8
Q

what is encoding

A

creating a chemical trace in the brain
which occurs during presentation of a stimulus
transforms input into a form that can be registered and stored by memory.

14
Q

what does the memory store model describe

A

the process by which information is transferred from one store to another.

this happens in a linear way

15
Q

16
Q

how is information encoded in the STM

A

mainly acoustic

17
Q

how is information encoded in the LTM

A

semantically

18
Q

what is the capacity for the sensory register store

A

very large as it is always receiving information

19
Q

how is information encoded in the sensory register store

A

it is modality specific eg iconic encoded

and it is in a relatively unprocessed form

20
Q

what is the capacity of the sensory register store

A

very large

21
Q

what is the duration of the sensory register store

A

a quarter of a second

22
Q

what is the duration of the STM

A

18-30 seconds

23
Q

what is the duration of the LTM

A

potentially unlimited

24
Q

what is the capacity of the LTM

A

potentially unlimited

25
the sensory register store has lots of sensory registers they are also known as
passive stores as we do not consciously control what goes in
26
what 3 sensory registers
iconic- visual echoic- auditory haptic- touch
27
how is information transferred from the sensory register to the STM
through attention as this mechanism allows us to select relevant information and discard the rest
28
what is the capacity of the STM
7 +- 2
29
what are the 6 points to describe the MSM
structural model with 3 stores (e, c, d) what is/isnt unitary information passes in a linear way MSM explains the transferal on info (attention and rehearsal) the more info is rehearsed the more it can be recalled how info is forgotten at each stage
30
how is info forgotten from the sensory register
it decays
31
how is info forgotten from the STM store
displacement or decay
32
how is info forgotten from the LTM store
interference (2 similar memories competing or being asked a question or thinking of something else) retrieval failure (not having the right cues)
