Define coding
The format information is stored in
define capacity
The amount of information a story can hold
define duration
The length of time information is held in a store for
What are the 3 types of memory stores
Sensory register
Short term
Long term
how is short term memory coded
Acoustically
how is long term memory coded
Semantically
how is long term memory coded
Semantically
How is sensory register coded
It is Modality specific (depends on senses)
what is the duration for sensory register
0.5 seconds (hangs on to what we pay attention to)
sensory register has a _____ capacity as it stores ____ sensory information
Large , all
what is the duration of short term memory
18-30 seconds
what is the duration of long term memory
Potentially unlimited
what is the capacity for short term memory
7+ / - 2 (5-9)
what is the capacity of long term memory
Potentially unlimited
who developed the multi store model
Atkinson and shiffrin (pioneers)
recreate the multi store model (draw it)
Must include all arrows
retrieval , maintenance loop , prolonged rehearsal , attention, stimuli from the environment, forgetting x 2 , response+ remembering
STM & LTM & SENSORY REGISTER
what year was the multi store model developed
1968
the two main stores in the sensory register are called….
The iconic memory (visual info)
The echoic memory (auditory info)
Information is transferred from there sensory register to the ?
STM
To prevent information fading in the STM what must take place
Maintenance rehearsal
Information in the STM is coded semantically meaning it turns…
Images or written words in to a verbal code
Give an example of a study that researches coding in both LTM & STM
Baddeleys word lists
describe Baddeleys word list study
4 groups with 4 word lists - acoustically similar & acoustically dissimilar , semantically similar (synonyms) & semantically dissimilar
Independent groups design
what were the results of Baddeleys word list study
Recall immediately- worst performance = acoustically similar
Recall again after 30mins - worst performance = semantically similar (LTM muddled up cannot process info all at once)
