Working Memory Model Flashcards
(15 cards)
Who proposed the WMM
Baddeley and Hitch (1979)
What does the WMM propose?
Limited capacity store for retaining information for a brief period while doing mental operations on that information
What does it propose about STM
- STM not a unitary store (CE, PL, VSS)
- STM is an active processor
What is the Central Executive?
- control centre of WMM - controls slave systems
- limited capacity
- coding - any sensory modality
What is the Phonological Loop?
- temporary storage system for verbal info - speech based form
- limited capacity
- codes acoustic info
What is the Visuo-spatial sketchpad?
- temporary storage system for visual and spatial info
- limited capacity
- codes visual and spatial info
What did Baddeley (1986) divide the PL into?
- Phonological store (holds words heard)
- Inner voice (maintenance rehearsal through sub-vocalised repetition)
What is the Word Length Effect, Baddeley (1975)
- immediate memory span better with short words - said faster
What did Logie (1995) divide the VSS into?
- visual cache - stores info about visual items (form and colour)
- inner scribe - stores arrangement of objects for spatial relations
What was added by Baddeley in 2000?
Episodic buffer
What is the episodic buffer?
- temporary store which integrates info from other slave systems
- 4 chunk capacity
- sends info from slave systems to LTM store
Strength - Point
Case Study Evidence KF
Strength - Evidence
KF had brain damage after bike accident and had issues with STM, unable to recall verbal info (PL damaged) but could process visual info like faces (VSS intact)
Limitation - Point
CE and EB components too vague
Limitation - Evidence
Baddeley admitted they were the “least understood” components of WMM. How does it decide which info is relevant? What’s the capacity? Another name for attention?
