Social Lecture 4: Inter-Group Processes Flashcards
Collective behaviour
Refers to relatively large aggregations of individuals who display similarities in action and outlook; also referred to as crowd behaviour
Why could being in a crowd lead to anti-social behaviours? (2)
- de-individuation
Bystander Effect (Diffusion of Responsibility)
In situations where many people are present at an incident there are many reported instances of inaction on the part of the observers
How can crowds lead to positive behaviours?
Characteristics of collectives/crowds (5)
- size
- proximity
- duration
- conventionality
- relationships among members
Le Bon
- 1986
- Believed that crowds foster anonymity but can also generate emotion
- Coined term ‘contagion’
Contagion (2)
- The spread of behaviours, attitudes, and affect through social collectives
- The process whereby irrational and violent feelings can spread through the members of a crowd
Convergency theories (4)
- crowd behaviour is not a product of the crowd itself, but is carried into the crowd by particular individuals
- crowds amount to a convergence of like-minded individuals
- there are similarities among this who join crowds and collectives
- these factors lead to de-individuation
De-Individuation Theory (5)
- feelings of anonymity
- diffusion of responsibility
- membership in large groups
- heightened state of physiological arousal
- individuals become less ‘evident’
De-Individualisation Theory (5)
- feelings of anonymity
- diffusion of responsibility
- membership in large groups
- heightened state of physiological arousal
- individuals become less ‘evident’
What factors can affect the level of de-individuation and how? (2)
- group size
- anonymity
- larger group/ more anonymity = increased de-individuation
Diener 1972
-Children on Halloween entered a house and were told by experimenter “please only take one candy” and researched left children alone with the candy
Diener 1972 Findings (2)
- children who were asked their names and addresses were more likely to only take one candy
- children who were in groups were more likely to take more than one candy than children who entered alone
Festginer 1952
Individuals dressed in grey laboratory coats and sat in dim light were more willing to use bad language when discussing erotic literature than individuals who were not
Mann 1981
Studied 21 instances in which crowds were present where someone was threatening to jump from a building or a bridge
Mann 1981 Findings (2)
- When the crowd was small and it was daytime, people didn’t usually try to get the person to jump
- If it was night time, or the crowd was large (factors which contribute to anonymity) the crowd usually jeered and baited the individual to jump (later research found that crowd formation was associated with variables that increase crowd frustration eg. block traffic etc)
Example of the Bystander Effect
