Q

neural & hormonal ao3

A

✅ - backed up by science
✅ - coccaro found the amygdala doesn’t operate alone, it works with the orbitofrontal cortex
❌ - biological determinism could lead to social sensitivity
❌ - biological reductionism, ignores any environmental / psychological influences
✅ - studies have shown paroxetine (increases serotonin) leads to lower aggression compared to a control group

Q

maoa gene

A

monoamine oxidase A gene controls the activity of the MAOA enzyme, which breaks down neurotransmitters in the brain into their constituent chemicals. lower MAOA gene activity leads to lower MAOA enzyme activity, which is associated with aggression

Q

genetic influence ao3

A

❌ - coccaro twin study, all share the same environment, therefore a variable that could affect aggression
❌ - rhee and waldman, meta analysis issues
❌ - brunner, maoa activity is all correlational, could be a third variable between maoa and aggression?
❌ - biological determinism could lead to social sensitivity
❌ - leans too far toward nature

Q

what does the ethological explanation say about aggression

A

that it is adaptive, because aggression is beneficial to survival because a defeated animal is forced to establish territory elsewhere

Q

ritualistic aggression

A

a series of aggressive behaviours in animals that are carried out in a set order, they are meant to threaten the other animal, because killing the other animal could endanger their species. showing claws, displaying teeth etc.

