Procedure

• what was the sampling technique?

  opportunity sampling - participants who were readily available and willing to take part in research
• what are the 3 pieces of equipment used in the study?

  FDG injection

  PET scans

  continuous performance task (CPT)
• what is a PET scan?

  brain imaging technique
• what does a PET scan produce?

  3D image of brain
• what does a PET scan demonstrate?

  activity & structure of the brain
• what is the FDG injection?

  fluorodeoxyglucose injection
• what was the point of the FDG injection?

  its a tracer to highlight the active parts of the brain
• what did the FDG allow researchers to do?

  compare the brains of murderers and non-murderers
• what is CPT?

  continuous performance task
• what is the point of CPT?

  to activate the target area of the brain so researchers can see how different areas function
• participants given time to practice CPT before FDG
• what is the order of the steps of the procedure?

  the CPT

  the FDG

  PET scan
• how soon before the FDG was the CPT started?

  30 seconds before so novelty of the task wouldn't make the target area FDG labelled
• how long after the FDG were PET scans taken?

  32 minutes
• how many horizontal slides were recorded and using what method?

  10 horizontal slide using cortical box & peel technique
• what does the original report provide?

  precise details of scanning techniques so the study can be replicated
