Q

A

If the model had a red underbelly then the stickleback would attack it however if there was no red underbelly then nothing happened. He also found that the FAP displayed were unchanging between different encounters

Q

What is meant by the term cuckoldry?

A

When a male raises another man’s child

30
Q

What is evidence of the evolutionary explanation for aggression?

A

Sexual jealousy

31
Q

What causes sexual jealousy?

A

When men are at risk of being cuckoldry

32
Q

What are two male retention strategies?

A

Direct guarding and negative inducements

33
Q

Give an example of direct guarding.

A

Overinvolvement in their partner’s life E.G checking who they’ve been seeing

34
Q

Give an example of negative inducements.

A

Issuing threats of dire consequences E.G “ill kill myself if you leave me”

35
Q

What research supports retention strategies?

A

when women were asked to report on male retention strategies by measuring the extent they agreed with statements such as “does he insist on knowing where you are?”. Those who had experienced these statements were twice as likely to have experienced physical violence

36
Q

How is bullying explained through evolution?

A

Bullying may have been used by our ancestors in order to promote their own health and create opportunities for reproduction

37
Q

What research supports the view that bullying is evolutionary?

A

Volk et al argued that characteristics associated with bullying are attractive to females. This is because bullying can ward off potential rivals

38
Q

Why and how would women bully?

A

By means of controlling a partner. Females use verbal bullying to keep their partners fidelity (resource provision)

39
Q

What is the frustration-aggression hypothesis?

A

Frustration always leads to aggression

40
Q

What are the three recognitions made by the FA hypothesis?

A

Causes of frustration may be abstract, too powerful or unavailable at the time

41
Q

Outline research into the weapon effect.

A

Participants were given fake electric shocks by a confederate which caused anger and frustration. The PPs were then given the chance to shock the confederate back while presented with weapons E.G guns on a table

42
Q

What were the findings of research into the weapon effect?

A

The number of shocks issued by the PPs was greater when there were two guns on the table compared to other conditions.

43
Q

What research supports the frustration-aggression hypothesis?

A

Groups were given a jigsaw to complete while under specific conditions such as:
an impossible jigsaw
running out of time due to a confederate
being insulted every time they failed

44
Q

What were the findings of the frustration-aggression hypothesis research?

A

The insulted participants gave the strongest shocks followed by the group that ran out of time and then the impossible task group. All shocks were more intense compared to a control group

45
Q

What are the social psychological explanations of aggression?

A

Social learning theory
De-individuation

46
Q

How does SLT explain aggressive behaviour?

A

Vicarious reinforcement- When a child observes aggressive behaviour being rewarded

47
Q

What are the cognitive conditions for learning?

A

Attention
Retention
Reproduction
Motivation

48
Q

What is meant by self-efficacy?

A

the extent to which we believe our actions will achieve a desired goal

49
Q

How can Bandura’s BoBo doll study support SLT and aggression?

A

The study outlined how aggressive behaviour can be imitated by children through vicarious reinforcement

50
Q

How can de-individuation cause aggressive behaviour?

A

we lose self-awareness as well as stop regulating and monitoring our own behaviour

51
Q

what is private self-awareness?

A

when we regulate our own behaviour. This is reduced when in a crowd

52
Q

what is meant by public self-awareness?

A

refers to how much we care what other people think. This is reduced in crowds

53
Q

Outline research into de-individuation.

A

229 participants were asked the question “if you could do anything without consequences what would you do?” Only 9% of responses were prosocial and 26% were criminal acts. 36% were antisocial behaviours.

54
Q

What is the importation model in the context of aggression in prisons?

A

Inmates in prisons are aggressive due to the prison being an accumulation of people from typically aggressive backgrounds

55
Q

What is the deprivation model explanation of aggression in prisons?

A

Harsh environments (such as prisons) cause inmates to cope by resorting to aggressive behaviour

56
Q

What are two explanations of institutional aggression?

A

Dispositional and Situational

57
Q

What research linked aggression to excessive TV viewing?

A

1000 New Zealanders TV watching patterns were observed. It was found that time spent watching TV in childhood and adolescence was a reliable predictor of aggressive behaviour in early adulthood. This is due to excessive TV being linked to reduced social interaction.

58
Q

What did Bandura do to link aggression with viewing violent content?

A

He repeated the BoBo doll study with a video of adults hitting the doll. They found that the behaviour was replicated regardless of it being face to face or viewed through a screen

59
Q

What evidence is there to suggest that the effects of TV violence is not that strong?

A

Meta-analysis of previous research found a positive correlation between viewing violence and anti-social behaviour however TV/film only accounted for about 1-10% of the variance in children’s aggressive behaviour

59
Q

How was Mortal Kombat used to demonstrate how aggression is linked to violence?

A

Players were given the opportunity to blast (fake) opponents with white noise after playing 10 minutes of a game. Those who played Mortal Kombat were more aggressive when blasting white noise at their opponents

60
Q

How can we become desensitised to aggression?

A

overexposure to aggression through the media creates lesser arousal associated with the sympathetic nervous system

61
Q

How does disinhibition cause aggression?

A

Environmental triggers weaken normal social constraints towards certain behaviours. This makes those behaviours temporarily socially acceptable

62
Q

How does cognitive priming explain aggression?

A

violent imagery creates scripts about aggression which are stored in memory. These memories are triggered when we perceive a situation to be aggression

63
Q

How does Mertins et al support the MAOA-L gene?

A

Proved the opposite happens with the MAOA-H gene as PPS with MAOA-H who played the money distribution game were extremely cooperative and less agitated

64
Q

What did Goodall observe with monkeys that limits ritualistic aggression?

A

She observed a four year war between two monkey communities in which they killed one another

65
Q

Which African Tribe did Elizabeth Thomas find that reject all acts of aggression?

A

!Kung San people

66
Q

What is the frustration aggression hypothesis’s suggestion of Catharsis?

A

By acting aggressively we satisfy our unconscious need to do so resulting in the end to aggressive behaviour

67
Q

What did Busman find regarding Catharsis?

A

acts of aggression, such as using a punching bag, actually increased aggression instead of satisfying it

68
Q

What did Douglas and McCarthy find in regards to anonymity in online chatrooms?

A

The greater anonymity of the person the more hostile they were

69
Q

What were the concordance rates of aggression found by Coccaro?

A

Monozygotic twins = 50%
Dizygotic twins = 19%

70
Q

How many real life instances of “crowd encouraged suicides” did Mann identify?

A
