Relationships Flashcards
(55 cards)
what is inter sexual selection?
Members of one biological sex choose mates of opposite sex, this causes attractive traits to survive
what is the evolutionary theory of sexual selection?
Purpose of attraction is to maximise on passing on genes
So, people are attracted to those that will increase reproductive success
Evolutionary theory predicts difference in mate choice between genders, as men and women face different evolutionary pressures in E E A
Men/women have different partner preferences due to biological differences.
biological differences between males and females?
females Low potential reproductive rate because:
Produce few large/energy rich eggs
Only fertile for 72 hours per month
Fertile from puberty lo menopause
Have to endure pregnancy/lactation
Max 1 offspring per 2 years.
characteristics prefered by males?
-young, fertile women
-symmetrical face
-not choosy (bad choice isn’t costly)
characteristics preferred by females?
-resources
-ambition/intelligence
-older males
-cost of bad choice is costly
what are 4 evaluation points?
+: nature more significant than nurture when choosing mate- studied 37 cultures, similar mate choices suggesting genetics rather than culture.
-: didn’t distinguish between preferences for long/short term relationships – Kenrick asked people to rank various attributes to 4 levels of intimacy.
- long-term: intelligence more important for men/women
- short-term: intelligence matters less especially for men
Findings to buss experiment not valid across all situations
-: evolutionary theory is reductionist – reduces social behaviour to sexual behaviour then reproductive strategy. Deemphasises role of other factors such as the culture.
-: evolutionary theory is deterministic – if biology determines Mate choices, then we have no choice about how respond to others. Biological determinism used as an excuse for unfaifulness in relationships
what is intra-sexual selection?
Competition within a sex.
Males compete with each other as females are more choosy; thus females become a limited resource, for which males must compete.
what is sperm competition?
In animals many males mate with each female, thus a female will have the sperm of several males in her reproductive tract at once.
Leads to selective pressure on males to increase number of sperm in each ejaculation so it can compete with rival sperm.
what are 3 evaluation points of intra-sexual selection?
-larger the testes size, the greater the competition.
-testes of humans are larger than gorillas (live in signal male harems), but smaller than chimpanzees (where females mate with many males).
-supports evolutionary theory- there has been intrasexual selection in past resulting in evolution of larger testes. Suggests females are more promiscuous than first suggested.
what is the importance of physical attractiveness?
Buss (evolutionary theory)- showed men in particular place great importance on phy. Attractiveness when choosing mate.
-evolutionary psychologists argue attractiveness is indicator of womens health/fertility.
-phy. Attractiveness less important for females in long-term relationship than short term.
what is a study supporting phy. attractiveness?
A: investigate wether there was sex differences in importance of phy. Attractiveness.
P: both partners in couple had attractiveness objectively rated at the start of study. Then asked to report material satisfaction 8 times over first 4 years of marriage.
F: objective ratings of wives attractiveness were + correlated to levels of husbands satisfaction. (True at start of marriage and next 4 years)
C: women find attractiveness less important as evolutionary theory suggests.
what is matching hypothesis?
People are attracted to those of similar attractiveness to themselves.
Although we want most attractive partner, the desire is balled by likelihood of rejection.
Neither partner would be comfortable with unequal matching in a relationship (insecurity)
Thus we settle for someone ‘in our league’.
what is contradictory evidence for matching hyp?
A: investigate if matching occurred in real life date choices.
P: studying activity log on dating site and identifying pairs of people that communicated with each other on the site.
F: website users more likely to arrange date with someone more attractive than them.
C: contradicts matching hypothesis, site users should settle for dates with people of same attractiveness to themselves- better chance of being accepted by partner.
what are 3 evaluation points for factors affecting attraction?
X- reductionist- theories emphasising importance of phy. Attractiveness = simplistic. Other factors involved in mate choice (personality).
