ltm memory and msm

Question 1

what are the 3 types of LTM

Answer 1

semantic
episodic
procedural

Question 2

what is the definition of memory

Answer 2

the process of retaining and retrieving information after the original material is no longer present

Question 3

what is semantic LTM

Answer 3

memory for facts and knowledge can be created from episodic LTM

Question 4

what is episodic LTM

Answer 4

memories from personal events

Question 5

what is procedural LTM

Answer 5

action based (muscle memory)

Question 6

what are the 3 types of encoding

Answer 6

visual, acoustic and semantic

Question 7

what are the 3 stages of memory

Answer 7

encoding, storage and retrieval

Question 8

what is encoding

Answer 8

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.

Question 9

what is the capacity of STM

Answer 9

18-30 seconds

Question 10

what is the capacity of LTM

Answer 10

potentially unlimited

Question 11

what is the method used to aid remembering things short term

Answer 11

chunking

Question 12

what are the 3 separate memory stores

Answer 12

sensory register
stm store
ltm store

Question 13

the STM and LTM stores are also known as

Answer 13

unitary stores

Question 14

what does the memory store model describe

Answer 14

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

this happens in a linear way

Question 15

what are the processes that information is transferred and what stores are these between

Answer 15

attention for sensory register to STM

rehearsal for STM to LTM

Question 16

how is information encoded in the STM

Answer 16

mainly acoustic

Question 17

how is information encoded in the LTM

Answer 17

semantically

Question 18

what is the capacity for the sensory register store

Answer 18

very large as it is always receiving information

Question 19

how is information encoded in the sensory register store

Answer 19

it is modality specific eg iconic encoded

and it is in a relatively unprocessed form

Question 20

what is the capacity of the sensory register store

Answer 20

very large

Question 21

what is the duration of the sensory register store

Answer 21

a quarter of a second

Question 22

what is the duration of the STM

Answer 22

18-30 seconds

Question 23

what is the duration of the LTM

Answer 23

potentially unlimited

Question 24

what is the capacity of the LTM

Answer 24

potentially unlimited

Question 25

the sensory register store has lots of sensory registers they are also known as

Answer 25

passive stores as we do not consciously control what goes in

Question 26

what 3 sensory registers

Answer 26

iconic- visual
echoic- auditory
haptic- touch

Question 27

how is information transferred from the sensory register to the STM

Answer 27

through attention as this mechanism allows us to select relevant information and discard the rest

Question 28

what is the capacity of the STM

Answer 28

7 +- 2

Question 29

what are the 6 points to describe the MSM

Answer 29

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

Question 30

how is info forgotten from the sensory register

Answer 30

it decays

Question 31

how is info forgotten from the STM store

Answer 31

displacement or decay

Question 32

how is info forgotten from the LTM store

Answer 32

interference (2 similar memories competing or being asked a question or thinking of something else)
retrieval failure (not having the right cues)
