Social influence Flashcards
what is conformity?
a change in a persons behavior or opinions as a result of a real or imagined pressure from a person or a group.
who suggested that there are three ways that people conform?
Herbert Kelman (1958)
what is internalisation?
when a person genuinely accepts a new belief. changing their public and private thoughts and behaviors. this change is a permanent one that persists even when the initial influence is gone.
what is identification?
when a person changes their public and private views and behaviour in order to fit into a new group. this change is not permanent.
what is compliance?
when a person simply goes along with a group. changing their public opinion but not their private opinion. it is superficial and very temporary.
who put forward the ‘Two Process Theory’?
Morton Deutsch and Harold Gerard. (1955)
what is Informational social influence?
an explanation of conformity that sees people conform because they believe that the majority is correct. ISI is about wanting to be correct. may lead to internalisation.
what is Normative social influence?
an explanation of conformity that sees people conform due to a need to fit in and be accepted by a group. NSI is about wanting to be liked. may lead to compliance.
evaluate the two process theory.
- Research support for ISI: Lucas et al. asked students to give answers to easy and hard mathematical problems. conformity was higher for harder questions. especially in students who rated their ability as poor.
- individual differences in NSI: some people have more of a desire to fit in and be liked - nAffiliators. Mcghee and Tavern found people with a high need for affiliation conformed more than others.
- Both processes are often involved: when conformity is reduced to a dissenting ppt. in Asch’s study it reduces both ISI and NSI. in real life the lines are even more blurred.
- Asch can basically be used for all evaluation.
describe Asch’s procedure.
- showed participants two cards, one standard line and three comparison lines
- tested 123 male undergraduates
- each participant was placed in a group of between 6 and 8 confederates.
- confederates began to give wrong answers.
- 18 trials overall, in 12 critical trials the confederates gave the same wrong answer.
describe Asch’s findings.
participant gave the wrong answer 36.8% of the time. 25% of participants did not conform on any trial. 75% conformed at least once. when interviewed afterwards participants said they conformed to avoid rejection (NSI)
describe the procedure and finding of Asch’s group size variation.
with three confederates conformity rose to 31.8% but any further addition of confederates made little difference.
describe the procedure and finding of Asch’s unanimity variation.
Asch introduced a confederate who sometimes gave the right answer (different to the other confederates) conformity was reduced to 5.5%
describe the procedure and finding of Asch’s task difficulty variation.
Asch made the length of the comparison lines more similar to the original line to increase the difficulty of the task. conformity increased suggesting that conformity was down to ISI when the task became more difficult.
Evaluate Asch.
- Temporal validity: Perrin and Spencer repeated the study with engineering students in the UK. just one student conformed in 396 trials. possibly because 1950’s America was a much more conformist society.
- Artificial situation and task: the task was very trivial so demand characteristics may have encouraged ppts. to conform anyway. the groups Asch used also don’t have a high ecological validity.
- limited application of findings: Asch only tested men, no women. America is an individualist culture, studies done in collectivist cultures like China imply higher levels of conformity
describe the procedure of the Stanford Prison Experiment.
- Zimbardo set up a mock prison in the basement of Stanford University
- He advertised for students willing to volunteer and selected those deemed emotionally stable.
- the students were randomly assigned the role of guard or prisoner
- prisoners were arrested in their homes, strip searched, deloused and given a uniform and number.
- guards worked on shifts, three at a time, enforcing 16 strict rules and only addressing prisoners by number.
- guards were given their own uniform, sunglasses and wooden club.
describe the findings of the Stanford Prison Experiment.
- the study was stopped after just 6 of the intended 14 days.
- within two days the prisoners rebelled against the guards, shouting and ripping their clothes. the guards responded with fire extinguishers.
- the guards tried to divide the prisoners, reminding them of who was in charge and constantly harassing them.
- the guards conducted frequent headcounts, often in the middle of the night.
- the guards would use every opportunity to punish the prisoners.
- after their rebellion was put down the prisoners became subdued
- one prisoner left on the first day after showing signs of psychological disturbance
- two more prisoners were released on the fourth day
- when one prisoner went on hunger strike he was shunned by the other prisoners and was put in ‘the hole’
what conclusions can be drawn from the Stanford Prison Experiment?
guards, prisoners and even the researchers themselves conformed to their role within the prison. even volunteers who came in for just a short amount of time.
what was a strength of Zimbardo’s study?
he had good control of variables. students were randomly assigned to their role and due to the simulated environment the experiment had high internal validity.
what are the weaknesses of Zimbardo’s study?
one criticism is that the prisoners and guards were both just performing what they believed to be the stereotype of a prison. However data collected by Zimbardo during the experiment claimed that 90% of the prisoners expressed the belief that it was a real prison.
Another weakness is that Fromm suggested Zimbardo overplayed the effect of social roles and ignored the influence of personality. only 1/3 of the guards behaved in a brutal or sadistic manner towards the prisoners.
It is also contradicted by the BBC Prison Study in which the prisoners overthrew the guards - this supports their theory of social identity and forming a cohesive group.
what are the ethical issues involving Zimbardo?
Zimbardo had a duel role in the study. not only was he the researcher but also the prison superintendent. he often spoke to the prisoners in this role rather than as a psychologist. he seemed more concerned with the maintenance of his prison than the protection of his participants from undue psychological harm.
what is the meaning of obedience?
a form of social influence in which an individual follows a direct order. the person issuing the order is usually a figure of authority, who has the power to punish disobedience.
outline Milgram’s procedure.
- flyers and adverts to select 40 male ppts aged 20 to 50. they were from a range of areas and professions and were payed $4.50.
- took part in a rigged draw with a confederate, one teacher one learner, ppt always teacher.
- learner supposedly hooked up to a volt machine, in a different room to the teacher. an experimenter in a lab coat gave instructions.
- each time the learner made a mistake (memory task) the teacher gave them a shock.
- started at 15V and went up to 450V. at 300 and 315 the learner would bang on the wall.
- experimenter used four prods - please continue etc.
what were the findings of Milgrams experiment into obedience?
- no participants stopped before 300V
- 12.5% of participants stopped at 300V
- 65% continued to 450V
- Milgram observed that participants would show signs of distress such as sweating, nervous laughter or even ‘seizures’
