Schmolck study

Question 1

Aim

Answer 1

To investigate the effects of specific brain on semantic memory
Investigate the damage to medial temporal lobe
The determine whether HM’s performance was unique among the patients
U compare brain-damaged to normal

Question 2

Participants

Answer 2

6 participants
3-with developed amnesia, have large medial temporal lobe lesions also damage to anterolateral temporal cortex
2-brain damage hippocampus
1-HM
8 controls

Question 3

How many tests and what are they?

Answer 3

9 tests, 7 of them being semantic test battery and 2 constructed by researchers
48 drawings of alive and objects

Question 4

Procedure

Answer 4

All participants were given tests on three to five separate occasions
48 items could be put into group of 6

Question 5

Results

Answer 5

• Similar pictures: the Controls got all the answers right as did those with hippocampus damage only (H.M. score 98% for living creatures and 100% for objects); MTL+ patients performed worse: 85% for living creatures and 90% for objects
• MTL+ Group: These patients did significantly worse in all the tests (p<0.005)
• Patient H.M.: H.M. did better than the MTL+ patients but slightly worse than the other MTL patients who had damage solely to the hippocampus
• Overall: Controls scored 99%, MTL patients (excluding HM) scored 100% and MTL+ patients scored 78%

Question 6

What is hippocampus responsible for?

Answer 6

Episodic memory

Question 7

What is temporal cortex responsible for?

Answer 7

Semantic memory

Question 8

CON, HM, MTL and MTL+

Answer 8

Controls, HM, people with hippocampus damage, people with widespread

Question 9

What can be explained, declarative or non declarative?

Answer 9

Declarative

Question 10

What’s is semantic and episodic about?

Answer 10

Semantic-knowledge of the world, episodic-past experiences

Question 11

Procedural memory?

Answer 11

Aka typing, walking
