Capacity, duration + coding Flashcards
1
Q
coding
A
- SR
- STM
- LTM
2
Q
coding - SR
A
coding = modality specific, each sensory store codes differently e.g. iconic for visual info
3
Q
coding - STM
A
STM = coded acoustically
4
Q
coding - LTM
A
coded semantically
5
Q
evaluation of coding
A
+ study is lab experiment = easy to replicate + variables closely controlled, reliability can be assessed
- findings have low ecological validity
= material which parts needed to recall was artificial unlike types of info people need to recall in their everyday life + lab setting
6
Q
capacity - SR + LTM
A
unlimited
7
Q
capacity - STM
A
7 ± 2
8
Q
evaluation of capacity
A
+ research was the first to acknowledge that STM capacity gradually improves w/age
- study was conducted a long time agp, may not have been done to the same scientifically rigorous standard as research today
= lacks temporal validity
9
Q
duration - SR
A
250 milliseconds
