1 Social Influence Flashcards
(47 cards)
Variables investigates by Asch: Group size
Varied confederates to 1 to 15 (so group size was 2 to 16).
Asch found a curvlinear relationship between group size and conformity rate. Conformity increased with group size up to a point
* 3 confederates conformity=31.8%
But more confederates=little difference
So, most people are sensitive to views of others 1 or 2 confedereates is enough to sway opinion
Variables investigated by Asch: Unanimity
A confederate who disagreed with the other confederates was added. Sometimes they said the wrong answer, sometimes they said the right answer
* Conformity rate of naiive particpant = less with dissenter present even if they said an incorrect answer
* Rate decreased to less than a quarter of the level when unanimous
Variables investigated by Asch: Task difficulty
Increased difficulty of task by making lines (stimulus + comparison) more similar in length
* Conformity increased with difficulty
* This could be due to it being ambiguous
* Informational social influence may occur (assume others are right when faced with a challenging task)
Asch’s baseline study
Aims- measure the extent to which people conformed to others opinions, even when clearly wrong
Procedure
123 American men as participants. 2 cards were presented to participants, one had a standard line and the other had 3 comparison lines. The participants were asked to state which line (A, B or C) matched the standard line. There was one clear answer and the others were obviously wrong. The participant was in a group with confederates (but the naiive participant thought they were real participants). The confederates were all told to give the incorrect answer. The groups were of 6 to 8 people and the naiive participant always went last or second to last.
Results:
The genuine participants agreed with the confedereates 36.8% of the time. But, there were individual differences as 25% of participants never gave a correct answer.
Asch’s investigation: Limitations
Artificial task + materials
* Identifying lines=trivial, so no reason to not conform. Also didn’t reflect real-world tasks
* Groups weren’t very ‘groupy’- did not resemble real-life groups
* Do not generalise to real-life situations
Limited application to other cultures
* Only used American men
* Research- Women may be more conformist (more concerned about social acceptance)
* Research- collectivist cultures have higher conformity rates
Ethical Issues
* Naiive pps = decieved (thought other pps were real not confederated)
* Only mild deception, increased knowledge on conformity. Ethical cost vs benefits
Asch’s investigation: Strengths
Research support about task difficulty
* Tod Lucas et al= pps solve easy + hard maths. Pps given 3 other (fake) student answers.
* Pps conformed more when task = hard (like in Asch)
Counterpoint
* Tod Lucas et al = pps w/ high maths confidence = less conformity on hard tasks than low confidence
* Individual factors influence conformity by interacting with situational variables (task difficulty)
Types of conformity: Explain what is meant by internalisation
- Where behaviour or belief of the majority is accepted by the individual becoming part of their belief system.
- Most permenant, lasts even if majority not present
- Likely linked to ISI
Types of conformity: Explain what is meant by compliance
- Where an indiviual changes their behaviour to fit in with the group
- May not agree with belief/behaviour but they go along with it in public
- Not permenant, lasts only if the group is present
- Most likely linked to NSI
Types of conformity: Explain what is meant by identification
- Where an indiviual changes their behaviour/beliefs to match with the group because there is something in that group they value
- They identify with the group so want to be part of it
- Changes public behaviour private beliefs only in the presence of the group they are identifying with
- Short-term change, moderate conformity
Explanations of conformity: Explain what is meant by normative social influence (NSI)
- When a person ‘goes along’ with the beahviour/belief of the group to gain social approval and to be liked
- This may lead to compliance
Explanations of conformity: Explain what is meant by informational social influence (ISI)
- When an individual agrees with the beliefs of the majority because they believe it to be correct
- They accept it because they want to be correct as well
- This may lead to internalisation
Explanations of conformity
When are the following most likely to occur
* ISI
* NSI
ISI
* New situations –> not sure what is right
* Ambiguous situations –> not clear what is right
* Crisis situations –> assume group is right due to time pressure
NSI
* Strangers –> concerned about rejection
* Friends –> concerned about social approval
* Stressful situations –> greate need for social support
Explanations for conformity- Strengths
Research support for NSI
* Asch found pps conformed because they are afraid of disapproval
* When pps wrote answers (no normative pressure) conformity = 12.5%
* Some conformity is due to desire to not be rejected by group for disagreeing
Research support for ISI
* Lucas Et al found pps conformed more to incorrect answers if maths problems were harder. (With easy problems they ‘knew their own mind’)
* Hard problems=ambiguous –> relied on others answers
* Supports ISI as results are what ISI would predict
Counterpoint
* Unclear if it is NSI or ISI in studies
* Asch- when a dissenter was present it may be ISI or NSI that is reduced
* NSI provides social support but ISI provides an alternative source
* So, had to seperate and operate in real world scenarios
Explanations for conformity- Limitations
Individual differences in NSI
* Some are concerned about being liked by others- nAffiliators have a strong need for affiliation (need to relate to others)
* McGhee and Teevan found nAffiliator students = more likely to conform
* So, NSI underlies conformity more for some than others- individual differences not explained by theory of situational pressures
Is NSI/ISI distinction useful?
