Methodology of Raine et al

Question 1

Sample Selection

Answer 1

The researchers recruited a sample of 41 individuals who had been convicted of murder. These individuals were compared with a control group of 41 non-murderers matched for age, sex, and other relevant demographic variables

Question 2

Brain Imaging

Answer 2

(MRI) scans were used to examine the brains of participants. MRI technology allows for detailed imaging of brain structures, enabling researchers to identify any abnormalities.

Question 3

Brain Functioning Measures

Answer 3

the researchers employed Positron Emission Tomography (PET) scans to assess brain functioning. PET scans can measure brain activity by detecting the distribution of a radioactive tracer injected into the bloodstream.

Question 4

Psychological Assessment

Answer 4

Participants underwent thorough psychological assessments to evaluate factors such as psychiatric disorders, substance abuse history, and personality traits.

Question 5

Statistical Analysis

Answer 5

The data collected from brain imaging, psychological assessments, and other measures were subjected to rigorous statistical analysis to identify any significant differences between the murderer and non-murderer groups.

Question 6

Conclusion

Answer 6

Overall, Raine et al.’s study employed a multi-faceted approach to investigate potential neurological differences between murderers and non-murderers, combining advanced imaging techniques with psychological assessment tools.
