Multistore Model of Memory


 

Coding

Capacity

Duration

Sensory Register

Coding is Modality Specific

Potentially unlimited capacity

Limited duration of a few seconds (modality dependent)

Short Term Memory

Codes acoustically

Limited capacity of 7±2 items

Limited duration of around 18 seconds, but with rehearsal is increased to 30 seconds

Long Term Memory

Codes semantically

Virtually unlimited capacity

Potentially unlimited

 

(+) Research to support

(+) Gave psychology a way to talk about memory with research being based on the model

(-) Over-simplified

--> assumes each store works as an independent unit

(-) Doesn't explain memory distortion

(-) Doesn't explain why some things may be learned with a minimal amount of rehearsal

(-) Rehearsal doesn't always transfer information into the LTM
