of support for sexual selection and how it has influence on reproductive behaviour and mate preferences. For example Buss (1989) provided cross-cultural research related to anisogamy which supports sex differences in partner preferences and mating strategies. He carried out a survey of over 10,000 adults in 33 countries. He asked questions relating to a variety of attributes that evolutionary theory price predicts are important in partner preferences. He found that females placed greater value on resource related characteristics than males did, such as good financial prospects and ambition. Males valued physical attractiveness and youth more than females did. This is a strength to the research as the findings reflect consistent sex differences in partner prefers and supports the prediction for the sexual selection theory
However, a theoretical weakness with the evolutionary explanation is that it provides a reductionist account of sexual selection and could be accused of being undervaluing the impact of contemporary social and cultural factors. Despite offering a relatively parsimonious explanation, evolutionary theory reduces reproductive behaviour to a simple, evolved biological mechanism and thus overlooks social and psychological factors that can equally account for differences in sexual selection. Additionally, it does not take into account that contemporary factors can influence reproductive behaviour. For example Contemporary Lad culture may explain why young males are more interested in short term one night stands as this may reflect a possible desirable position within society. In addition, the reinforcement received from this behaviour through admiration from peers will only serve to maintain this behaviour in the future, so operant conditioning can also offer an explanation. Therefore, a more holistic theory would recognise the complexities of human reproductive behaviour, in particular the social and cultural purposes they serve
In addition, sexual selection is incomplete as it cannot explain all human reproductive behaviours. For example, sexual selection struggles to explain homosexual relationships and behaviours as these are not underpinned by reproduction, There must therefore be other factors which influence human reproductive behaviour. However, there have been some notable similarities found between partner preferences in both heterosexual and homosexual relationships. Such as in heterosexual relationships, personal advertisements in newspapers can be a revealing source of information about what men and women offer to potential same sex partners and what they seek in return. Gay men appear to desire specific physical attributes in a partner such as attractive face and athletic body and may value many of the status symbols such as well paid or masculine careers, that go with the male role in Western Culture (Davidson, 1991). So one might conclude that even though theories where original tested and looked on heterosexual couples, the same theories apply and partner preferences apply in heterosexual relationships
Define self disclosure in the factors affecting attraction in romantic relationships
Self disclosure was first used by clinical psychologist Sidney Jourad (1971). It refers to the extent to which a person reveals personal information about themselves- their intimate thoughts, feelings and experiences to another person. It is an important process in the development of a romantic relationship. With greater discourse leading to greater feelings of intimacy
Outline the norms of self disclosure in the factors affecting attraction in romantic relationships
With self disclosure their are expected norms, for example, there is a norm that people should engage in only a moderately personal level of self-disclosure in the early stages of a relationship Derlega & Grzelak (1979) suggests that these should be neither so personal that the disclosure appears indiscriminate for disclosing them to a relative stranger. The norm of reciprocity governs much of our social behaviour.. As Reis and Shaver point out, for a relationship to develop, as well as an increase in depth and breath there needs to be a reciprocal element to disclose
Outline the role of reciprocity of self-disclosure and it link to social penetration theory
As Hamy Reis and Phillip Shaver point out, for a relationships to develop, as well as an increase in depth and breath there needs ton be a reciprocal element to disclose
Outline the different types of self disclosure
There are different types of self disclosure as Sperecher (1987) found that disclosure of experiences of personal disappointments and information about previous sexual relationships, have a greater influence on relationships satisfaction than more ‘neutral’ types of self-disclosure. This is because once you have decided to disclose something that reveals your true self, hopefully your partner will respond in a way that is respectful, with empathy and also their own intimate thoughts and feelings.
Evaluate the self disclosure as a factor affecting attraction in romantic relationships
A strength is that there is a wealth of support from research studies. The previous research provides supportive findings of the importance of self-disclosure as a factor affecting attraction in romantic relationships. Such supportive findings increase our confidence in the validity of the theory that self-disclosure leads to more satisfying relationships. Collins and Miller (1994) provided further evidence with their meta-analysis. They concluded that self-disclosure plays a central role in the development and maintenance of romantic relationships. They found that people who engaged in intimate disclosures tended to be liked more than people who disclose at lower levels, and people like others as a result of having disclosed to them. Collins and Miller also found that the relationship between disclosure and liking was stronger if the recipient believed that the disclosure was only shared with them rather than being shared indiscriminately with others. Therefore demonstrating that self-disclosure is a factor which affects attraction in the early stages of a relationship
However, the role of self-disclosure is different across cultures. Culture differs in the extent to which various topics are considered appropriate for conversation. In the West, people typically generally engage in more intimate self-disclosure than do non-Westerners. Cultural norms also shape how comfortable men and women are in self-disclosing. For example Nakanisi (1986) found that Japanese women prefer a lower level of personal conversation than do Japanese men. This is opposite to the self-disclosure patterns typically found in the West, where women prefer more disclosure than men. Self-disclosure theory is therefore a limited explanation of romantic based relationships, based on findings from Western cultures which are not necessarily generalizable to other cultures.
