Relationship 3 Flashcards
Darwin’s Sexual Selection A01
•natural selection: genes selected that promote survival
•sexual selection: promote successful reproduction eg peacocks tail
•adaptive characteristics: advantages over males
Anisogamy
•basis of human reproductive behaviour
•differences between female and male sex gametes
•sperm: small, mobile, vast numbers, not much energy
•eggs: large, static, limited number, investment of energy
Inter-sexual selection
•between sexes, strategies that males use to select females vice versa
•females prefer quality over quantity
•males prefer quantity over quality
Inter-sexual selection Trivers
•Trivers: females make greater investment of time& commitment
•consequences of wrong choice are more serious
•female optimum mating strategy is select genetically fit partner
•female preference determines which features are passed on to offspring’s, •increases attractive trait in male population over successive generations ( runway process)
Inter-sexual Fisher
•sexy sons hypothesis: genes we see today are those that enhanced reproductive success.
•eg female mates with male with desired characteristic who will inherit sexy trait and sons more likely to be selected by successive generations of female who will mate with her offspring’s
•preference for sexy trait is perpetuated
intra- selection
• within sexes, strategies between males to be the one that is selected
•competition between males, winner reproduces and characteristics contributing to victory are passed on
•dimorphism: differences in sexual organs, size matters
•females youthfulness selected
•behavioural consequence: favoured characteristics passed on that allow males to outcompete males
Sexual selection strengths
•evidence for specific role of female choosiness in heterosexual preferences, Clark and Hatfield: uni students asked to go bed, no female agreed, 75% males agreed, supports view that girls are choosier than males
(simplistic, length of relationship, lt=choosier, more complex)
•Buss survey over 10,000 adults in 33 countries, questions related to attributes that evolutionary theory predicts, females importance on resources, males valued attractive and youth, reflect consistent sex differences in preferences
Sexual selection limitations
•social and cultural influences underestimated, preferences influenced by rapidly changing social norms of behaviour
•homosexuality, cannot explain partner preference of gay ppl, not assessing genetic fitness, Lawson looked at personal ads placed by homosexuals, found that preferences differ like straight ppl
self disclosure
•revealing personal information about yourself, vital role beyond initial attraction, careful about what they disclose at least to begin with, used wisely can help course of love run smoother
social penetration theory
•altman and taylor’s theory of how relationships develop
•gradual process of revealing your inner self to someone else of giving away your deepest thoughts and feelings
•reciprocal exchange of info between intimate partners, to signal trust and the other person also revealing sensitive info
•increased disclosure means they “penetrate” more into each others life’s and gain greater understanding of each other
•basic feature since it’s difficult to hear one’s soul to a relative stranger
•by doing so the relationship has reached a certain stage where self-disclosure will be welcomed and reciprocated
breadth and depth of self disclosure
•2 elements= breadth & depth, increase= more committed to each other
•eg onion, disclose a lot at the start but superficial, low risk info revealed to anyone, narrow breadth bc many topics are off-limits in early stage to avoid response of TMI and threaten relationships
•relationship develops, self-disclosure becomes deeper, removing more layers to reveal true self and encompass a wide range of topics, things that matter the most
•eventually prepared to reveal intimate, high risk info eg painful memories, strongly held beliefs/ secrets
•depenetration: describe how dissatisfied partners self disclose less as gradually disengage from relationship
reciprocity of self disclosure
•Reis and Shaver: for relationship to develop as well as breadth and depth there needs to be a reciprocal element to disclosure
•once u disclosure your true self, hopefully your partner will respond in a way that is rewarding with emo that and also their own intimate thoughts
•there is a balance of self-disclosure between both partners in successful relationship, which increases feelings of intimacy and deepen relationship
Self-disclosure A03 strengths
•several predictions from S.P.T, Sprecher and Hendrick studied heterosexual dating couples and found strong correlations between measures of satisfaction and self-disclosure, those who self disclose were more satisfied and committed, Sprecher shows relationships are closer when disclosure is reciprocated
