Paper 1- Memory: Multi Store Model Of Memory

Question 1

Who devised the multi store model?

Answer 1

Atkinson and shiffrin

Question 2

When was the MSM devised?

Answer 2

1968

Question 3

What does the MSM explain ?

Answer 3

How information flows through a series of storage systems

Question 4

What are the tree permanent structure in the memory ?

Answer 4

Sensory register

Short term memory

Long term memory

Question 5

How does easy stage of the memory differ ?

Answer 5

Coding

Capacity

Duration

Question 6

What is coding?

Answer 6

The form in which information is stored

Question 7

What is capacity

Answer 7

How much information can be stored

Question 8

What is duration ?

Answer 8

How long information can be stored for

Question 9

What is the sensory register ?

Answer 9

An automatic response to the reception of sensory information by sense organs

Question 10

What is the echoic store for?

Answer 10

Auditory information

Question 11

What is the iconic store for?

Answer 11

Visual information

Question 12

Why does only some information pass through the sensory register ?

Answer 12

Because only certain amounts of information are Paied attention to

Question 13

Explain the coding research for the sensory register ?

Answer 13

CROWDER 1993- information is only retained in iconic store for milliseconds

In the echo if for two to three seconds

SUPPORTS: idea that we code information in different stores and for different durations of time

Question 14

Explain research for capacity in the sensory register

Answer 14

SPERLING 1960- used a tachistoscope

Flashed 3 x4 array of letters onto decree for 1/20th of a seconds

Sounds were in different tones to indicate which line to recall - High medium and low

Recall was high which supports the capacity of the SR being large

Question 15

Evaluate the capita of the SR

Answer 15

It involves experiments

Experiments only provide an estimate

The lack in mundane realise

Lack in ecological validity

Question 16

What is said to be the duration of the Sensory register ?

Answer 16

To have a limited duration

Each type of store decays at different rates

Other evidence suggests that duration decreases with age

Question 17

Explain the research for the duration of the SR?

Answer 17

WALSH AND THOMPSON 1978-
Found that the iconic store has a duration of 500 milliseconds
Decreases as you get older
Duration of the sensory memories is limited and dependent on age

TREISMAN 1964- played identical auditory information into both ears of ppts with a delay between each
Ppts noticed info was same if delay of 2 seconds or less

Suggests that the echoing store therefore had a duration of 2 seconds

Question 18

Evaluate the duration of the sensory register

Answer 18

Breuer duration of sensory memories due to engrams fading quickly

Biological basis

Evolutionary- only need to focus on perceptual information with an immediate survival value

Question 19

What is the short term memory ?

Answer 19

It receives information from the SR

It’s an active change in memory

Contains information currently being thought about
