Raine-classic

Question 1

raine aim

Answer 1

if the brain activity of murderers/people pleading not guilty of murder through
diminished responsibility was different to that of non-murderers. They wanted to see if there was a difference in the prefrontal cortex of murderers/people pleading not guilty of murder through diminished responsibility and
normal people

Question 2

raine sample

Answer 2

Their ppts were 41 people charged with murder or manslaughter who pleaded not guilty by reason of insanity (NGRI).
* They were compared to a matched group of people not charged with murder or manslaughter
(matched on age, gender and 6 in each had schizophrenia) (2 females in each group). 6 ppts in both groups were diagnosed with schizophrenia.

Question 3

raine procedure

Answer 3

Each participant carried out a practice test (a visual targeting test)
* 10 minutes later we injected a tracer (FDG) then completed the visual targeting task again
* PET scan was carried out after 32 minutes when the task was finished to see how active the brain had
been in the prefrontal cortex

Question 4

raine results

Answer 4

-Prefrontal Lobe- Lower glucose metabolism in murderers
-Corpus Callosum- Lower activity in murderers
* Amygdala- reduced activity in the LEFT amygdala and more activity in the RIGHT

Question 5

raine conclusion

Answer 5

They concluded that the areas that had abnormal activity were associated with lower self control/increased aggression. They concluded that brains of murderers were significantly different from the
brains of non murderers.
