Q

What is the issue with saying serotonin influences aggression?

25
What is testosterone?
an androgen (male sex hormone) secreted by the testes little sectreted by the ovaries
26
What is the link between aggression and testosterone?
higher levels of aggression = higher levels of testosterone
27
Between what ages do males produce the most testosterone?
15-25 = the group most likely to commit violent crimes
28
What did Wagner do to mice to study testosterone's affect on aggression?
castrated male mice = aggression reduced injected testosterone = aggression increased castration has been used for domestic animal and farm animals
29
What was Dabbs study on testosterone in male prisoners?
measured testosterone in the salia of 692 adult male prisoners higher levels in more violent offenders = committed unprovoked acts of violence
30
What was Carre's dual-hormone hypothesis?
high levels of testosterone lead to aggressive behaviour only when cortisol levels are low
31
What happens when cortisol levels are high?
testosterone's influence on aggression is blocked
32
What type of behaviours does testosterone increase?
status-seeking behaviours = aggression is 1 of them
33
What is the genetic theory of aggression?
genes are the cause of aagressive behaviour and it can be passed on from 1 generation to the next
34
What gene is found to have an influence on aggression?
the MAOA gene
35
What is the role of the MAOA GENE?
responsible for regulating the enzyme MAOA
36
What is the role of the MAOA enzyme?
breaks down neurotransmitters serotonin, noradrenaline and dopamine, removing excess amounts and allowing neurons to communicate more effectively
37
How does the MAOA gene cause aggression?
if there is a dsfynction in the MAOA gene, the enzyme doesn't regulate the levels of serotonin properly = aggressive behaviour
38
What are the 2 forms of the MAOA gene?
L variant = low activity H variant = high activity
39
Which form of the MAOA gene is likely to lead to aggression?
L varient
40
What did Brunner find on a Dutch family in terms of the MAOA gene?
the male family members had been particularly aggressive over many generations there was a rare mutated version o the MAOA gene in the family researchers discovered the 2 forms of the gene
41
What was McDermott's study involving hot sauce and the MAOA gene?
the MAOA-L gene was more likely to force someone to eat hot chilli sauce despite having to pay than someone with the MAOA-H gene
42
What was Caspi's study on anti-social behaviour in male kids and the MAOA gene?
500 male children looked at their anti-social behaviour when they grew up L variant support in aggression BUT only if they had been maltreated as children = the right environment causes aggression, genetics simply predispose an interactionist app should be taken
43
What was Lagerspetz selective breeding study and the MAOA gene?
lab based selective breeding isolate a group of mice interbred the aggressive mice so that after 19 generations, the rates of aggression were x10 higher
44
What other findings did Lagerspetz find on aggressive mice?
the aggressive mice had heavier testes and forebrains altered levels of serotonin and noradrenaline genes influence both structural and functional aspects of an animal's biology
45
What was Coccaro's study on twins and the MAOA gene?
used a questionaire to measure hostility in male ps concordance rates: MZ = 50% DZ = 19% genetic factors play a part but the environment is important too
46
What is the evolutionary explaination of aggression?
suggests that present day behaviours come from our remote human ancestors because they were adapting and these behaviours proposed an advantage for surviving, reproducing and passing on their genes
47
What are the 2 ways that aggression can be seen as evolutionary?
sexual competition sexual jealousy
48
What is sexual competition?
competing with other males to win access to females - aggression was needed to eliminate competition
49
What is sexual jealousy?
males feared losing their mate to another male so they need to find and retain their mates is the root of majority of male aggressive behaviour
50
What has sexual jealousy led to in terms of adaptive responses?
mate-retention strategies to enhance reproductive fitness and to avoid fear of cuckoldry
51
What is cuckoldry?
raising offspring that isnt your own without knowing
52
Why does the evolutionary approach to aggression say females are less aggressive?
females are less aggressive = her survival is crucial for the survival of her offspring
53
What is Puts' findings on physiological features supporting sexual competition?
mals have 75% more muscle mass than females = men have evolved as a result of fighting each other men with the strongest bones and muscles would have been able to fight off competition easier = more likely to pass on genes
54
What was found on women who have been abused and sexual jealousy?
women who have been beaten by their male partners recall extreme jealousy on part of their husbands or boyfriends as the key cause of aggression
55
What did Daly and Wilson find on sexual jealousy and violence?
men have evolved different stategies to deter their partners from acts of infedility = guarding, spying, threats and violence sexual jealousy was the underlying factor in 58 out of 214 murder cases
56
What is the practical application of research done on male tactics in sexual jealousy?
particular tactics can be early indicators of violence can be used to alert friends and family to the danger signs that can lead o further violence
57
How is the evolutionary explanation of aggression gender bias?
cannot account for female violence towards a male partner recent family conflict studies show that there are equal rates of assaults by men and women
58
How are gender differences in aggression accounted for by the evolutionary app?
women are more likely to engage in verbal violence than physical verbal aggression is less risky in terms of being hurt = more likely to survive for children
59
How does the evolutionary app to aggression have a deterministic view?
sexual jealousy is determined by genetic factors ove which we have no control
60
How does the evolutionary app in aggression support nature AND nurture?
genes predispose males to sexual jealousy but other factors such as the culture, childhood experiences influences how this manifests itself
61
What is an issue with the evolutionary app not supporting free will?
there is a danger that lack of free will can be used to justify crimes against women
62
What is the role of ethologists?
they study animal behaviour in natural environments in the context of evolutionary theory
63
What does Lorenz suggest on aggression (ethological)?
aggression is an adaptive instinct which has evolved to aid survival for different reasons
64
What are 3 ways aggression aids survival of animals?
