describe the methodology of Raine et el

Answer 1

Raine et al.’s study was a quasi-experiment, meaning the independent variable (murderers vs. non-murderers) naturally occurred. The study used a matched pairs design, matching participants by age and sex. The experimental group had 41 murderers who pleaded NGRI and were off medication for two weeks. The control group had 41 non-murderers, with 6 having schizophrenia to match those in the experimental group. All participants were checked for mental impairments.
