To investigate if the recall of episodic and semantic memories produced differentblood flow patterns in the brain
Method
6 participants were injected with radioactive gold. Used a repeated measures design with 4 episodic and 4 semantic memory trials. Monitored blood flow using a PET scan
Results
There was different blood flow patterns in 3 of the participants. Semantic memories produced greater blood flow in the posterior cortexes, whilst episodic memories produced greater blood flow in the anterior cortexes
Conclusion
Episodic and semantic memories are localised in different areas of the brain
Strength
Evidence from brain scans is difficult to fake, producing unbiased evidence
Weakness
The data was inconclusive as differences were only seen in half of the participants
