Multi Store Model Flashcards
Encoding for sensory memory (MSM)
A register for each modality: auditory, visual, haptic, olfactory, gustatory
Encoding for short term memory (MSM)
acoustic
verbal
Encoding for long term memory (MSM)
semantic
acoustic
verbal
Mode of representation for sensory memory (MSM)
modality specific
Mode of representation for short term memory (MSM)
acoustic
verbal
Mode of representation for long term memory (MSM)
semantic
acoustic
verbal
Storage duration of sensory memory (MSM)
visual - 200-500 milliseconds
echoic - 3-4 seconds
Storage duration of short term memory (MSM)
15-30 seconds
Storage duration of long term memory (MSM)
20 mins - lifetime
Storage capacity of sensory memory (MSM)
unlimited but most decays
Storage capacity of short term memory (MSM)
5-9 items
Storage capacity of long term memory (MSM)
potentially unlimited
Forgetting in the sensory memory (MSM)
decays if not transferred into STM
Forgetting in the short term memory (MSM)
decays if not rehearsed or displaced
Forgetting in the long term memory (MSM)
decay if not rehearsed
Retrieval in the sensory memory (MSM)
Scanning
Retrieval in the short term memory (MSM)
Rapid sequential scan of info
Retrieval in the long term memory (MSM)
Largely semantic search
Strengths of the Multi-Store Memory Model
Miller - he found that the STM could hold 5-9 items (Miller Magic Number 7) supports MSM
Blakemore - Clive Wearing had memory impairment. STM was intact but LTM was not. Supports that they are different sections
Weaknesses of the Multi-Store Memory Model
Case of KC - After a motorcycle accident that caused memory loss, he could recall facts but not personal events. Suggests that the LTM has at least 2 stores
Case of KF - After a motorcycle accident KF had impaired STM for verbal info but the memory for visual info was unaffected. Suggests separate STM stores
