- Memory
- Multi-store model (Atkinson & Schiffron 1968)
- Short term memory
- Attention
- Limited duration & Capacity
- Maintenance rehearsal
- Sensory memory
- Brief Duration
- Attention
- Long term memory
- Maintenance rehearsal
- Unlimited duration & capacity
- +
- Evidence for separate stores (Glanzer & Cunitz 1966 or Sperling 1960)
- Has caused much further research
- Includes details of structure
- Evidence for encoding, duration and capacity
- Includes details of structure
- Has caused much further research
- Evidence for separate stores (Glanzer & Cunitz 1966 or Sperling 1960)
- -
- Oversimplified
- STM is not unitary store (KF 1970)
- LTM not unitary -semantic, spisodic memories
- More than maintenance needed-Craik & Lockhart 1972)
- LTM not unitary -semantic, spisodic memories
- STM is not unitary store (KF 1970)
- Oversimplified
- Validity
- participants often psychology students-guess experiment
- lab experiments- demand characteristic, well controlled
- participants often psychology students-guess experiment
- Short term memory
- Working memory model (Baddeley & Hitch 1974)
- Vislo-spacial sketch pad
- Visual cached & inner scribe, deals with location & movement
- Phonological Loop
- Phonological store & articulation process-maintenance rehearsal, deal with auditory and speech based info
- Episodic Buffer
- General store & integrates info from other stores (+LTM)
- Central executive
- Resource allocation, small capacity
- +
- More detailed, shows sub systems in STM, also process more than structure in STM
- MRI shows CE more active in 2 tasks (Bunge et al 200)
- Explains KF, phonological loops damaged but otherwise no trouble
- Episodic buffer compare recall of related words better than unrelated (Baddeley et al 1987)
- Explains KF, phonological loops damaged but otherwise no trouble
- MRI shows CE more active in 2 tasks (Bunge et al 200)
- More detailed, shows sub systems in STM, also process more than structure in STM
- -
- Central executive explains nothing e.g. unknown capacity- likely several components
- Focuses only on STM unlike MSM
- Experiments questioned-Paulesdo study small sample size, brain damamged individuals have no before/after rsults
- Focuses only on STM unlike MSM
- Central executive explains nothing e.g. unknown capacity- likely several components
- Explains being able to do two different tasks at same time but not similar tasks
- Validity
- Same as MSM
- Vislo-spacial sketch pad
- Multi-store model (Atkinson & Schiffron 1968)
