de-individuation is a psychological state in which an individual takes on the identity of a social group. Results may be to free the individual from the constraints of social norms and result in anti-social/aggressive behaviour.
zimbardo distinguished between individuated and de-individuated behaviour
de-individuated: behaviours are emotional, impulsive, irrational. loss of self awareness
individuated: behaviours are rational and normative
conditions of de-individuation which promote aggressive behaviours are:
dark
drugs
drink
uniform
anonymity
private self awareness is how we pay attention to our own feelings and behaviours
reduced when we are part of a crowd
pay less attention to our own beliefs and are less self critical
public self awareness is how much we care about what other people think of our behaviour
reduced in crowds
we become more anonymous in a crowd and our behaviour is less likely to be judged by others
we no longer care about how others perceive us and become less accountable for aggressive behaviour
Research by Dodd (ANONYMOUS classroom post it study)
asked students that if they could do anything humanly possible without being detected or held accountable, what would they do
36% of responses involved some form of anti-social behaviour
26% were criminal acts
9% were pro-social
this demonstrates a link between anonymity, de-individuation and aggressive behaviour
Douglass and McGarty (aggressive online chat room behaviour)
found a strong correlation between anonymity and sending threatening/hostile messages online.
the most aggressive messages were sent from those who chose to hide their real identities
this suggests a link between anonymity, de-individuation and aggressive behaviour
Gergen et al (dark room study)
some research studies show that de-individuation does not always lead to aggression
put 8 people in a dark room, telling them that they will never see each other again
social and polite for 15 minutes then got physical 60 minutes in.
at least 80% of the group felt sexually aroused
study repeated but they were told they would see each other afterwards - physical interaction decreased significantly
this study undermines ones of the fundamentals of de-individuation (the idea that de-individuation will lead to aggression)
Johnson and Downing (women costume study)
female participants to give fake electric shocks to a confederate
condition 1 - kkk outfits. condition 2 - nurse outfits. condition 3 - control, ppts in their own clothes.
found that condition 1 gave more severe electric shocks whereas condition 2 gave fewer and were more compassionate towards the victim (prosocial behaviour)
this suggests that both aggression and prosocial behaviour are potential outcomes of de-individuation, depends on normative cues in the situation which is most likely to occur
