Central Executive

Directs information to all of its slave subsystems
The 'Office' executive

1 of 8

Phonological Loop

Encodes information acoustically
Divided into two subsystems
Phonological store - stores acoustic information
Articulatory process - allows maintenance rehearsal

2 of 8

Visuospatial sketchpad

Encodes information visually/spatially
Divided into two subsystems
Visual cache - stores visual information
Inner scribe - arranges objects spacially

3 of 8

Episodic buffer

Integrates information from all of the slave subsystems and links them to LTM

4 of 8

Strength - case study

Patient 'KF', amnesia following brain injury
Could encode information (in STM) when visual
Failed to encode info in STM when acoustic
Shows that there must be two different ways of encoding info into STM

5 of 8

Strength - research support

Participants given 2 similar tasks (e.g. both visual) performed worse than when given 2 different tasks (one visual and one acoustic). This highlights the differences with memory encoding in STM, as performance decreases when there is competition over one

6 of 8

Weakness - central executive

The central executive lacks clarity and does not have a clear purpose rather than attention
WMM - not fully explained

7 of 8

Weakness - visuospatial sketchpad

The visuospatial sketchpad implies that information is first encoded visually; blind people have great spatial orientation without access to visual info
WMM - overlooks factors that may contribute to memory
