Multi Store Model

Question 1

Atkinson and shiffrin

Answer 1

-info flows trough memory
-structural model
-sr stm and ltm
-separate unitary stores
-info flows trough system in a linear way

Question 2

1step SR

Answer 2

-stimulus from env pass into SR
-SR= several stores coding each store is modality specific
-2main echoic coded acoustically nd iconic coded visually
-info in SR duration less than sec
-capacity is high

Question 3

2 step Info passes from SR to STM only if

Answer 3

ATTENTION is paid if not info decays

Question 4

3rd step STM

Answer 4

-limited capacity store of 5-9 items
-info coded acoustically
-duration of info 18-30 sec unless REHEARSED

Question 5

4th If maintenance rehearsal occurs it can

Answer 5

Inc the length of time info is held in stm
If rehearsed enough will pass to ltm

Question 6

5th LTM

Answer 6

-potentially permanent store for info that has been rehearsed for a long time
-capacity unlimited
-info lasts a life time
-codes semantically

Question 7

6th to recall Info

Answer 7

It must be transferred from stm to ltm in a process called retrieval

Question 8

AO3 strength

Answer 8

P-supported by research studies that show STM and LTM are separate unitary stores
E-e.g Baddely found ppt mixed up words sound similar in stm and words that mean similar in ltm
E-study clearly sugg coding in stm is acoustic and ltm is semantic
L- supp stm and ltm are separate stores

Question 9

AO3 limitation

Answer 9

P-too simplistic stating LTM STM unitary stores
E-e.g shallice nd Warrington research into stm conducted on patient kf suffered amnesia
E-found recall poor when read aloud but better could visually see them suggests that there must be diff stores within stm one auditory visual
L- casting doubts on theory of assumption that stm is unitary

Question 10

Another limitation AO3

Answer 10

P-case study is flawed low pop val
E-one p Clive wearing
E- has unsual illness involving brain damage to brain
-therefore diff to gen wider pop may operant diff limiting supp
