The Multi-Store Model
Sensory Input Attention
Sensory Register
Encoding: Modality specific e.g. Taste stored
as taste
Duration: <1 second (Sperling 1960)
Capacity: Nine items (iconic memory ­Sperling 1960)
Aim To investigate the capacity of iconic memory.
Method A three by four grid of numbers was flashed for 0.05 seconds.
Followed by a high, medium or low pitched tone to indicate which
row was to be recalled.
Results On average, the participants were able to recall 80% of the letters
on the cued row.
Conclusion Since the participants didn't know which row was going to be
called beforehand but still managed to recall it well, you can
assume that at one time all of the information was held in the
sensory memory. But it decayed very rapidly.
evaluation The work by Sperling is the basis of the view that sensory memory
stores are large but decay very rapidly. Lasting 250 to 500

Short term memory
Encoding: Acoustic (Conrad)
Aim The aim of the study was to investigate the nature of coding in
Method Conrad presented participants with several series of 6 letters
visually at a rate of 0.75 seconds per letter. The letters used were
selected from B, C, F, M, N, P, S, T, V, & X. Participants were told that
they had to write down each list in the order the letters were
given immediately after the presentation (thus making this a STM
task).…read more

Capacity: 7+-2 (Jacobs and Miller)
Aim To investigate the capacity of short term memory
Method Participants were read lists of either words or numbers that they
had to recall immediately after presentation. Jacobs gradually
increased the length of these digits etc until the participant could
only accurately recall the information, in the correct order, on 50%
of occasions. Recall has to be in the correct order (serial recall).…read more

Long term memory
Coding: Sematic (Baddeley 1960)
Aim Investigate coding of long term memory and short term memory
Method Baddeley conducted two different experiments ­ one to measure STM, and
one to measure LTM. He used list of words and found that the type of error
made depended on the type of list and the time delay.
Results When recalling from STM participants made more acoustic errors. When
recalling from LTM participants made more sematic error.…read more

MSM is over-simplified ­ FK had a motorbike accident: Normal LTM but STM
capacity of two items. If STM is necessary for rehearsal into the LTM his LTM
would have also been impaired.
Lab experiments lack ecological validity, have demand characteristics and can't
apply to real life.…read more
