Here's a taster:

Flow of Information
Encoding- the way information is stored
Storage- holding information
Retrieval- getting information when needed
First we take information from the stimulus and encode
it. It is then stored in a part of the brain and when the
information is needed we retrieve it from this part of the
brain.…read more

ATKINSON & SHIFFRIN
Sensory Short Long
Information Term Term
Store Memory Memory
First we receive information from the stimulus as we pay
attention causing it to enter the Sensory Information Store.
We have to pay further attention to make the information
enter the STM. From here, we have to rehearse the
information over and over again to make it enter the LTM.…read more

Multi Store Model
PETERSON & PETERSON
Aim: To see if rehearsal is necessary to hold information in the STM
Method: Participants were shown 3 letter words (i.e. WKG, THY)
and were asked to remember them. Immediately, they were
then asked to count backwards in 3s from 100 for different
lengths of time. They were then asked to recall the trigrams in
the correct order.
Results: It was found that virtually all the information was forgotten
after 18 seconds.
Conclusion: Rehearsal is necessary to hold information in the STM
(duration is around 18 seconds)…read more

Multi Store Model
PETERSON & PETERSON: Evaluation
Nonsense syllables are not the type of memory tasks in real life
therefore it lacks mundane realism
It was a lab study therefore it lacks ecological validity as there
was high control over the variables
It helps us understand why postcodes and car number plates
never exceed 7 chunks of information (capacity of STM)
PETERSON & PETERSON: Practical Application
When revising for an exam, you should repeat the information
over and over again so it enters the LTM (making the
information easier to remember…read more
