- 1Features of the working memorySTM is NOT unitary (but consists of separate components)
- each separate part/component processes and stores different types of info
- each component contains different types of memory codes
- each has a limited storage capacity - 2The WMM (proposed by baddely and Hitch) disputes Atkinson and shiffrin’s claim that STM is a unitary storeWMM is a development of the MSM
(Puts forward a system involving active processing and short term storage of information) - 34 main components of STM- central exclusive
-phonological Loop
- Visio -spatial sketch pad
- episode of buffer - 4What’s the phonological loop made up ofPhonological store
Articulatoria loop - 5Central exclusiveORGANISER OF STM
- attends all incoming info, temporarily stores it and deceives what pieces of info to send to the different components (SLAVE SYSTEMS)
-has a LIMITED CAPACITY
- can process info from any mode (codes info in all sensory forms)
CAN ONLY DEAL WITH ONE TYPE OF INFO AT A TIME - lc - 6Phonological loopDeals with auditory info and preserves the order in which the info arrive
ACTIVE DURING VERBAL TASKS
- LIMITED CAPACITY
———__
1) phonological store - stores words u can hear
2) articulatory loop- allows maintenance rehearsal (capacity of this loop is said to be 2seconds worth of what u can say) - 7Visuospatial sketch padStores/manipulates visual and spatial info
Involved in - pattern recognition and perception of movement
- deals with what items look like and the physical relationship between them eg where a lamp is in a room in relation to the window
ACTIVE DURING VIDUAL TASKS (eg forming an image of something when answering questions about it , mentally counting windows of a house, reading etc)
HAS A LIMITED CAPACITY (about 3,4 objects)
—————-
VISUAL CAHE - stores visual data
INNER SCRIBE - records the arrangement of objects in the visual field - 8Episodic bufferLimited capacity
- ACTS AS A TEMPORARY BACKUP STORE for the ventral exclusive
-responsible for interpreting and manipulating material from the CE, PL, VSS and LtM and processes info that requires two different senses at the same time
ALSO MAKES SENSE IF TIME SEQUENCING (like recordings events that are happening)
- importance is to RECALL MATERIAL FROM LTM AND INTEGRATE IT INTO THE COMPONENTS OF STM WHEN THE WM REQUIRES IT - 9Dual task performance (Way WMM is stidies)Two tasks doen at the sam estime
If p are slower at doing these tasks at the same time than when doing them separately - assumed both tasks compete for the same resources in the brain - 10Baddely et al AIMTest whether STM has separate components as the WMM claims
- 11MethodCondition 1 - p holding a pointer in contact with a. Moving spot of light - asked to describe letter f
2 tracking task and a verbal task (using both vss and Pl) - 12ResultsP found it difficult to track spot of light and de sirve letter f
- much more capable of carrying out the tracking task and the verbal - 13ConclusionTeo Vidal tasks were completed less successfully because of competing for the limited storage of the VSS
Visual and verbal can be done well because they are making use of the separate components(not competing for limited storage in the same component) - 14—
