- Memory Revision
- Working Memory Model - Baddeley and Hitch
- Felt
that STM was not just a unitary store, but a number of stores
- Suggests that there is one store for visual processing and one for processing sounds.
- Central Executive
- Has overall control
- Limited capacity
- Coding - modality free
- Phonological loop
- Deals with auditory information
- Phonological store - stores words heard for a brief period
- Articulatory process - allows sub-vocal repetition of the items in the phonological store
- Episodic Buffer
- Temporary store for information that integrates visual, spatial and verbal information from other stores
- Capacity of 4 chunks of information
- Modality free coding
- Visual-Spatial Sketchpad
- Used for spatial tasks
- Capacity of 3-4 items
- Coded visually
- Felt
that STM was not just a unitary store, but a number of stores
- Multi-Store Model - Shiffrin & Atkinson
- 3 Stores of Memory: Sensory Register, STM and LTM
- Short Term Memory
- Miller - STM capacity of STM in 7 +/- 2 items
- Sensory Register
- Sensory register is made up of 2 stores: Iconic memory (stores visual information) and echoic memory (stores auditory information)
- Short duration but large capacity
- Short Term Memory
- Rehearsal is the process that keeps information in the STM and tranfers it to LTM
- Serial Position Effect
- Glanzer & Cunitz –Tend to remember words from the beginning (primacy effect) and the end (recency effect) of a word list
- Evaluation
- Case of HM -Brain damaged by operation to remove hippocampus to reduce episodes of epilepsy STM remaied normal but could not form new LTMs
- Case of KF - Brain damage led to difficulty dealing with verbal information in STM but normal ability to process visual information
- Evidence of separate LTM stores - Semantic, episodic and procedural
- 3 Stores of Memory: Sensory Register, STM and LTM
- Working Memory Model - Baddeley and Hitch
