Working Model Of Memory Flashcards
Who was the theory created by and when?
Baddeley and Hitch in 1974
Why was the theory created?
-They believed memory was not just one store( unitary) but many stores.
What does this WMM focus on?
Mostly STM not being one unitary store.
What does the theory state the LTM is?
A more passive store that holds previously learned material for use by the STM when needed.
What is the phonological loop and its capacity?
-Deals with acoustic information and preserves word order.
-Has a limited capacity.
-One of the slave systems
What are the two systems in the phonological loop and their job?
-Articulacy loop- voices information you are rehearsing as an inner voice.
-Primary acoustic store-holds memory of sounds.
What is the visuospacial sketchpad and its capacity?
-One of the slave systems.
-Holds visual information.
-Helps with recall of images from the LTM.
-Has a limited capacity.
What are the two systems in the viusospacial sketchpad?
-Visuochache- images and form.
-Inner scribe-spatial information
What is the central executive?
-Manages the 2 slave systems
-No capacity as it doesn’t handle memories.
-Allocates memories to the slave systems.
-It has non-specific modality.
-Controls attention.
What is the episodic buffer?
-Another slave system (added later).
-Deals with specific type of information.
-Has a limited capacity.
-Added later as a more general store as it was unable to explain research findings before.
-Back up storage to other slave systems.
-Connects LTM and STM.
How can the working model of memory be useful for understanding dementia.
-Central executive controls attention and dementia patients struggle to focus on one activity and control their attention.
-can therefore spot the symptoms of dementia and give early treatment
How is the WMM useful for understanding dyslexic?
-People with dyslexia struggle with sounds and hearing words showing their phonological loop is damaged but no anything else such as the visuospaticial sketch pad.
Why might MSM be a better theory than WMM?
-Has a better explanation of long term memory.
-included the sensory register, STM and LTM so is a more complete explanation of memory.
Why might WMM be useful for education?
-can inform revision practices such as not listening to music while reading through notes.
What was Parkins study and how does it conflict WMM?
-conducted a brain scan looking for evidence of the CE but did not find any areas of activity when doing CE activity.
-no empirical evidence of CE, if CE does not exist neither can any of the slave systems so reduces credibility of model.
