- The Multistore model
- Sensory Memory
- Sensory register
- receives and stores info through senses
- coding- modality specific
- capacity- very large
- duration- 0.5 to 3 secs
- capacity- very large
- can be lost through decay
- Sensory register
- Short term memory (STM
- coding- acoustically (how it sounds
- capacity- limited (5- 9 items)
- can be lost through decay/ displacement
- info received from SR stored temporarily
- Short term memory (STM
- coding- acoustically (how it sounds
- capacity- limited (5- 9 items)
- can be lost through decay/ displacement
- Short term memory (STM
- serial position effect- Murdock
- first few words are rehearsed (LTM) and the most recent words go to STM.
- words said at the middle of list either gets decayed or displaced, thus there's a drop in the serial curve
- Sensory Memory
- Long term memory

- Sensory Memory
- coding- semantically
- capacity- unlimited
- can be lost through decay/ interference
- The Multistore model
- case study- KF
- Suffered brain damage- affected his STM ability for verbal information.
- could process visual information normally
- shows phonological loop had been damages
- supports WMM- shows existence of a separate visual and acoustic store
- could process visual information normally
- Suffered brain damage- affected his STM ability for verbal information.
- supporting research for STM- Miller
- investigated the capacity of STM
- participants read a series of numbers and repeated them back to the researcher in the same order that they heard.
- average digit span was 7 plus or minus 2
- number of digits had to recall increased until they could not recall them accurately
- Capacity of STM can be increased by chunking
- participants read a series of numbers and repeated them back to the researcher in the same order that they heard.

- case study- Clive Wearing
- challenges the MSM because he shows LTM has different stores- has procedural memory (play piano)
- memories of past events are not retrievable showing that MSM is not 1 store= lacks validity
- Clive was still able to walk, talk and play the piano but lost the ability to form new long term memory
- challenges the MSM because he shows LTM has different stores- has procedural memory (play piano)
- tested 733 adults who had taken Spanish
- participants not currently enrolled in a spanish course had not studied spanish for periods ranging from 1- 50 yrs
- supporting research for LTM- Bahrick
- recall declined for the first 3 years after people stopped studying
- after that, the amount of information remembered stayed similar
- showing that information stayed in LTM can be for many years
- after that, the amount of information remembered stayed similar
- serial curve supports MSM- shows STM and LTM are separate
- Limitations
- according to MSM, what matters in rehearsal is the amount of it that you do
- however, Craik and Watkins discovered that there are 2 types of rehearsal
- maintenance rehearsal is the type described in the MSM but does not transfer into LTM
- Elaborative rehearsal is needed for long term storage- occurs when you link the information to your existing knowledge.
- serious limitation if the MSM because it is another research finding that cannot be explained by the model
- however, Craik and Watkins discovered that there are 2 types of rehearsal
- according to MSM, what matters in rehearsal is the amount of it that you do
