Describe the working memory model with reference to one relevant study.
when awarding marks.
The command term "describe" requires candidates to give a detailed account of the working memory model with reference to one relevant study.
Components of the working memory model include:
- Central Executive
- Phonological loop: articulatory control system and phonological store
- Visuo-spatial sketchpad
- Episodic buffer
Relevant studies may include, but are not limited to:
- Baddeley and Hitch's (1976) study using the dual task technique
- Baddeley et al.'s (1975) study using the word length effect
- Landry and Bartling's (2011) study using articulatory suppression
- Quinn and McConnel's (1996) study distinguishing visuo-spatial sketchpad and phonological loop
- Conrad and Hull's (1964) study investigating the phonological similarity effect.
- Studies of brain damage to support the theory: Warrington and Shallice's (1974) study of KF.
Although candidates may include a drawing of the model, only the written description of the model should be assessed.
If a candidate describes the working memory model without making reference to a relevant study, up to a maximum of [5] should be awarded.
If a candidate only describes a relevant study without describing the working memory model, up to a maximum of [4] should be awarded.
If a candidate refers to more than one study, credit should be given only for the first study.
