MSM/WMM Flashcards
Coding
The type of format information being stored
Capacity
Amount of information stored
Duration
Length of time information is held for
Short term memory
Capacity - 7+/-2 chunks
Duration - limited 18 secs
Coding - acoustically 
Long term memory
Capacity - unlimited
Duration - lifetime
Coding - semantically
Sensory register
Capacity - very large
Duration - milliseconds
Coding - sense specific
Sensory register research
Sperling - pps shown 3 rows 4 letter each for 0.5 secs immediately recall whole grid or a specific row
Recall 4-5 letters on whole grid only 3 from a row
Show sensory register large capacity
Research for duration of short term memory
Peterson + Peterson - pps shown 3 letter tiagrams then a director task for 3-18 seconds
80% recall after 3 seconds 10% 18 seconds
Show duration has effect on STM
Strength of multi store model
Clive wearing had brain damage from amnesia can’t transfer into to LTM
shows MSM is sequential to transfer info from STM - LTM
Weakness of Multi store model
Contradictory unitary nature of STM
patient KF motorbike accident struggles with STM but LTM fine remember visual images not sound
Shows STM not a single storage system MSM limited explanation
Working memory model
How one aspect of memory organised/functions
Focuses on part of mind active when store info
Central executive
Boss of WMM
Control attention and direct info to slave system
Very little capacity
Phonological loop
Auditory info, has two subcomponents
Articular control process - sub vocal rep of item in phonological store
Phonological store - store acoustic items for short time
Visuo spatial sketch pad
Visual/spatial tasks
Inner scribe - spatial relationship between object
Visual cahe - store visual info - colours
Episodic buffer
Binds and integrate info from all other components send to LTM store
