Multi-store model of memory

Question 1

Sensory register what it is

Answer 1

Encoded from stimuli through senses

Question 2

Sensory register => capacity, encoding, duration, process

Answer 2

Capacity = largeEncoding = depends on senseDuration = briefProcess = attention

Question 3

STM what it is

Answer 3

Temporary store for information we pay attention to

Question 4

STM => capacity, encoding, duration

Answer 4

C = limitedE = acousticallyD = 18-30 secsP = rehearsal

Question 5

LTM what it is

Answer 5

Potentially permanent memory store for material that has been rehearsed

Question 6

Capacity, encoding, duration of LTM

Answer 6

C = practically unlimitedE = semanticD = unlimited

Question 7

Strength

Answer 7

BaddeleyMix similar sounding words when using STMMix similar meaning words LTMShows separate storesSTM coding is acoustic and semantic is LTM

Question 8

Weakness

Answer 8

Shallice and WarringtonKF STM digits poor when read out loud, but fine when read himselfMSM is not complete (STM can have multiple stores)

Question 9

Question 10

Evidence for duration STM

Answer 10

Peterson and Peterson (1959)Nonsense consonant trigram

Question 11

Evidence for duration, sensory register

Answer 11

Sperling (1963)Flashes ray of letters -> can’t remember after two seconds

Question 12

Evidence for capacity long-term memory

Answer 12
