memory - working memory model Flashcards
who proposed the working memory model?
Baddeley and Hitch (1974)
what is the working memory model?
explanation of how STM is organised and how it functions
what is the central executive?
has a ‘supervisory’ role in monitoring incoming data
focuses and divides out attention by allocated subsystems to tasks
capacity and coding of the central executive
limited capacity
doesn’t store information
what is the phonological loop
salve system for auditory information
coding of the phonological loop
acoustic
what are the subdivisions of the phonological loop?
phonological store - stores words you hear
articulatory process - allows maintenance rehearsal
what is the visual-spatial sketchpad?
slave system for visual and spatial information
coding of visuo-spatial sketchpad
visual and spatial
capacity of visuo-spatial sketchpad
limited - 3 or 4 objects (Baddeley, 200)
what are the subdivisions of the visuo-spatial sketchpad?
added by Logie (1995)
visual cache - stores visual data
inner scribe - records the arrangement of objects in the visual field
what is the episodic buffer?
added by Baddeley (2000)
temporary store of information
integrates information processed by other stores
facilitates communication between central executive and LTM
strength - clinical evidence
KF had poor STM recall for auditory information but could process visual information normally
counterpoint - use of case study
strength - dual-task performance
Baddeley et al (1975) found performance significantly worse when both tasks visual or both tasks verbal
limitation - nature of central executive
Baddeley (2003) recognised it was the most important but least understood
some psychologists believe it may consist of separate subcomponents
