MSM Revision
Memory
There are 2 kinds of memory: Short term memory and long term memory.
The Millers Memory test shows that the capacity of the short term memory for
most people is 5 to 9 items. The duration of short term memory is thirty
seconds.
Encoding
This takes place during the presentation of material and creates a memory
trace.
Acoustic
The sound of the word. The memory of the word is stored by the sound.
Semantic
The meaning of the word. The memory stored because of the meaning.
Visual
How the word looks. The memory stored because of sight.
Encoding > storage > retrieval
MSM
Sensory register, the memory is forgotten if not paid attention. The duration
of the sensory register is a fraction of a second > short term memory ,
memories passed on to the SR because they have been paid attention to and
the duration of the STM is 30 seconds >Long term memory, memories from
the STM are passed on to the long term memory because they have been
rehearsed. The capacity and the duration of the LTM is infinite.
STM usually encodes acoustically
LTM ­ Usually encodes semantically
Glossary
Capacity ­ the volume of substance something can take
Sensory registry Sense organs

Theories that support MSM theory of memory
Primacy/Recency
Primacy/Recency is an experiment where participants are given a list of 20
words in succession and the experiment is interested in where the most words
are remembered.…read more

Here's a taster:

Clive proves that MSM is true because the part of his brain that was damaged
has stopped memories from being transferred from the STM to the LTM.
It doesn't prove that MSM is true because the fact that he can still play piano
and recall his wife means that he still has parts of his LTM left which means
that the theory of MSM isn't complex enough and that there are different kinds
of Long term memory.…read more
