WMM Flashcards
What are the four stores in the WMM
Central Executive
Episodic Buffer
Visuospatial sketchpad
Phonological Loop
What is the function of the central executive?
Directs attention to particular tasks.
Assigns a ‘resource’ (the other three stores) to tasks
What is the capacity of the central executive?
Very limited, can’t store data or attend to too many tasks at once.
What is the function of the Episodic Buffer?
Acts as general storage for both visual AND acoustic information.
Integrates info from the 3 other stores, and sends information to the LTM
Maintains a sense of time so things can be remembered in chronological order.
What is the phonological loop made up of
Articulatory store (inner voice)
Phonological store (inner ear)
What is the function of phonological loop?
Deals with auditory information
Preserves the order of info
Articulatory store (inner voice) repeats words that are seen or heard. a.k.a maintenance rehearsal.
What is the function of the visuospatial sketchpad?
Used to plan a spatial task, like getting from one room to another.
visual= what things look like
spatial= the physical relationship between things
AO3
Support of central executive from dual task performance
Hitch and Baddely
Task 1 involved only the central executive (given a statement and asked to say true or false, e.g A comes after B)
Task 2 involved either just the articulatory loop (asked to repeat ‘the’ repeatedly) or the articulatory loop AND the central executive (saying random digits)
Task 1 was slower when task 2 involved both the CE and articulatory loop.
Shows that CE is a part of working memory.
AO3
Evidence from brain-damaged patients
KF forgot more auditory info in STM than visual info.
Also, his auditory problems were limited to verbal material such as letters and words, but not sounds like the phone ringing.
Brain damage only affected phonological loop
Supports idea of separate visual and spatial systems
AO3
Problem with case studies
- Brain injury is traumatic, which may itself change behaviour, and how a person performs on a certain task.
- Case studies are unique and cannot be generalised to the population
