**L5 - The Working Memory Model Flashcards
what did BADDELEY and HITCH say about the MSM?
BADDELEY and HITCH QUESTIONED THE IDEA promoted by the MSM that people only have ONE TYPE OF STM.
They also argued that STM is FAR MORE COMPLEX than simply being a TEMPORARY STORE FOR INFORMATION before its transferred to LTM.
what was their new concept for STM? (BADDELEY AND HITCH)
They instead saw STM as an ACTIVE STORE holding SEVERAL PIECES OF INFORMATION while they are BEING WORKED ON, that is why they referred to their model as the WORKING MEMORY MODEL (WMM).
They argued that LTM IS THE PASSIVE STORE that only holds PREVIOUSLY LEARNED MATERIAL to be USED BY STM WHEN NEEDED.
The WORKING MEMORY MODEL consists of 4 DIFFERENT ELEMENTS: the CENTRAL EXECUTIVE and the 3 SLAVE SYSTEMS
what is the CENTRAL EXECUTIVE?
The CENTRAL EXECUTIVE DRIVES the whole WORKING MEMORY SYSTEM and ALLOCATES DATA TO OTHER COMPONENTS, known as SLAVE SYSTEMS.
It also deals with COGNITIVE TASKS such as MENTAL ARITHMETIC, REASONING and PROBLEM SOLVING.
ATTENTIONAL CAPACITY and the CENTRAL EXECUTIVE
Individuals have a LIMITED ATTENTIONAL CAPACITY, tasks that are AUTOMATED make LESS ATTENTIONAL DEMANDS on the CENTRAL EXECUTIVE and so leave us FREE TO PERFORM OTHER TASKS
how can an experienced driver multitask - central executive
a person who has been DRIVING FOR 10 YEARS will find that driving has become an AUTOMATED TASK that does not make as many ATTENTIONAL DEMANDS as it did when they were LEARNING TO DRIVE, and so they CAN NOW LISTEN TO THE RADIO or TALK TO PASSENGERS MUCH MORE EASILY THAN A LEARNER DRIVER CAN
what is the PHONOLOGICAL LOOP? And what are its TWO SUBCOMPONENTS
The PHONOLOGICAL LOOP is the COMPONENT OF WORKING MEMORY that DEALS WITH SPOKEN AND WRITTEN MATERIAL. It has TWO SUBCOMPONENTS:
1) PHONOLOGICAL STORE
2) ARTICULATORY LOOP
what is the PHONOLOGICAL STORE (SUBCOMPONENT)
The PHONOLOGICAL STORE is sometimes referred to as the INNER EAR. It is linked to SPEECH PERCEPTION and holds INFORMATION IN SPEECH BASED FORM for 1-2 SECONDS
what is the ARTICULATORY LOOP? (SUBCOMPONENT)
The ARTICULATORY LOOP is sometimes referred to as the INNER VOICE. It is linked to SPEECH PRODUCTION and is USED TO REHEARSE and STORE VERBAL INFORMATION from the PHONOLOGICAL STORE.
This ALLOWS FOR MAINTENANCE REHEARSAL
What is the VISUO SPATIAL SKETCHPAD? And what are its two SUBCOMPONENTS
The VISUO SPATIAL SKETCHPAD STORES and PROCESSES INFORMATION in a VISUAL OR SPATIAL FORM.
It is USED FOR NAVIGATION. It is sometimes referred to as THE INNER EYE.
It has two SUBCOMPONENTS:
1) VISUAL CACHE
2) INNER SCRIBE
what is the VISUAL CACHE?
The VISUAL CACHE STORES VISUAL MATERIAL about FORM and COLOUR
what is the INNER SCRIBE?
The INNER SCRIBE HANDLES SPATIAL RELATIONSHIPS
what is the EPISODIC BUFFER?
BADDELEY added ANOTHER COMPONENT called the EPISODIC BUFFER because he realised that the model NEEDED A GENERAL STORAGE COMPONENT to OPERATE PROPERLY.
This is because the SLAVE SYSTEMS ONLY DEAL WITH PROCESSING and TEMPORARY STORAGE of SPECIFIC TYPES OF INFORMATION, and the CENTRAL EXECUTIVE has NO STORAGE CAPACITY AT ALL.
EPISODIC BUFFER IN THE CONTEXT OF WMM
The EPISODIC BUFFER is a LIMITED CAPACITY STORE, INTEGRATING INFORMATION from the CENTRAL EXECUTIVE, the PHONOLOGICAL LOOP and the VISUO SPATIAL SKETCHPAD, as well as from LTM
