Flashcards in Contemporary study - Schmolck et al. (2002) Deck (17):
1

BACKGROUND:
Previous research assumed that...

the medial temporal lobe has a part to play in semantic memories and the hippocampus is more responsible for episodic memories

2

BACKGROUND:
Schmolck's study investigates...

those with amnesia in order to determine which parts of the brain are mostly responsible for semantic memories

3

BACKGROUND:
What is anterograde amnesia?

loss of the ability to create new memories after the event that caused the amnesia (memories from before the amnesia stay in tact)

4

BACKGROUND:
What is retrograde amnesia?

inability to recall events that occurred before the development of the amnesia

5

BACKGROUND:
What are semantic tests?

testing semantic (factual) knowledge

6

BACKGROUND:
What is brain scanning?

producing images of the brain

7

BACKGROUND:
What is bilateral?

both sides of the brain (both left and right hemispheres)

8

BACKGROUND:
What is anterolateral?

to the front and side of the brain

9

BACKGROUND:
What is lateral?

the side of the brain

10

BACKGROUND:
What is medial?

middle of the brain

11

AIMS

1. To investigate the effects of brain damage on semantic memory

2. To test the relationship between semantic test scores and temporal lobe damage

3. To determine if HM was unique in the way his brain damage affected his memory

12

METHOD:
Research method

lab experiment, MRI and CT brain scanning

13

METHOD:
Participant design

matched pairs

14

METHOD:
Sampling method

opportunity

15

METHOD:
Independent variable

type of brain damage

16

METHOD:
Dependent variable

number of correct responses (semantic memory)

17

METHOD:
Sample

6 Ps with amnesia and various brain damage

> 2 patients with damage to only the hippocampus in the temporal lobe (least damage)

> 3 patients with damage to the medial temporal lobe and anterolateral temporal lobe (most damage)

> HM - damage to his medial and lateral temporal lobe

Control group
> 8 Ps
> Matched to brain damaged patients by age, sex & education (factors that could affect ability)
