Social influence Flashcards
Define conformity
A change in behaviour or belief as a result of real or imagined group pressure
Identity the 3 types of conformity
Compliance
Identification
Internalisation
Define compliance
Shallowest level of conformity
Individual changes behaviour to FIT IN with group/avoid rejection
Do not privately agree with behaviour/belief but do agree publically
Due to normative social influence (NSI)
Define identification
Individual adopts the behaviour/belief of group
Accept group’s norms out of desire for a relationship/association with the group
Define internalisation
Deepest level of conformity
Individual accepts behaviour/belief of majority publically AND privately - become part of their belief system
Due to informational social influence (ISI)
Identify the 2 explanations for conformity
Informational social influence (ISI)
Normative social influence (NSI)
Define NSI
Conforming to the majority to avoid rejection
Driven by desire to be liked
Leads to compliance
Define ISI
Conforming to majority because of a desire to the correct in situations where right action/belief is uncertain
Leads to internalisation
Who studied conformity?
What did he do?
What did he find?
Asch (1951) - line judgment study
Groups of 8-10 male college students
Only one actual ppt - all other were confederates
Ppts shown standard line + 3 comparison lines - ppts had to identify which line matched standard line
6 control trials - confederates gave correct answers
12 critical trails - confederates gave same incorrect answer unanimously
75% ppts conformed at least once
5% ppts conformed every time
Overall conformity rate in critical trials - 32%
Suggests people will conform due to NSI - conform for social approval, avoid rejection
Evaluate Asch’s study
KEY POINTS:
Ethical issues
Methological issues
Ethical issues:
- Deception + lack of informed consent
+ Debriefing was used to gain retrospective consent and ppts were informed of right to withdraw their results at that point
Methological issues:
- Poor external validity (low population validity, low ecological validity, low temporal valdity
- Low internal valdity - demand characteristics possibly present as ppts may have worked out what study was about
3 variables affecting conformity (Asch’s variations)
Group size - increasing size of majority (no. of conferderates) increased conformity (up to a point(
Unanimity - Asch arranged for a confederate to give different answer to majority and/or sam answer as real ppt. This reduced conformity
Task difficulty - Asch made real answer less obvious by having lines of similar length, increasing task difficulty increased conformity
Who investigated the power of social roles?
Zimbardo (1973) Stanford prison study
Procedure of Zimbardo’s study
24 U.S male student volunteers
Randomly allocated role of prisoner or guard
Prisoners:
- arrested from home, deloused, given uniform, ID number
- given some rights e.g. 3 meals a day, 3 supervised toilet trips a day, 2 visits a week
Guards:
- given uniform, clubs, whistles, wore reflective sunglasses
Zimbardo took role as prison superintendent
Findings of Zimbardo’s study
Experiment planned to last 2 weeks, but was stopped after 6 days
Many guards had become abusive
After rebellion was put down, prisoners became subdued, depressed and anxious
Conclusions of Zimbardo’s study
Situation had influenced people’s behaviour
Guards, prisoners + researchers all conformed to roles within prison
Evaluation of Zimbardo’s study
KEY WORDS:
3 ethical issues
3 methological issues
ethical issues:
- protection from harm + psychological harm
- right to withdraw (pressurised to stay)
HOWEVER - would have lacked realism if allowed to leave, therefore validity of a prison without this
- lack of informed consent (consent gained but unlikely sufficiently infomed)
methological issues:
- Zimbardo played ‘dual role’ - became to involved - his behaviour may have influnced way in which event unfolded
- criticized for likely demand characteristics
- reasonably poor ecological validity - not a real prison - difficult to generalise
Who investigated obedience?
Milgram’s (1963) electric shock study
Sample of Milgram’s study
40 male ppts
Aged between 20-50
All American - New Haven area
White, middle class
Volunteers
Procedure of Milgram’s study
Drew starts to assign role of leaner + teacher - it was rigged, ppt always teacher, confederate always learner
Ppts told that confederate/leaner had heart condition
Shocks on scale of 15V - 450V in 15V increments
Learner gave mainly wrong answers on purpose
If ppt refused to administer shock - series of prods used by experimenter
Teacher + learner in separate rooms
NO SHOCK ACTUALLY ADMINISTERED - ALL FAKE
