Working Memory Model
Fichas del conjunto (12)
- 1The working memory model by Baddeley and Hitch (1974) claim STM is composed of 4 components...what are they?
- 2What is the phonological store and where is it found? (Baddeley and Hitch (1974)Found in phonological loop. It holds info in speech based form for 1-2 secs. Spoken words enter the store directly but written words must first be converted into articulatory (spoken) code before they can enter the store.
(Baddeley and Hitch (1974) - 3What is the phonological loop and what is it comprised of? (Baddeley and Hitch (1974)The phonological loop deals with spoken and written material.
It has two parts - the phonological store and the articulatory control process
(Baddeley and Hitch (1974) - 4What is the articulatory control process and where is it found? (Baddeley and Hitch (1974)The articulatory control process acts like an inner voice rehearsing info from the phonological store. It circulates info round like a tape loop. Found in the phonological loop (Baddeley and Hitch (1974)
- 5What is the visuo-spatial sketch pad? (Baddeley and Hitch (1974)- Deals with visual and spatial information.
- Obtained from either immediate environment or retrieved from LTM. - 6What is the central executive? (Baddeley and Hitch (1974)The CE is the key component which controls attentional processes rather than acting as a memory store.
It gives priority to particular activities.
Responsible for integrating info from PL and VSSP and drawing on info held in LTM,
The CE has a limited capacity.
- 7What is the episodic buffer? Baddeley 2000Added later, previously no component in WMM could combine several kinds of info
-Limited capacity
- general store which integrates info from PL, VSSP and LTM into a unitary multi dimensional representation - 8Supporting evidence for working memory model by Baddeley and hitch (1974)? (interference task)Interference tasks - Ppts were asked to do two tasks simultaneously which used the same system. e.g saying 'the,the,the' whilst silently reading something. Both tasks used PL which has a limited capacity and therefore cannot cope with both tasks.
Supports WM idea of stores - 9Supporting evidence for working memory model by Baddeley and hitch (1974)? (Dual task)Robbins et al 1996 investigated effects of secondary tasks on quality of chess-move selection in stronger and weaker players.
Found that selecting chess moves involved CE and VSSP and the effects of the secondary tasks were the same on both players indicating they both use WM the same way. - 10Supporting evidence for working memory model by Baddeley and hitch (1974)? (case study)K.F (Shallice & Warrington 1970) performed very poorly on verbal digit span task, yet did very well on visual memory task. Which shows that there are separate STM components for visual VSSP and verbal info (PL)
- 11What are the strengths of the Working Memory Model?+ Supporting evidence - interference and dual tasks
+ Explain some deficits in MSM like why performance can vary across various tasks
+ Applies to real life tasks
+ Concerned with active processing and transient storage - 12What are the weaknesses of the Working Memory Model?- Role of CE not clear
- Capacity of CE difficult to measure
- Not a complete model of memory ignores sensory and LTM
-Lacks detail on how episodic buffer interacts with other components
- Liberman (1980) argues blind people have a brilliant VSSP despite never having visual info
