Memory Flashcards
1
Q
Research into coding?
A
Baddeley =
- STM –> acoustic.
- LTM –> semantic.
2
Q
Research into duration?
A
STM =
- Peterson and Peterson –> 18 seconds.
LTM =
- Bahrick (yearbooks) –> up to 48 years.
3
Q
Research into capacity?
A
1) . Jacobs =
- 9.3 digits, 7.3 letters.
2) . Miller =
- 7+/- 2 span –> chinking improves capacity.
4
Q
Evaluation of Baddeley?
A
Artificial stimuli =
- word lists had no personal significance.
5
Q
Evaluation of Peterson and Peterson?
A
Meaningless stimuli =
- used consonant syllables –> lacks external validity.
6
Q
Evaluation of Bahrick?
A
Higher external validity =
- Shepard –> meaningless memories = low recall.
7
Q
Evaluation of Miller?
A
Not so many chunks =
- Cowan –> STM = 4 chunks.
8
Q
2 theoretical models of memory?
A
1) . MSM = Atkinson and Shiffrin.
2) . WMM = Baddeley and Hitch.
