Biological- The Role Of The Amygdala Flashcards
Where is the amygdala located?
Medial temporal lobe
And it’s a part of the lymbic system
What does the amygdala do?
Influences behaviour involved in emotions and motivation
It plays a major role in how we perceive and responds to threats in the environment
Amygdala and aggression what is IED?
Intermission explosive disorder
Amygdala and aggression psychologist?
Coccaro
Amygdala and aggression- Coccaro 2007?
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
Amygdala and aggression- how does coccaro explain criminal behaviour?
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
Fear conditioning- what is this?
Learning to control aggressive behaviour by parents, nursery workers and teachers
A&FC- why can the dysfunction of the amygdala lead to aggressive behaviour?
Person is more aggressive and anti social, more likely to commit crimes, never learned that its not okay as fear conditioning is disrupted
A&FC- how can fear conditioning explain criminal behaviour?
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
A&FC- who is our psychologist?
Gao et al 2010
A&FC- gao et al?
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
Raine et al- what did he find in the amygdala?
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?
Lack of fear not scared of reprocusions
Lack of guilt and remorse so nothing stopping them from committing crimes like murders
Evaluation- supporting evidence?
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
Evaluation- Other brain areas?
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
