4 - physical aggressiveness
5 - Reckless disregard for the safety of self or others.

Boldness – a need to always seek social dominance and risk-taking.
Meanness – lack of remorse, insensitive towards others, and disregard for others.
What is the primary difference between antisocial personality disorder and psychopathy?
Must have evidence of the onset of conduct disorder before age 15
What is considered the gold standard in forensic psychology for assessing psychopathy?
Robert Hare’s psychopathy checklist - revised (PCL-R)
What four neurological areas appear to be linked to psychopathic behaviour?
1 - Amygdala.
2 - ventromedial prefrontal cortex.
3 - dorsolateral prefrontal cortex.
4 - orbitofrontal cortex.
What does dysfunction in the amygdala do?
Higher levels of aggression, violence, and Psychopathic traits.
What does dysfunction in the orbitofrontal cortex do?
lowers the ability to process others’ emotions end guide social behaviour.
what does dysfunction in the dorsolateral prefrontal cortex do?
Diminishes self-regulation and heightens impulsivity.
what does dysfunction in the ventromedial prefrontal cortex do?
lowers the likelihood of reward and Punishment to guide Behavior.
what is cortical stimulation?
Stimulates the membrane above the brain (dura) with electrodes, Stimulates this area to stimulate the brain.
What is transcranial direct-current stimulation?
Brain stimulation of the brain surface such as on the prefrontal cortex via electrodes.
what is deep brain stimulation?
invasive brain stimulation technique to target inaccessible brain regions such as the amygdala.
what system does deep brain stimulation use?
A three-component system.
