Relationships Flashcards
Sexual selection-
Evolutionary explanation of partner preference. Attributes or behaviours that increase reproductive success are passed on and may become exaggerated over succeeding generations of children.
Human reproductive behaviour-
Any behaviours which relate to opportunities to reproduce and thereby increase the survival chances of our genes.
Anisogamy-
Differences between male and female sex cells, male gametes (sperm) and female gametes (eggs or ova).
Inter-sexual selection-
Between the sexes.
Intra-sexual selection-
Within each sex. Preferred strategy of the male, quantity over quality, winner reproduces and gets to pass on to the offspring the characteristic that contributed to his victory.
Inter-sexual selection: Robert Trivers (1972)
The female makes a greater investment of time, commitment and other resources before, during and after the birth of offspring. The females want to find a genetically fit partner, leaving the males to compete.
Runaway process: Ronald Fisher (1930)-
A female mates with a male who has a desirable characteristic and that ‘sexy’ trait is inherited by her son. This increases the likelihood that successive generations of females will mate with their offspring.
David Buss (1989)
Support for anisogamy.
Survey of over 10,000 adults in 33 countries. He asked questions relating to age and other attributes that evolutionary theory predicts should be important in a partner. Female respondents needed resource-related characteristics (money) than men. Men valued good looks and chastity.
Clark and Hatfield (1989)
Support for inter-sexual selection.
Female choosiness is a reality of straight relationships. Male and female students were sent across a uni campus. They approached others with the questions, “I’ve been noticing you around campus. I find you to be very attractive. Would you go to be with me rn?” No female accepted the request, 75% of men did immediately.
Sexual selection criticism-
Social and cultural differences.
Bereczkei et al (1997) says social change has a consequence on women’s mate preferences as they no longer need a working man.
Chang et al (2011) compared partner preferences in China over 25 years and found that some had changed but others remained the same corresponding with huge social changes at the time.
Self-disclosure-
Revealing personal information about yourself.
Social penetration theory-
Altman and Taylor’s (1973) social penetration theory of how relationships develop. Gradual process of revealing your inner self to someone else, reciprocal exchange of information. As they disclose more, the penetrate more deeply into each other’s lives gaining trust.
Breadth and depth of self disclosure-
Altman and Taylor.
As breadth and depth increase, so does commitment. Breadth is narrow as many topics are off-limits early on in relationships.
Reciprocity of self disclosure-
Reis and Shaver (1988) say, for a relationship to develop, as well as breadth and depth there needs to be a reciprocal element to disclosure.
Self disclosure- Supports.
+Sprecher and Hendrick (2004), studied straight couples and found strong correlations between satisfaction and self disclosure.
+Laurenceau et al (2005) daily diary entries, found that self-disclosure was linked to higher intimacy levels.
+Hass and Stafford (1998) found 57% of gay men and women in their study said self-disclosure was that main way to keep a committed relationship (real-life application)
Self-disclosure
Criticisms.
-Increasing depth and breadth of self-disclosure does not help in all cultures. Tang et al (2013) reviewed the research literature regarding sexual self-disclosure and concluded men and women in the USA self-disclosure more sexual thoughts than those in China.
Physical attraction-
How appealing we find a person’s face.
Matching hypothesis, Elaine Walster-
Belief that we do not select the most attractive partner but, instead, are attracted to people who ‘match’ us in physical attractiveness.
Physical attractiveness- Shackelford and Larsen (1997).
Found that people with symmetrical faces are rated as more attractive because it may be a sign of genetic fitness.
Neotenous features-
People are attracted to faces with neotenous features (baby-face) because these trigger a caring instinct.
Physical attraction- McNulty et al (2008)
Found evidence that the initial attractiveness that brought partners together continued to be an important feature of the relationship after marriage, for at least several years.
The halo effect-
One distinguishing feature tends to have a disproportionate influence on our judgements of a person’s other attributes (personality).
Support for the halo effect-
Palmer and Peterson (2012), found that physically attractive people were rated as more politically knowledgeable and competent than unattractive people. Perhaps there are dangers for democracy if politicians are judges on attractiveness.
Criticism for physical attractiveness.
Some people do not attach much importance to physical attraction. Towhey (1997) asked men and women p/pants to rate how much they would target a person based on a picture and biographical info. The p/pants also did a questionnaire to measure sexist attitudes. He found that p/pants who scored highly on the scale were more influenced by physical attraction.
