Object and Semantic Declarative Memory Systems

Question 1

What is Squire’s theory of the Medial Temporal Lobe Memory System?

Answer 1

Lecture 9, slide 2, 10

Question 2

What studies challenge Squire’s theory?

Answer 2

Lecture 9, slide 4-7

• MTL has a role in non-declarative memory, not just declarative memory
• the MTL is not homogenous in function (hippocampus for spatial memory and perception, perirhinal cortex for object memory and perception)

Question 3

Give some macaque lesion studies that collectively show that object recognition is processed in the perirhinal cortex and not elsewhere. What is wrong with ablation lesions?

Answer 3

Lecture 9, slide 19

-ablation lesions are not selective/specific

Question 4

What effect does set-size have on learning/memory?

Answer 4

Lecture 9, slide 21-22

Question 5

Does the perirhinal cortex have a role in object perception? What studies support this?

Answer 5

Lecture 9, slide 24-25 (macaques), 27-29, 31-35

Question 6

What is perceptual-mnemonic theory?

Answer 6

-perirhinal cortex is important in memory and perceptually discriminating objects.

Question 7

What are domain-specific and process-specific classifications?

Answer 7

Lecture 9, slide 37

Question 8

Does the perirhinal cortex have a role in object familiarity and recency judgments? What studies support this?

Answer 8

Lecture 9, slide 40-41
