Multi-store model
- Explanation
- Sensory memory
- Attention
- Short Term memory
- Rehearsal
- Long term memory
- Capacity: unlimited
- Duration: up to a lifetime
- Capacity: 5-9 pieces
- Duration: 20-30 seconds
- Capacity: very limited
- Duration: 2-3 seconds
- Evaluation of the multi store model
- Rehearsal not always needed
- The multi store model suggests rehearsal
is necessary for storing information in the
LTM . However some every day situations
are remembered without being
rehearsed.
- Support
- The primacy and recency effect
supports there are two different
stores for the short term and long
term, supporting the multi-store
model
- What about processing?
- The multi-store model doesn't take into
account the level of processing and the effect
this may have on storage. F.g. information
semantically processed may be recalled and
stored better than phonetically processed
information. It may not be rehearsal.
- Study
- A: Evidence to support MSM
- M: Participants had to learn a list of words
presented one at a time, for two seconds
per word, and then recall the words in any
order.
- R: Prmacy and recency effect
- The words at the end of the list were recalled
first (recency effect). Words from the beginning
of the list were also recalled quite well (primacy
effect), but the words in the middle were not
recalled very well.
- C: evidence ST and LT are
two separate stores
- Evaluation of study
- Learning list of words- artificial - lacks
ecological validity - not reflective of
real life
- Supports the multi store model, as the primacy
and recency effect shows there are two separate
memory stores
- Practical application
- SS: capacity of STM is approximately 7 chunks
- Helped us with keeping certain important
things we have to learn within that limit
- E.g car registration and pin numbers
- SS: information needs to be
rehearsed to be stored in LTM
- Helps knowing how to revise effectively.
- To recall information it needs to be rehearsed
