Brain Abnormalities Flashcards
(11 cards)
How is the prefrontal cortex related to criminal behavior?
Underactivity or damage to the prefrontal cortex is associated with poor impulse control and decision-making.
What is the biological explanation of criminal behavior in criminology?
It suggests that structural or functional brain abnormalities can contribute to criminal or antisocial behavior.
Which brain area is most often linked to criminal behavior?
The prefrontal cortex, responsible for decision-making, impulse control, and moral reasoning.
What is the link between the prefrontal cortex and crime?
Reduced activity or damage in this area is associated with impulsivity, poor judgment, and lack of empathy—traits often found in offenders.
How is the amygdala related to aggressive or violent behavior?
A smaller or underactive amygdala is linked to reduced fear and emotional response, which may increase the likelihood of violence or psychopathy.
What did Raine’s (1997) study find about murderers pleading NGRI (Not Guilty by Reason of Insanity)?
PET scans showed abnormal activity in the prefrontal cortex and asymmetries in the amygdala and hippocampus.
Who was Fred West?
A British serial killer who, along with his wife Rosemary West, committed numerous murders between the 1960s and 1980s.
What brain abnormality is often associated with violent criminals like Fred West?
Reduced activity or structural damage in the prefrontal cortex, which is responsible for impulse control and decision-making.
Was Fred West diagnosed with a mental illness?
While never formally diagnosed during his lifetime, some speculate he showed signs of antisocial personality disorder or psychopathy.
Was Fred West diagnosed with a mental illness?

What role does the prefrontal cortex play in moral reasoning and criminality?
It helps regulate behavior and control impulses; damage or dysfunction can lead to disinhibition and poor moral judgment.
