Social Influence Flashcards
What is conformity
A change in a person’s behaviour or opinions as a result of real or imagined pressure from a person or group of people
What are the three types of conformity and who made these labels
- Kelman (1958)
- Compliance
- Internalisation
- Identification
What is compliance
- private opinion does not change
- public opinion changes to agree with group
- superficial and temporary form of conformity
What is internalisation
- public views change to agree with group
- private opinion changes to match the public view
- deeper and more permanent conformity
What is identification
- moderate type of conformity
- identify with the group on a personal level (solidarity is formed)
- May agree publicly but disagree privately
- eg eating vegan food when with vegan friends even if you’re not vegan
What are the two reasons for conformity and who identified them
- informational social influence (ISI)
- normative social influence (NSI)
- Deutsch and Gerard (1955)
Define ISI
the person conforms because they are unsure of what is correct and do not want to stand out
What situations will ISI take place more often
- the situation is ambiguous
- the situation is more complex/difficult
- the situation is a crisis (rapid action)
- we think other people have more knowledge and know what to do
What form of conformity does ISI lead to
Internalisation
Define NSI
The person conforms in order to be liked and accepted by a group
In what situations is NSI more likely to occur
- when with strangers and there’s fear of rejection
* in stressful situations where people need social support
What form of conformity does NSI lead to
Compliance
What are the strengths for ISI
- Research support
* Lucas et al (2006) asked students maths Qs and saw conformity occur for harder Qs
What are the strengths for NSI
- Research support
* Asch (1951) found that PPs feared rejection and agreed to majority viewpoint
What are the weaknesses for ISI
• ISI does not affect everyone the same way
- Asch (1955) students Not conformist (28%) compared to PPs (37%)
- lacks population validity
- ISI AND NSI may be involved
- Asch. One other dissenting PP => conformity dropped
- Cannot tell if ISI or NSI dropped
• Lacks ecological validitiy
What are the weaknesses for NSI
• NSI does not affect everyone.
- nAffiliators have a greater need for affiliation (conform More)
- McGhee and Teevan (1967)
• lacks population validity
- ISI AND NSI may be involved
- Asch. One other dissenting PP => conformity dropped
- Cannot tell if ISI or NSI dropped
• Lacks ecological validity
Key studies for conformity
- Jenness (1932)
- Sherif (1936)
- Asch (1951)
Jenness aim
If individuals opinions change in ambiguous situations, after group discussion
Jenness method
- Glass bottle with 811 white beans
- 26 students estimate how many
- PPs groups of 3
- Guess again after
Jenness results
• Nearly all PPS change
- male by 256
- female by 382
• range went from 1875 to 474 (75% decrease)
Jenness conclusion
The opinions change because ISI
Sherif aim
Demonstrate people conform to group norms in ambiguous situations
Sherif Method part 1
• Autokinetic effect
• PPs were asked individually
-answers were given in large ranges (20-80cm)
• PPs were asked in groups of 3s. (Sherif manipulated the groups so 2 similar 1 diff)
Sherif results part 1
- Group converged to common estimate
* 1 pp diff conformed to 2 pp with similar answer
Sherif method part 2
- PPs were asked for their opinion in a group
* THEN asked again alone
Sherif results part 2
• Participants internalised the group norms
Sherif conclusion
People adopt group norms in ambiguous situations. ISI
Asch aim
Investigate the degree individuals conform to obviously wrong majority (non-ambiguous)
Asch method
- 123 America male students
- groups of 6-8
- one PP (others confederates)
- confederate gave same wrong answer
- 18 trials (12 critical)
• lab experiment (controlled)
Asch results
- 1/3 conformity rate (1/3 answers were wrong)
- at least 3/4 conformed in 18 trials
- 25% didn’t conform
Asch conclusion
Compliance + NSI
Variables affecting conformity
- Group size
- Unanimity
- Task difficulty
