social influence Flashcards
(109 cards)
what did zimbardo et al (1973) do?
- set up a mock prison in basement of psych dep at stanford
- selected 21 student male student volunteers
- randomly assigned to play role of guard/prisoner
- both encouraged to conform to social roles both through uniforms + instructions about behaviour
what was zimbardo’s aim?
wanted to know why prison guards behave so brutally - whether because they have sadistic personalities or it was their social role that created such behaviour
how were uniforms and instructions about behaviour used in the SPE?
- the uniforms created de-individuation meaning they would be more likely to conform to the perceived social role
- prisoners = loose smock to wear + cap to cover hair + identified with number (names never used)
- guards = own uniform reflecting status of role + wooden club, handcuffs + mirror shades
- further encouraged to identify with role with several procedures
ex: - rather than leaving study early prisoners could ‘apply for parole’
- guards encouraged by being reminded had complete power over prisoners
what were the findings of the SPE related to social roles for guards?
- guards took roles with enthusiasm + treating prisoners harshly - within two days prisoners rebelled - ripped unforms - shouting + guards retaliated with fire extinguishers
- harassed prisoners constantly reminding them powerless - ex conducted freq headcounts when prisoners stand in line + call out numbers
- highlighted diffs in SRs by creating opps to enforce rules + admin punishments
- guards identified more + more closely with their role - behaviour became increasingly brutal + aggressive - some appearing to enjoy power
- when one prisoner went hunger-strike- force feed + punish by putting him in tiny dark closet
what were the findings of the SPE related to social roles for prisoners?
- after rebellion put down prisoners became subdued, depressed + anxious
- one released - symptoms of psychological disturbance - two more released on fourth day
- zimbardo ended study after 6 days instead of intended 14
what are the conclusions of the SPE related to social roles?
- social roles appear to have strong influence on individuals behaviour - guards became brutal + prisoners submissive
- such roles easily taken on by all ptps - even volunteers who came to perform specific functions found themselves behaving as if were in a prison rather than psych study
how did the uniforms create deindividuation?
- prisoners dehumanised by wearing loose fitting smock, nylon stocking cap + referred to by number not name
- guards - wearing uniform, reflective sunglasses + bring referred to only as ‘mr. correctional officer’
evaluation for SPE
- control
- real-life app
- realism
- 1/3
what are strengths of the SPE?
- control - zim + colleagues had control over key variables - selection of ptps - emotionally-stable individuals chosen + randomly assigned to roles guard/prisoner - can rule out individual personality diffs as exp of findings - if guards + prisoners behaved diff + in those roles by chance - beh due to role - internal validity = high - supp roles in conf
- real-life application
what are limitations of the SPE?
- lacks realism - one guard claimed based his role on brutal character from a film - shows performances were artificial
- findings of SPE tell us little about conformity to social roles in actual prisons
- exaggeration of power of social roles - only 1/3 behaved in brutal manner - most guards able to resist situational pressures to conform - zim minimised influence of dispositional factors
- ethical issues - ptps subdued, depressed + anxious + one left after 2 days - zim did not halt - failed in duty to protect their welfare
what was Milgram (1963) aim?
- wanted to assess obedience levels
- see whether people would obey figure of authority when told to harm another person
what was Milgram’s (1963) procedure?
- 40 male volunteers - paid $4.50
- each ptp introduced to conf upon arrival - drew lots on who would be ‘teacher’ (T) and ‘learner’ (L - called mr wallace) - lot fixed so ptp always teacher
- an ‘experimenter’ also involved who was a conf
- learner - strapped to chair + wired up with electrodes - had to remember pair of words each time made error ptp had to give electric shock via switches on ‘shock machine’
- from slight to intense to danger-severe - when teacher 300 volts L pounded on wall + no response to next q
- 315 again pounded but silent rest procedure
- when ptp refused to administer shock - experimenter gave series of prods
what were the four standard ‘prods’ the experimenter used to get the teacher to continue?
prod 1 - ‘pls continue’/’please go on’
prod 2 - ‘the exp requires that you will continue’
prod 3 - ‘it is absolutely essential that you continue’
prod 4 - ‘you have no other choice, you must go on’
what were the baseline findings of Milgram (1963)? what was the qualitative data?
- all ptps went up to 300v
- 65% went up to 450v - fully obedient
- 12.5% stopped at 300v
- he collected qdata including observations: ptps showed signs of extreme tension - sweating, stuttering , biting lips + three had seizures
what did milgram do after the study?
all ptps in baselin - debriefed + assured beh = normal + sent follow-up questionnaire - 84% glad to have ptp
what does germany have to do with Milgram (1963)?
- he wanted to know why such high prop of germany obeyed hitler’s inhumane requests
- thought possible explanation - germans diff from people from other countries - perhaps more obedient
- to determine this needed a procedure to assess how obedient people are
what were the conclusions of Milgram (1963)?
- concluded german people are not ‘different’ - american ptps willing to obey even when might harm another
- suspected certain factors in situation - encouraged obedience - conducted further studies to investigate
what is obedience?
form of SI where individual follows a direct order - person issuing usually figure of authority who has power to punish
what are strengths of Milgram’s study?
- due to the controlled laboratory nature of exp - every ptp completed exact same procedure - can be replicated - The Game of Death-documentary - ptp believed they were contestants in a pilot episode for new game show - paid to give electric shocks to other ptps (actors) - 80% of the participants
delivered the max shock 460v to an apparently unconscious man - beh almost identical - anxiety signs - reliable - not just due to special circumstances - ptp cared for after - carried out role as a psych - same mental state - after the exp stopped- either when the experimenter used all verbal prods/max voltage reached- all ptps thoroughly de-briefed + de-hoaxed - 84% reported that they felt glad to have participated
- Milgram also kept in touch years after - make sure study left no lasting mental or physical damage
what are weaknesses of milgram?
- low internal validity - ptps behaved the way they did because guessed the shocks were not real - so milgram didnt test what he intended to - Perry listened to tapes of ptps + reported many expressed doubts about shocks
- Androcentric study-data cannot be generalised to females - sample included all men
- ethics - some ptps shaking, laughing hysterically; nervously giggling, sweating heavily + one participant had a seizure
what are the situational variables which can affect obedience as investigated by milgram (1963)?
- situational variables
- proximity
- location
- uniform
what was Milgrams proximity variation like? what were the findings? explanation?
- teacher could hear learner but not see him in baseline
- in proximity variation - teacher + learner in same room - obedience rate dropped to 40%
- in touch proximity - dropped 30%
- remote instruction - reduced 20.5%
- decreased proximity allows people to psychologically distance themselves from consequences of actions - in baseline when seperated ptp less aware of harm so more obedient
what was Milgrams location variation like? what were the findings? explanation?
- conducted in run-down office block - obedience fell to 47.5%
- prestigious uni environment gave study legitimacy + authority - ptps more obedient in location bc perceived experimenter shared this legitimacy + obedience expected
what was Milgrams uniform variation like? what were the findings? explanation?
- in baseline experimenter wore grey lab coat as symbol of his authority
- in one variation experi called away at start + replaced by ordinary civilian (conf) in everyday clothes
- obedience dropped to 20%
- uniforms encourage obedience bc widely recognised as symbols of authority
- accept someone in a uniform entitled to expect obedience bc authority legitimate
- someone without - less right to expect obedience
