neural explanation Flashcards
the neural explanation
neural differences in the brains of offenders and non offenders
evidence involves individuals involved in other APD-reduced emotion and empathy- characteristics of offenders
what psychologist studied the APD brain in brain activity and brain structures?
Raine
what the the aim of raines research
aim-patterns if brain activity with PET scans with murderers abs non nude tees
what was Raines method- DV IV sample controls?
-brain scans of 41 murderers compared with control- PET
med free 2 weeks
results of pre frontal cortex in APD brain- raine
pre- frontal cortex- lower activity linked to lower self control
11%reduction in grey matter volume in PFC
raine other findings for areas of brain metabolism
limbic system- reduced glucose metabolism
amygdala-lack of fear
hippocampus-increased aggression
corpus callosum- problem controlling and expressing emotion
what is the relationship with APD and empathy -mirror neurons
individuals with APD experience empathy sill but more sporadically
what did keysers find about mirror neurons and empathy?
only when offenders asked to expatriate with film depicting pain did they show empathy(mirror neurons activate)
