Who devised the multi store memory
developed by Akinson and Shiffrin
1 of 38
What does the multi store memory view the process is for memory
Sees memory as flowing through a series of storage systems
2 of 38
What is the Sensory register
It is the Automatic response to sensory info from sensory organs and 1st storage system in MSM all LTM info passes through the SR
3 of 38
what is coding
form in which info is stored
4 of 38
Where is info stored through coding in the MSM
Separate stores for different sensory inputs (Echoic = audio, iconic=visual, hapic =tactile info, gustatory=taste and olfactory=smell)
5 of 38
What happens through SR coding to things that are paid attention
goes to STM, anything else fades leaving no lasting impression
6 of 38
What did Crowder find in relation to SR coding
found SR retains info Iconic store=few milliseconds, 2-3 secs in echoic. Shows there are different sensory stores
7 of 38
What is capacity
how much info can be stored
8 of 38
what is the capacity of SR in MSM
- Large, info unprocessed, highly detailed and everchanging format.

What did Sperling find in terms of SR capacity in the MSM
3x4 grid of letters for 1 20th of a second asked participants to recall. Lines given different tones. Recall high showing capacity of SR is high

What are the 3 parts of the MSM
Sensory register, Short term memory and long term memory
12 of 38
What is duration
How long info can be stored
13 of 38
what duration does the SR in MSM have
Limited duration, duration for each not consistent across different stores.
14 of 38
What did Walsh and Thompson find in relation to SR duration
Limited duration, duration for each not consistent across different stores.
15 of 38
What did Treisman find in relation to the SR duration
identical auditory messages to both ears with slight delay. Noticed delay if 2 seconds or less. Echoic store limit of two seconds which is different to the iconic store
16 of 38
What is short term memory
Temporarily store info being thought about and receives info from SR.
17 of 38
How is information coded for STM of MSM
Info is encoded into a form STM can process. This can be
visually
acoustically
or semantically.

or semantically.
18 of 38
Who found that info is mainly coded acoustically
BADDELEY Study

What did Posner and Keele find regarding codig for STM in MSM
visual coding faster at assessing A followed by A than A followed by a as visual change.
20 of 38
What is the capacity for STM in the MSM
Limited, 5-9 items stored, and capacity increased by chunking (grouping info into larger units)
21 of 38
What did Jacobs find in relation to capacity in the STM of the MSM
increased numbers 1 by 1 and asked to recall.
50% of tasks failed.
Numbers capacity 9 letters 7.
Criticized as no everyday relevance to mundane tasks.

22 of 38
What did MILLER find regarding capacity in the STM of MSM to support JACOBS
5-9 chunks can be held at once
23 of 38
What did SIMON find in regards to Capacity of STM in MSM to differ from JACOBS
varies depending on info
24 of 38
What did DANEMAN and CARPENTER find in regards to Capacity of the STM in the MSM
individual differences.
Between 5 and 20 chunks dep on reading comprehension.
Between 5 and 20 chunks dep on reading comprehension.
25 of 38
What is the duration of the STM of the MSM
Max 30 seconds, extended by rehearsal of info if done long enough will move to LTM
26 of 38
What did PETERSON AND PETERSON find in regards to duration in the STM of the MSM
nonsense trigrams count backwards with the last 3 large digits over varying time.
90% recalled correctly after 3 seconds 5% after 18 secs.
STM 20 to 30 secs.
Criticisms, lacks mundane everyday aspect. And different trigrams used each trial leading to i

27 of 38
What did MARSH ET AL find in relation to Duration in the STM of MSM
if not expecting to recall 2-4 sec STM. STM affected by time taken to process info
28 of 38
What is the LTM of MSM
LTM all info stored processed for more than 30 secs. Passes through SR and STM first. Different types of LTM. LTMs can be strong (no prompt) or Weak (prompt).
Memories are not always accurate or constant see forgetting LTM.
Memories are not always accurate or constant see forgetting LTM.
29 of 38
How is info coded for the LTM of MSM
How info is shaped into memories. Stronger the deeper the level of processing the stimulus is when happening.
Verbal material sematic however coding can be visual and acoustic.

What did FROST find in regards to coding within the LTM of MSM
16 drawings in 4 categories with different visual orientations.
Order of recall suggested visual and acoustic code was used.

31 of 38
What did NELSON and ROTHBART find in relation to the LTM of MSM
acoustic coding also occur in LTM as made mistakes when recalling similar sounding words
32 of 38
What is the capacity of the LTM of MSM
Potentially unlimited and info lost is due to decay and interference not capacity.
33 of 38
What did ANOKIN suggest in relation to the capacity of the LTM
humans not yet unlocked the full potential of their brains 1.(10.5 x 0)
34 of 38
What did WAGENAAR find in relation to capacity of LTM
Diaries of 2400 events over 6 years tested recall of events rather than dates. Excellent recall but is a case study so not representative.
35 of 38
What is the duration of the LTM
Depends on individual’s lifespan. Longer duration is originally well coded. SMT info needs to be rehearsed LTM info does not
36 of 38
What did BAHRICK find in relation to the duration of LTM
400 participants 17 to 74 set of photos and names. Some of which ex school friends. Asked to recall identity of them.
Those left in last 15 years 90% recall. 48 years previously 80% of names and 70% of faces memory for faces lasts longer
Those left in last 15 years 90% recall. 48 years previously 80% of names and 70% of faces memory for faces lasts longer
37 of 38
What did GOLDMAN and SEAMON find in relation to the duration of LTM
identify odours of everyday products from last 2 years or childhood. Identification by name better for recent.
Identification by scent better for older odours.
Olfactory info last long in LTM.
Identification by scent better for older odours.
Olfactory info last long in LTM.
