Peterson (1988) used brain scans to show that Wernickes area was used in listening task and Broca’s in reading task
Tulving showed that the semantic and episodic memories are in different parts of the prefrontal cortex
Case study evidence
Phineas Gage- Metal rod passed through his left eye and out the top of his brain, knocked over but didn’t lose consciousness. Recovered after a few months, but went from kind and reserved to boisterous and rude
