The Multi Store Model

Question 1

STM

Answer 1

The information will decay quickly if not rehearsed, it will also disappear if new information comes along, this is because STM has a limited capacity

Question 2

LTM

Answer 2

Initially rehearsal maintains information in STM but the more it is rehearsed the more lasting the memory will be, so you have to rehearse the information in order to remember it

Question 3

Spelling - the sensory store support

Answer 3

Pops saw a grid of digits and letters for a blink of an eye (50 milliseconds) they were either asked to write down all the 12 items, or they were told they would hear a tone after exposure and to write down that row, when asked to recall the whole thing their recall was poorer (5 items recalled about 42%) than one row (3 items recalled 75%) this shows information decays quickly in

Question 4

The serial position effect, Glanzer and Cuniz

Answer 4

List of 20 words, presented one at a time, asked to recall all they could remember, tended to remember words at the beginning (primary effect) and the end of the list (recency effect) the first words are rehearsed and placed into LTM, the last words are still in the STM

Question 5

Areas of the brain associated with STM and LTM

Answer 5

Brain scans, take images of active parts of the brain when a person is doing a specific task, prefrontal cortex is active in STM tasks and the hippocampus with LTM tasks

Question 6

Case study’s

Answer 6

HM hippocampus removed, his personality and intellect remained intact but couldn’t form any new LTM, this suggests that the hippocampus may function as a memory gateway which new memory’s must pass through before entering permanent storage

Question 7

Provides an account of memory

Answer 7

In terms of both structure and progress

Question 8

MSM has a clear prediction about memory

Answer 8

So I can easily be tested

Question 9

It oversimplifies memory’s

Answer 9

Structures and progresses

Question 10

KF

Answer 10

Had brain damage so he had difficulty dealing with verbal information in STM but a normal ability to progress visual information, this suggests that STM is not a single store

Question 11

Four LTM memory stores

Answer 11

Semantic- the world, including words
Episodic - what you did yesterday etc
Procedural - how to ride a bike or read
Perceptual-representation - enhanced recognition to specific stimuli

Question 12

Amnesia patients

Answer 12

147 patients with amnesia, in all cases their procedural memory’s and perceptual-representation where intact but the other two systems were not showing LTM is not unitary

Question 13

Sensory store

Answer 13

From the 5 senses, constantly receives information, if attention is paid to the information then the data is transferred to STM

Question 14

The studies largely involved college students

Answer 14

Doesn’t include the range of age groups
