Multi Store Model Flashcards
(27 cards)
Who created the MSM
Atkinson and Shiffrin
When was the MSM created
1968
Sensory register
All stimulus from environment
Iconic - visual
Echoic - acoustic
Other stores for touch, taste and smell
Econic
Acoustic
Iconic
Visual
What is the duration of the Sensory Register
0.5 seconds
What is the capacity of the sensory register
Limited to one sensation
How much of what goes into the sensory register passes into memory system
Very little
Short term memory store
Info we attend to passes into STM
Encoding of STM
Mainly acoustic
Duration of STM
18-30 seconds
Capacity of STM
Up to 9 (7 +-2)
What study supports the capacity of STM
Miller 1956
Things appear in 7s
Span of STM is between 5-9 items
What study supports the encoding of STM
Baddeley 1966a
Info is encoded acoustically in STM
When people recall things from list, any mistakes are acoustic
What study supports the duaration of STM
Peterson and Peterson 1959
Duration is 18-30seconds
Pps showed Triagram (3 letters) and asked to recall
Between recalling, distraction task to prevent them from rehearsing to go to LTM
80% recall after 3 seconds
10% recall after 18 seconds
How can duration of info in STM be increased
Maintenance rehearsal
Occurs when we repeat material over and over again
What happens if we rehearse info in STM for long enough using maintenance rehearsal
Info will pass into LTM
LTM
Potentially permanent memory store for materials rehearsed for prolonged time
What is the capacity and duration of LTM
Limitless
Encoding is LTM
Semantic
Who found that encoding for LTM is semantic
Baddeley 1966b
What study supports that the duration of LTM info is unlimited
Bahrick 1975
Many pps could recognise names and faces of school class mates 50 years on
By recall and recognition
What has to happen to recall material stored in LTM
Has to be transferred back to STM
Encoding of sensory register
Sense specific
