Relationships evaluation and studies (Lesson 1-4) Flashcards
Darwin (1871)
Sexual selection is about the selection of characteristics that aid successful reproduction rather than survival. Although successful reproduction would ultimately aid survival.
Buss (1993)
While men are fearful of partners being sexually unfaithful, females worry about emotional unfaithfulness due to a fear of their partner spending resources on other females.
Fisher (1930)
sexy sons hypothesis, females select attractive males as they will produce sons with the same features increasing their sons and their own reproductive fitness
Zahavi (1975)
Handicap hypothesis, females select males with handicaps, demonstrating superior genetic quality.
What are the strengths of evolutionary explanations for partner preferences?
Research support from: - Clark and Hatfield (1989), - Pawlowski and Dunbar (1999), - David Buss (1989)
What are the weaknesses of evolutionary explanations for partner preferences?
- Too simplistic (Buss and Schmitt (2016)), - Not considered social and cultural influences (Bereczkei et al (1997)), - Cannot explain homosexual preferences (Lawson et al (2014))
Clark and Hatfield (1989) (Research support for inter-sexual selection)
Sent m+f psych students out on a uni campus, approaching others with an offer to go to bed with them. 0% of females agreed and 75% of males agreed. Supports view that females are choosier than males
Pawlowski and Dunbar (1999) (Research support for inter-sexual selection)
Examined idea that older women do not disclose their true age in personal advertisements because men judge prospective females on age (due to fertility) True for women 35-50 to find high quality partners before menopause.
David Buss (1989) (Research support for intra-sexual selection)
Survey of 10,000 adults in 33 countries. Asked questions relating to evolutionary theory attributes. Females place greater value on resource related characteristics and males valued physical attractiveness and youth.
How are evolutionary explanations for partner preferences reductive?
It assumes one strategy is adaptive. There are other factors that might be relevant such as long term relationship. Buss and Schmitt (2016) argued its complexity.
Buss and Schmitt (2016)
Argue that both males and females who are looking for long term relationships are much choosier, looking for partners that are loving, loyal and kind.
How do evolutionary explanations for partner preferences underestimate social and cultural influences?
Partner preferences over the past century have been influenced by changing social norms of behaviour, developing much faster than evolution and have come about due to cultural influences like contraception.
Bereczkei et al (1997)
Women’s new role in the workplace means they aren’t dependent on men for financial support so their mate preferences have changes as they no longer rely on men being bread winners.
Why can’t evolutionary explanations for partner preferences explain homosexual preferences?
Because they aren’t looking for genetic fitness
Lawson et al (2014)
looked at personal ads by both heterosexual and homosexual individuals and found preferences differed.
Altman and Taylor (1973)
Social Penetration Theory - disclosures in a relationship become increasingly intimate as the relationship develops, it must be a reciprocal exchange
Reis and Shaver (1988)
For a relationship to develop their needs to be reciprocity
What are the strengths of self disclosure as a factor affecting attraction?
Research support for social penetration:
+ Sprecher and Hendrick (2004)
+ Sprecher et al (2013)
+ Has practical value, (Haas and Stafford (1998))
Sprecher and Hendrick (2004)
Studied heterosexual couples and found positive correlation between relationship satisfaction and self disclosure. Those who reciprocated self disclosure were more committed.
