social influence Flashcards
What is conformity?
Change in person’s behaviour or opinions due to real or imagined pressure from others.
What are the 3 ways people may conform to majority?
Internalisation
Identification
Compliance
What is internalisation?
Accept group norms
Private + public change
Long-term (attitudes internalised)
What is identification?
Publicly change to fit in
Privately disagree
Value group but not all its beliefs
What is compliance?
Outwardly go along
Privately disagree
Stops when group pressure stops
What is normative social influence?
Conform to be liked or accepted
Emotional process
Leads to compliance
What is informational social influence?
Conform to be right
Cognitive process
Leads to internalisation
When does NSI occur?
With strangers (fear rejection)
With friends (social approval)
Stressful situations (social support)
When does ISI occur?
New/crisis situations
Ambiguous tasks
When someone is seen as expert
Strengths of conformity explanations
ISI: Lucas et al — more conformity when tasks hard
NSI: Asch — avoided rejection
Limitations of conformity explanations
NSI doesn’t affect all equally (e.g. affiliation)
ISI + NSI can occur together (dissenter = unclear which)
Asch’s conformity study – procedure
Line judgment task
123 male US undergraduates
Group with 6–8 confederates
Confederates gave wrong answers 12/18 trials
Asch – findings
Naive ppts conformed 36.8% of the time
25% didn’t conform at all
75% conformed at least once
Asch – variations
Group size
Unanimity
Task difficulty
Unanimity variation
One confederate disagreed
Conformity dropped by 25%
Ppt felt freer to dissent
Group size variation
With 3 confederates: 31.8% conformity
More confederates = no further rise
Task difficulty variation
Harder line tasks = more conformity
ISI increased
Strengths of Asch
Lab setting = controlled
Cause and effect established
Limitations of Asch
Perrin & Spencer (UK): only 1 conform in 396 trials
Temporal bias (1950s America)
Demand characteristics (knew they were in study)
Gender + culture bias
Conformity to social roles
Individual adopts behaviour in a social situation
Social roles
Expectations attached to positions (e.g. teacher, parent)
Zimbardo SPE – procedure
Mock prison at Stanford
Volunteers randomly assigned guard/prisoner
Arrested at home, uniforms issued
Guards had sunglasses, rules, uniforms
Zimbardo SPE – findings
Guards took roles seriously, became brutal
Prisoners rebelled, became passive
Study stopped after 6 days
Zimbardo SPE – conclusion
Power of the situation shapes behaviour