1. ensures only strongest and fittest males pass on genes 2. disperse members of species more widely so resources are exhasusted less quickly and disease has less impact 3. maintain hierachy in socially organised animals
65
What are innate releasing mechanisms?
built-in structure in the brain that when triggered by environmental stimuli, causes a series of fixed action patterns
66
What are fixed action patterns?
sequence of pre-programmed, ritualistic behaviours carried out in a set order, triggered by an innate releasing mechanism
67
What is the role of fixed action patterns in animals?
deter another male away to prevent their genes from being passed on due to access to females and teritory
68
What did Lorenz state about fixed action patterns?
not designed to start physical fights = animals do not want to kill each other as it would cause the species to die animals show appeasement displays
69
What is an appeasement display?
an action from an animal that signals to another animal that they surrender
70
What is Lorenz's action specific energy?
ritualistic signals can only occur for a certain amount of time as fixed action paterns only have a certain amount of energy dedicated to them
71
What is Lorenz's hydraulic model?
ritualistic signals can occur in the absence of a sign stimuli if too much action specific energy builds up
72
What was Tinbergen's research involving stickleback fish and fixed action patterns?
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
How do genetic and neural explainations support the ethological approach to aggression?
genetic = aggression is innate, the MAOA gene neural = the amygdala's response supports innate releasing mechanism provides ethological app more credibility and validity
74
How did Lehrman critisise Lorenz's instinctual explaination of aggression?
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
Why was Lorenz's hydraulic model critisised?
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
What did Goodall find on Chipanzees killing members of their own species?
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
Who developed the frustration-aggression hypothesis?
Dollard
78
What does the FAH state causes aggression?
all aggression is the result of frutration and the greater the frustration the greater the aggressive response
79
What is frustration?
when you are prevented from acheiving a goal
80
How does frustration cause aggression?
frustration causes an arousal of an aggressive drive that leads to aggressive behaviour - acting aggressively provides a cathartic effect
81
What is the cathartic effect?
pleasent feelings after releasing a strong emotion - acting aggressivly leads to a reduction in aggressive behaviour
82
What prevents us from acting aggressively according to FAH?
fear of punishment
83
What factors increase frustration?
- 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
How can people learn that being aggressive is helpful to acheiving goals?
being aggressive may help them to acheive their goals by removing obstacles and if the aggression doesnt lead to punishment
85
What is displacement for aggression?
taking your anger out on something or someone else that is seen as a scapegoat who didnt cause the frustration
86
Why do people displace anger?
the source that caused frustration is not availabe or fear of punishment if taken out on source of frustration
87
What was Geen's lab study using puzzles to support the FAH?
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
What was Marcus-Newall et al meta-analysis on displacement supporting FAH?
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
What was Priks study involving football supporters supporting the FAH?
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
How can the FAH explain mass killings in WW1?
real world app germans blamed jews for loss of war widespread frustration cause manipulation by propaganda shows aggression towards a scapegoated group
91
What is an issue with research on catharsis?
has little research support = more studies disprove it
92
What was bushman's study disproving the catharsis effect?
unvalid ps who repeatedly hit a punch bag became more angry, doing nothing reduced aggression FAH - should be reduced aggression
93
What did Berkowitz state on frustration causing aggression?
frustration doesnt always cause aggression and aggression can occur without frustration unpleasent experiences, one is frustration, triggers negative feelings that lead to aggression
94
What was Berkowitz's revised FAH theory?
the negative affect theory = negative experiences (one being frustration) lead to negative feelings that causes aggression
95
What was Reifman et al's baseball players study supporting Berkowitz's negative affect theory?
baseball players were more aggressive when the temp was higher rather than they were frustrated
96
What does the SLT state how aggression occurs?
aggression is learnt through observation of role models in a social context, people imitate behaviour depending on mediational factors
97
What did Bandura state increases imitating aggression?
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
What reduced imitation according to bandura?
vicarious punishment = watched role model being punished for a behaviour - aggression
99
What is self-efficacy?
confidence in your own ability to carry out an action
100
How is self-efficacy developed?
if they imitate a behaviour and it was successful - more confident to repeat it
101
How does bandura bobo doll support SLT of aggression?
empirical support - valid children learn through observation and imitation of models
102
What is the issue with Bandura's bobo doll study?
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
What was Gee and Leith's hocky players study supporting SLT in aggression?
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
How can SLT of aggression be useful for explaining aggression in different situations?
explains why someone can be aggressive in 1 situation but not another = mediational processes involved like motivation can predict behaviours by considering consequences
105
How does the SLT explain cultural differences in aggression?
