Multi-store model of memory Flashcards
Multi-store model of memory
person
└Atkinson and Shiffrin (1968, 1971)
Parts of the multistore model of memory
Sensory register
└iconic and echoic memory
Short term memory store
Long term memory sort
Sensory register
Coding, capacity and duration
└iconic memory- coded visually └echoic memory- coded acoustically └duration- less than half a second └capacity- high └need to pay attention to pass further into system
Short- term memory
Coding, capacity and duration
└coding- acoustic
└capacity-7+/-2
└duration- 18-30 seconds unless rehearsed
└maintenance rehearsal- keep in STM/move to LTM
Long-term memory
Coding, capacity and duration
└coding- semantic
└capacity- unlimited
└duration- unlimited
└retrieval from LTM to STM- then response (remembering)
Multi-store model of memory
strengths
Supporting evidence └Studies of coding capacity and duration └coding: Baddeley (1966a, 1966b) └capacity: Jacobs (1887) └duration: Petersons (1959)
Multi-store model of memory
Limitations
Summary
- More than one type of STM: Shallice and Warrington (1970)
- Artificial materials
- More than one type of rehearsal: Craik and Watkins (1973)
- More than one type of LTM: Tulving (1985)
Multi-store model of memory
Limitations
More than one type of STM
└Shallice and Warrington (1970)- amnesia patient KF
└must be separate visual auditory
└ he could recall words read himself not read to him
└working memory model does this
Multi-store model of memory
Limitations
Artificial materials
└digits, letters words, consonant syllables (e.g. ZLG) used
└low external validity
Multi-store model of memory
Limitations
More than one type of rehearsal
└MSM says that the more you rehearse information the more likely you are to transfer it into LTM
└Craik and Watkins (1973)
└found rehearsal type matters more than amount of times
└two types of rehearsal
└maintenance rehearsal: maintains it in STM (type describes in MSM)
└elaborative rehearsal: link information to existing knowledge/think about what it means, to transfer it into LTM
└limitation of MSM as research finding cant be explained by it
Multi-store model of memory
Limitations
More than one type of LTM
└research evidence shows it is not a unitary memory store (Tulving 1985)
└episodic, semantic, procedural
