72
Q

What was Tinbergen’s research involving stickleback fish and fixed action patterns?

A

when presented with an object that was partially red, they will attack it, regardless whether it is fish-shaped or not
animals are innately programmed to respond aggressively

73
Q

How do genetic and neural explainations support the ethological approach to aggression?

A

genetic = aggression is innate, the MAOA gene
neural = the amygdala’s response supports innate releasing mechanism

provides ethological app more credibility and validity

74
Q

How did Lehrman critisise Lorenz’s instinctual explaination of aggression?

A

it underestimates the role of envrionmental factors in the development of species-typical aggressive behaviour patterns
fixed action patterns are not completly innate = learning and experience interact with genetics
cannot make assumptions as variation has been seen within members of the same species

75
Q

Why was Lorenz’s hydraulic model critisised?

A

research has shown that the performance of aggressive behaviour could provide further stimulus which actually makes further aggressive behaviour more likely instead of a reduced likelihood of aggression because of reduced energy

76
Q

What did Goodall find on Chipanzees killing members of their own species?

A

male chipanzees worked together to kill another group of male chipanzees even when appeasement displays were shown
aggression is not always adaptive = contradicts
invalid explaination = based on lower order species like fish and birds not higher order species like chipanzees

77
Q

Who developed the frustration-aggression hypothesis?

A

Dollard

78
Q

What does the FAH state causes aggression?

A

all aggression is the result of frutration and the greater the frustration the greater the aggressive response

79
Q

What is frustration?

A

when you are prevented from acheiving a goal

80
Q

How does frustration cause aggression?

A

frustration causes an arousal of an aggressive drive that leads to aggressive behaviour - acting aggressively provides a cathartic effect

81
Q

What is the cathartic effect?

A

pleasent feelings after releasing a strong emotion - acting aggressivly leads to a reduction in aggressive behaviour

82
Q

What prevents us from acting aggressively according to FAH?

A

fear of punishment

83
Q

What factors increase frustration?

A
  • strong motivation to acheive a goal
  • closer proximity to the goal
  • expectations of acheiving the goal
  • if being aggressive is likely to remove a barrier to the goal
84
Q

How can people learn that being aggressive is helpful to acheiving goals?

A

being aggressive may help them to acheive their goals by removing obstacles and if the aggression doesnt lead to punishment

85
Q

What is displacement for aggression?

A

taking your anger out on something or someone else that is seen as a scapegoat who didnt cause the frustration

86
Q

Why do people displace anger?

A

the source that caused frustration is not availabe
or
fear of punishment if taken out on source of frustration

87
Q

What was Geen’s lab study using puzzles to support the FAH?

A

cause and effect established - lab
ps were deliberately frustrated by a confed while completing a jigsaw
they gave stronger shocks to the confed when he failed a task compared to the non-frustrated control group

88
Q

What was Marcus-Newall et al meta-analysis on displacement supporting FAH?

A

valid - proves theory predictions
49 studies on displacement
ps who were more provoked were more likely to aggress an innocent person than those unprovoked

89
Q

What was Priks study involving football supporters supporting the FAH?

A

real-world app
football supporters were more likely to throw missiles on the pitch and fight with opposition supporters when they were frustrated with the poor performance from their team
the fans good expectations were proved wrong - caused frustration

90
Q

How can the FAH explain mass killings in WW1?

A

real world app
germans blamed jews for loss of war
widespread frustration cause manipulation by propaganda
shows aggression towards a scapegoated group

91
Q

What is an issue with research on catharsis?

A

has little research support = more studies disprove it

92
Q

What was bushman’s study disproving the catharsis effect?

A

unvalid
ps who repeatedly hit a punch bag became more angry, doing nothing reduced aggression
FAH - should be reduced aggression

93
Q

What did Berkowitz state on frustration causing aggression?

A

frustration doesnt always cause aggression and aggression can occur without frustration
unpleasent experiences, one is frustration, triggers negative feelings that lead to aggression

94
Q

What was Berkowitz’s revised FAH theory?

A

the negative affect theory = negative experiences (one being frustration) lead to negative feelings that causes aggression

95
Q

What was Reifman et al’s baseball players study supporting Berkowitz’s negative affect theory?

A

baseball players were more aggressive when the temp was higher rather than they were frustrated

96
Q

What does the SLT state how aggression occurs?

A

aggression is learnt through observation of role models in a social context, people imitate behaviour depending on mediational factors

97
Q

What did Bandura state increases imitating aggression?

A

is the role model is someone we strongly identify with - same sex, same age

and if you see them being rewarded = vicarious reinforcement

self-efficacy

98
Q

What reduced imitation according to bandura?

