Working Memory Model Flashcards
What are the 4 features of the working memory?
- STM isn’t unitary consists of seperate components
- Each separate part processes and stores different types of info
- Each component contains different types of memory codes
- Limited storage capacity
Who is the WMM proposed by?
BADDELEY and HITCH
What does the working memory model dispute about the MSM?
STM is a unitary store
What are the 4 main components of STM?
- Central Executive
- Phonological Loop
- Visuo-spatial sketchpad
- Episodic Buffer
What is the central executive?
-The organiser of STM.
-Attends all incoming info, temporarily stores info then decides what pieces of info to send to different components.
-Limited capacity
-Process info from any mode
-Only deal with one type of info at a time —> limited storage capacity
OTHER FUNCTIONS: call up info from LTM, merge info from slave systems and LTM
What is the phonological loop? (PL)
-Auditory info
-Coding is acoustic
-Preserves order in which info arrives
-Active during verbal tasks eg. Learning a phone number until you have remembered it
-Limited capacity
-Sub-divided into: 1.phonological store (words you hear) 2.articulatory loop (repeating words or sounds to keep them in working memory)
What is the Visuo-spatial Sketchpad (VSS)?
-Stores visual and spatial information
-Pattern recognition + perception of movement
-what items look like + physical relationship between them
-Active during visual tasks
-Limited capacity
-Sub-divided into: 1. The visual cache (stored visual data) 2. The inner scribe (records the arrangement of objects in the visual field)
What is the episodic buffer?
-Additional component when BADDELEY updated WMM
-Limited capacity
-Temporary ‘backup’ store
-Integrates and manipulated material from central executive, PL, VSS and LTM and processed info that requires 2 senses at same time
-Makes sense of time-sequencing
-Recall material from LTM and integrate into the components of STM when memory requires it