* Lucas et/al found NSI/ISI distinction may not be useful as it is impossible to work out which is operating
* But Asch’s research supports NSI and ISI as explanations (group unaminity: avoid rejects + majority more likely to be right)
* Both are useful to identify + explain real life conformity
Conformity to social roles as investigated by Zimbardo AO1
Zimbardo (1973) The Stanford Prison Experiment
Aims- Effect of social roles on conformity
Procedure-
1. 21 male student volunteers- selected by psychological testing showing them to be ‘emotionally stable’
2. Randomly allocated to role of guard or prisoner.
3. Social roles encouraged by uniform- Prisoners were strip searched, given uniform + number. Guards had own uniform with handcuffs + sunglasses
4. Social roles encouraged by instructions- prisoners were told they couldn’t leave but could ask for parole. Guards told they had complete power
Results
1. Guards treated prisoners harshly and so prisoners rebelled withing 2 days
2. Eg, guards harassed prisoners and retaliated with fire extinguishes
3. Guards threatened prisoner’s psych + phys health
4. 1. Eg after rebellion prisoners = subdued, anxious + depressed. 2. Eg 3 prisoners released early. 3. Eg, prisoner went on hunger strike + guards tried to force feed him + put him in the hole
Conclusions- Social roles are powerful influences on behaviour- most conformed strongly
Guards became brutal, prisoners became submissive.
Generalised to Nazi’s as they were following orders
Conformity to social roles as investigated by Zimbardo- Strengths
Balancing Roles: Random Assignment Mitigates Personality Influence
* Emotionally-stable pps were recruited (through assessment of mental stability)
* Pps randomly assigned roles
* Pps only had roles by chance so behaviour was due to role, not their personality/suitability to role
* Increased internal validity
* Higher confidence in drawing conclusions
Conformity to social roles as investigated by Zimbardo- Limitations
Were the characters just based on stereotypes or were the lines between fiction and reality trule blurred?
* Research= play acting their roles. Reflected stereotypes found in media
* One guard based role on a character from Cool Hand Luke
* Prisoners rioted as they thought they were supposed to
* Tell us little about conformity to social roles in prisons.
* Counterpoint
* Research= pps behaved as if it was real
* eg, 90% of convo= prison life. Prisoner 416 thought it was a prison ran by psychologists
* Replicated role of guard + prisoner in real prison, increasing internal validity
All an exaggeration- only 1/3 were actually brutal!
