Social influence Flashcards
Aschs Procedure
Asses what extent people will conform to other people’s opinions
123 American men, match the correct line to line x, one was clearly the same length. Testing in groups of 6-8, only 1 was genuine participant, always seated last two, the rest were confederates had to give the same incorrect answer
Aschs finding
Agreed with incorrect answers 36.8% of the time
25% never gave a wrong answer
Variable investigated by asch
Group size
Unanimity
Task difficulty
Group size
Varied confederates from 1-15. Conformity increased with group size up to a point. 3 confederates conformity was 31.8% more confederates made little difference
Unanimity
presence of non-conforming present. Conformity decreased less than 1/4 of the level when it was anonymous
Task difficulty
Lines closer together, conformity increased, informative social influence
Evaluation of aschs
- Artificial situation and task
- Limited application
- research support
artificial situation and task
- participants knew they were in study- demand characteristics
- fiske- groups dont resemble groups in real life
- findings dont relate to real life
limited application
- all participants american men
- US individualist culture (more concerned about themself)
- similar studies done in collectivist culture (social group more important)found conformity rates higher
research support
- todd lucas - asked participants to solve easy to hard maths problems
- conformity rates higher for harder questions
research support counterpoint
- study found conformity more complex than asch
- participants with high confidence in maths conformed less
- shows an individual-level factor can influence conformity by interacting with situational variables
Asch ethical issues
Participants were deceived,
Types of conformity
Internalisation
Identification
Compliance
Internalisation
Person genuinely accepts groups norms, private and public change of opinion
Identification
Publicly change opinions to be accepted by a group
Compliance
Going alone with others in public but privately not changing personal opinions
Only superficial change
Informational influence
Follow behaviour of the group because they want to be right
Cognitive process
Informative influence strength
Todd Lucas found participant conformed when questions were harder, they didn’t want to be wrong so relied on answers they were given.
informative influence weakness
- Unclear where NSI and ISI work in research studies or real life
- Asch found conformity reduced when there is one other dissenting participant, may reduce the power of ISI or NSI
- Hard to separate ISI and NSI and both operate together in real world situations
Normative social influence
Gain social approval rather than be rejected, temporary change in options/ behaviour
Emotional process
Normative social influence strength
- Aschs interview states some said they conformed because they felt self-conscious, and afraid of disapproval
- when answers written down conformity dropped 12.5% - no normative group pressure
normative social influence weakness
- Doesn’t predict conformity in every case
- McGhee and Teevan – found students who were nAffiliators were more likely to conform
- NSI underlines conformity for some people more than it does for others
Zimbardo procedure
- mock prison experiment in Stanford uni
- 21 men emotionally stable, randomly assigned either guard or prisoner
- Prisoners encouraged to conform to social roles
- Uniforms - Prisoners identified as numbers, creates loss of personal identity (de-individualisation)
Zimbardos findings
- Within 2 days prisoners rebelled, guards harassed prisoners
- 1 prisoner was released for symptoms of physchological disturbance
- 2 more released on 4th day.
- Guards behaviour became increasingly brutal and aggressive some enjoying the power
- Study ended on day 6 instead of 14
Zimbardos conclusion
Social roles have strong influence over behaviour
Zimbardos evaluation
Control
Lack of realism
Exaggerates the power of role
Control
-selection of participants (choosing emotionally stable) ruled out individual personality differences
- randomly assigned a role
- increased internal validity
Lack of realism
- Not like a real prison
- Banuazizi and Movahedi (1975) argued participants were play-acting and confirming to a role
- Performance was based on stereotypes
- one guard said perfomance based on film cool hand luke
lack of realism counterpoint
- McDermott argues participants behaved as itwas to real to them
- 90% of prisoners convos were ab prison life
- 1 prisoner believed prison was real but run by psychologists
- study replicated the social roles of prisoners and guards in real prison, giving study high internal validity
Exaggerates the power of roles
- Only 1/3 of guards actually behaved in a brutal manner
- 1/3 tried to apply rules fairly. - rest sympathies with the prisoners
- most guards able to resist situational pressure to conform
- zimbardo overstated his view
Milgram procedure
- 40 American men aged 20-50
- Learner was trapped in a chair and wired up who had to remember pairs of words
- Each time he made an error the teacher had to deliver a shock getting stronger each time
- when reach 300v learner banged on the wall, 315v was silent
- All shocks were fake
Milgrams findings
- Every participants delivered the shock up to 300
- 12.5% stopped at 300
- 65% continued to highest level (450)
- Participants were seen to sweat, 3 had seizures
- Predicted only 3% would continue to 450 showing results were unexpected
Milgrams conclusion
German people are not different, participants were willing to obey orders even when it may harm others
Milgrams evaluations
Research support
Low internal validity
Alternative interpretation of findings
Research support
- Replicated in french documentary
- participants were paid to give fake electric shocks to other participants
- 80% reached top 460v almost identical to milgrams behaviour
Low internal validity
- Orne and Holland argued participants believed it was fake so play acted
- Perry listened to tapes of participants around 1/2 believe shocks were real
- 2/3 of them were disobedient
- participants may be responding to demand characteristics
low internal validity counterpoint
- sheridan and King study like Milgram
- participant gave real shock to puppy in response to orders from experimenter
- 54%men 100% women gave fatal shock
- Milgram was genuine similar results when shocks were real
Alternative interpretation of findings
- Haslam showed obeyed when experimenter gave verbal prods
- According to social identity theory participants only obeyed when they identified with the scientific aims of the research
