Relationships Flashcards
What is the difference between natural selection and sexual selection?
Natural = characteristics that aid survival.
Sexual = characteristic that help genes to be passed on.
Define: human reproductive behaviour
Any behaviours which relate to opportunities to reproduce, such as partner preference, mate choice and ones sexual engagement.
Describe Anisogamy
The differences between female and male sex cells (gametes).
Females - egg, 400-500 (amount supplied), lifespan is approx 40yrs (puberty-menopause).
Male - sperm, unlimited supply, lifespan is from puberty to death.
Describe inter-sexual selection (between sexes)
- Preferred female mating strategy (quality>quantity).
- Females are choosier and select a mate based on whether they are genetically fit and resourceful.
- Females have higher investment in offspring and less chance of reproducing so want the best possible genes/resources.
Describe intra-sexual selection (within sexes)
- Preferred male mating strategy (quantity>quality).
- Males compete with eachother, want to mate with as many fertile females as possible so that their genes are passed on.
- Males have less investment in offspring so can afford to do this.
Outline Buss (1989): cross-cultural study investigating partner preference
Aim: to investigate of evolutionary explanations in human male preferences are based on values within different cultures/locations/religions.
Procedure: conducted survey of 10,047 participants across 33 countries and 5 islands. Mean age of participants were 23.05 years. Questionnaires answered were culturally relative and analysts were unaware of hypothesis.
Findings: 91% of samples, females values ‘good financial prospects’ more than men (Spain was exception). In all samples males preferred younger mates (with an average difference of 2.66 years) whereas females preferred an older mate.
Evaluate sexual selection and human reproductive behaviour
- Research support for evolutionary partner preference - Buss. Supports idea that both sexes have different preferences as they have different investments in the offspring.
- Research support for inter and intra-sexual selection - Clark & Hatfield. Shows that females are choosier than men when it comes to selecting a partner, males have evolved a different strategy to ensure reproductive success.
- Evolutionary theory fails to acknowledge other factors in HRB. Women’s greater role in workplace therefore no longer reliant on men for resources. Therefore mate preferences are no longer resource-oriented. Cultural factors come into play.
Outline Clark and Hatfield (1988): sexual selection
Proved inter and intra-selection through a study in which male/female psychologist students were sent across campus to ask students of the opposite sex a question.
‘I have been noticing you around campus. I find you to be very attractive. Would you go to bed with me tonight?’.
Not a single female agreed whereas 75% of males agreed, immediately.
Define: self-disclosure
Revealing personal information about yourself. Romantic partners reveal more about their true selves as their relationship develops.
Why is self-disclosure important at the start of a relationship and what type of information is typically disclosed?
At the start of a relationship, the more we learn about a partner, the more we seem to like/understand them.
Personal information - hopes, fears, interests, attitudes, likes/dislikes.
What is the social penetration theory? (Altman and Taylor, 1973)
- Self-disclosure is a key element of SPT. It is the gradual process of revealing your inner self to someone else.
- Penetrating more deeply into eachothers lives gains a deeper understanding. In romantic relationships it involves reciprocal exchange of info between intimate partners.
- This reciprocation displays trust, so as one partner self-discloses, the other also reveals sensitive info. More breadth = more depth (onion analogy).
Evaluate self-disclosure (between heterosexual and homosexual relationships)
- Research support into its importance and SPT - Sprecher and Hendrick, Laurenceau. Self-disclosure is important, it increases validity of SPT.
- Self-disclosure research can help people who want to improve communication in relationship. Increases intimacy and strengthens bond. Hass and Stafford, demonstrates the value of such insight.
- Prediction that self-disclosure will lead to more intimate romantic relationships is not true for all cultures. Tang et al, therefore a limited explanation of romantic relationships based on findings from Western (individualistic) culture only.
Outline Sprecher and Hendrick (2004) and its relation to Laurenceau (2005)
S and H found positive correlations between self-disclosure and relationship satisfaction.
L analysed diary entries and found that partners who believed they self-disclosed info with their partner reported higher levels of intimacy compared to those who didn’t.
Outline Hass and Stafford (1998) - Self disclosure has real life applications
Found that 57% of gay men and women in their study said that open and honest self-disclosure was the main way they maintained/deepened their committed relationships.
Outline Tang et al (2013)
Reviewed the research literature regarding sexual self-disclosure. Concluded that men and women in the USA (individualistic culture) self-disclosed significantly more sexual thoughts and feeling than men and women in China (collectivist culture).
Both these levels of self-disclosure are linked to relationship satisfaction in those cultures.
Define: Physical attractiveness
The degree to which a persons physical features are considered aesthetically pleasing or beautiful.
What type of faces are people most attracted to?
EVOLUTIONARY THEORY: Shackleford and Larsen (1997)
- Symmetrical - may be a signal of genetic fitness
- Neotenous (baby-face) - trigger a protective/caring instinct in males/females, a valuable resource for females wanting to reproduce.
Is physical attractiveness only important at the start of the relationship?
Not only important at the start of the relationship.
McNutty et al (2008) found evidence that the initial attractiveness that brought the partners together continued to be important for at least several years.
Describe ‘The halo effect’ (in relation to physical attractiveness)
- We have preconceived ideas about the personality traits attractive people must have, almost universally positive.
- Karen Dion and her colleagues (1972) summed it up: ‘What is beautiful is good’. Dion found that physically attractive people are consistently rated as more kind, strong, sociable and successful.
Define: ‘The halo effect’
How one distinguishing feature tends to have a disproportionate influence on our judgements of a persons other attributes.
Describe Matching hypothesis
Proposed by Walster et al (1966)
• Although physical attractiveness is desirable, common-sense tells us that we can’t all form relationships with the most attractive people.
• Our assessment of our own attractiveness plays a role in our choice of partner. We therefore choose a partner who is of similar physical attractiveness. Our choice of partner is basically a compromise, as we fear rejection.
Evaluate physical attractiveness
- Research support for halo effect - Palmer and Peterson. Positive attributes associated with attractive people. This has been applied to everyday life.
- Research support for matching hypothesis - Feingold. Supportive as the study looks at actual partners which is more realistic.
- Individual differences are a factor in physical attractiveness - Towhey. Physical attractiveness is not important for every individual, can be argued that the more sexist you are the more important it is to you.
- Research contradicting matching hypothesis - Taylor et al. Level of attractiveness is not considered when making decisions about who to date online.
Outline Towhey (1979) - individual differences in physical attractiveness.
Asked male and female participants to rate how much they would like a target individual, based on their photograph and some biological info.
Participants also completed a questionnaire, the MACHO scale - designed to measure sexist attitudes/behaviours.
Found that those who scored high on the scale were more influenced by the physical attractiveness of the target when making judgements of likeability.
Outline Feingold (1988) - supports matching hypothesis
Carried out a meta-analysis of 17 studies and found a significant correlation in ratings of attractiveness between romantic partners.