A

vicarious punishment = watched role model being punished for a behaviour - aggression

99
Q

What is self-efficacy?

A

confidence in your own ability to carry out an action

100
Q

How is self-efficacy developed?

A

if they imitate a behaviour and it was successful - more confident to repeat it

101
Q

How does bandura bobo doll support SLT of aggression?

A

empirical support - valid
children learn through observation and imitation of models

102
Q

What is the issue with Bandura’s bobo doll study?

A

artificial and lacks realism—-> low eco valid and non- applicable
bobo doll does not hit back like a human would - tells us little about everyday aggression

103
Q

What was Gee and Leith’s hocky players study supporting SLT in aggression?

A

North american hockey players were more aggressive than european players
NA players exposed to aggressive role models and less likely punished for aggressive behaviour
aggressive behaviour is acquired through seeing the consequences of other peoples behaviour

104
Q

How can SLT of aggression be useful for explaining aggression in different situations?

A

explains why someone can be aggressive in 1 situation but not another = mediational processes involved like motivation
can predict behaviours by considering consequences

105
Q

How does the SLT explain cultural differences in aggression?

A

valid theory
aggression not valued in some cultures - punished and not observed
if children exposed to an aggressive role model- aggression is more likely

106
Q

Why is any social psychological explaination of aggression not a complete explaination?

A

they ignore bio factors and focus on nurture
biology creates potential for aggression but expression of aggression is learned

107
Q

What are the 3 social psychological explanations of aggression?

A

social learning theory
frustration-aggression hypothesis theory
de-individuation

108
Q

What is de-individuation?

A

the loss of personal identity and personal responsibility characterised by a reduction in self evaluation and less concern for others

109
Q

When does de-individuation occur?

A

in a large group

110
Q

Who developed de-individuation?

A

Zimbardo

111
Q

How does being in a large group lead to aggression?

A

gives people ‘a cloak of anonymity’ that diminishes any personal consequences for their actions
less concern about negative evalution from others and therefore a reduction in guilt or shame

112
Q

What are the 2 factors affecting deindividuation?

A

anonymity - uniforms
altered consciousness due to drugs or alcohol

113
Q

How do uniforms increase aggression through individuation?

A

its more difficult to identify an individual - anonymity
reduces inner restraints for personal and social norms = they behave in a way they wouldnt normally

114
Q

How does Zimbardo’s prison experiment support deindividuation?

A

guards were individuated and acted aggressively towards the prisoners

115
Q

What are the issues with zimbardo’s prison expt, for de-individuation?

A

artificial setting = low ecological valid, doesnt reflect deindividuated behaviour in real life
ps behaving to stereotypes of guards being aggressive towards prisoners

116
Q

What was zimbardos study using female ps to support de-individuation?

A

4 female undergrads
gave another student electric shocks to aid learning
condition 1 = bulky lab coats, as a group given instructions, not introduced
condition 2 = own clothes, individually given instructions, name tags and introduced

deindividuated condition 1 have shocks x2 as long

Q

What was Johnson and downing study on uniforms and de-individuation?

A

dressed ps in a mask and overalls like the KKK
or dressed as nurses

ps with masks and overalls gave higher shocks than control group
nurses gave lower shocks
other factors involved like the social roles we play as the rates should be equal if only uniform was a factor

118
Q

What was Watson’s cross cultural study on de-individuation?

A

warriors in 23 societies changed their appearance for conflict
those who changed their appearance with war paint and tribal costumes were more aggressive = hard to distinguish people

119
Q

What is the practical app of de-individuation?

A

more street lighting and CCTV in areas known for anti-social behaviour
people are aware they are being watched and identified = less likely to commit anti-social acts
useful theory

120
Q

How does the de-individuation theory have a narrow application?

A

aggression occurs in situations where the perpetrators are not deindividuared = eg road rage - identified by a number plate
only applies to certain situations

121
Q

What was Spivey and Prentice-Dunn findings on pro-social behaviour and deindividuation?

A

deindividuation can lead to pro-social behaviour when prosocial environmental cues were present like a prosocial model
not a valid theory
eg protests and religious gatherings

122
Q

How is de-individuation gender biased?

A

deindividuation is more likely the cause of aggression in males than females

123
Q

What are the 2 explainations for institutional aggression?

A

the importation model and the deprivation model

124
Q

What is the dispositional explaination of institutional aggression?

A

the importation model

125
Q

What is the situational explaination of institutional aggression?

A

the deprivation model

126
Q

Who came up with the importation model?

A

Irwin and Cressey

127
Q

What is the importation model state causes institutional aggression?

A

prisoners bring their own beliefs and values into prison with them = they are not ‘blank slates’ when they enter prison
aggression is a way of establishing power, status and access to resources
aggression is not the product of the environment
if there are enough individuals who value the aggression it will become the norm

128
Q

What 3 studies support the importation model?

