Social learning theory	Bandura, Ross and Ross; Johnson; Noble
Bandura, Ross and Ross	affect of role models on aggressive behaviour. gender effect
Johnson et al	found that play aggression in children was highly correlated with actual aggression.
Noble	Reports overhearing a little girl.
Deindividuation	Festinger et al, Zimbardo, Malmuth and Check. Zimbardo et al, Postmes and Spears
Festinger et al	proposed a theory based on Le Bons 'crowd theory' where anonymity of being in a crowd means that individuals feel less responsible for their actions. Then a 'collective mindset' takes over the crowd and normally repressed aggressive acts occur
Zimbardo	Disagreed with Le Bons 'collective mindset' he said that anonymity leads to a release from self restraints against negative behaviours, increased emotional behaviour, increased irrational thinking, and increase in impulsive behaviour
Malmuth and Check	1/3 would rape, Us students
Zimbardo et al	Stanford prison, ethical problem had to be stopped
Postmes and Spears	Conducted a meta analysis but found mixed results, many studies did not support theory of deindividuation
Institutional aggression	Irwin and Cressey, Sykes, Irwin and Cressey 2, Cheeseman, McCorkle et al
Irwin and Cressey	proposed importation model, three subcultures; Crime/theft, Convict, Conventional 'straight'
Sykes	identified five deprivational factors;liberty (freedom), autonomy (cannot decide what happens to them daily), goods/services (possessions), heterosexual relationships, security (fear for their own safety)
Irwin and Cressey 2	found that one off offenders were percieved by others as 'straight' and not part of the aggressive subculture
Cheeseman	found that it was not deprivation itself that leaded to aggression but the fact it increased stress levels
McCorkcle et al	Found that deprivation model did not explain aggression in prisons and that bad management was much more important as was, high staff turnover, lack of staff dicipline
Genetic factors	Professor Jim Fallon, Cases et al, Brunner at al, New et al
Proffessor Jim Fallon	real world example; had a faulty copy of MAOA and brain activity of a psycho. he had a good upbringing, does not show high levels of aggression
Cases et al.	Created mice without the MAOA gene. These mice lack serotonin, demonstrated inc levels of aggression. Also suggested the lack of a working copy of MAOA inc aggressive behaviour
Brunner et al	found that males in a large Dutch faily all had a faulty copy of the MAOA and were all aggressive when angry, fearful or frustrated
New et al	Found the the HTR1B influences serotinin levels also involved in aggressive behaviour, suggesting MAOA is reductionist

Daly et al	Found that men are most likely to be violent when their partners are unfaithful
Harris	conducted a meta analysis and found women affected my emotion, men by sexual
Evolutionary explanations of group displays	Maynard-Smith and Parker, Schwarz and Barkey, Sua Peter, Blalock

Schwarz and Barkey	found that sports teams win more home games due to group displays
