Social Influence Flashcards
Define conformity
Change in person’s behaviour/opinion as a result of real or imagined pressure from a person/group
Define compliance
- Superficial + temporary
- Publically go along w/ group but privately disagree
- Change only lasts as long as group is present
Define identification
- Moderate
- Act same as group bc value it + want to be part of it
- Don’t agree w/ everything majority believes
Define internalisation
- Deep
- Take on majority view bc we accept it as correct
- Leads to permanent change even if group is absent
Define informational social influence
- Agree w/ majority bc accept it as correct + want to be correct
- Leads to internalisation
- Occurs when: situation is ambiguous
Define normative social influence
- Agree w/ majority bc want to be accepted + gain social approval
- Leads to compliance
- Occurs when: need social approval + w/ familiar people
Evaluate ISI
(+) Research support - Lucas et al, students ans maths problems (easy/hard). More conformity when hard esp w/ students who rated maths skills as poor.
(-) Individual diff - Perrin + Spencer found engineering students conformed less. More knowledgeable = less influenced by majority
Evaluate NSI
(+) Research support - Asch asked ppts why they agreed w/ wrong ans - felt self-conscious + afraid of disapproval
(-) Individual diff - nAffiliators (people w/ greater need for social relationship) are more likely to conform
Outline Asch’s procedure into conformity
- Recruited 123 American male students - each tested individually w/ group btw 6-8 confed
- Each trial ppts identified length of standard line
- Each participated in 18 trials
- 12 critical trials- confed gave wrong ans
Outline Asch’s Findings + conclusion
- Ppts gave wrong ans 36.8% of the time
- 25% ppts never gave wrong ans, 75% at least once
- Most said they conformed to avoid rejection (NSI) + privately disagree w/ majority (compliance)
What were the variables that Asch changed in his study?
- Group size
- Unanimity
- Task difficulty
Outline how group size affected conformity in Asch’s research
- No. confed varied btw 1-15
- Conformity:
- W/ 2 : 13.6%
- W/ 3 : 31.8% - adding more made little diff
Outline how unanimity affected conformity in Asch’s research
- Added accurate/inaccurate dissenter
- presence of dissenter: dec 25% - enabled ppts to behave more independantly
Outline how task difficulty affected conformity in Asch’s research
- Made task harder by making lines similar in lengths
- Conformity inc when difficulty inc
- ISI plays greater role when task becomes harder - situation more ambiguous so look to others for guidance
Evaluate Asch’s study
(+) High degree of control - Manipulated lines to make task harder. Variables easy to manipulate
(-) Experiment was artificial - Task was trivial so no reason not to conform. Low ecological validity
(-) Ethical issues - ppts decieved, told visual line judgement task.
(-) Cultural bias - Smith + Bond suggest conformity rates higher in collectivist (37%) than individualist (25%)
Outline the procedure of Zimbardo’s study into conformity to social roles
- Set up mock prison in Stanford uni
- 24 emotionslly stable students determined by psychological testing - randomly assigned roles
- Prisoners arrested at homes + blindfolded, strip searched, deloused + issued no. + uniform (deindividuated)
- Guards uniform : wooden club, handcuffs, keys + mirror shades. Told they had complete power over prisoners
Outline Zimbardo’s findings + conclusion
- 2 days : prisoners rebelled against treatment
- Guards became abusive towards prisoners
- Prisoners became passive + accepting
- Both P + G conformed to social roles
- Supposed to last 2 weeks but ended after 6 days
- 5 prisoners released early bc extreme reactions to situation
Evaluate Zimabardo’s study
(+) Conducted ethically - approved by ethics comittee + ppts debriefed
(+) Real world application - explains Abu Ghraib (Iraq prison). Suggests situation factors influence people’s behaviour
(-) Lack realism - acting based on stereotypes. Results lack validity
(-) Unethical - Zimbardo became the superintended. Unable to protect ppts
Define obedience
Form of social influence in which an individual follows direct orders
Outline Milgram’s procedure
- 40 male ppts aged 20-50 (unskilled to professional) through newspaper ads - said memory study
- Drew lots, Mr Wallace was always the learner while ppts was teacher + experimenter wore lab coat
- Learner in another room
- Ppt would give series of inc electric shocks if ans was wrong.
- Started at 15v upto 450v. At 300v learner pounded on wall + gave no response (told treat as wrong ans)
- if teacher unsure, prods given
Outline the prods given to the teacher (ppt) by the experimenter
- ‘Please continue’
- ‘The experimenter requires that you continue’
- ‘It is absolutely essential that you continue’
- ‘You have no other choice, you must go on’
Outline Milgram’s findings and conclusions
- 100% uptil 300v
- 65% uptil 450v
- Ppts were seen to sweat, tremble + groan
- 3 ppts had full blown uncontrollable seizures
- Prior to study Migram asked psy students to predict ppts behviour, said 3% would continue to 450v
- Ppts debriefed + assured behaviour was normal. Follow up questionnaire showed 84% reported they’re glad to have participated
Evaluate Milgram’s study
(+) High external validity - Hofling et al 21/22 nurses willing to give lethal injection following phone instructions from ‘doctor’
(+) Supporting study - French TV show 80% gave 450v to apparently unconsious man
(-) Low internal validity - ppts didn’t believe shocks were real due to calm demeanor of experimentor
(-) Unethical - ppts were decieved
