memory - multi store model

Question 1

intro to essays - AO1

Answer 1

• Atkinson and shiffrin suggest MSM = structural model
• suggests STM and LTM = separate unitary stores
• info flows through system in linear way

Question 2

multi-store model - AO1

Answer 2

• stimulus from environment e.g. sound of someones name passes into sensory register

sensory register
- coding = modality specific
- 2 main stores = echoic (codes acoustically) and iconic (codes visually)
- unlimited capacity
- duration = less than 0.5 seconds

• if attention is paid to info
• passes into STM
• info decays if attention not paid
• STM = acoustically codes
• capacity 5-9 items
• duration 18-30 secs unless rehearsed
• maintenance rehearsal increases time info is held in STM
• prolonged rehearsal = info passes into LTM
• LTM codes semantically
• duration = potentially life time
• unlimited capacity
• for info to be remembered/retrieved
• info transferred from LTM to STM

Question 3

research to support - AO3
research studies by baddeley

Answer 3

P - research to support
- studies by baddeley

E - found that ppts mixed up acoustically similar words when using STM
- semantically similar words when using LTM

E - suggests STM codes acoustically
- LTM codes semantically

L - supports MSM
- STM/LTM = separate unitary stores

Question 4

research to support - AO3
clive wearing
DISCUSSION

Answer 4

P - research to support
- Clive wearing

E - suffers from amnesia
- cannot transfer info from STM to LTM

E - when wife leaves room and re-enters
- greets her asif not seen her in years

L - supports MSM
- separate stores STM/LTM
- info flows through in linear way

DISCUSSION
- low population validity
- case study
- one person with unusual illness
- other peoples memory may operate differently
- limits RTS

Question 5

weakness - AO3
too simplistic
shallice and warrington/patient KF

Answer 5

P - weakness
- too simplistic

E - shallice and warrington
- conducted research on patient KF
- suffered with amnesia

E - found that KF’s memory = better when digits read himself
- compared to when read aloud

L - suggests there are different stores in STM
- one to process visual
- one to process auditory
- casts doubt on theories that STM = unitary store
