Memory Models Flashcards
(14 cards)
Multi Store Model - Created by & Date
- Atkinson and Shiffrin
- 1968
Multi Store Model - What are the 3 parts to it?
- sensory memory
- short term memory
- long term memory
Capacity of STM & LTM
- 7+- bits of information
- infinite
Duration of STM & LTM
- 0-(15-30)s
- Lifetime
Encoding of STM & LTM
- primarily acoustic
- primarily semantic
Retrieval of STM & LTM
- rapid scan of stored info
- linked to sensory modalities
How is information lost out of STM
Decay or Displacement
How is information lost out of LTM
Failure to retrieve or Interference
Different types of rehearsal
- Maintenance rehearsal (STM - STM)
- Elaborative (STM - LTM)
Multi Store Model Evaluation - Evidence for
Glazer and Cunitz
- tested serial position curve
- found 30 second delay and distractor test gets rid of the decency effect and prevents rehearsal
- It dictated the presence of a STM and LTM which are separate which supports model
Multi Store Model Evaluation
- Glanzer and Cunitz criticism
Lab studies are a weakness as they lack ecological validity
- therefore can’t explain how the theory would work in the real world
Multi Store Model - Evaluation
- evidence against
Shallice and Warrington
- the STM was impaired, the LTM functioned normally
- shows that’s the model isn’t limited and it doesn’t go through STM
(Model = reductionist)
Multi Store Model Evaluation
- application
- benefit students
- it can explain that in order to creates LTM’s need to repeats the info again and again
- gives teachers strategies to use in the classroom
Multi Store Model Evaluation
- reductionist
- too simplistic
- e.g mere rehearsal is too simple a process to account for transfer on info from STM to LTM
- ignore factors such as effort and strategy and does not account for types of information
