RELATIONSHIPS Flashcards
(97 cards)
Define sexual selection
- Evolutionary explanation for partner preferences
- Attributes or behaviours that increase reproductive success are passed on and may become exaggerated over succeeding generations of offspring
Define anisogamy
- Difference between male and female+ female sex cells
What are the two mating strategies proposed by Charles Darwin?
- Intersexual selection
- Intrasexual selection
Outline intersexual selection
- Preferred mating strategy for females
- Members of one sex evolve preferences for desirable qualities in potential mates
- QUALITY OVER QUANTITY
(E.g. attractiveness + resources gain a mating advantage)
Outline intrasexual selection
- Preferred mating strategy for males
- Individuals of one sex competes with members of the same sex for members of the other sex
- QUANTITY OVER QUALITY
- successful individuals can mate + pass on their genes
Explain why mechanisms for mate choice evolve?
- Random mating is stupid mating
- Being ‘choosy’ (which is time + energy consuming) pays off as the genetic quality of a mate determines half the genetic quality of offspring
- Low-quality mates are likely to produce unattractive, unhealthy offspring
- FEMALES attracted to males who have resources + can invest resources in her and her offspring, can parent well + can protect them - for females creating offspring is TIME + ENERGY CONSUMING
- MALES - creating offspring requires little time, energy and responsibility
Outline a study supporting intersexual selection
- Fisher’s (1930) ‘sexy sons’ hypothesis
- If female chooses to mate w/ attractive male, her offspring will also grow up to be attractive so they will also attract mates
^— ensures female’s genes passed on
Define physical dimorphism
Differences in the body size and physical appearance between males and females
Outline the procedure of Buss (1989)
- Explored what males and females looked for in a long-term partner
- 10000 people from 37 different cultures
- Participants asked to rate each of 18 characteristics (e.g. physical attractiveness, good financial prospect) on how important they would be in choosing a mate
- Four-point scale used: 3 (indispensable) to 0 (irrelevant)
Outline the findings of Buss (1989)
RESOURCES - women desired mates who had good financial prospects more than men - desire for men with resources or ambition
PHYSICAL ATTRACTIVENESS - men placed more importance on physical attractiveness - cues a woman’s health + fertility
YOUTH - men universally wanted mates who were younger than them - indicated fertility
OTHER - both sexes wanted intelligent (linked to parenting skill) + kind (linked to interest in long-term relationships) mates
What are evolutionary explanations?
Focus on adaptive nature of behaviour
^— Modern behaviours are believed to have evolved because they solved challenges faced by our distant ancestors + became widespread in the gene pool
Briefly explain what is meant by the ‘matching hypothesis’
Claims that when people look for a partner for a romantic relationship, they tend to look for someone whose social desirability approximately equals their own
Walster and Walster (1969)
Outline the role of physical attractiveness in attraction
- Shackelford and Larsen (1997) - Symmetrical face more attractive = signs of genetic fitness
- NEOTONOUS features thought to trigger protective + caring instincts, related to formation of attachment
BOTH EVOLUTIONARY
What is the Halo effect?
- We hold preconceived ideas about the attributes of physically attractiveness people
^— believe all other attributes overwhelmingly positive
Pretty privilege
Outline the matching hypothesis as it applies to attraction
- Claims that, when initiating romantic relationships, individuals seek out partners whose social desirability approximately equals their own
- When choosing a partner, individuals first assess their own ‘value’ in the eyes of a potential romantic partner + select the best available candidates who would likely be attracted to them
- Both would theoretically be attracted to those most socially desirable, but partners similar to them in social desirability means increased likelihood of success
Describe the relationship between the matching hypothesis and physical attractiveness
- Matching hypothesis proposed ppl pair up with those with equal social desirability (a range of assets), though it has changed to only be associated with physical attractiveness
^— expect people to pair up with those similarly physically attractive - Walster et al: ‘realistic’ choices - each individual is influenced by the chances of their affection being reciprocated
Outline the procedure of one study of the matching hypothesis
- Walster et al (1966) advertised a ‘computer dance’ for new students at Uni of Minnesota
- 177 males + 170 females were randomly selected to take part
- When they came to pick up their tickets, 4 student accomplices surreptitiously rated each of them for physical attractiveness
- Participants then asked to complete long questionnaires (e.g. to assess personality, intelligence, etc) + told that the data would be used to allocate their ideal partner for the evening of the dance - PAIRING ACTUALLY RANDOM
- During intermission, participants asked to complete a questionnaire about their dates + a questionnaire 6 months after the dance
Outline the findings of one study of the matching hypothesis
- Walster et al. (1966)
- DID NOT SUPPORT MATCHING HYPOTHESIS
- Once participants had met their dates, they responded more positively to physically attractive dates regardless of their own physical attractiveness + were more likely to subsequently try to arrange dates with them if they were physically attractive
- Personality + intelligence did not affect liking the dates or any attempt to date them
What is self-disclosure?
When a person reveals intimate personal information about themselves to another person
What is social penetration theory?
- Altman & Taylor
- Suggests that as the relationship between individuals develops, interpersonal communications breadth + depth increase from shallow to more intimate
What is breadth in self-disclosure?
Types of topics
What is depth in self-disclosure?
Level of detail in topics
List THREE elements of self-disclosure
- Reciprocity
- Attributions
- Appropriateness
Explain reciprocity in self-disclosure
Relationships will only develop is both individuals are active in disclosing information + responding appropriately