A

Harer and Steffensmeirer
Poole and Regoli
Mears et al

129
Q

What was Harer and Steffensmeirer’s study on importation vairables like race?

A

58 US prisons
found black inmates had significantly higher levels of violent behaviour but lower rates of alcohol and drug-related misconduct than white inmates
these patterns parrallel racial differences in these behaviours in US society

130
Q

What did Poole and Regoli find on juvenile delinquents?

A

for juvenile deliquents the best predictor of inmate aggression was pre-insitutional aggression

131
Q

What was Mears at al study on cultural beliefs systems and inmate aggression?

A

the inmates ‘code of street’ outside of prison correlated to the level of violence within the prison
mostly true for inmates that lacked family support and were involved in gangs
practical apps

132
Q

What are the practical applications of research on the importation model?

A

possible to predict which prisoners are most likely to be aggressive in prison by looking at their outside behaviour = can arrange them in prison accordingly

133
Q

What are issues with the importation model?

A

ignores the role of the prison environment as a factor
androcentric - not valid

134
Q

What doe the deprivation model say causes inmate aggression?

A

aggression is a product of the stressful and oppressive conditions of the institution
aggression is a way to reduce stress, (cathartic) obtain desired resources and gain control over their lives
aggression is the result of the prison environment

135
Q

What did skyes find the common factors of prisons mostly lead to aggression?

A

loss of freedom
loss of relationships
boredem
lack of security
over-crowding
heat
noise

136
Q

What 4 studies support the deprivation model?

A

De lisi et al
McCorkle
Steiner
Wilson

137
Q

What was delisi et al study supporting deprivation model and disproves the importation model on street gangs

A

prisoners with prior street gang involvement were NO more likely to behave more aggressively than others in prison
prisons tend to isolate gang members from other prisoners to avoid violence

138
Q

What was McCorkle’s study on deprivation factors?

A

looked at 371 prisons in the US and found factors such as overcrowding, lack of meaningful activity and lack of privacy significantly linfluenced inmate assaults on both other inmates and staff

139
Q

What did Franklin et al find suggesting that the deprivation model is affected by individual differences?

A

crowded prison conditions increased aggression in younger prisoners aged 18-25 more than older ones

140
Q

What was Wilson’s study on changing prison conditions to support the deprivation model?

A

he changed the prison conditions so that they were less overcrowded, less noisy, cooler and added windows
this eradicated assaults on inmates and staff
they should make prisons a more comfortable environment

141
Q

What are the issues of the deprivation model?

A

importation model more valid = stronger explaination
evidence for Import and deprivation are contradictory = interactionist app should be taken
androcentric

142
Q

What are media influences?

A

changes in behaviour that are attributed to exposure to media such as TV or computer games

143
Q

What was Anderson et al (2000) lab study on media influences on aggression?

A

there was a short term increase of physiological arousal, hostile feelings and aggressive behaviour
measured arousal, hostility and aggressive behaviour
student ps blasted their opponents with white noise for longer after playing an aggressive game compared to a non-violent game (puzzle) and they rated themselves higher on the hostility scale

144
Q

How was hostility measured in Anderson et al (2000) lab study?

A

self- report = ps rated themselves on a hostility scale

145
Q

How was arousal measured in Anderson et at (2000) lab study?

A

blood presure and heart rate

146
Q

What are the good things with Anderson et al (2000) lab research?

A

lab = c and e, confidence in results
EV are controlled = internal validity

147
Q

What are the issues with Anderson et al (2000) lab study?

A

lacks eco valid = blasting white noise is artificial, does not involve retaliation = limits generaliability
only measures short term effect
student sample = specific, possible co-v as they could play more games than younger and older people
self-report = subjective, social desiribility bias, lacks internal valid

148
Q

What was DeLisi et al correlational study on computer games effects on aggression?

A

227 juvenile offenders with history of aggressive behaviour
structured interviews
found a significant correlation with how often they played violent CG and how much they enjoyed them with their level of aggression
computer games is a significant risk factor for aggression

149
Q

What are the good things withe DeLisi et al’s correlational study on CG and aggression?

A

high pop valid = 227 sample size, representative
better temporal validity than lab experiment = 2013
structure interviews = rich in detail, more comfortable
realistic forms of aggression = they had commited violent acts, externally valid

150
Q

What are the issues with DeLisi et al’s correlational study on CP and aggression?

A

no C and E = less applicable, less control of EVs eg: upbringings and backgrounds
lacks generalisability (low pop valid) = specific sample= juvenile delinquents
social desirability bias for interviews

151
Q

What was Anderson et al (2007) longitudinal study on CP influence on aggression?