X- individual differences in terms of importance of attractiveness- p’s asked to rate how much they liked person in a phot- phy. Attractiveness more important for p’s who had sexist attitude (measured by questionnaire). Phy. Attractiveness not important for everyone.
+: phy. Attractiveness important in forming relationships cross-culturally: white, Asian, Hispanic males despite being from different cultures rated females with small noses,large eyes, prominent cheekbones highly attractive.
Using attractiveness in choosing partner may be genetic. Biological not environmental.
what is self disclosure?
revealing personal info about yourself. Allows strengthening of bond.
what is the social penertration theory?
-gradual process of revealing your inner self to someone.
-reciprocal exchange of info between partners- one partner reveals personal info, displaying trust, to go further other partner must also reveal some personal info.
-eventually, romantic partners penetrate more deeply into each others lives.
what is the onion theory (breadth and depth)?
-breadth- ‘outer layer of onion’, revealing low risk info e.g., jobs, friends, childhood stories.
-if we reveal too much too soon, it may scare partner off.
-depth- happens over time (wider range of topics) personal, high risk info e.g.m, secrets.
as well as depth/ breadth, there needs to be reciprocity. Once you have disclosed something revealing you true self, partner should respond in rewarding/ empathetic way- leads to balance.
what are 4 evaluation points of self disclosure?
X: correlational- could be person in secure relationship can disclose more personal items, instead of disclosing items to make relationship secure. Can’t infer cause/ effect.
+: real life applications: hass and Stafford- 57% of gay men/women said self disclosure was main way they maintained/ deepened their relationship.
+:supporting research: sprecher and hendrick- strong + correlation between several measures of satisfaction/ disclosure among heterosexual couples.
+: valid: laurenceau et.al (diary entries)- self disclosure/ perception of self disclosure were linked to higher levels of intimacy in long term married couples
what is the filter theory?
‘field of availabilities’- the possible people we could have a relationship with.
-we filter out different potential partners for different reasons at different times.
-narrowed down to ‘field of desirabilities’ (people we consider as potential partners)
what is the social demographic model?
exerts its influence without us realising. People tend to mix with others who are similar in several ways. E.g., live in similar areas, go to school together.
-people from different backgrounds are rarely encountered.
-leading to small selection of similar people.
-creating ‘field of desirables’
-in this stage, social demographics more important than phys. Attractiveness.
what is similarities of values?
if couples share ideas/ values, communication is easier, causing attraction, leading to relationship.
-however if they think differently, share few views about the world, its likely the relationship wont progress.
-people with different values/ attributes are filtered out.
what is complimentarity of emotional needs?
how well 2 people fit together and meet each others needs.
-people who have different needs like the need to be cared for and the need to care work as they compliment each other.
-give 2 partners feeling that they form a whole.
what are 4 evaluation points of filter theory?
X: validity- in recent years, online dating has increased, changing process of forming relationships, reducing importance of social demographic variables.
X: cause and effect- suggested people find each other attractive as they are similar. However, its found partners become similar over time (emotional convergence)
X: beta gender biased- ignores fact men/women use different filters (buss cross-cultural study)- men filter using phys. Attractiveness, females filter using wealth/ resources. Ignores how cross-cultural relationships are formed (cultural bias) e.g., arranged marriages.
+: kerchoff and Davis- longitudinal study, couples together for more/ less than 18 months
-complete several questionnaires over 7 month period, reporting on attitude/ personality similarity.
-attitude similarity important for up to 18 months in relationships.
-after this, ability to meet each others needs becomes more important.
what is social exchange theory?
Economic theory-based on idea that relationships are like marketplace ( seek best deal).
Trading exchanging commodities
Satisfying relationships = high rewards / low cost for both parties.
Profit:
Profit = reward-cost
Thibault + Kelly – believed individuals motivated to maximise reward and minimise cost to gain best profit.
Rewards / cost are subjective
Cost E.g. – effort, financial cost, missed opportunities
Reward E.g. – being cared for, sex
