Festinger, Pepitone and Newcomb -
deindividuation. Process of immersion
within a group due to sense of
anonymity. Includes effects of social
context rather than 'group mind'
Zimbardo (1969) - anonymity
and aggression. Diffusion of
responsibility - across group and
violence becomes more likely
Deiner & Prentice-Dunn and
Rogers - anonymity does not
inevitably lead to
deindividuation
Deiner - other factors such as
emotional arousal, sense of
group cohesion and focus on
external events may lead to
deindividuation
Inputs (anonymity, arousal, external focus,
group cohesion) -- Deindividuation (loss of self,
decreased concern for social evaluation,
diffusion of responsibility) -- Outputs (impulsive
irrational behaviour, aggression,
responsiveness to immediate surroundings,
distorted perception)
Le Bon and the
psychology of the mob
argued that
individual
rationality is lost
when in a crowd
by 'group mind'
individuals experience
primitive, unconscious
and aggressive instincts
Contagion -
susceptible to
suggestion. Feels
anonymous and less
personally
accountable
Criticisms - views based
on political bias, drew
mainly on personal
observations and didn't
spend much time in crowds