Another strength of the study is the real-life application of the self-disclosure theory. The theory can be applied to couples who want to improve communication in their relationships and thus can use self-disclosure to strengthen their bond. It was found by Hass and Stafford that 57% of gay men and women in their study said that honest self-disclosure was the most vital way they deepened their relationships. This could be vital for partners who struggle to communicate in aiding their relationship. Having said this, the study used homosexual relationships, not heterosexual ones, displaying that there may be differences between certain relationships and comfort levels felt in both. Therefore, a strength of the study is its applicability to real life, although it does not look at both homosexual and heterosexual relationships.
Define physical attractiveness as a factor affecting attraction in romantic relationships
Physical attractiveness refers to what people find appealing about a person’s face and body. Despite individual differences, there is a general consensus on what is physically attractive. This could be explained through evolution.
Give some examples of the physical features that affect physical attractiveness
Physical features considered attractive are often signs of fertility or genetic fitness, for example facial symmetry, waist-to-hip ratio, etc. This would be expected to be an important factor in the formation of relationships.
Outline the ‘halo effect’ in physical attractiveness as a factor affecting attractiveness
The halo effect believes that physical attractiveness may also play an important role in forming relationships with people because of the preconceived ideas we have about the personality traits that attractive people must have and how positive these are.
The halo effect: Dion et al (1972) found that physically attractive people were rated highly on characteristics such as kindness, strength, sociability and other positive traits. Therefore, people who are attractive physically are more likely to be treated more positively, as others tend to think positively of them. This is referred to as the halo effect- one characteristic (physical attractiveness) has a disproportionate effect on other judgements about a person.
Outline what is meant by the matching hypothesis in physical attractiveness
The matching hypothesis is a theory of interpersonal attraction which argues that relationships are formed between two people who are equal or very similar in terms of social desirability.
Give a piece of research into physical attractiveness as a factor affecting attraction
Walster et al (1966) suggested that people choose romantic partners of a roughly equivalent level of attractiveness to themselves. This involves being able to make an accurate judgement about their own attractiveness level. There may be a difference between what a person would like, and what they would ‘settle for’ in a relationship. He conducted research based on the Computer Dance study In 1966. The procedure is that male and female students were invited to dance and were rated for physical attractiveness by objective observers at the start and also completed a questionnaire about their personality self-esteem and this information would be used by a computer to decide their partner for the evening. They found that the hypothesis was not supported and that most liked partners were alps the most physically attractive rather than taking their own level of attractiveness into account. In conclusion we tend to seek and choose partners whose attractiveiness matches our own. Therefore choice of partner is a compromise however it does not show the importance of physical attractiveness as a factor
Evaluate physical attractiveness as a factor of affecting attraction
A strength is the amount of research support for the different aspects of physical attractiveness and their impact on romantic support. There is research supporting the halo effect such as Dion et al (1972). He found that attractive people are consistently rated as successful, kind and sociable when compared with unattractive people. This means that we not only believe that good-looking people are more physically attractive, we expect them to have other desirable characteristics as well and tend to behave more positively toward them. These findings have an implication for the support for the halo effect.
Yet, cultural influences could actually support the importance of physical attractiveness’ importance. This is due to the fact that research into what is deemed physically attractive is remarkably consistent across cultures. Cunningham et al. (1995) found that female features of large eyes, prominent cheekbones, small nose and high eyebrows were rated as highly attractive by white, Hispanic and Asian males. The halo effect also seems to be a universal behaviour, Wheeler & Kim (1997) found that Korean and American students judged physically attractive people to be more trustworthy, concerned for other people, mature and friendly. So it seems that the physical attractiveness stereotype is just as strong in collectivist cultures as it is in individualistic cultures.
A further limitation of physical attractiveness as a factor affecting attraction is complex matching. Sprecher & Hatfield (2009) suggest a reason why research often fails to find evidence of matching in terms of physical attractiveness – people come to a relationship offering many desirable characteristics, of which physical attractiveness is only one. A person may compensate for a lack of physical attractiveness with other desirable qualities such as a charming personality, kindness, status, money and so on. Sprecher & Hatfield refer to this tendency to compensate for a lack of physical attractiveness by offering other desirable traits as ‘complex matching’. In this way people are able to attract partners far x more physically attractive than themselves by offering compensatory assets, for example, an older, wealthy man may pair with a younger, attractive woman.
Define the filter theory as a factor affecting attraction in romantic relationships
When choosing a partner, people start by looking at the options that are available. However, not everyone who is available will be equally attractive, so people usually apply some criteria to narrow down the ‘pool of availabilities’ to make sure they choose the right person
Discuss Kerchhoff and Davis role in the factor affecting attraction in romantic relationships
Based upon a longitudinal study of the experiences of dating couples Alan Kerckhoff and Keith Davis discovered that various filtering factors were prominent at different stages of the partner selection process as potential partners tried to find the ‘best fit’ between themselves and a future romantic partner. Rather unsurprisingly, this theory became known as the filter theory of relationships.
Kerckhoff & Davis’ filter theory of attraction suggests that we choose romantic partners by using a series of filters that narrow down the ‘field of available’ into a ‘field of desirables’. According to Kerckhoff & Davis there are three main factors that act as the filters in this process, and each are prominent at different stages of partner selection.
