The Working Memory Model Flashcards
Central executive…
‘The Boss’
Monitors incoming data, makes decisions and allocates slave systems to tasks
Very limited storage capacity
Episodic buffer…
Added by Baddeley 2000
Integrates visual, spatial and verbal information processed by other stores
Maintains a sense of sequencing recording of events that are happening
Links WM with LTM
Visual spatial sketch pad…
Stores visual and spatial information
Baddeley says capacity is about 3-4 objects
Logie 1995 subdivided into two parts visual cache and inner scribe
Visual cache
Stores visual data
Inner scribe
Records arrangement of objects in visual field
Phonological loop…
Assesses LTM to store/retrieve info about long sounds and allows development of vocabulary
Auditory info divided into articulatory control and phonological store
Articulatory control
Allows maintenance rehearsal
Phonological store
Stores what you hear
Shallice and Wallington 1970 evaluation
Patient KF- brain damage
Poor STM ability for verbal but could process visual normally
Suggested PL damaged but other areas intact
Dual task performance
Supports idea for visual spatial sketch pad
Baddeley 1993- all participants do first task of tracking a light ( using VSS). 1st group also describe angles in the letter F (another visual task) and the 2nd group do a verbal task. Performance was much better in the second group as they were using separate slave systems
Rehearsal evaluation
Less emphasis on rehearsal which can help to explain why some things end up in our LTM when we haven’t rehearsed them suggesting other processes have an impact
Central executive evaluation
It is too simplistic and vague. Their model doesn’t explain exactly what it is, apart from being involved in attention and it is difficult to design tasks to test it.
STM evaluation
Only focuses on STM, not how information is transferred to LTM
