Outline sexual selection
Darwin 1871
- evolutionary explanation of partner preference
-selection of characteristics that aid successful reproduction are passed onto offspring and trait with become exaggerated over generations
Outline examples of sexual selection
aggression: (in males) is adaptive because it provides an advantage for males over competitors for reproductive rights
fertility: (in woman) narrow waist and large hips
Define Anisogamy
For example : the differing size of gametes and energy invested in their production whether they are static or mobile , and intervals in which they are produced
men: small gamete , highly mobile , created continuously in vast numbers from puberty and don’t need energy to be produced
female: large gamete , highly immobile , provided at intervals for limited number of fertile years and require significant investment of energy
Outline Inter-sexual selection
evolutionary standpoint: enables the high quality of her offspring
Outline an example of inter-sexual selection
Fisher’s sexy son hypothesis- suggests that through a female choosing to mate with an attractive male , her son will also grow to be attractive “Sexy”
: thus son more likely to have evolutionary advantage of attracting females
Outline Intra-sexual selection
-leads to dimorphism : physical difference between male and female sexes
According to Anisogamy, the male’s optimum reproductive strategy is to mate w/ many fertile females = behavioural consequence of having a preference for symbols of youth/fertility.
Outline examples of intra-sexual selection
males behaving aggressively and being
protective of their female (reducing the likelihood that she will be impregnated by another competing male)
being larger (and so more sexually desirable to women), as well as possessing certain facial and physical characteristics
(e.g. strong jawlines and broad shoulders).
eval points for evolutionary explanation
LIMITATIONS
cannot explain partner preferences of gay men and lesbian woman
-overlooks influence of social and cultural factors on partner preference
STRENGTHs
evidence supporting that females are more selective when it comes to potential mates
cp: sexual statergies theory : both men and woman are choosy
Evaluate limitation of the evolutionary explanation to partner preferences
( hetereonormativity)
cannot explain partner preferences of gay men and lesbian woman :
- mainly bc : homosexual relationships are not assessing genetic fitness (otherfactors)
-Lawson et al looked at “personal ads” placed by hetero and homo men and woman & found preferences in in homo men and women differ from hetereo (men emphasised attractiveness and women : resources)
- cant generalise : heteronormativity bias
Evaluate limitation of the evolutionary explanation to partner preferences
( social and cultural )
overlooks the influence of social and cultural factors on partner preference
-partner preferences have dramatically been influenced/adjusted by rapid changing social norms (century)
-these develop faster than evolutionary timescale implies : come ab due to cultural factors
- womans greater role in workplace means they are no longer dependant on men to provide : argued that this Social change has had lead to change in womans preferences for men (not resource orientated)
-combination of cultural and evolutionary (interactonist) - can be limited etc if does not account for both
Evaluate strength of evolutionary explanation for partner preference
(females “choosy”)
evidence supporting that females are more selective when it comes to potential mates:
CP : reductionist : sexual statergies theory argues both men and woman are choosy : evolutionary pressure influences are much more complex taking into account context of reproductive behaviour
Outline the filter theory for a factor in affecting attraction in a romantic relationship
kerckhoff and davis 1962
- we are initially exposed to a “field of availables”
-in order to form relationships field must be narrowed to “field of desirables” depending on 3 filters:
- social democracy
- similarity in attitudes
- complementarity
-importance of each filter depends on whether relationship is LT or ST
Outline the social democracy filter
Outline the similarity in attitudes filter
Outline complementarity in attitudes filter
Eval points of filter theory
STRENGTHS :
- research evidence from Winch 1958
CP: temporal validity : social change :still applicable today?
LIMITATIONS:
- reductionist : abusive relationship
-suffers from cultural bias
- montoya - meta analysis - may percieve to be more similar
Evaluate a strength of the filter theory as a factor for affecting attraction
research evidence initial development of relationships
CP: may lack temporal validity : research of 1958 : many social changes since that time : e.g social media etc may have a greater influence
Evaluate limitation of the filter theory (reductionist)
Reductionist
- simplifies complex phenomena of romantic relationships into a 3 step filter theory : ignores
Evaluate a limitation of filter theory (cultural bias)
suffers from cultural bias
- most research taken from individualist cultures : more likely to value free choice in relationship : desirability : individual preference
-cannot apply to collectivist cultures: marriage more likely to be arranged : partners cannot apply individualist filters on who their future partner will be
Evaluate a strength of the filter theory
actual similarity matters less in a relationship than whether partners perceive or believe themselves to be similar
-therefore : can interpret : partners may perceive greater similarity as they become more attracted to one another
-perceived similarity may be an effect of attraction not a cause : not predicted by the filter model
Define self disclosure
-revealing personal information about yourself
-romantic partners reveal more about their true selves as their relationship develops
-self disclosure about ones deepest thoughts and feelings can strengthen a romantic bond when used appropriately
Outline the social penetration theory (self-disclosure)
Altman and Taylor proposed this theory
-important to be selective about what one chooses to disclose
Outline the breath and depth of self-disclosure
2 elements of self disclosure
Onion anaology
- as relationship progresses, more layers of the onion is removed
-info disclosed upon first is superficial and “on the surface” and “low risk”
- kind of information we would disclose to strangers, colleagues etc.
-Revealing intimate details about oneself at the beginning of a relationship may be detrimental effects
e.g. revealing ‘too much information’. TMI!
-As relationship progresses : self disclosure becomes deeper : progressively removing + layers revealing our true selves
Outline importance of reciprocity in self disclosure
when revealing more layers:disclosing something that reveals your true self
-partner must respond in a way that is rewarding e.g empathy and also their own intimate thoughts etc
balance of self disclosure in a relationship : successful relationship : deeper relationship