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
Why is any social psychological explaination of aggression not a complete explaination?
they ignore bio factors and focus on nurture biology creates potential for aggression but expression of aggression is learned
107
What are the 3 social psychological explanations of aggression?
social learning theory frustration-aggression hypothesis theory de-individuation
108
What is de-individuation?
the loss of personal identity and personal responsibility characterised by a reduction in self evaluation and less concern for others
109
When does de-individuation occur?
in a large group
110
Who developed de-individuation?
Zimbardo
111
How does being in a large group lead to aggression?
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
What are the 2 factors affecting deindividuation?
anonymity - uniforms altered consciousness due to drugs or alcohol
113
How do uniforms increase aggression through individuation?
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
How does Zimbardo's prison experiment support deindividuation?
guards were individuated and acted aggressively towards the prisoners
115
What are the issues with zimbardo's prison expt, for de-individuation?
artificial setting = low ecological valid, doesnt reflect deindividuated behaviour in real life ps behaving to stereotypes of guards being aggressive towards prisoners
116
What was zimbardos study using female ps to support de-individuation?
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
117
What was Johnson and downing study on uniforms and de-individuation?
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
What was Watson's cross cultural study on de-individuation?
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
What is the practical app of de-individuation?
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
How does the de-individuation theory have a narrow application?
aggression occurs in situations where the perpetrators are not deindividuared = eg road rage - identified by a number plate only applies to certain situations
121
What was Spivey and Prentice-Dunn findings on pro-social behaviour and deindividuation?
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
How is de-individuation gender biased?
deindividuation is more likely the cause of aggression in males than females
123
What are the 2 explainations for institutional aggression?
the importation model and the deprivation model
124
What is the dispositional explaination of institutional aggression?
the importation model
125
What is the situational explaination of institutional aggression?
the deprivation model
126
Who came up with the importation model?
Irwin and Cressey
127
What is the importation model state causes institutional aggression?
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
What 3 studies support the importation model?
Harer and Steffensmeirer Poole and Regoli Mears et al
129
What was Harer and Steffensmeirer's study on importation vairables like race?
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
What did Poole and Regoli find on juvenile delinquents?
for juvenile deliquents the best predictor of inmate aggression was pre-insitutional aggression
131
What was Mears at al study on cultural beliefs systems and inmate aggression?
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
What are the practical applications of research on the importation model?
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
What are issues with the importation model?
ignores the role of the prison environment as a factor androcentric - not valid
134
What doe the deprivation model say causes inmate aggression?
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
What did skyes find the common factors of prisons mostly lead to aggression?
loss of freedom loss of relationships boredem lack of security over-crowding heat noise
136
What 4 studies support the deprivation model?
De lisi et al McCorkle Steiner Wilson
137
What was delisi et al study supporting deprivation model and disproves the importation model on street gangs
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
What was McCorkle's study on deprivation factors?
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
What did Franklin et al find suggesting that the deprivation model is affected by individual differences?
crowded prison conditions increased aggression in younger prisoners aged 18-25 more than older ones
140
What was Wilson's study on changing prison conditions to support the deprivation model?
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
What are the issues of the deprivation model?
importation model more valid = stronger explaination evidence for Import and deprivation are contradictory = interactionist app should be taken androcentric
142
What are media influences?
changes in behaviour that are attributed to exposure to media such as TV or computer games
143
What was Anderson et al (2000) lab study on media influences on aggression?
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
How was hostility measured in Anderson et al (2000) lab study?
self- report = ps rated themselves on a hostility scale
145
How was arousal measured in Anderson et at (2000) lab study?
blood presure and heart rate
146
What are the good things with Anderson et al (2000) lab research?
lab = c and e, confidence in results EV are controlled = internal validity
147
What are the issues with Anderson et al (2000) lab study?
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
What was DeLisi et al correlational study on computer games effects on aggression?
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
What are the good things withe DeLisi et al's correlational study on CG and aggression?
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
What are the issues with DeLisi et al's correlational study on CP and aggression?
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
What was Anderson et al (2007) longitudinal study on CP influence on aggression?
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
What are the good things about Anderson et al (2007) long study on CP and aggression?
large sample = representative looked at long term effects which has little research giving questionaires to peers and teachers = improves internal validity
153
What are the issues about Anderson et al (2007) long study on CP and aggression?
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
What is an issue with all research on computer games and aggression?
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
How are individual differences ignored in research on computer games and aggression?
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
What are the 3 explainations for media influences of aggression?
desensitisation disinhibiton cognitive priming
157
What is desensitisation?
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
Why does desensitisation lead to aggression (empathy explaination)?
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
What 2 studies support desensitisation?
Bushman Carnagey et al
160
What was Bushmans study on desensitisation?
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
What are the issues with Bushman' study?
replications failed to find the same result = less valid not direct measure of empathy
162
What was Carnagey et al's study supporting desensitisation?
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
What are the issues with Carnagey et al's study?
artificial = low eco valid as they are not in the actual situation, simply watching a video so low emotional response
