MEMORY Flashcards
CAPACITY
The amount of information that can be stored in the memory
DURATION
The length of time information can remain in the memory before it becomes unavailable
CODING
The way that info is stored in memory.
Can be stored in the form of visual acoustic pr semantic codes
PETERSON + PETERSON STM DURATION
Showed ppt nonsense trigrams and asked to recall after either 3,6,9,15,19 seconds.
During the break ppts asked to count back in threes from a given number
this was an inteference task to prevent them from repeating letters internally.
BADDELEY CODING IN STM + LTM
Baddeley gave ppts word lists of either acoustically similar, acoustically disimilar, semantically similar, semantically dissimilar.
INDEPENDEN GROUPS DESIGN
ppts asked to recall immediately or after a 20 min task
Ppts struggled with acoustically similar when asked to recall immediately and struggled with semantically similar if recalled after interval
LTM SEMANTIC STM ACOUSTIC
RETROACTIVE INTERFERENCE
When newer information interferes with ability to recall older information
PROACTIVE
When older information interferes with ability to recall newer information
MILLER CAPACITY OF STM
Argued capacity of STM is 7+/-2- millers magic number
Suggested we use chunking to combine individual numbers or letters intolarger more meaningful units.
DESCRIBE THE WWM
BADDELEY AND HITCH
Their model proposed that STM,rather than being a unitary store is an ative processor which contains several different stores
WMM STORES
Central executive- limited capacity, controls slave systems
Phonological loop- holds speech based info. Consists of phonological store and articulatory process
Visuo spatial sketcpad- temporary strorage of visual and spatial info
Episodic buffer- briefly stores info from the other subsytems and integrates it together along with info from LTM.
