Social influence

Conformity:

Asch’s study on conformity - lab experiment - NAMED STUDY

Aim: to investigate group pressure in an unambiguous situation

Method:

  • participants were asked to identify which line was closest in length to a target line

  • confederates gave the wrong answer

  • 123 American men

  • 12 critical trials

Results:

  • participants gave the wrong answer 1/3 of the time

  • 25% never gave the wrong answer

Conclusion:

  • people are influenced by group pressure

  • some can resist

Evaluation:

Weakness - only reflective of 1950s America - much less conformity in 1980s UK study - can’t be generalised everywhere

Weakness - trivial task - artificial task and situation involved strangers - not representative of everyday life

Weakness - doesn’t apply to all cultures - results are not the same in individualist and collectivist cultures and study only contained a limited sample of participants - can’t be generalised to different cultures

Social factors affecting conformity: (situational factors)

  • Group size: conformity increases from 2 to 3 confederates - more than 3 makes no difference

    Evaluation: depends on task - when answer is not obvious/ambigous, no conformity until group is 8+ people

  • Anonymity: if answer is anonymously given conformity decreases

    Evaluation: if participants are friends, conformity is higher

  • Task difficulty: more difficult task = more conformity (if comparison lines are more similar to target line, conformity increases)

    Evaluation: experts less affected by task difficulty

Dispositional factors affecting conformity: (personal factors)

Personality: high internal locus of control = less conformity (people more likely to go with their own opinion)

Evaluation: less important in familiar situations

Expertise: people with specific knowledge or skills conform less

Evaluation: experts sometimes conform in order to be liked (eg. maths experts may conform even if they know the answer is wrong in order to be liked)

Obedience:

Milgram’s study on obedience

Aim: to investigate if Germans in WW2 were different in terms of obedience

Method:

  • teacher (participant) instructed to give electric shock to learner if they got a question wrong

Results:

  • extreme tension - 3 had seizures

  • no one stopped below 300 volts

  • more than half (65%) went up to maximum (450 volts)

Conclusion: obedience related to social factors (not disposition)

Evaluation: (don’t need to know in detail)

  • ethical issues

  • supported by other research

  • participants may not have believed shocks were real

Social factors that affect obedience: Milgram’s agency theory

Milgram’s agency theory - In the presence of someone who is perceived as being in authority, people experience an agentic shift from an autonomous state to an agentic state.

agentic shift - autonomous state → agentic state

autonomous state - own free choice

agentic state - follow orders with no responsibility (under the influence of authority)

cultural influence - we are socialised into believing that some people have more authority than others, depending on society and socialisation

proximity - participants in Milgram’s study were less obedient when in the same room as the learner, increasing moral strain

Evaluation:

weakness - doesn’t explain all of the findings - can’t explain why there wasn’t 100% obedience in Milgram’s study - dispositional factors must also play a role

strength - supported by research - people blamed the experimenter rather than the participants in Milgram’s study

weakness - offers an excuse for dangerous behaviour - can be used to excuse the behaviour of Germans under the Nazis

Dispositional factors that affect obedience: Adorno’s theory of the authoritarian personality

  • strong respect for authority and look down on people of lower social status

  • rigid cognitive style

  • do not like change

  • originates in childhood from strict parenting and conditional love

  • displaced anger at parents onto people who they see as socially inferior

Evaluation:

weakness - measured using the F scale - response bias -decreases validity

weakness - results are only correlational - does not mean causation - authoritarian personality may not cause obedience

weakness - social factors also apply - Germans were obedient in WW2 but did not all have the same upbringing - decreases validity

Prosocial behaviour:

Piliavin’s subway study on prosocial behaviour - field experiment - NAMED STUDY

Aim: to investigate bystander behaviour - whether characteristics of a victim affect whether or not help is given

Method:

  • 103 trials

  • male confederate collapsed on a subway in new york

  • victim appeared either drunk or disabled (with a cane)

  • another confederate acted as a ‘model’ if no one else helped

Results: disabled victim given help 95% of the time, drunk victim given help 50% of the time. Help was equally likely in crowded and empty carriages.

Conclusion: characteristics of the victim do affect whether help is given. Not affected by number of onlookers.

Evaluation:

strength - took place in a natural setting - participants didn’t know they were being studied so more likely to act naturally - high realism

weakness - limited sample - all participants were from the city so may have been more used to emergencies - not generalisable

strength - produced quantitative data - observers noted remarks made by passengers - gives deeper insight

Social factors affecting prosocial behaviour:

  • Presence of others: the more people there are, the less likely someone will help

    Evaluation: depends on situation - in serious situations likelihood of help correlated to severity of emergency

  • Cost of helping: the higher the cost of helping, the less likely people will help

    (eg. danger to self/embarrassment, also cost of not helping, eg. guilt/blame)

    Evaluation: interpretation of situation differs - eg. people less likely to intervene when a married couple was arguing than when they appeared to be strangers

Dispositional factors affecting prosocial behaviour:

  • Similarity to victim: help more likely if the victim is similar to self

    Evaluation: help not always dependent on similarity (eg. in ambiguous/high cost situations)

  • Expertise: experts more likely to help (eg. nurse in a medical emergency)

    Evaluation: may only affect quality of help given (not always shown to affect likelihood, eg. red cross trained people just as likely to help but gave better quality help when they did)

Crowd and collective behaviour:

Reicher’s case study: St Paul’s riot

Aim: to see if crowd behaviour is ruly or unruly

Method:

  • studied TV/news reports about the riot

  • interviewed 20 people

Results:

  • riots triggered by police raiding cafe which community felt was unjust

  • crowd threw bricks and burnt police cars

  • calmed when police left

Conclusion: damage was rule driven and targeted at police, reflecting the attitude of the area

Evaluation: (don’t need to know in detail)

  • may be biased as based on eyewitness testimonies

Social factors that affect crowd and collective behaviour:

  • Deindividuation: group norms determine crowd behaviour - people lose their individual identity

    Evaluation: crowding may also influence behaviour - unpleasant experience - may explain antisocial behaviour

  • Social loafing: people put in less effort when working in a group because you can’t identify individual effort

    Evaluation: depends on the task - people put in more effort when brainstorming in groups

  • Culture: collectivist cultures put in the same amount of effort whether in groups or not (eg. China) - not true of individualist cultures (eg. USA)

    Evaluation: overgeneralised - some people belong to more than one culture - hard to make predictions

Dispositional factors that affect crowd and collective behaviour:

  • Personality: people with a high locus of control are less influenced by group behaviour

    Evaluation: makes no difference when whistleblowing

  • Morality: strong sense of right and wrong (morals) helps to resist group pressure

    Evaluation: backed up by real examples - eg. Sophie Scholl not following Nazis

Zimbardo’s study on deindividuation: (anonymous electric shock study)

Aim: to study the effects of deindividuation

Method:

  • female participants told to deliver fake electric shocks

  • individuated group wore normal clothes

  • deindividuated group wore coat & hood

Results: deindividuated participants more likely to shock and held the shock button down twice as long

Conclusion: anonymity increases aggression

Evaluation: (don’t need to know in detail)

  • real world application - managing sports crowds with TV screens

  • prosocial group norm (eg. nurses) encourages prosocial behaviour - does not always lead to antisocial behaviour, depending on group