•can help people who want to improve communication, partners use self disclosure deliberately to increase intimacy and strengthen their bond, Haas and stafford found 57% of homosexual men and women said that open and honest self disclosure was main way to maintain and deepen relationship, if less skilled partner learn to self disclosure this could benefit relationship and deepens satisfaction and commitment, shows psychological insights can be valuable to help relationship problems
Self-disclosure A03 limitations
• not true for all cultures that increasing breadth and depth lead to more satisfactions, Tang reviewed sexual self disclosure and concluded US ppts self disclose significantly more sexual thoughts than Chinese ppts, despite lower levels of disclosure satisfaction were no different, limited explanation as based on findings on individualistic cultures not generalisable to other cultures
•self-disclosure is correlational but a correlation does not tell us if greater self disclosure creates more satisfaction as a conclusion only a casual link, alternatives are just as likely eg more satisfaction = more self disclosure or a third variable like amount of time spent together, so self disclosures may not cause satisfaction directly reducing the validity
explaining the importance of physical attractiveness
•Shakelford and larsen: people with symmetrical faces are rated more attractive bc honest signal of genetic fitness
•attracted to faced with neotenous (baby-face) features eg widely separated and large eyes, delicate chin and small nose bc trigger a protective/caring instinct
The halo effect
•matter bc we have preconceived ideas about the personality traits attractive ppl must have, almost universally positive •physical attractiveness stereotype- widely-accepted view of attractive people neatly summed up by Dion “what is beautiful is good”, attractive people are rated as kind, strong, sociable and successful, makes them more attractive so behave positively toward them- self fulfilling prophecy
•halo effect: distinguishing features tend to have disproportionate influence on our judgement of another persons attitudes eg personality
Research on matching hypothesis
Walster and Wlaster: look for partners similar to ourselves in physical attractiveness/ personality instead of most appealing. Walster= the computer dance
•procedure: students invited to dance, rated for physical attractiveness by objective observers and completed questionnaires where computer would decide their random partner
•findings: hypothesis not supported, most liked partners were also most attractive rather than taking their own level of attractiveness into account, however Berscheid replicated study but each ppt able to select partner from varying degrees, ppl chose partners matching attractiveness
•conclusion: seek and choose partner with matching attractiveness, eg a 6/10 would look for similar partner, choice of partner is a compromise-risk rejection in selecting most attractive so settle with those “in our league” physically
Physical attractiveness A03 strengths
•research support for halo effect, Palmer and Peterson found ugly people rated more politically knowledgeable and competent than leng ppl, powerful that persisted when ppts knew knowledgeable people had no expertise, implications for political process- dangers for democracy is politicians are judged as suitable for office bc they are physically attractive by enough voters
•evolutionary processes, Cunningham found women with large eye, prominent cheekbones, small nose and high eyes brows were rated highly attractive by white, hispanic and asian men, physically attractive is consistent across different societies, attractive features (symmetry) sign of genetic fitness so perpetuated similarly in all cultures (sexual selection), importance of attractive makes sense at evolutionary level
Physical attractiveness A03 limitations
•matching hypothesis not supported by real world research into dating, Taylor studied activity logs of dating site, real-work test as measured actual date choices and not merely preferences, online daters sought meeting with partners more attractive, undermines the validity of hypothesis as it contradicts central prediction
However, choosing individual for dating different to romantic relationships, Feingold carried meta analysis on 17 studies and found significant correlation in rating of physical attractiveness between partners, also seeking more attractive doesn’t mean you get them so dating selection may be fantasy as it is laboratory research, support for matching hypothesis
Filter theory
• kerckhoff and davis: compared attitudes and personality of studies in ST (18months) and LT relationship
•filter theory explains how’s relationships form and develop
•field of availables but not everyone is desirable
•main factors that act as filter to narrow down range of partner choices to field of desirables
