- The Working Memory Model (MSM)
- Baddeley and Hitch (1974)
- Focused on STM- believed it was not a unitary store (like MSM)
- believed memory is a number of different stores (not just one)
- Central Executive
- direct attention to particular tasks
- Baddeley and Hitch asked participants to do two tasks simultaneously
- Task 1 occupied central executive
- Task 2 involved either articulatory loop or both CE AND AL
- deals with cognitive tasks such as mental arithmetic or problem solving
- Phonological Loop
- encodes speech sounds in WM, typically maintenance rehearsal
- limited capacity
- holds two stores
- Phonological store (inner ear)
- holds words heard for 1-2 seconds
- spoken words enter store directly
- written words must first be converted into an articulatory code before entering
- Articulatory control process (inner voice)
- rehearses information from the phonological store
- Phonological store (inner ear)
- Visuo-spatial Sketch Pad (inner eye)
- stores and process information in a visual or spatial form
- visual: what things look like
- spatial: relationships between things
- limited capacity
- Episodic Buffer
- Receives input from many sources
- temporarily stores and then integrates it in order to construct a mental experience of what is happening right now
- has storage space for both acoustic and visual information
- Receives input from many sources
