Bandura: 'We learn through observations of others.' Five stages: 1. Observation - children
learn through observation of role models and imitate behaviour, including aggression. 2.
Reinforcement - if the behaviour is seen to be rewarded it is vicariously reinforced and
'worth repeating'. 3. Mental Representation - children form a mental representation of the
social situations that their behaviour will be rewarded in. 4. Direct Experience - if children
are rewarded for their aggressive behaviour (e.g. suspended = day off school!) they are
likely to repeat the same action in similar situations - this is known as direct
reinforcement. 5. Self-efficacy - if the child is good at aggressive acts (i.e. they get the
desired result) then their confidence in their ability to be aggressive increases
Supported by Bandura's Bobo doll Study: 72 3-5 year old children were split into 3 groups. Group 1 saw
aggressive behaviour towards the doll, group 2 saw non-aggressive behaviour and group 3 was a control
group (no previous interaction). The children were then given a bobo doll to play with. Group 1 replicated a
great deal of the aggressive behaviour (both physical and verbal), groups 2 & 3 exhibited virtually no
aggressive behaviour towards the doll. Boys produced more physical violence than girls but there was no
gender difference in verbal aggression. The gender of the role model had a significant influence on whether
the behaviour was imitated - more likely to imitate the behaviour if the role model was the same gender
This is supported by Bandura and Walter's 'consequence endings'
study. Three groups of children saw a film of an adult being aggressive
to the doll: group 1 saw the adult rewarded for their actions, group 2
saw the adult punished and group 3 saw no consequences (control).
In subsequent play; group 1 showed high levels of aggression, group
2 showed low levels of aggression and group 3 showed medium
levels of aggression - supporting the role of vicarious reinforcement
Ethical Issues: Protection of
participants - exposing children to the
positive reinforcement of aggression
may be detrimental in later life
Can be used to account for individual
differences in aggression - it depends if
it is reinforced positively or negatively
Aronson - explains cultural variations: US
society is highly violent but the Pygmies
of central Africa are very peaceful -
different responses to aggression
Questionable Validity - Nobel reported a child
saying "look mummy, there's a doll we have to
hit" - it's only a toy, not a human, so may think
this is how you're supposed to play with it
Age Bias - only young children
studied, can't be generalised to adults
Phillips found that the daily homicide rates in the US
increased the week following a major boxing match, suggesting
adults imitated the aggressive behaviour they had seen
Strong Face Validity - it explains how
the behaviour of role models e.g. TV
stars, can be imitated and makes sense!
RWA: censorship of aggression in media, e.g.
don't show aggression being rewarded. NCT
classes for parents to reach them how to deal
with aggressive children and NOT reward htem
Deindividuation
Nota:
Defined by Reber and Reber as the 'loss of one's sense
of identity' - deindividuation refers to the process of
decreased self-assessment and awareness in situations
where the identification of an individual is very difficult .
Deiner - 4 things cause lack of
self-awareness: 1. Poor self-monitoring. 2.
Reduced need for social approval. 3. Reduced
inhibitions. 4. Reduced rational thinking
Deiner conducted a naturalistic observation if 1,300
trick-or-treating children in the US. When the children were in
large groups and wearing costumes they were likely to perform
anti-social acts such as stealing sweets or money as the group
reduces the possibility of personal identification
Age Bias -
children have less
self-awareness
anyway!
No control of
Extraneous Variables
- less valid
Could be prone
to observer bias
Large Sample Size
- more reliable
Zimbardo suggests that people
normally refrain from acting in
an aggressive manner partly
because there are social norms
inhibiting such 'uncivilised'
behaviour and partly because
they are easily identifiable
Supported by Zimbardo's study. Similar to Milgram - teachers and
'learners' (confederates). Female P's played the teacher and had to
administer electric shocks when the answer was wrong. In one condition
the Ps wore large lab coats and hoods, were talked to in groups of 4
and never referred to by name (deindividuated). In the other condition,
Ps wore their normal clothes, large name tags and were introduced to
each other formally. All Ps could see the learner. They were also told
that the learner was either 'honest' or 'conceited and critical'.
Irrespective of the description of the learner, deindividuated Ps
delivered twice as many shocks as the 'individuated' group - who tended
to give different amounts of shocks depending on the description given
Gynocentric - can't be
generalised to men
Ethical Issues: Deception, Informed
Consent, Protection from Harm
Lacks Mundane Realism
and Ecological Validity
Silke analysed 500 violent attacks occurring in Northern Ireland. 206 of these were
carried out by people who wore a disguise so their individual identity was not known.
The severity of violent actions was linked to weather the perpetrator was masked or not
A major criticism of deindividuation is that it doesn't explain why not all
crowds and groups are aggressive - for example the Hindu festival of
Mela. Cassidy observed the festival and found crowds behaved well and
increased generosity, support and orderly behaviour was noted
Institutionalisation
Situational Forces
(Deprivation Model)
Zimbardo thought people (specifically prisoners and guards)
behave as they do because of the situation they are placed in.
Both display a lack of respect for each other because of the
social role expected of them in a prison situation.
Supported by Zimbardo's Stanford Prison Experiment: 24 men, 12
'prisoners', 12 'guards'. All had a mental health screening before the
experiment began and deemed 'normal' - not aggressive. Prisoners
given numbers and uniform. Guards given uniform and reflective
sunglasses - deindividuation was an important part of the process.
The guards grew increasingly tyrannical - would wake prisoners in the
middle of the night and make them clean toilets with their bare hands
etc. They played their roles even when they were unaware of being
watched. The whole experiment ended after 6 days out of fear for the
prisoners safety despite the intention to continue for two weeks
May be subject to Demand Characteristics as Ps
were asked to play a specific role, and many of the
guards later claimed they had just been acting
Unethical: no
protection from harm
RWA: Zimbardo was
asked to testify about
prison reform and caused
US Congress to change a
law regarding juveniles
being housed with adult
criminals before their trial
Individualistic Forces
(Dispositional Model)
Irwin and Cressey created the 'importation model'
claiming that prisoners bring their own social histories
and traits with them into prison, and this influences their
adaptation to the prison environment. They argue that
prisoners are not 'blank slates' when they enter prison and
they will 'import' their normativer system into the prison.
The idea that aggression comes from the individual
themselves, not as a result of systems or institutions.
Harer and Steffensmeier found that age,
education level and race were all important
factors to producing aggression. In a survey
of 58 US prisons, black inmates had
significantly higher rates of violent behaviour
but lower rates of alcohol/drug-related
misconduct than white inmates. This
parallels the racial difference in these
behaviours in US society, suggesting that it
is one's personality or disposition that
creates violence within institutions
Culture Bias - Western,
can't be generalised
One of the most violent guards from the Stanford Prison
Experiment was white and came from a well educated,
middle-class family. His levels of violence do NOT parallel
the behaviour of others in this social group - suggesting that
he did not 'import' them into the prison situation
Institutional aggression involves the behaviour of
those people serving in institutions (police, military
etc) as well as criminal and terrorist groups
