Q

Amygdala and aggression- Coccaro 2007?

A

Studied people with intermittent explosive disorder in comparison to controls
Each participant viewed images of faces whilst using fMRI scans
-P’s with IED showed high levels of amygdala activity when they viewed angry faces in comparison to controls thus demonstrating an association between the amygdala and the processing of aggressive emotions

Q

Amygdala and aggression- how does coccaro explain criminal behaviour?

A

Social cues of aggression are processed differently by the brain in those who have IED
This dysfunction of the brain could explain aggressive tendencies that make them more vulnerable to criminal behaviour

Q

A&FC- why can the dysfunction of the amygdala lead to aggressive behaviour?

A

Person is more aggressive and anti social, more likely to commit crimes, never learned that its not okay as fear conditioning is disrupted

Q

A&FC- how can fear conditioning explain criminal behaviour?

A

Explaining all participants have never learnt what’s right or wrong within their lives so therefore when they are older they may commit crimes as they dont understand severity of consequence

Q

A&FC- gao et al?

A

A longitudinal study in 1795 at 3 years old and p’s assessed on fear conditioning via getting through tests of physical arousal like sweating through painful notice
-20 years later and the ps with no fear conditioning committed crimes at 23

Q

Raine et al- what did he find in the amygdala?

A

Hemispheric asymmetry in the amygdala function
-Reduced left and greater right activity
- Difference producing unusual emotions responses like lack of fear empathy remorse and guilt

Raine et al- explanation of criminal behavior from findings?

A

Q

Evaluation- supporting evidence?

A

S- One strength
E- Gao et al (in flashcards before) aggression in 3-23
E- Explains crimes as children ultimately never learnet what’s right or wrong so ay commit crimes and not understand the consequence or severity, as amaugla has failed
W- Therefore research shows an association between the role of amygdala and criminal behaviour

Q

Evaluation- Other brain areas?

A

S- One weakness is that there are other brain areas that impact criminality not just amygdala
E- The amygdala does not operate on its own it’s part of a wider system of connected brain structures, orbitofrontal cortex
E- The prefrontal cortex is responsible for our motivation and the inhabitation, Rain found that in the PF cortes there are lower glucose metabolism compared to control group
W- Therefore dysfunction of amygdala on its own may not be enough alone to account for criminal behaviour

Q

Evaluation- Biological reductionism?

A

S- One weakness is that its reductionist
E- This means it is limited down to only one reason on criminal behaviour due to amygdala this is a weakness as we should look at other factors
E- Like environment family life and upbringing
C- However can be positive as can help us narrow down a cure
W- Therefore weakness as to simplistic

17
Q

Evaluation- Biological determinism?

A

S- One weakness is determinism
E- Due to the fact we have no control over amygdala so can’t control behavior
E- However this could be positive as if we believe there is no cure we can test children in primary schools to see if they don’t have fear conditioning meaning interventions put into place to prevent criminals
W- Therefore a limitation

18
Q

Evaluation- Explaining non violent behaviou?

A

S- Another weakness is that it doesn’t explain non violent crimes
E- This theory supports violent crimes but ultimately does not explain the non violent crimes that have no regard for facial expressions e.g shoplifting of fraud
C- However good we can explain violent crimes as they are more severe
W- Therefore explains weakness as it leaves us uncertain on why people commit nonviolent crimes

19
Q

Evaluation- conclusion?

A

Even though there seems to be a lot of evidence to support the role of the amygdala in violent crimes it fails to do so as it does not consider any factors beyond the biological life up bringing
Therefore explanation is said to be incomplete
A more biopsychosocial approach to explain behaviour would provide a more comprehensive understanding of criminal behaviour
