Evaluation of raine et al

Question 1

methodology and procedures- standardised procedures?

Answer 1

This is a strength
Used matched pairs and all p’s complete cpt

Question 2

Negatives of quasi experiment?

Answer 2

The iv was naturally occurring, it’s difficult to establish a true cause and effect because the criminal behaviour as not manipulated by researchers, therefore we can’t say that is caused by brain activity

Question 3

Methodology of raines study- use of pet scans?

Answer 3

Strength that pet scans were used
Ensuring objective measurement of brain activity, whilst completing the task
Useful as it allows for accurate levels of the brains whilst people are alive
Accurate and objective measurement that can’t be used via post morton that allows brain activity

Question 4

Methodology and procedure- matched pair?

Answer 4

Strength
Because rain matched ps on characteristic’s such as age sex and mental health
Therefore less participant variables

Question 5

matched pairs weekness?

Answer 5

Not matched in all characteristics like ethnicity
Meaning confounding and extraneous variables are there

Question 6

Methodology and procedure sample?

Answer 6

Weekness as the study only contains murderes so therefore it lacks population validity due to the sample oberlpoking individuowe to go commit wd crimes in other natures
Samples overlook muttered who haven’t been declared as murderes

Question 7

Ethics of study- Valid consent?

Answer 7

A weekness as theirs a lack of this becaude can non murderes give convent if their vulnerable
However this topic can be extremely difficult to study so even though theirs no valid consent, do the findings remove the ethical issues

Question 8

Ethics- right to withdrawal?

Answer 8

Was it made clear to the prisoners that set could say no and did they understand what the study was about

Question 9

Ethics- protection from harm?

Answer 9

P’s where kept on medication two weeks prior to reaserch
Could the study’s CPT be difficult stressful and even damaging

Question 10

Social implications- Could it be used to identify criminal behaviour befote it occurs?

Answer 10

We’re now aware of brain area linked to behaviour depending on activity levels, specifically in the prefrontal cortex so this could suggest that someone’s more likely to demonstrate anti social behaviour
Impacting to society because it opens up the door to screen for brain abnormalities in ares which could be used as a preventative measure for individuate believer to be at risk if commting these crimes

Question 11

Social implications- result on judicial system?

Answer 11

Reaserch says it’s biological so could we get less harsh scentences

Question 12

Social implication- school?

Answer 12

self fufilling prophecy

Question 13

Social implication- Hospitals?

Answer 13

Strain on NHS as we can’t scan everyone for precautions

Question 14

Alternative evidence evaluation psychologist?

Answer 14

Raine and yang 2009
James Fallon
Tiihoen at al 2015

Question 15

Alternative evidence- Raine and yang?

Answer 15

Meta anyalyasis of 43 imaging study’s regarding an antisocial and violent behaviour
Finding a link between reduced pre frontal activity in antisocial/violent individuals
Supporting raines research as it should us that internal factors like the brain can cause violent activity
Therefore this is a strength because it supports rain study that murderes and it’s reliable

Question 16

Alternative evidence?
James Fallon

Answer 16

Analysed own genes and found he had the brain characteristics linked to violent behaviour, but he wasn’t a criminal
He had a positive childhood which could have differed to criminals
Perhaps criminals have had a childhood which triggers genetic predisposition
Rejecting rains weekness as it says the even though people have thsi gene it dosney mean they will commit crime
Therefore is weekness as it says ignores external factor

Question 17

Alternative evidence- Tiihoen et al 2015?

Answer 17

Analysed genes of 895 finnish prisoners
Found a link between MAOA gene (dopamine production) and increased likelihood of commuting a crime
Supports raines reaserch as he found evidence for a specific gene linked to violent behaviour, which is known as teh monoamije oxidase. A gene has been linked to the production of dopamine, causing abnormally high levels of neurotransmitter
Findings of this study agree with Raine because both study demonstrate links between the biological makeup or the brain and predisposition to criminal behaviour
Therefore this is a strength as rains research is strongly supported by the link between brain structure and criminal
