Agression Flashcards
Neural Mechanisms of aggression
Gospic et al
- Proposer (confederate offers to split money with responder, game performed in fMRI
- Sharp increase in amygdala activity after rejecting the offer
Twin study into aggression
Coccaro
- MZ 50%
- DZ 19%
Adoption study into aggression
Mednick et al
- having criminal bio father increased risk of criminality
- having criminal bio and adoptive father increased risk even more
Genetic explanation MAOA
Stuart
- 97 men in a rehabilitation program for IPV
- Low activity variant were more violent than those with the high activity version
Ethnological explanation fish
Tinbergen
- During mating season, he presented male stickleback fish with various models of rival males, different shapes some with red belly
1. Sign stimulus - red belly
2. Innate releasing mechanism
3. FAP - headbutting
Evolutionary explanation of aggression
Shackelford et al
- Studies IPV in 107 couples
- Strong positive correlation between men’s reports of using retention strategies and women’s reports of physical violence
- DV may be a tool used by men to control their partners and reduce the chances of cuckoldry
Frustration aggression hypothesis support
Geen
- Got people to solve a jigsaw puzzle in one of 4 conditions under a time limit
1. Puzzle was impossible
2. Puzzle can’t be solved because of confederate asking questions to waste time
3. Confederate insults ppt when they make a mistake
4. Control
- After, ppt was required to shock the confederate when he made mistakes on a task, they can choose the voltage
- Order of shock strongest to weakest - 3,2,1,4
Frustration aggression hypothesis counter
Bushman
- Ppt angered by confederate and either hit a punching bag or did nothing then got to blast the confederate with white noise
- Ppts that hit the punching bag blasted white noise for longer than those who did nothing
De-individuation support
Dodd
- 229 psych students asked anonymously “ if you could do anything humanly possible with no consequences what would you do”
- 36% antisocial
- 26% criminal
- 9% good thing
Zimbardo prison experiment
De-individuation counter
Gergen
- Placed groups of 12 in a pitch black room and told to behave however they wanted
- Within half an hour 100% touched by accident, 90% touched on purpose, 80% reported feeling sexually aroused, 50% hugged, some kissed
- When repeated in a fully lit room 5% touched by accident, 0% touched on purpose, 30% reported feeling sexually aroused
- Anonymity led to abnormal behaviour but not aggressive
Institutional aggression support
Edens et al
- Conducted the Psychopathology Checklist - Revised in male sex offenders and how they behaved in prison over the previous two years
- Found a significant relationship between psychopathy and aggression
Institutional aggression counter
Kelly et al
- Conducted Structured Clinical Interview on 353 inmates to see whether having ASPD predicted misconduct in prison
- Found no relationship over a one year period
Outline the Deprivation model
Sykes
- Inmates are deprived of freedom, autonomy, good and services, security/safety, heterosexual intimacy
- These “pains of imprisonment” lead to frustration which may lead to aggression
Deprivation model support
Bierie
- 1738 staff from 114 prisons rated the prison in terms of the physical conditions and number of assaults within the prison
- Worse conditions were associated with more physical assaults
What are the mechanisms of media influences on aggression
Disinhibition
Desensitisation
Cognitive priming
