Multi Store Memory Model

Question 1

Definition of capacity

Answer 1

The amount of information that can be held in a memory store

Question 2

Definition of duration

Answer 2

The length of item information can be held within a memory store

Question 3

Encoding

Answer 3

The format in which information is put into memory stores

Question 4

Definition of retrieval

Answer 4

Process of transferring info from LTM to STM, recalling information

Question 5

Definition of Storage

Answer 5

Process of information being held within a memory store

Question 6

Sensory store

Answer 6

Stimuli from the environment pass into the sensory register
Iconic and echoic
Holds onto information and has a duration of 2 seconds
Info is decayed if not paid attention to
Acts as a buffer and holds onto information from enviro

Question 7

STM

Answer 7

Has a limited duration of between 18 and 30 seconds
Encodes acoustically
Has a capacity of 7+/-2 items

If it isnr rehearsed information would be decayed and lost

Question 8

LTM

Answer 8

Unlimited capacity with an unlimites duration
Information from the STM is rehearsed to be transferred into the LTM
Semantically encoded
Permanent memory store

Question 9

Perterson + peterson

Answer 9

Conducted a lab experiment where people would recall trigrams , 24 ppts
To prevent rehearsal they were told to count backwards in threes or fours , untillc rhey saw a res light -brown peterson effect
when rhe interval period was 3 seconds, 80 percent of ppts were able to recall but after 18 seconds only a select few of ppts were able to rmemeber

Question 10

Evaluation

Answer 10

There is more than one type of STM
shallice and warrington’s case study of a patient called KF that had trouble on recalling digits and had a poor STM when read aloud to them , but had no trouble on recalling the digits ehen reading it themself, shows that there is another store for processing auditory and visual information