* Power of social roles to influence behaviour may have been exaggerated
* Only 1/3 of guards behaved brutally
* Another 1/3 applied rules fairly
* Final 1/3 supported prisoners, offering cigarettes and reinstating priveleges
* SPE overstates the view that the guards were conforming to a brutal role
* Minimised dispositional factors eg personality
Why did some resist the pull of the role? The situational identity theory has answers
* Zimbardo claim = pps naturally took on their social roles- just having a role meant that pps conformed to expectations associated with it
* Doesn’t explain non-brutal guards
* Social identity theory argues only those who identify with role of guard conform
* So, posssible to resist situational pressures to conform to sovial role –> if not identifying with role
Obedience as investigated by Milgram- procedure
Procedure
* 40 American male pps for a study of “memory”
* Drew rigged lots for role
* A confederate = learner, true pp = teacher, a confederate = experimenter
* Experimenter wore lab coat
* Teacher could hear learner not see them
* Teacher gave learner electric shochs each time he made a mistake, these increased in intensity
* Max vols = 450
* Experimenter gave verbal prods to continue if teacher expressed wish to stop
Obedience as investigated by Milgram- findings + conclusions
Key findings
* 12.5% (5pps) stopped at 300 volts
* 65% continued to 450 volts
* Observations = pps had extreme tension. 3 has ‘full-blown uncontrollable seizures’
Other findings
* 14 psych students predicted results + estimated no more than 3% would continue to 450
* So, baseline results = unexpected
* Pps debriefed + follow up questionnaire = 84% glad of participating
Conclusion
* We obey legitimate authority even if that means that our behaviour causes harm to somebody else
Obedience as investigated by Milgram- Strengths
French TV Game Show Mirrors Milgram’s
* French game show = contestants paid to give (fake) electric shocks, ordered by the presenter, to other pps (actors).
* 80% of contestants gave maximum 460 volts to a seemingly unconscious man.
* pps had many signs of anxiety- similar to Milgram’s experiment
* Increased validity + reliability
Obedience as investigated by Milgram- Weaknesses
Obedience or theatre?
* Researchers= pps guessed electric shocks were fake –> play acting
* Other research= Only 1/2 pps believed shocks were real due to voicing their suscpicions
* Pps responded to demand characteristics –> reduced validity
* Counterpoint
* Sheradin and King= pps gave real shock to a puppy
* 54% males + 100% females gave what they thought= fatal shock
* So, obedience in Milgram’s might be genuine
* But, not generaliseable to women who may have higher obedience
Social identity theory destroys idea of blind obedience
* Researcher= every pp given first 3 pods obeyed experimenter but if given fourth prod they disobeyed
* Social identity theory- first three pods required identification with the science of the research but fourth required blind obedience
* Findings best explained in terms of identification w/ scientific aims + not blind obedience to authority
* Reducing ecological validity of the experiment to have its findings applied to Nazi Germany.
Were the ethical issues managed appropriately?
* Pps = decieved
* Eg, thought shocks = real
* Researcher objection= deception could have led to serious consequences for pps
* Eg, no informed consent
* Eg, no protection from harm (3 had seizures + many extreme anxiety)
* So, research can damage reputations of psychologists and their research in public eye
* Counterpoint
* Milgram debriefed pps
* Follow up questionnaire= 84% glad they participated
* So, not too damaging
Obedience- Situational variables: Proximity
Proximity
* Baseline- teacher could see learner but not hear them
* Variation- Teacher + learner = same room
* Findings- obedience rate dropped from 65% to 40%
* Touch proximity variation- teacher forced hand onto electric shock plate
* Findings- obedience dropped a furth 30%
* Remote instruction variation- experimenter gave instruction via telephone
* Findings- obedience decreased tp 20.5%
Explanation
* Decreased proximity –> psychological distance themselves from consequences of actions
* Eg in baseline- teacher + learner seperate –> teacher can distance from harm
* Decreased proximity –> increased obedience
Obedience- Situational variables: Location
Location
* Variation- run down office instead of prestigous yale uni building
* Findings- obedience fell to 47.5%
Explanation
* Prestigour environment gave study legitimacy + authority
* More obedient –> experimenter had legitimacy
* Obedience still high in office as they percieved it was scientific
Obedience- Situational variables: Uniform
Uniform
* Baseline- experimenter –> grey lab coat –> authority symbol
* Variation- experimenter ‘called away by phone call’ –> ordinary member of public (confederate) in normal clothes took over
* Findings- obedience rate dropped to 20%
Explanation
* Uniforms encourage obedience –> recognised symbol of authority
* Someone in uniform = legitmate –> entitled to expect obedience
* Without uniform = no entitlement
