Relationships Flashcards
According to evolutionary psychology:
- Partner preferences are driven by sexual selection
- This means that both males + females choose partners to maximise their chances of reproduction success
- Individuals with traits that maximise reproductive success (e.g. strength, height, aggression and wide hips etc) are more likely to survive + pass on genes responsible for their success
Anisogamy
- Males have gametes (sperm cells) which are able to reproduce quickly with little energy expenditure
- Female gametes (eggs or ova) are much less plentiful + require far more energy to produce
- This difference (anisogamy) means that males and females use distinct strategies to chose a partner
- Generally males use intra sexual selection + females use inter sexual selection
Intra sexual selection
- Is where members of one sex (usually male) compete with one another for access to the other sex
- This leads to male-female dimorphism which is accentuation of secondary sexual characteristics in those with greater reproductive fitness
- Anisogamy suggests that a male’s best evolutionary strategy is to have as many partners as possible
- Males must compete with other males to present themselves as the most attractive mate to fertile female partners
- Males might engage in mate guarding where they guard their female partner to prevent them mating with anyone else
- Males are fearful of having to raise another man’s child which is called cuckoldry
Inter sexual selection
- Is where members of 1 sex (usually female) choose from available prospective mates (usually males) according to attractiveness
- Anisogamy suggests that a women’s best evolutionary strategy is to be selective when choosing a partner
- Females will tend to seek a male who displays characteristics of physical health, high status and resources
- Thus the male partner is able to protect them + provide for their children
- Although this ability may have equated to muscular strength in our evolutionary past, in modern society it is more likely to relate to occupation, social class and wealth
Advantage of Evolutionary Explanations (1) - Buss study
- Buss (1989) conducted a survey of over 10000 adults in 33 countries + found that females reported valuing resource based characteristics (such as occupation)
- Whilst men valued good looks + preferred younger partners
- Cross cultural research is great evidence
Advantage of Evolutionary Explanations (2) - Clark study
- Clark and Hatfield (1989) conducted a now infamous study where male and female psychology students were asked to approach fellow students of Florida State Uni (of the opposite sex) + ask them for 1 of 3 things: to go on a date, to go back to their apartment, or to go to bed with them
- About 50% of both men + women agreed to go on the date
- 69% of men agreed to visit the apartment + 75% agreed to go to bed with them
- Only 6% of women agreed to go to the apartment + 0% accepted the more intimate offer
Disadvantage of Evolutionary Explanations (1) - deterministic
- The evolutionary approach is deterministic suggesting that we have little free will in partner choice
- However, everyday experience tells us that we do have some control over our partner preferences
Disadvantage of Evolutionary Explanations (2) - other relationships
Evolutionary theory makes little attempt to explain other types of relationships e.g. non-heterosexual relationships + cultural variations in relationships which exist across the world e.g. arranged marriages
Self Disclosure (SD)
- Several factors affect attraction in romantic relationships + one of these factors is self disclosure
- This is the revealing of personal info such as thoughts, feelings and experiences to another person
Altman and Taylor (1973)
- SD is a central concept in social penetration theory proposed by Altman and Taylor
- This theory claims that by gradually revealing emotions + experiences to their partner, couples gain a greater understanding of each other + display trust
- Therefore SD will increase attraction
Process of self disclosure
- As people build trust in their partner, the breadth and depth of SD will increase
- In the beginning people only disclose superficial details about themselves like hobbies and interests + gradually reveal more intimate details such as family values and difficult experiences
- Self disclosing too quickly e.g. on a first date can reduce attraction
Reciprocal self disclosure
- People expect the same level of SD from others as they actually give
- The more SD someone gives, the more SD they expect in return
- This known as reciprocal SD
Advantage of Self Disclosure (1) - Altman and Taylor
- Research conducted by Altman and Taylor supports the theory of SD
- They found that SD on the first date is inappropriate + didn’t increase attraction levels
- The person who was self disclosing was seen as maladjusted + not very likeable
Advantage of Self Disclosure (2) - cultures
- Kito (2010) found research evidence to support the idea of SD across diff cultures
- He investigated Japanese and American students in diff types of relationships + found that SD was high for Japanese and American students in romantic relationships that were heterosexual
Disadvantage of Self Disclosure (1) - given vs received
- Sprecher (2013) found research evidence that the level of SD received is the best predictor of liking and loving rather than the amount of SD given
- This goes against the idea of reciprocal SD
Disadvantage of Self Disclosure (2) - other factors
- It seems unlikely that attraction to a potential partner is based on SD alone
- SD might be an important element but other factors are also needed to increase attraction such as physical attraction, similarity of attitudes + complementarity of needs
Physical Attractiveness (PA)
- PA affects attraction in romantic relationships
- Men place a great deal of importance on PA when choosing a female partner in the SR + LR
- Research has shown that PA is also very important for females when choosing a male partner especially in the SR (less important in the LR)
- What is considered to be physically attractive varies across culture + time
Halo Effect (HE)
- The HE is when the general impression of a person is incorrectly formed from 1 characteristic alone (e.g. PA)
- Physically attractive people are often seen as more sociable, optimistic, successful + trustworthy
- People tend to behave positively towards people who are physically attractive + this creates a self fulfilling prophecy where the physically attractive person behaves even more positively because of the positive attention they receive
Advantage of the Halo Effect
- Palmer and Peterson (2012) found that physically attractive people were rated more politically knowledgeable than unattractive people
- The HE was so powerful that it persisted even when participants found that the physically attractive person has no expertise in politics
Disadvantage of the Halo Effect
- Towhey (1979) asked male and female participants to rate how much they liked an individual based on a photograph
- Paricipants also completed a MACHO scale which measures sexist attitudes + behaviours
- It was found that participants who scored highly on the MACHO scale were more influenced by PA
- Those who scored low on the questionnaire didn’t value PA
- Therefore, the influence of PA is moderated by other factors e.g. personality
The Matching Hypothesis (MH)
- When initiating romantic relationships, individuals seek partners that have the same social desirability as themselves
- PA becomes the major determining factor as it an accessible way for each person to rate the other person as a potential partner before forming a relationship
- Most people would prefer to form a relationship with someone who is physically attractive but in order to not be rejected many people will approach others who are of a similar attractiveness to themselves
Advantage of the Matching Hypothesis
- Fangold (1988) found supportive evidence for the MH by carrying out a meta analysis of 17 studies using real life couples
- He established a strong positive correlation between the partners’ ratings of PA just as predicted by the MH
Disadvantage of the Matching Hypothesis
- Sometimes a very physically attractive person forms a relationship with an unattractive person
- Often a rebalance of traits will occur where the less physically attractive person has some other traits to make up for the lack of PA e.g. being rich, having a high status or great personality
- This is called complex matching where a very attractive person forms a relationship with an unattractive person
Kerchoff and David (1962) proposed
- We use filtering to reduce the field of available partners to a field of desirable partners
- When we meet a potential partner we engage in 3 levels of filtering: social demography, similarity in attitude, and complementarity of needs
- We tend to be attracted to those who pass through a series of filters
