1) Coding, Capacity & Duration Flashcards
1
Q
What is the coding of LTM & STM
A
STM - Acoustic
LTM - Semantic
2
Q
Who found the coding of memory
A
Baddeley
3
Q
What is the span of STM (Capacity)
A
7 +- 2
4
Q
Who found the capacity of memory
A
Miller
5
Q
Who found the duration of STM
A
Peterson and Peterson
6
Q
Findings of the Peterson & Peterson Study
A
STM after 3seconds - 80%
After 18seconds - 3%
7
Q
Who found the duration of LTM
A
Bahrick
8
Q
What is the duration of LTM
A
Recognition Test
AFTER 15yrs - 90%, 48yrs - 70%
Free Recall Test
AFTER 15yrs - 60%, 48yrs - 30%
9
Q
EV of Baddeley - identified 2 memory stores
A
- Later research showed there are a few exceptions to his findings
- but majority is STM is mostly acoustic and LTM is mostly semantic
- Led to development of multi-store-model
10
Q
EV of Miller - may overestimate STM capacity
A
- Cowan reviewed other research
- Concluded stm was 4 plus or minus 1
- suggesting 5 items is more appropriate than 7
11
Q
EV of Bahrick - high external validity
A
- everyday meaningful memories were studied
- wheres when meaningless pictures were remembered they had much lower recall rates (Shepard)
- so Barracks findings reflect a more accurate estimate of the duration of LTM
