Social influence Flashcards
Paper 1
What variables did Asch study in his baseline procedure
- Group size
- Unanymity
- Task difficulty
3 weaknesses for Aschs study
- Task and situation artificial - participants may have displayed demand characteristics
- Participants only consisted of American men - collectivist culture + women may be more comformist
- Lucas et al discovered conformity is more complex - individual level factor could influence conformity
One strength of Aschs study
- Support from other studies for the effects of task difficulty : Lucas et al - maths questions ranging in difficulty - people conform more when maths question was harder
Name the three types of conformity
- Internalisation
- Identification
- Compliance
Who suggested those three types of conformity
Herbert Kelman
What are the two explanations for conformity and what do they each mean
- Informational social influence : Conforming based on who has better information :cognitive process
- Normative social influence : Conforming based on what is normal for a social group : emotional process
Which psychologists suggested these explanations for conformity (ISI and NSI) and what is the theory called
Deutsch and Gerard - Two - process theory
One strength and one weakness for the Normative social influence
Strength - Evidence supports this as an explanation for conformity : Asch - some participants conformed as they felt self-conscious giving correct answer and afraid of disapproval
Weakness - It does not predict conformity in every case - NSI underlies conformity for some people more than it does others - individual differences
One strength and weakness of Informational social influence
Strength - Research evidence to support ISI from Lucas et al - When maths problems were easier participants ‘knew there own minds’ but when problems were harder the situation became more ambiguous - participants did not want to be wrong so relied on the answers
Weakness - Difficult to decipher between ISI or NSI in studies - both processes probably operate together
What did Zimbardo do (procedure) and what was he studying (aim)
Aim : Look at how and if people comform to social roles
Procedure:
- Took place in Stanford University - psychology base created into mock prison
- 21 male student volunteers who tested as ‘emotionally stable’
- Participants randomly assigned prison guard or prisoner
- Participants given uniforms relevant to roles stripping them of their identity (deindividuation)
- Prisoners and guards were persuaded and pushed to behave like role (e,g guards continually told they had power over prisoners and prisoners could ‘apply for parole’)
Findings of Zimbardos research
- Guards took up roles with enthuisiasm treating prisoners harshly
- Within 2 days prisoners rebelled
- After rebellion was put down prisoners became subdued, depressed and anxious
- 1 was released due to psychological disturbance
- 2 more released on the 4th day
- 1 prisoner went on hunger strike
- Guards behaviour became increasingly more aggressive and brutal
- Zimbardo ended the study early - intended length : 14 days , actual length : 6 days
2 strengths of Zimbardos experiment
- Zimbardo and colleagues had control over key variables : degree of control increases internal validity - more confident about drawing conclusions about influence of roles on conformity
- Participants did behave as though prison was real to them ( McDermott) - 90% of conversations between prisoners was about prison life
2 weaknesses of Zimbardos experiment
- Experiment did not have the realism of a true prison (lacks realism) - participants merely play acting and performances based on stereotypes (influence of media)
- Zimbardo may have exaggerated the power of social roles to influence behaviour - only 1/3 of guards behaved in brutal manner another third applied to rules fairly and the rest sympathised with prisoners
What did Milgram do (procedure) and what was the aim
Aim : Assess obedience levels
Procedure :
- 40 American men - volunteers
- Drew lots to see who would be the ‘teacher’ and who would be the ‘learner’ - draw was fixed so participant would always be teacher and the confederate and confederate would always be learner
- Experimenter dressed in grey lab coat
- Learner strapped into chair and wired up with electrodes
- Each time the learner made a mistake the teacher was ordered to give increasinglt worse (fake) electric shocks
What were the findings of Milgrams research
- 100% participants - gave up to 300 volts
12.5% (5) - stopped at 300 volts - 65% - continued to highest level of 450 volts
- collected qualitative data : participants showed signs of anxiety and tension (sweating , dig fingernails into hands and stutter)
- 3 participants had full blown seizures
2 strengths of Milgrams study
- Findings replicated in a French documentary that was made about reality TV - findings replicable
- Sheridan and King conducted a study using similar procedure : Participants gave real shocks to puppy - 54 % of men and 100% women gave what they thought was a fatal shock
2 weaknesses of Milgrams study
- Orne and Holland argued that participants behaved as they did because they didn’t believe in the set up so were ‘play acting’ - demand characteristics
- Conclusions about blind obedience may not be justified - Social identity theory : participants only obeyed when they identified with scientific aims of the study ; when ordered to blindly obey an authority figure they refused
What 3 situational variables are there for Milgrams experiment
- Location
- Uniform
- Proximity
How did they study the effect of these variables and what did there results show : (Milgram)
Proximity :
Original : teacher could hear the learner but not see them
Variation : teacher and learner in the same room - obedience dropped from 65% to 45%
Decreased proximity allowed people to psychologically distance themselves from the consequences
Location :
- Original study : Yale
Variation : run down office building
- Obedience fell to 47.5%
- Prestigious university gave experiment legitimacy and authority
Uniform :
- Original : grey lab coat
Variation : experimenter called away and replaced with ‘normal member of the public’ - obedience dropped 20%
Uniforms are widely recognised symbols of authority - legitimacy of authority
2 strengths and 2 weaknesses of the situational variables of Milgrams research
Strength - other studies have demonstrated the influence of situational variables on obedience : Bickman tested Uniform (Milkman, security guard and jacket and tie) - people 2x as likely to obey person dressed up as security guard
Strength - Findings have been replicated in other cultures : Meeus and Raaijmaakers - Dutch experiment - Interview situation : Milgrams findings valid across cultures and women
Weakness - Replications not very cross-cultural : Countries such as Jordan and India different culturally to America, Australia etc - not appropriate to conclude that it is applicable to all cultures
Weakness - Participants may be aware that the experiment was faked : Holland and Orne
