Outline the components of the WMM...

1) Central Executive
2) Episodic Buffer
3) Phonological loop
4) Visuospatial sketchpad


Outline the capabilities of the WMM...

1) Central executive:
Coding - flexible.
Capacity - limited.

2) Phonological loop:
Coding - acoustic.
Duration - ~2 seconds.

3) Visuo-spatial sketchpad:
Coding - visual and spatial.
Capacity - 3-4 items.

4) Episodic buffer:
Coding - flexible.
Capacity - 4 chunks.


Name the two sub-systems of the phonological loop.

1) Phonological store
2) Articulatory Process


What is the function of the visuospatial sketchpad?

Stores information about our surroundings.


What is the function of the phonological store.

Stores the words we hear.


What is the function of the auditory process?

Language production and definition.


Name the two sub-divisions of the visuospatial sketchpad.

1) Visual cache - stores visual data
2) Inner Scribe - arrangement of features in the visual field.


Give an advantage of the WMM.

✔ Neuroscanning evidence form Braver et al - increasing activity in central executive = increasing activity in the prefrontal cortex.

✔ Baddeley's dual task performance study - performance was worse when completing two different tasks simultaneously.

✔ Shallice and Warrington - KF - separate visual and auditory stores.


Give a disadvantage of the WMM.

❌ Reductionist - central executive may have separate stores - raises doubts about the accuracy of WMM.
