raine evaluation

Question 1

ethics
valid consent

Answer 1

as they were murderers who pleaded guilty by reason of insanity , they may not have been mentally competent to provide valid consent

Question 2

ethics
psychological harm

Answer 2

participants may not have fully understood what they were required to do , may have found performance task difficult and this could have possibly lowered the participants self esteem

Question 3

ethics
right to withdraw

Answer 3

may have not realised what was involved in a pet scan , may have found this to be a distressing experience , may not have fully understood their right to withdraw at any time

Question 4

social implications
socially sensitive research

Answer 4

research that has consequences for the larger group of participants who are involved
as people who may have the same brain abnormalities , may believe they may turn into a murderer

Question 5

methodology
quasi experiment
causal conclusions

Answer 5

as the independent variable of this study (ngri or not) was already existing and was not manipulated , means causal conclusions cannot be justified

Question 6

methodology
biology explanation

Answer 6

findings do not show that violent behaviour isnt soley due to biology
raine suggests that psychological, cultural and situational factors play roles too
makes the explanation incomplete

Question 7

methodology
pet scans

Answer 7

allowed researchers to study the brain in a way that was previously not possible , used to rely on post mortems , pet scans allow them to study detailed regions of the brain whilst active

Question 8

procedures
sample

Answer 8

the sample were not typical violent murderers , so the findings do not show that all violent offenders have such brain dysfunctions , can only link to violent offenders who have a diagnosed mental disorder , conclusions are restricted to just violent and not murders and not including violent crimes that aren’t murder
