classic evidence: raine buchsbaum lacasse (1997) procedures Flashcards
how was the sample obtained?
using opportunity sampling
how did they study the active brain
using a PET scan
what were all participants given?
an injection of a tracer of FDG
what happens to the tracer after its been injected?
it gets taken up by active areas of the brain making it possible to compare NGRI participants to the control group
30 seconds before the injection what did the participants have to do? and why was this?
they were given a continuous performance task in order to stimulate target areas of the brain in order too see how they functioned
what were the participants allowed to do before receiving injection?
a practice run of the continuous performance task
why did the participants start the continuous performance task 30 seconds before getting the injection?
so the initial task novelty wouldn’t be FDG labelled.
what happened after the FDG injection and how long after?
32 minutes after the FDG injection a PET scan was done of each pp
what was recorded during the PET scan? how did they do this? why did they include such detail of these processes in the article?
10 horizontal slices of the brain were recorded using the cortical pee and box techniques, these processes were in heavy detail in the article so the study could be replicated
