Social psychological approaches to aggression- deindividuation
Le Bon suggested individuals are more likely to be aggressive when part of a
group. Aggressive behaviour is contagious and therefore individuals have no choice
over if they become aggressive or not.
Zimbardo suggested deindividuation can occur for 2 reasons:
Sense of anonymity in a group meaning you have lower feelings of guilt
Lower inhibitions due to increased arousal
Diener deindividuation occurs when 4 factors occur which as anonymity, increased
arousal, strong group feelings, external focus. This led to reduced self awareness
and then deindividuation.
Prentice- Dunn and Rogers suggested deindividuation is caused by 2 types of self
Reduced private self awareness- lower inhibitions, don't consider
consequences of their actions
Reduced public self awareness- reduced sense of identity
Zimbardo female undergraduates gave shocks to other students and were told it
would aid learning. Half of the participants worse bulky coats and hoods that hid
their faces. They were spoken to in groups of 4 and never referred to by name.
The other half wore normal clothes, large name tags and were introduced to each
other by name. They could all see each other when sat at the shock machines. All
participants were told something about the learner before the experiment to make
the learner appear nice or horrible. Found that hooded participants gave twice as
many shocks and the amount of shocks wasn't influenced by the description of the
learner. Those who wore name tags were influenced by the descriptions of the
learners. This shows that anonymity is causing by wearing masks, hoods and leads
to increased aggression. Low population validity so can't generalise females to
Mann content analysis of 21 newspaper articles about potential suicides
threatening to jump off a tall building and found that in 10 cases people were
more likely to shout jump when part of a group. This shows that factors
influencing deindividuation occur in real life but also that it doesn't always lead to
aggression. Small sample and used newspaper articles so could be biased.

such as listening to rock music in a dark room, verbal interaction with other
participants or playing exciting video games. The other group were told to think
about themselves quietly. When asked to give electric shocks the first group gave
