6.1.1 Amygdala & Aggression Flashcards
What is the amygdala responsible for?
- perception of emotions
- emotional remeberance
What part of the brain is the amygdala from + it’s role?
> works in Limbic system to send physiological fight/flight to PFC
Due to being part of the ‘primitive brain’, what else is the amygdala responsible for?
Our basic urges:
- appetite
- sleep
- sex
- drive
- fear
Where does the amygdala take information from and what does it do with it?
- It takes info from the thalamus and interprets it as a threat or not, producing fear, aggression, and fight or flight.
What is the relationship between the amygdala and the frontal lobe?
> If PFC = healthy, then willpower can resist amygdala’s urges of fear/ aggression
How does the prefrontal cortex aid the amygdala?
> Decides best how to respond to a situation which amygdala stores as a memory
Then if situation reoccurs, response produced w/o logical though from PFC needed
How might the prefrontal cortex regulating the amygdala explain criminality?
> May lead to incorrect emotional responses + inability to understand emotions, explaining lack of remorse criminals feel eg psychopathic offenders + violent crimes ie murder
What are the gender difference in the amygdala?
- None involving amygdala functioning + criminality, but Shirtcliff et al (2009) found girls = more empathetic so diffs in emotionality may come from amygdala, suggesting women have more remorse when committing crimes/ decr violent crimes committed by women.
EACH-Evidence
1.Whitman (brain injury eval)
2.P-Blair (2007) supports
E-Found psychopaths have reduced response to threatening stimuli + anticipation of punishment
E-S, explains that bc amygdala responsible for fight/flight + rational thought w its relationship to PFC,if its damaged then may lead to inability to sense danger + inability to have appropriate responses. Without this may lead to decr remorse + incr recidivism, often found in psychopathic offenders
EACH-Application
A-P- Yes
E-Amygdalotomies- the removal of the amygdala- evidenced to reduce aggression due to the removal of part of the ‘primitve brain’ such as sex drive and aggression drive which can lead to crimes
E-S, treatment to reduce aggression so can rehabilitate criminals/ prevent criminality
EACH-Criticisms
1.P-Deterministic
E-Suggests there’s no free will in criminality due to response being elicited by amygdala is out of our control
E-W, suggesting int factors determine criminality, inconsistent w society’s idea of responsibility + self-control
2.P- SLT as alternative
E-Explains aggression can be learnt through observation of RMs also being aggressive, can lead to crim behav
E-W, shows other explanations + a holistic approach needed to understand criminality better
EACH-How good is the research
H- Same as brain injury
