multi store model

Question 1

Multi store model
ATKINSON & SHIFFRIN (1968)

Answer 1

Explanation of memory that sees information flowing through a series of storage systems in a fixed sequence.

Question 2

Sensory register

Answer 2

Duration - half a second
Capacity - High
Encoding - sensory information (eg sound)

Question 3

Short term memory (STM)

Answer 3

Duration - 18 to 30 seconds
Capacity - 5 to 9 items
Encoding - Acoustic

Question 4

long-term memory (LTM)

Answer 4

Duration - Years perchance lifetime
Capacity - Unlimited
Encoding - Semantically

Question 5

Strength

Answer 5

Baddeley (1966a,b) - we tend to mix up words that sound similar when using STM, but tend to mix up words that have similar meanings when use LTM - STM is acoustic and LTM is semantic encoding - shows that both memory stores are separate and independent. However, not all psychologists accept that the stores are separate
Clive Wearing - unable to make new memories (amnesia), MSM suggests they fails to rehearse information from STM to LTM

Question 6

Weakness

Answer 6

Shallice & Warrington (1970) - KF’s had poor STM when reading digits out loud to him but his recall was far better when he was able to read the digits himself - MSM not a a complete explanation of memory was there must be separate stores for visual and auditory information

Question 7

RW application

Answer 7

improving memory - ‘chunking’ used to remember numbers or letters in groups of three as it takes up item spaces in the STM enabling you to store more information
