evolutionary explanation
Sexual selection?
our preferences are evolved adaptations
- evolutionary explanation of partner preference
- attributes / behaviour that increase reproductive success are passed on + become more frequent over generations of offspring
- describes how evolution has shaped us to provide a mating advantage through intrasexual / intersexual selection
Anisogamy?
- refers to difference between male + female sex cells
- male gametes: small + mobile + many produced over longer time
- female gametes: large + static + limited fertililty as only limited time of production
- = no shortage of fertile males but fertile females are ‘rarer resources’
- gives rise to 2 types of sexual selection
2 types of sexual selection:
1.Inter- sexual selection
- when males compete for the attention of a female
- females chooses from available potential mates (males) according to attractiveness
- the female plays an active role, chosing her mate
- according to attractivness + biology
inter-sexual selection + human reperoductive behaviour
Robert trivers
- choosiness
- both sexes are choosy as they both stand to lose if they invest resources in substandard partners
- but the consequences of making a wrong partner choice are more serious for female = pays for her to be especially selective
- therefore female’s optimum mating stratergy is to select a genetically fit partner who is able to provide resources
inter-sexual selection + human reperoductive behaviour
Ronald Fisher
- Runaway process: sexy son hypothesis
- genes present in today’s generation are those that enhanced reproductive success
- women will mate with men they find “sexy”
- = their son will then inherit this “sexy” trait = higher reproductive success for later generation
Evidence for inter-sexual selection
- Buss + Schmitt
- asked men+women how many partners they would ideally want over next 2 years + over lifetime
over next 2 years (average) :
- men = would like 8 partners
- women = 1 partner
over lifetime (avergae) :
- men = 18
- women = 4-5
- Clark + Hatfield’s
- sent males+female students out + made them ask others “I have been noticing you around campus, i find you attractive would you go to bed with me tonight?”
- 0 females agreed
- 75% males agreed
2 types of sexual selection:
- Intra-sexual selection
- when males compete (often aggressively) + the winner is rewarded with the female
- the female is passive in this process
= she doesn’t choose her own mate
= leads to dimorphism
intra-sexual selection + human reperoductive behaviour
Dimorphism
- sexual dimorphism = difference in form between sexes = males + females look different
- in physical competetion between males for mates = size matters = larger males have advantage + more likely to mate
- dimorphism suggests that males are competing for the attention of females + females do the choosing
intra-sexual selection + human reperoductive behaviour
Aggressive behaviour
- males may benefit from behaving aggressively in order to acquire fertile females + protect them competing males
- = selection of aggressivness in males
intra-sexual selection + human reperoductive behaviour
preference for youth + fertility
- In females, youthfulness is selected because males have preference to mate with younger more fertile women
- eg females with large waist-to-hip ratio
Supporting evidence
Cunningham
- found that men are attracted to features associated with young children
- large eyes
- small noses + chins
evaluation for
Evolutionary explanations for Relationships AO3
- Supporting evidences
- Ignore social + cultural influences
- Evolutionary reductionism
- Emphasise the differences in what males and females look for in a potential partner
1.
Supporting evidences
- supporting evidence for intra-sexual selection’s theory that states that males compete for fertile female + have preference for youth + fertility
- Cunningham found that men are attracted to features associated with young children (eg large eyes + small noses + chins)
- Validates intra-sexual selection as shows that in females, youthfulness is selected because males have preference to mate with younger more fertile women
- making the evolutionary explanation for relationships more credible + furthers our understanding into what affects mating preferences in relationships
2.
Ignore social + cultural influences
- outdated
- Evolutionary explanations ignore social + cultural influences.
- For the past 100 years, Western societies have experienced significant changes in terms of gender
equality + women’s independence - These changes mean that women in modern Western societies may no longer be looking for a man to provide them with resources + other qualities in a mate become more important
- This makes evolutionary explanations limited, as they only explain human mates’ choice in terms of evolutionary adaptiveness, ignoring other important factors, such as culture + social norms.
3.
Evolutionary reductionism
- Evolutionary explanations of relationships suffer from
evolutionary reductionism, as they argue that strategies for choosing a mate are the result of genetic inheritance + a striving for reproductive success. - However, this is not always as straightforward in real life, where individual differences in partner’s choice play a huge part
- For eg evolutionary explanations fail to account for
homosexual relationships where choice of partner clearly does not result in reproductive success + so doesn’t have an evolutionary advantage
4.
Emphasise the differences in what males and females look for in a potential partner
- Furthermore, evolutionary explanations of mate preference also emphasise the differences in what males + females look for in a potential partner
- This exaggeration of the differences between the genders is known as an alpha bias + the differences between males + females may be overstated
- It is plausible to argue that males + females actually look for similar characteristics, such as loyalty + kindness, and such characteristics are not reported in the research,
which tends to look for clear differences.
Facttors affecting attraction
self-disclosure
- Revealing personal information about yourself
- Romantic partners reveal more about their true selves as their relationship develops
- These sef-disclosures about one’s deepest thoughts + feelings can strengthen a romantic bond when used appropriately
Social penteration theory of how a relationship develops
- self disclosure is a major concept within Altman + Taylor’s social penteration theory
- Revealing your inner-self to someone else
- Reciprocal exchange of information between intimate partners
- Builds trust
- Penetrate more deeply into each others lives
Breadth + debth of self disclosure
- According to Altman + Taylor, self disclosure has 2 elements: breadth + debth
- As both of these increase, romantic partners become more committed to eachother
- When we first meet someone, the info we reveal is more ‘superficial’ and ‘low-risk’ as afraid to reveal too much info straight away and threatening the relationship
- As relationship develops, self-disclosure becomes deeper
Recpricoty of self-disclosure
- For a relationship to develop + increase in breadth + debth there needs to be a reciprocal element to disclosure
- Once disclosing info about true self to partner, partner will hopefully respond in a way thats rewarding, with empathy / own intimate thoughts + feelings
- So there is a balance of self disclosure between both partners in successful romantic relationship = increase feelings on intimacy + deepen relationship
evaluation for
self-disclosure + social penteration theory AO3
- supporting evidence
- Methadological issues w SE
- Reductionism
- culture bias - ethnocentric
Real-life application - self-disclosure - main way gay men + women maintained + deepened their committed relationships
1.
Supporting evidence
- Altman + Taylor’s social penetration theory has supporting evidence from Sprecher + Hendrick
- They found a positive correlation between self disclosure, satisfaction + high levels of intimacy
- This increases our confidence in the validity of the
theory that self disclosure leads to more satisfying relationships.
2.
Methadological issues with SE
- However there are methodological issues with the SE for the social penetration theory as most of the research is only correlational.
- Whilst we can assume that self disclosure creates more
satisfaction we can not conclusively claim that as causation has not been established = we do not know if self disclosure increases satisfaction or if satisfaction increases self disclosure - Cause + effect can not be established
- Therefore its necessary to consider that other factors
could explain satisfaction in relationships for eg similarities in values and/ or monetary gifts
3.
Reductionism
- The social penetration theory reduces relationship satisfaction to a single factor = claiming that self-disclosure is most important in relationship formation
- The social penetration theory ignores many other aspects of romantic attraction, such as physical attractiveness, similarity of attitudes + complementarity
- However this does not mean they are any less important = limits the theory = less valid + credible
- Suggests further research should investigate couples individual experiences using a more holistic approach which will ultimately further our understanding into how romantic relationships are formed