A

x430 7-9 year olds
surveyed at 2 points of the school year by questionaire to the child, peers and teachers
children who had high exposure to violent video games were more verbally and physically aggressive and less pro-social behaviour
long-term effects of video games on aggression

152
Q

What are the good things about Anderson et al (2007) long study on CP and aggression?

A

large sample = representative
looked at long term effects which has little research
giving questionaires to peers and teachers = improves internal validity

153
Q

What are the issues about Anderson et al (2007) long study on CP and aggression?

A

sample = children may find it difficult to complete questionaire, specific = low pop valid,
questionaires = children may have exaggerated answers
correlational = no C and E
Co-Vs = role models, cannot control them

154
Q

What is an issue with all research on computer games and aggression?

A

they are deterministic = ignores free will
ignores other factors like males have more testosterone and are also more likely to play violent computer games as they are targeted towards males
it assumes that all people who play video games are aggressive

155
Q

How are individual differences ignored in research on computer games and aggression?

A

people with a more aggressive personality type may engage in a more aggressive style of game-playing
age = younger players have a more impressionable brain so their morals are not yet developed
upbringing = if aggression was promoted or not

156
Q

What are the 3 explainations for media influences of aggression?

A

desensitisation
disinhibiton
cognitive priming

157
Q

What is desensitisation?

A

habitually viewing agressive CP diminishes the impact of violence leading to less anxiety and physiological arousal
also leads to negative attitiudes towards violence weaken and less empathy for victims

158
Q

Why does desensitisation lead to aggression (empathy explaination)?

A

repeated exposure to violence leaves us less sensitive to the state of victims
empathy inhibits us from acting aggressively, however, constant exposure dulls our empathetic responses and people are not inhibited from acting aggressive

159
Q

What 2 studies support desensitisation?

A

Bushman
Carnagey et al

160
Q

What was Bushmans study on desensitisation?

A

ps took longer to help someone injured in a fight after plaing 20 mins of a violent game compared to ps playing a non-violent game = reduction in empathy

161
Q

What are the issues with Bushman’ study?

A

replications failed to find the same result = less valid
not direct measure of empathy

162
Q

What was Carnagey et al’s study supporting desensitisation?

A

ps played a violent game for 20 mins
then shown a 10 min video of real life violence
ps had lower heart rate and skin conductance (sweating) compared to control who played a non-violent game

163
Q

What are the issues with Carnagey et al’s study?

A

artificial = low eco valid as they are not in the actual situation, simply watching a video so low emotional response

164
Q

What is the issue of desensitisation with individual differences?

A

media exposure is widepread however we are not all affected the same way and equally
must be other life experiences or genetic predispositions as there are individual differences in desensitisation experienced

165
Q

Who came up with disinhibition?

A

Berkowitz

166
Q

What is disinhibiton?

A

people are naturally aggressive however, the impulses to act aggressive are held in check by social and psychological inhibitions
these inhibitions are learnt through social transmission
repeated exposure = leads to new social norms where aggression is socially accepted

167
Q

What is the issue with disinhibiton and individual differences?

A

the extent in which someone becomes involved in the media they experience will vary
may only occur in people fully engage and not those easily distracted by external stimuli
or in households with strong normas against violence
narrows the no. of people who can be affected this way = less applicable and generalisable

168
Q

What study goes against disinhibition?

A

Goranson = boxing study

169
Q

What was Goranson’s study on diinhibition?

A

showed ps a boxing match with 2 diff endings = death or no consequences
ps who saw no consequences were more likely to be aggressive than those who saw the death
disinhibition is more likely when no consequences are shown

170
Q

What is cognitive priming?

A

the activation of existing aggressive thoughts and feelings

171
Q

How does cognitive priming explain why children act aggressively after watching aggression on TV?

A

they are primed to act aggressively because a network of memories are retrived to act aggressively
frequent exposure = children store scripts for aggressive behaviour, these can be recalled in later situations if any cue from the original situation is present

172
Q

What 2 studies support cognitive priming?

A

Anderson and Dill
Murray et al

173
Q

What did Anderson and Dill find to support cognitive priming?

A

individuals who played violent CP had more cognitive accessible aggressive thoughts than individuals who played non-violent games
a single incident of violent game primed aggressive thoughts in ps

174
Q

What was murray et al’s study supporting cognitive priming?

A

fMRI on children and they were shown aggressive or non-aggressive films
there was an increase in activity in the area of the brain associated with memory and emotion when watching aggressive film
memories were formed which can later react to cues
scientific

175
Q

What is an issue with research on cognitive priming?

A

it is correlational = no C and E
agressive people could choose to watch violent media not the media causing aggression
