Multi-store model of memory 1968

Question 1

what does the multi-store memory model propose?

Answer 1

three main stores - sensory memory, long term, short term
info. is passed from store to store in a linear way

Question 2

how is info. encoded in the sensory memory?

Answer 2

one register for each sensory modality (e.g. visual, auditory, haptic)

Question 3

what is the duration of the sensory memory?

Answer 3

less than half a second

Question 4

what is the capacity of the sensory memory?

Answer 4

very large (over 100 million cells in each eye storing info.)

Question 5

how is information retrieved from the sensory memory?

Answer 5

scanning

Question 6

how is information passed to the short term memory from the sensory memory?

Answer 6

info. must be paid attention to.
if it is not payed attention to, it decays

Question 7

how is info. encoded in the STM?

Answer 7

mainly acoustically

Question 8

what is the duration of the STM?

Answer 8

up to 30 seconds (rehearsal extends duration)

Question 9

what is the capacity of the STM?

Answer 9

limited to 7+/-2 items (5-9)
can be overcome by chunking

Question 10

how is information passed from the STM to LTM?

Answer 10

must be elaborately rehearsed, or info. is displaced (new info. takes the place of old info.)

Question 11

how is info. encoded in the LTM?

Answer 11

semantically

Question 12

what is the duration of the LTM?

Answer 12

potentially unlimited

Question 13

what is the capacity of the LTM?

Answer 13

potentially unlimited
