Resource summary

Evaluation of Raine's 1997 study
  1. GENERALISABILITY
    1. Largest sample size for PET scanning = enough for useful comparison
      1. Therefore better generalisation to murderers pleading guilty
      2. HOWEVER...
        1. At no time were the murderers circumstances taken into account
          1. For example, murder may have been committed in act of defence
      3. RELIABILITY
        1. Scientic method- likely to have reliable findings
          1. Can be replicated
            1. Replicating the study with different groups of participants would help give strength to results
          2. APPLICATION
            1. PET scans can be used in defence in a court of law
              1. In a situation where an individual is pleading guilty for reasons of insanity
            2. VALIDITY
              1. The results given are not very precise, in terms of areas of activity and how active
                1. They do not tell you what areas of the brain are actually doing
                2. They can say which parts are active at any time
                  1. But not why, and this is an issue for the validity of the results
                    1. NEEDS AN EXPLANATION
                3. ETHICS
                  1. PROTECTION OF PARTICIPANTS
                    1. Individuals may have become stressed by the procedure of the PET scan
                  2. OBJECTIVITY
                    1. PET scanning is an objective technique
                      1. Results can be interpreted by more than one researcher
