Multistore Model Flashcards
Who proposed this model and when was it proposed?
Atkinson and Shiffrin - 1968
What is the sensory memory
Brings attention to information and this information is stores briefly (less than a second) in the sensory memory and can only hold one sensation.
Characteristics of the short term memory
- encoding = acoustic
- capacity = 7+/-2 bits of information
- duration = 18-30 seconds without rehearsal
Characteristics of the long term memory
- encoding = semantic (meaning )
- capacity = unlimited
- duration = a lifetime
Information can be BLANK from the LTM and brough back into the BLANK
Retrieved / short term memory
Information can be BLANK from the STM and brought into the BLANK BLANK
Recalled / conscious mind
What is the rehearsal loop
- stores up to 9 items of information
- the more often information is looped through the short term memory, the more securely it is rehearsed.
AO3 - reductionist
Multi-store model is reductionist as is oversimplifies and ignores other factors like different types of STM and LTM
AO3 - Miller (1957)
- Found that STM has a capacity of 7 items of information comfortably, called chunks.
- supports MSM, improves reliability
AO3 - Baddeley (1966)
- we tend to mix up words that sound similar when we are using our STM
- we mix up words with similar meanings when we’re using our LTM
- supports MSM as we encode acoustically with STM and semantically with LTM
- improves validity
AO3 - Campitelli (2015)
- argues that the STM is the part of the LTM we are currently focusing on and that they aren’t separate stores
- against MSM
AO3 - Peterson (1959)
- the duration of the STM is between 18 and 30 seconds but can be extended by the maintenance of rehearsal
- supports STM duration theory proposed
- improved validity
AO3 - Bahrick (1975)
- many participants could remember the faces and names of school peers 50 years later
- supports the durations of the LTM being a lifetime
- improves validity
AO3 Clive Wearing
- no short term memory but could remember long term memories
- supports the idea of separate stores
- shows application to real life and improves validity
