1
Q

What is the aim of Raine’s study?

Q

What is an issue with the sample?

A

The study was only on 41 NGRI criminals and so can’ be applied to others

16
Q

What is a strength of the design in this study?

A

The matched pairs means there are less participant variables making the results about brain activity more valid e.g. we know their age and schizophrenia isn’t effecting their brain activity

17
Q

What is a problem with the matching in this study?

A

They couldn’t be matched on all traits e.g. handedness which might impact on their brain activity in the study

18
Q

Is reliablity a strength or a weakness for Raine?

A

A strength as it is Standardised i.e. the tasks, timings and PET scan so you can easily repeat it to see if it is reliable

19
Q

What is an issue with validity for Raine?

A

Low in ecological validity as the tasks/PET scan might not represent brain activity in real life situations

20
Q

What is a strength of a control in Raine?

A

They were taken off their medication before the study which means we know that their medication wouldn’t be impacting on their brain activity

21
Q

What is a strength of using PET scans?

A

It is Empirical as we can directly measure the glucose metabolism in the brain areas

22
Q

Why has Raine got issues with protection from harm?

A

Yes- it involves an invasive injection
