The Working Memory Model
Description
Central executive (CE) acts as 'attention', allocates tasks to slave systems, no storage
-
-
Episodic buffer records events (episodes) as they happen, links to LTM.
Evaluation
Strengths
Hitch and Baddeley - ppts. slower when doing dual tasks (CE+CE and articulatory loop). Demonstrates CE.
KF- damage to PL, problems with verbal material (words not sounds) (Shallice and Warrington)
SC- damage to PL, unable to learn word pairs presented out loud (Trojano and Grossi)
-
Limitations
CE doesn't explain anything and more complex than currently represented, evidence from EVR (Eslinger and Damasio).
-
Further Evaluation
Word-length effect - longer words can't be rehearsed (supports phonological loop), articulatory suppression task cancels out word-length effect (supports articulatory process).
Types of LTM