tinbergen
studied stickleback fish (have red spots on their back) with a series of wooden blocks. wooden blocks with red spots always caused the sticklebacks to be aggressive and show a fixed action pattern
26
ethological explanation ao3
❌ - animal studies cannot be generalised to humans ✅ - the idea that aggression is adaptive is supported by the evolutionary explanation ❌ - biological determinism ❌ - research is correlational, you can't establish cause and effect ❌ - fixed action patterns can be altered and learned by stimuli.
27
evolutionary explanation
cuckoldry, mate-retention strategies, bullying
28
cuckoldry and its effect on aggression
cuckoldry in our ancestors was seen as a waste of resources as you are investing into children that will not pass on your own genes - this has led to evolved aggression in the form of mate-retention strategies
29
mate-retention strategies
mate-retention strategies are performed by men towards their partners, and ensure fidelity in order to avoid cuckoldry. they are shown by direct guarding, such as tracking your partner on your phone and constantly asking where shes going, and negative inducements, threats of dire consequences if your partner shows infidelity, e.g i'll kill myself if you break up with me
30
shackleford
studied IPV in heterosexual couples, 107 couples filled out questionnaires, men filled out a mate-retention inventory, woman filled out the spouse influence report. found a strong positive correlation between mate-retention strategies and reports of physical violence.
31
bullying
bullying is adaptive, as in our ancestors it could increase chance of survival by promoting their own resources, and increasing chance of reproduction
32
evolutionary explanations ao3
✅ wilson found women who reported MRS were 2x more likely to suffer physical violence ❌ - alpha bias, does not include why women could be aggressive, exaggerates the differences between men and women ❌ - most studies are self report which could be affected by social desirability bias, or positive illusions in relationships ❌ - studies of IPV are correlational, could be a third variable which affects aggression ❌ - biological determinism ❌ - all IPV studies are socially sensitive
33
social learning theory
operant conditioning (direct and indirect) and self efficacy
34
operant conditioning on aggression
aggression can be learnt by being directly reinforced, e.g being aggressive and being rewarded for it aggression can be learnt vicariously, through watching people be aggressive and be rewarded for it, you are then likely to imitate that behaviour mediational processes consist of attention, retention, reproduction, motivation
35
self efficacy
the extent to which we believe our own actions will lead to positive outcomes
36
james bulger case
jon venables got the idea of the murder from watching chucky, the way they killed james mirrored chuckys actions in the film
37
social learning theory of aggression ao3
❌ - ¡kung san people of the kalahari desert are never taught aggression because it is frowned upon, but children still show aggression showing it must be affected by something other than learning ❌ - environmental reductionism, doesn't include biological influences on aggression ✅ - allows for free will in choosing to imitate aggression instead of being programmed to imitate aggression once it is observed ❌ - does not explain children who show reactive aggression instead of just aggression to gain a reward
38
frustration aggression hypothesis
blocked from achieving goals, aggression is not always direct
39
john dollard
formed the FA hypothesis, stated that aggression is always the outcome when we are prevented from achieving our goals. it is based in the psychodynamic theory of catharsis, views aggression as a psychological drive akin to biological drives such as hunger
40
if our attempt to achieve a goal is blocked, we:
- experience frustration - leads to an aggressive drive - leads to aggressive behaviour
41
aggression is not always directed to the source, because:
1) it is an abstract cause, such as society 2) the source has too much power, e.g a teacher being able to give you detention 3) the source is not currently present
42
geen
gave ppts an impossible puzzle to solve, which was either impossible, deatured a confederate who would mess it up, or a confederate who would insult you. aggression was measured after by shocks given to the confederate while they completed their own task. the strongest shocks were given by the insulted group, lowest by the impossible puzzle group
43
weapon effect
presence of aggressive environmental cues stimulate aggression
44
frustration aggression ao3
❌ - berkowitz said frustration just creates a readiness for aggression, there are other factors which cause aggression to be displayed ✅ - studies have shown that aggression is often aimed at innocent people when the source is not available, supporting the idea that aggression is not always aimed at the source ❌ - environmental reductionism, doesn't include biological influences ✅ - trigger can pull the finger hypothesis has real world application in america, where guns are able to be openly carried there is highest levels of gun violence
45
deindividuation theory
anonymity in a crowd leads to lower self awareness
46
what is deindividuation
when in a crowd, or in uniform, we lose our sense of identity and adopt the beliefs / behaviours of the group. this leads to deindividuation, and we act in ways we would never usually think about because we have diminished responsibility. when individuated, we act morally and conscientiously, when deindividuated we lose this and act impulsively, often aggressively
47
private and public self awareness
private: what you think about yourself public: what you think others think about you
48
dodd
asked a class anonymously what they would do for 24 hours if they would never be detected. 36% were antisocial behaviour, 26% was criminal behaviour
49
deindividuation ao3
❌ - in a study where ppts either dressed up as KKK or nurses, the nurses showed affection to people, which is not included in the theory, as it states that all uniform leads to deindividuation, in turn causing aggression ✅ - deviation in the dark, strangers in a pitch black room for an hour became intimate with eachother, supportimg the idea that we act in ways we usually wouldn't when deindividuated ❌ - however, they did not act aggressively, which limits the theory that deindividuation leads to aggression ❌ - deindividuation in a crowd may just be conformity instead of deindividuation ❌ - environmental determinism, not everyone will follow the crowd as we have free will ✅ - online, anonymous chatrooms have higher levels of aggression that non-anonymous
50
institutional aggression
deprivation, importation
51
what is institutional aggression
refers to aggressive behaviour within a formal, controlled environment such as a prison
52
what is a dispositional explanation
anything that explains the cause of behaviour as existing within the persons personality
53
importation model
irwin & cressey said that a culture of aggression is brought into prison due to the inmates backgrounds
54
what is a situational explanation
anything that explains the cause of behaviour as existing within the environment
55
what is the deprivation model
clemmer said that aggression is caused by the prison environment, as conditions are poor and normal human rights are stripped, which causes stress, leading to aggression
56
delisi institutional
studied 813 juvenile offenders in california, inmates with higher dispositional elements were more likely to engage in suicidal activity and sexual misconduct
57
institutional aggression ao3
✅ - real world application, led to improving conditions to decrease aggression in prisons ✅ - delisi had large sample size ❌ - delisi based on self report, which is not reliable, subject to social desirability bias, demand characteristics ❌ - no difference in aggression between high and low security prisons, meaning the deprivation model is not accurate because the different environments do not impact aggression ✅ - both deprivation and importation work better together, an interactionist approach, less reductionist
58
what is media
media is any form of communication that delivers information, data, entertainment etc such as the news, books, films, music, tv,
59
what are video games
video games are usually played on screen using a mouse, keyboard or controller. they involve first person shooters, simulations, adventure, sports or role playing games etc
60
bartholow & anderson
experimental study - ppts played mortal kombat or pga golf, and aggression was tested by noise blasts against a confederate (opponent). loudest noise blasts occurred after the more violent game, mortal kombat
61
delisi video games
correlational study on 227 juvenile offenders, through interviews and questionnaires. he found that the most aggressive inmates played the most video games.
62
robertson
longitudinal study on children and their video game usage. they found that the people with the highest video game usage were the most likely to commit violent crimes as adults
63
anderson
meta analysis on studies similar to the ones before, found video games was associated with levels of aggression
64
video games ao3
❌ - bartholow & anderson, noise blasts is not a valid measure of aggression ❌ - bartholow & anderson, no video games is purely non aggressive, even golf is competitive therefore aggressive ✅ - delisi, large sample size ❌ - delisi, correlation does not equal causation ✅ - robertson, longitudinal means no individual differences ❌ anderson, meta analysis issues
65
what is desensitisation
when exposed to aggression / violence, we undergo physiological and psychological arousal. when exposed frequently to aggression / violence, this arousal decreases, normalising it in our brain, we are therefore more likely to act aggressively / violently
66
what is disinhibition
the weakening of social constraints against certain behaviours, these behaviours then temporarily seem socially acceptable, increasing the likelihood of them occurring in that person.
67
what is cognitive priming
how violent images provide us with ready made scripts about what aggression looks like, this is stored in memory and then can be triggered when we perceive aggressive cues in a situation
68
weisz & earls
showed ppts 'straw dogs' with a graphic rape scene, and then asked to watch a rape trial. ppts who didnt watch the film were more compassionate towards the victim
69
huesmann
said that cognitive priming scripts are stored in memory and so we can be readily primed for aggression
70
D, D, CP ao3
✅ greitemeyer showed male ppts sexually aggressive songs and measured their aggression afterwards. they were measured as more aggressive compared to men who listened to neutral songs ❌ - cognitive priming happens over years, priming based on a couple songs is not accurate to its impact ✅ - aggression is more likely to be shown after watching films where violence is justified, therefore making it seem more socially acceptable ✅ - produce effective intervention strategies to reduce aggressive behaviour, real world application ❌ - environmentally reductionist and determinist
