Background: This study investigates the social psychology of tyranny. Zimbardo
(1973)- carried out an infamous experiment in the basement of
Standford university. It had to be stopped early due to guard
brutality and prisoner distress.
Aims: 1. To provide evidence of the unfolding interactions between groups of unequal power.
2. To investigate if dominant group members will identify with their group from the start and
impose their power. 3. To investigate if subordinate group members will identify collectively
and challenge intergroup inequalities when relations between groups are seen as
impermeable and insecure. 4. To measure the social, organisational and clinical effects of the
study on the participants. 5. To develop a practical and ethical framework for examining social
psychological issues in large-scale studies.
Participants
from 332 applicants, 27 men were
selected by a three-phase screening
process. A final 15 were chosen (to
ensure diversity of age, social class
and ethnic background
Authors claimed that the final 15
were randomly divided into 2
groups of 5 gaurds and 10
prisoners - However this was
done after they had been put into
matched groups of 3. (did this to
make sure personality types were
spread across the guards and
prisoners.
1. battery of psychometric tests that measured
both social variables (authoritarianism, modern
racism) and clinical variables (depression,
anxiety, self harm, ethnic background e.t.c
2. participants underwent a full
weekend assessment by independent
clinical psychologists
3. Medical and character references were
obtained and police checks were conducted
sample obtained through national press
leaflets, no females were involved and so
the sample was not representative of
everyone, people gave consent, diverse
sample.
role of being a guard: they were informed
they have the role of guards, they were
shown a prison timetable, told they were
responsible for the prison running
smoothly they had to draw up prison rules.
They were given well made uniforms.
role of being prisoners: heads shaven, given
uniform (t-shirt with 3-digit number, lose
trousers and flimsy sandals) they were given
no info on prison rules only told violence
was not permitted.
Method
IV's: Permeability of roles (opportunity
for promotion) - Legitimacy of roles
(prisoners told there were no real
differences between them and guards) -
Cognitive alternatives (new trade union
prisoner introduced)
daily psychometric testing and swabs of saliva to test
cortisol levels which can indicate persons stress levels.
guards had better
living quarters,
uniforms, superior
food, snacks and
extra drinks.
prisoners could get snacks or
cigarettes as rewards. They
has their heads shaved and a
t-shirt, trousers and sandals.
They were only given rules
lasted 8 days (reached its
'natural point of termination)
findings
social identification- prisoners
were more identified than the
guards. This was predicted.
depression- Guards depression went
up and up the more they lost control
(permeability)how did the announcement of
permeability affect the prisoners: made
them better behaved and they tried to
impress the guards.
(permeability) How did the
prisoners act after the promotion:
prisoners acted more collectively
against guards, there was no goal
they were working towards so they
tried to annoy the guards.
(legitimacy) intervention was not
necessary: because of the way the groups
emerged naturally, created a sense of
illegitimacy. (prisoners acted collectively,
guards failed to act as a group)
(cognitive alternatives) McCabe was
introduced to bring cognitive alternatives,
but since these were already apparent
McCabe might not have been needed.
McCabe helped offer further
alternatives to the status quo
(especially regarding the
guard/prisoner relationship)
Quantitative measures show how cognitive
alternatives to the status quo became more
apparent to participants throughout the study.
conclusion
E.V: high- unequal
power represented like
in actual prisons
(prisoners locked up
and guards have better
living conditions)
E.V: low- wasn't a
real prison, or real
prisoners and it only
lasted 2 weeks and
they could leave
whenever they
wanted.
conclusions: 1. It is possible to carry
out large scale research 2. people dont
automatically abuse power that they
are given, it depends on how they fit-in
with a group.
reliability- high as they
used data from saliva
swabs to confirm the
psychometric results
Validity- on T.V so hight
demand characteristics,
not a real prison either so
their is a low validity
Unlike Zimbardo- they found that
people dont automatically
assume roles given to them
An experimental case
study, of the behaviour of
members in dominant or
subordinate positions and
of the developing
relations between them.
data collection
observational data
the prison set-up was designed so that all
participant could be both audio and video
recorded (at all times). All audio channels
and 4 video channels were recorded at any
one time throughout the study.
self report data
participant completed a daily set of
psychometric tests to prevent test fatigue,
not every test was given every day
biochemical measures
a daily saliva swab was taken, from
which measures of cortisol were taken,
as an indication of stress levels
