Is procedural memory declarative?

Non-declarative, as it is based on performance, not recall, so can’t easily be put into words.

Q

How does the case study of Henry Molaison support the theory of different types of LTM?

A

After having his hippocampus removed during an operation, he knew how to walk (procedural), could explain what a dog was (semantic), but could not recall stroking a dog 30 minutes ago (episodic). This shows that there are different types of LTM in different parts of the brain.

18
Q

How does the case study of Clive Wearing support the theory of different types of LTM?

A

He was a world class musician who had a viral infection which damaged his hippocampus. He could still play piano (procedural), and understand the meanings of words (semantic), but he couldn’t remember his musical education or the last time he saw his wife (episodic). This shows that there are different types of LTM in different parts of the brain.
